I have a little project where I want to try to start a car that has been sitting for 5+ years. It's a Honda Civic 1992 with the 1.5.

The mongoloid who parked it that long ago stripped the crank pulley bolt. I need a tap and a new bolt, but I am having a hard time figuring out the threads.

There are 20 threads per inch, and the bolt measures 0.5443" across the threads. Is it a 9/16-20? I am concerned for two reasons.

1. 5/16 is pretty far from .5443.
2. Everything on the car is metric, but I cant find a metric bolt close the same size.


Is it actually a M14-125?

Cross posting on /O/, thanks friends.

>>1364852
From what I read a long time back you can get it in bulk online, then there is a method to dry it out after prolonged use.

>>1364783
now I'd like to see them shoot another round

>>1364880
>Honda D15B7 crank bolt p/n 04133-P01-305
Image search the p/n and they all quote it as "14X29"

>>1364880
I won't bother asking why
I can't answer your question.
I do want to wish you good luck.
But
If you are having to tap and new bolt why do you care what the old bolt was, if it's fucked there won't be anything to tap.
Unless you mean to just clean the threads rather than tap a new bigger hole?

>>1364890

Thanks man, that helped a ton, I ordered it. The bolt is 29 mm long, so that explains that number. 20.32 tpi is 1.25 mm, so I am ordering a 14 x 125 tap and hoping for the best.

wish me luck.

How do I make patches like pic related? Could I just use some old fabric and transfer printer paper?

Alright I got a project brewing in my mind. I do scroll saw projects and I'm now moving into drawing my own work. Some things would be easier to trace and have an outline to work with while designing. This is where I'm lacking in the knowledge of what even to Google. I was thinking getting a monitor and stripping it to just the screen and having an hdmi input to put images onto the screen, then plexiglass over it so I could draw the outline on paper over it. Is this fucking retarded or would it work?

>>1365080

Just a thought, maybe read the label on the drive to see the power draw. It's measured in mA if that helps

>>1365162
And also, why does it matter? Most slimline drives will power between 500-1000mA, just buy a 2A adapter and be done with it.

>>1365009
>>1365004
use bismuths diamagnetism to displace the magnets field enough so it won't topple over another.

>>1365165
I don't want a slimline or USB drive.

Total brainlet here, what is the easiest way to fix the shower curtain clip to the wall so that it doesn't move whenever I pull the curtain? I've thought of cable ties but there's nowhere to fix it to that will stop the curtain moving

>>1365441
Well, considering there's nothing to anchor anything to on the wall, and if you're a brainlet you probably don't want to go drilling tiles to mount stuff, how about stitching a few of pic related onto the edge of the curtain?

First day here?

Recently got into /tg/ and have decided I want to make a better game board for myself. Plan on using 2'x4'x¼" mdf and routing V-grooves 1/16" deep to make a 1"grid over all but the outermost 2" of the sheet. Once that's complete I plan to flock (the grass material modelers and wargamers use to simulate grass on their pieces) the surface. Knowing mdf swells like week-old roadkill when exposed to water, I wonder what pva glue should I use to adhere the flock to the mdf?

Alternatively, and this will help me with the second board I plan to make (stone/dungeon floor themed), should I put a couple of rattle can base coats down before I go ahead with anything else?

I need a long allen key in order to unscrew the heatsink that is fixed to the motherboard in my computer processor. I ordered this one last week and it arrived today, but it is a standard size. Arm length 21mm, body length 61mm. I don't know where the 30mm dimensions comes from in the ad description. Am I missing something here? Did the seller just post the wrong key? I contacted him just now waiting on a response.

>>1365779
Looks like the ad says 3.0mm, not 30mm. Maybe it's the diameter of the shaft, i.e. the actual size of the bit in metric?

>>1365791
That is, the seller correctly wrote the size once, but missed the decimal point later in the description?

>>1365791
It has two numbers - 3.0mm and 30mm. 3.0mm is the width of the bit. 30mm is presumably the length. Except the length is actually 61mm by my calculations. Which is like a standard size. I need a 100-120mm length key for my purpose.

>>1365792
Possibly. The image is also wrong. It looks long. But the item I received is a stubby key.

LCD screens and monitors diffuse really widely (so they’re easy to look at) so you’re lines will get fuzzy even in a thin piece of plexiglass. Any easy solution would be to just print the shit you want on paper and glue it to your work. An 11x17 printer and ledger paper aren’t that expensive. The other option I can think of would be one of those cheapy projectors and some /diy/ mounting jig to show your lines and you can draw them on the work by hand.

Hey,
can someone help me with this bathroom fan?
I removed the lid to clean it and accidentally pushed these little fins and they closed up.. so now I can't open them and I don't think it will be okay to turn it on as it is.

Thank you to anyone that can help!

>>1365865
Ha, apparently I'm not very smart! It's automatic and the poor thing just needs a while to close and open them.

But still I'd like to think that I got a bit smarter today, I just figured out how fans work. At least I've got a clean fan and a bit more knowledge in my head now. Heh.

OK, so is there a primer or guide for creating your own PSU for a project? I need 5v and 12v.

Itll have 5v and 12v on it. Lots of guides on how to do that.

What are these called?
Im looking at "latch" and "clasp" and they arent showing up at lowes or home depot or even hobby lobby. Do they just not have them or is there a different name?

>>1365900
the big red thing on the top right is an electrical switch, there is a white piece of plastic connecting the switch to each fin, probably so they operate together.
presumably there is a cord to pull that will activate the switch and open the grille.

there is no cord in the image, possibly it is part of the cover that has been removed and replacing the cover will force the fins back into the correct position.

if they opened by themselves presumably when you closed them there was some force applied by the switch mechanism that was trying to keep them open again.

I have a 2 channel amp and some speakers. Wanted to re purpose them for dining room audio at work but boss wants radio station. All I need is a radio with line out to the amp. Don't a giant receiver or anything. Just a small component to pump fm to the amp. All I seem to get in Google is rechargeable pocket radios.

how can I look for fluorescent light bulbs that emit a warmer, more natural color instead of straight up blue light?

>>1365983
Hi, thanks for the reply.
This is the first thing I thought too, I tried moving the white plastic that connects them but it was not having any effect, also the lid doesn't interact with the rest of the fan in any way, it's just a lid.
What I found out is that the shutter is controlled by a solenoid and it opens up automatically when you turn on the fan. But it takes like 20-ish seconds and basically it works but I thought it's supposed to be open at all times. lol
Silly me. Thanks again for the reply, have a nice week!

I've had my car stereo flopping its guts out for a week now because I'm too retarded to figure out how to install this bluetooth adapter.

The adapter plugs in on the back of the stereo (pic related) but it also comes with a red 12v wire and a black grounding wire. The "instructions" say just connect the red to my stereo and ground the black. How the fuck do i connect the red to my stereo? And how the fuck do I ground the black?

>>1366022
see the fattest wires there? the yellow and black? yellow is by convention 12V. black is ground. your cars battery is connected to the metal frame of your car on the negative terminal. this makes any metal surface bonded to the frame of your car a ground connection. just connect the big yellow wire on the stereo to the red wire on your dongle and the black wire to the black. then insert radio into anus.

>>1366043

But how does an idiot connect them?
They are already connected to this harness.
Do i cut the yellow and black wires somewhere before the harness to make the connection?

can i use wall transformer adapter to power a small circular saw

and can be any transformer as long as it have enough power?
or would the motor draw too much current and max the transformer or something?

>>1366251
or would i need a resistor of like 20w 4ohm.
since it used 2 versapak batteries of 3.6v 2100mah in series for 7.2v 2100mah. and lets say i use a 8v >2100mah DC transformer

Good news: The DC motors used in power tools are very adaptable to the voltages they can take. So, you just need to get close to the voltage and you will be fine. 8 volts is a sure thing and maybe even 10 volts is okay. 12 volts is probably pushing it but you never know.

Bad news: The DC motors in power tools have crazy high amp draw at stall speeds. A little thing that that could easily pull 15-20 amps if you get the blade gummed up while cutting a board. Even under normal operation, you are probably looking at 5-10 amps while cutting. A power supply that can output that is gonna cost more than a used Skil circular saw off of craigslist.

>>1366251
Needs too many amps and it would still be shit. Cheapest circular saw at my local Lowe's is a 120V 13A Skil 7 1/4". Even being the worst saw you can find it's plenty fine to use properly(as in, not stupid shit like throwing a concrete disk on a circular saw).

>>1366290
hm i ordered this

>>1366293
>>1366290
nvm not enough amps

>>1366295
Looks like that saw just uses two 18650s in special cases. So, 20A max, but there's no way an old B&D tool uses nice cells, and even if it did, it would only be at 144W at rated voltage. I say just start at 8V and step it up until it works or lets out the smoke. Worst case you still don't have a working saw.

>>1366233
>>1366244
I still have trouble believing that this works.

I need to be able to power 3 things from the supply. 5v at 2.5A x 2 and 12 v for the DVD R drive.
Trying to figure out if I could build something and power the whole thing by a wall wart

>>1366366
The best way would to get a 12V wall wart capable of your total power requirements. Then get two DC/DC switching regulators which take that 12V and drop it down to 5V. Make sure they can handle 2.5A. They will likely be a power so package so make sure there's proper heat sinking. The chips plus the other components should fit within the size of half your thumb. Don't bother breadboarding them. Solder them on a protoboard because the extra resistance and capacitance in breadboards cause the regulators to perform poorly.

In Europe, where we have a standard size, so it's used in litterally all cargo not in a container, you would just go around local retailers until you find one that have some he will give you.

Not everybody want to give them away, especially since standardized pallets are actually worth something in resale or return. But they're discarded all the time when they're showing sign of aging. In my store you could get 2-4 each week from us.

>>1366415
Yeah you essentially want to build one of those. It's much cheaper to build your own. The total cost of components is $5-10. The switching regulators also come in fixed 5V versions so you can save on 2 to 3 components.

>>1366813
Yes, but it is as intelligent as stacking 4 chairs on top of each other instead of using a ladder.

Its acting not how Id expect them to.
Speed barly works. highest setting is only slightly faster slowest setting. range should be 2k-12k rpm or something.
It wont sand anything even with 60 grit.
I took off the plastic ring brake thing and it goes faster, but still it doesnt have any power. It will sand if you hold it at an anlge, but it leaves circle scores and you might aswell just use an angle grinder.
without the brake, its still so weak that if I set it on wood and start it, it just sits there and wobbles without spinning.
with the brake, its so slow and weak that I can put my hand on it and it wont hurt.
Someone else used it for drywall or something, its full of white powder allover the windings. Ive already cleaned the speed control circuit.

Is this thing fixable or just junk now?

Pic related i was suppose to cut red but i cut yellow
Red is accessory power yellow is constant

>>1367157
well first of all thats stupid you are blowing air into itself, use something with high thermal conductivity, a heatsink, to draw heat out of a large or awkward area into a smaller area you are actually cooling.

but if you actually want to go ahead with this just realise that the impedance to air flow should increase. ideally you calculate it out so the pressure ratio is equivalent at each point between exiting the slit vs continuing.
or...just think the more pressure you can dump in the less bad it will be.

sorta interested in this one too.
reminded me that I have on old motor that starts most of the time but sometimes when I plug it in it wont move until I hit it with a hammer. It doesnt matter where or how hard its hit, just aslong as its hit. If I rotate the pully even slowly and gently it will take off aswell.

The genius who built this apartment I'm in thought it would be a great idea to build it 10 away from a major road and put giant windows on it that suck at insulating or blocking sound. Would putting up blackout curtains be a good idea for blocking sound and heat or should I look at doing something else?

>>1367380

They won't do shit for sound. They'd need to be white on one side to reflect most of the heat.

You'd need curtains specifically made for sound attenuation (see: made out of mass-loaded vinyl) to have any noticeable effect on noise level.

All switching regulator ICs have application schematics, part values, and even part numbers sometimes. Some of these chips even have detailed application notes which explain in profuse detail what each component does and design considerations. Those can be hard to find. Take a look on the manufacturers website first.

For example take the LM2576T-5.0 for example (https://www.digikey.ca/product-detail/en/texas-instruments/LM2576T-5.0-NOPB/LM2576T-5.0-NOPB-ND/212636).). It is a switching regulator that can accept 4V-40V input, and outputs 5V at up to 3A. In the datasheet, you can find the schematic which says that you need an input capacitor, a catch diode, and output choke (inductor), and an output capacitor to function. In section 8, the purposes and function of those components are explained and some part numbers are listed.

You can learn a fuckton from datasheets and application notes once you have a solid foundation in electronics.

I have a bathtub with these faucets. They are weird because you have to turn them inward to open, that is the hot water knob must be turned clock wise, and the cold water knob must be turned ccw (not my house, renting etc)

About half the times I take a shower the hot water knob will close itself slowly. I can see the knob actually turning on its own. My landlord doesn't really do any of the stuff I've asked for and I doubt he is going to help with this

Is there some clever way to fix this without having to hold the knob down on my own when it starts turning?

hey anon with bathtub with these faucets....symptom you relate isn't weird at all...follow here..handles are attached to "stems"which can turn in / out for water thru shower or tub spout. these stems are captured into the valve fitting with a 'packing nut" *don't any go all queer on that, NO. to prevent water escaping. The stem nut needs to be tightened to keep the H or C valve stem from turning due to water flow internal. Old plumber here. Take handles off...see packing nuts on each stem...NO Don't comment, Tighten said packing nut with crescent wrench or channel lock pliers... NO don't ya'll comment..on stem. this tightening on stem will prevent stem being "turned" as water moves past inside of valve, put handles back on. ..you will feel increased resistance when turning handles to on and off positions, good luck anon.. hope this helps anon...

I'm building my own desk, learning as I go, only halfway thinking through parts of it and having to overengineer other parts to compensate. Y'all have been helpful on bits so far, so I thought I'd pitch you my latest issue.

So the desktop is a 16 gauge tube steel frame, it's going to be mounted to the wall on the rear and right, and then it has another tube steel rectangle to be used as the left leg. My first big fuckup was 16 gauge steel. I didn't want fasteners poking out the bottom for me to run my legs into, and you can't thread much into 16 gauge... So I'm going to try flow drilling the hole with an AliExpress drill in my drill press so that I can use an 8-36 forming tap.

My latest issue is that I should have made the leg a half inch shorter. The desk is on carpet, and that'll sink in a bit as time goes on, so I need some kind of adjustable feet to compensate, but I only need maybe 1/4"-3/4" adjustment range, and that'll all be mounted in place and squished under carpet, so I need to adjust it from the top. It also needs to be wide enough to not just punch through the carpet. Do you guys have any good ideas?

What is the difference between an e-clip and a snap/retaining ring?

From what I gather they do the exact same thing, in the exact same way. You just remove them with different tools.

Is it possible to spin multiple pulley/rope lines from a single motor? I'd like to have multiple overhead rope lines (eg a clothesline) all being moved from a single source.

>>1364783
Like my pallet shutters?

>>1368186
An E clip is more usable due to it being easier to apply. Retaining rings are good for when you have a low tolerance application since they hide away better. Usually it comes down to specifically what works best given your situation and your preference.

LED projects can be worthwhile if you come up with an ambitious project. Try running LED strips along the baseboard of a room and having the colors synch to the time of day.

If you can't find something to work on, then it has more to do with your creativity and motivation, not a lack of "meaningful/provoking" projects.

Video walls are desktop PC duty. You can do it with a consumer GPU. Pro GPU has the advantage of having a range to adjust for very large or very wide video wall. For example, consumer GPU may have 8192x8192 range before it won't go any further, while pro GPU may have 12228x12228 range.

I want to make my phone less hot when I use it for afk-gaming overnight. I tried putting my phone upside-down, and put two heatsinks in pic related on top of the back cover on the what I assume where the cpu is, because it's the most hot place. And blow them with regular fan.
I didn't use any thermal pad/grease at all, since it would ruin the back cover of my phone. I'm just put it on top of it.
Do you guys think it's enough to cool my phone or would a dedicated cooler pad for smartphone better?

>>1369461
*dedicated cooler pad like in pic related

>>1369461
You'll need to use some kind of thermal compound to really have any success. They make adhesive pads that work okay for lower temperature stuff, and you can probably get it to adhere well enough but still pull off by just handling it a bit and wearing it out with oils from your hands. Or just use thermal paste, it wipes off.

Also you're going to destroy your battery. Heat is what kills them the most.

>>1369506
Will the compound do anything harmful to the phone functionality? Like, blocking signal or something?

>Heat is what kills them the most
I know, that's why I try to make something to reduce the heat. As of now, I don't leave it plugged charged overnight, just leave it on battery until it dies. So far with just putting the heatsinks on top of it + fan, it only warms a bit, never gets too hot. My aim is to make (or buy) a cooling system that will let me to let it plugged on without overheating both the cpu and battery.

>>1369506
Also, regarding to my original question, is my logic wrong or not, metal meets metal + regular table fan would still be better at reducing heat than plastic meets metal even with dedicated fan (like in the second pic), wouldn't it?

>>1369511
Draining the battery too low is the other thing that kills batteries. I don't know if the compound will mess with your signal, that'll depend on antenna placement and what compound you use, but I would be pretty surprised if any of them really affected it. The heat sink is more likely to be the issue, that big chunk of metal.
>>1369513
Comes down to how effective each material is at transferring heat, how well they make contact with each other, and how much airflow everything gets, but I'd think the metal meeting metal is your best bet. Advantage to the pre-made pad is that it's simple, just drop it on and let it work, versus fucking around with thermal compound and heat sinks.

>>1369462

Anyone have experience with these LED strips?

I would like to power just a few lights (maybe 4-6 likely not more than 10) via battery, but I'm not sure how to get it to work as the battery would need to be fairly low profile. I've been trying 2 button cells which I would think should be enough for a few considering you can by prewired strands that way but over lower power LEDs. Thought maybe a few brighter ones would work over many dull ones.


>>1369461
Buy a cheap Kindle Fire, sideload on Google Play, keep the brightness as low as you can, and enjoy. Larger space and lower power cpu/gpu will heat up less and if it kills the battery you are only out a very cheap device or just have to use it only plugged in, which you would be overnight anyway.

Phones despite all their power wanking these days are badly designed. They waste a lot of that power, and struggle with heat because they want to shove something that would be at home in a Chromebook into a palm sized razor thin device that half the time is sealed for waterproofing into a hotbox. The giant resolutions aren't helping either.

It doesn't make sense to put a flashlight with the pliers drawer, but it does make sense to put it in a drawer with the box cutter, pencil, pen, lighter, etc.

It's not fried, you blew a fuse somewhere at best. Check your fuses

You can just cut it and solder on a new tip. Pretty day one stuff as far as difficulty goes

It's the capacitor 100%, had the same problem with mine. You'll see numbers like 45/5 or something like that. In that case the 45 is the kicking power needed to get the fan in motion from a dead stop, and the 5 is the small energy needed to keep it moving once it's in motion. Pretty generic explanation but the high side of the capacitor has gone bad. Replace the capacitor, $40 tops and 10 mins of work

I'm trying to find a wrench/key I can use to tighten this nut. Unfortunately I don't know what it's called. Anyone know what kind of nut this is or an appropriate tool I can use on it?

>>1368138
Cover it with fiberglass resin, throw on some fiberglass if you want. It's what boats are made of and they only rot when water gets between the hull and floorboard. Otherwise they are rock solid even though they're constantly submerged in water

>>1370635
Here's another picture from above.

>>1368247
Look up gear train, one motor in the middle can drive multiple shafts with ropes wrapped around the shaft. Harbor freight sells pulleys good enough for a clothesline

>>1370526
Put poly over the wood as a protective layer and you're good to go

>>1370635

Looks like something that industrial sized snap ring pliers could remove. For a one off job put a flathead screw driver in the slot and tap it with a hammer to spin it

I want to put two wedge bolts in my concrete ceiling to make pull-ups possible in-house, but I want it to be safe. Would two 500kg each hold me (~100kg) safe or would/could they 'wiggle' loose?

>>1370642
Thanks for the reply, but unfortunately it's not a one time thing, and I need the appropriate tool for this because these nuts hold gears that spin at 540 to 1000 rpm in place so they need to be VERY tight. So far I've been using the tool in the picture to tighten them but it destroys the nut and it really is a shame. Thanks for the help though, appreciate it.

>>1370686
Threadlocker and a jam nut? Or use that wire tie stuff that they use on jet engines.

>>1364783
why is there no apparent rifling in that barrel?

>>1365963
they're called "hard case locks" and are commonly used for building boxes for pa stuff

best way to salvage this old hammer?

can i just cat the end of the handle where it broke and sand it till it fits snug and then put a wedge in the top, or do i need to get a new handle?

>>1370764
You can do that, but if the handle has snapped it can indicate the handle has degraded. It might be better to get a new handle.

>>1370764
Have hammer like that. Get a new handle.

Electrical question:
Almost everything with a speaker plugged into an outlet in my house started buzzing last night. Phones, computer speakers, my granddad's organ. They only buzz when powered on and its the same sounding buzz all over. Any idea what could be causing this?
We're for sure calling an electrician soon I just wanna know if it's something serious.

Sorry if the question doesn't fit but this board/thread seemed close enough. i didn't wanna make an account for an home construction forum or something.

>>1371091
You're definitely in the right place.

It sounds like there is a source of EMI in the area. Did you just install a new piece of electronics somewhere? Did your neighbors? Did you get a crappy Nokia phone? Basically, it sounds like somebody in the area is operating a piece of electronics that is generating electrical noise that is being picked up by your speakers. It's probably not really an electrical problem with your power lines, more likely is a microwave or amplifier or some other piece of electronics in the area that is generating electronic noise.

>>1370888
Once it hardens yes. If it was toxic we wouldn't have it in our homes on wooden table tops where we eat.

Guys I'm a cheap peasant who has made full use of dollar store pliers for over a decade of abuse, I don't know 'good quality tools'. I've heard some people complain about cheap tap and die sets being the worst thing you could ever cheap out on while others have said that they've had good enough experiences with harbor freight and aliexpress chinesium. I just need to do some stupid crap with threading 3/4'' aluminum conduit and maybe an aluminum plug for it. I have no idea what cost should be expected for usable taps and dies for this, I've seen some chinesium listings that reviewers said couldn't even start cutting and stripped themselves immediately.

pls halp, what are good budget taps and dies?

>>1371313
My cheap taps/dies have mostly shit themselves the first or second time I've used them.

>>1371313
I've only used small stuff, think #8 or smaller, but my cheap taps have been fine. I've made sure to go straight (tap guide in a drill press), tap 1 turn and back out 1/2 turn, and use plenty of tapping oil. Never had issues. Aluminum is soft, and if you're doing just a few pieces, I'd gamble the chinesium taps. Past that, I dunno, good "good tap brands" and see what the big tool forums say.

>>1371313
The people who complain about cheap taps are the ones who tap 3" thick harden steel on a regular bases, and the ones who have no problem with cheap taps are the ones who tap soft metals (like aluminum) and use the taps to fix damaged threads on small screws and bolts. I personally have a dirt cheap set of taps from harbor freight, and each time I used them I've had no problems at all. If you're super worried, just make sure you use a lot of oil and back the tap out every half turn. Just know what the limitations of your tools are.

So here's the situation:
Near where I live there used to be those medium-sized concrete wells that used to contain the fire hydrant in case of forest fire.

But recently many of them have been emptied out and replaced with better working ones so they're basically left abandoned all over the place.
They're between 1 to 4 meters deep, all concrete.

The question is: what fun things can I do with them?

Hi. I've got a pen here with a metal casing and some company logo etched onto it. With just some light scratching the logo wipes off. But I'm wondering what exactly is the material that the logo is made of, and is it possible to imprint my own crude label onto the metal? How is it done?

>>1371454
if you can scratch the logo off, it's not etched.

I have some cabinets suspended by some long bolts anchored in the ceiling. I want to raise the cabinet a few inches. I think I can accomplish this, but I'll have a few inches of bolt coming out that I want to get rid of. I think using bolt cutters would be too high impact in this situation. Is there such a thing as a pipe cutter type tool that will go all the way through a bolt? What is the right method?

Use a hacksaw, then file the sharp edges.

I have these two DeWalt drills about 20 years old. One of them 12v and the other is 9.6v. The batteries are nearly dead. Is it better to get new batteries or new drills? I have not had any issues with either drills and use them a few times a year at most.

>>1371535
new drills and find a 12V power adapter and make one of the old ones a corded drill by clipping on the 2 wires to the terminals meant for the battery..

>>1371112
We haven't had any new appliances or anything, at least not around the time it started.
The nearest house is at least 100 yards away, could interference like this travel that far?

I have two outlets that are supposed to be connected with eachother but i broke the wires apart. They were held together if i recall with some piece of spiral shaped metal and a rubber cap... but i was wondering. Cant i just solder it? Or is there too much potential electricity running trough it to be able to safely do that?

>>1364852
The cheap and easy way to get desiccant -
Go to pet store
Find cat aisle
Find crystal-type kitty litter (whiteish crystals, often with the odd blue crystal)
Buy it - it's silica gel. It needs reconditioning (hour or so at 90 degrees C) when the blue crystals are no longer blue.
There are no bonus points if the cat craps in your toolbox, however

>>1366966
Marine stores, fiberglass places, and if you look in Bunnings, paint section, where they have all the fillers and things - they have casting resin (Protite brand).

how would I go about drilling a wide hole into an angled surface that fits a screw head inside, and a smaller one in the center of that for the rest of the screw, while going into the other piece of wood?
or would cutting out a notch instead of drilling the bigger hole be better?
this is with a hand drill btw

might be living out of my car soon. would like to be able to keep as much stuff as possible. how difficult would it be to make a utility trailer like this waterproof enough to keep stuff in it (with the stuff also inside plastic containers / covered with tarp) without getting ruined?

>>1371769
Clamp another angled piece of wood to the top of it and drill through both of them. Use forstner bits if it hole has to be particularly wide.

>>1371778
forgot pic

>>1371779
thank you anon, just one more question, which hole should I drill first? is this something to worry about at all?

Ive got a baseball hat thats seen a lot of head sweat, its basicslly turned white
how do i clean it so it looks new again?

>>1371778
>>1371781
Unless its enclosed its going to get wet, even if its covered
depending on where you live you might want to get a enclosed trailer

>>1371786
Depends what bits you use, if you're using forstner bits, I'd drill the bigger hole first it'll leave a flat area with a dimple to drill the smaller hole.

So I bought a piece of pine 2x4, just ordinary stuff. I'm trying to make a chair. I crosscut a part off to cut all my other pieces out. I laid out my cuts but when I tried to do the rip cut with a handsaw, the saw bound up really bad. I tried the coarsest saw, largest saw that I had, but couldn't get it to co-operate. I tried a circular saw with a shallow-depth first cut to reduce the amount of material removed, but that didn't help either.

So I look at the board and I notice that I have the center of the tree, and it must be the tension in the grain pulling the cut closed and binding the saw. Is there anything I can do to use this piece of timber? I've read that pine may be an outlier in terms of internal tension. Do I just need to look at the next piece of wood I buy and try to get one that is cut from a more outer part of the tree? Should I use a different wood? I've never had this problem before.

>>1371836
I don't think I'd use a forstner bit tough, it'd be a bit wide enough to fit the screw head inside, a normal sized screw, nothing too big

>>1364783
I have a piece of hardened steel (can't test, but probably RC 62 or so) that I need to drill three 1/4" holes in, but nothing will work. I have tried hss, titanium, cobalt, and masonry bits, but I can only get a small dent in the steel. Always well lubricated, and have tried pretty much all five of the speeds my drill press will go out of desperation after I tried the recommended one. I have also tried everything mentioned above with an 1/8" pilot drill as well. Do I need to buy carbide bits? I'm worried that my press isn't rigid enough for the carbide to not shatter.

>>1371859
Shouldn't really matter what order if you're using twist drills.

>>1371535
If you can find the batteries, they'll cost more than a modern drill kit, which would come with better batteries. Either rebuild the battery packs yourself, rebuild them with Li-ion cells and find a new way to charge them, or buy modern drills.
>>1371704
Twist on wire connector/wire nut. Sounds like what you had, just spend $5 on a big bag from the local hardware store and be set for life. Solder+wire nut is even better, but don't only solder, because if things go wrong, it'll melt easier and you'll get live wires moving around.
>>1371873
RC 62 is hit or miss even with just HSS. Titanium bits aren't really a thing you'll ever encounter, you're talking about some kind of TiN coating, which doesn't do shit other than keeping things like melty aluminum from sticking to the bit. It's not the bits that's the issue here, something else is amiss. How big of a hole, and how is it failing?

How do I make a fly window?

It's summer, it's retarded hot, but I'm not willing to open my windows until I have a fly window or I will hate myself for 2 months.

I've looked at my window and it's just a mess of bumps and odd shapes. Anyone have some plans or a walkthrough to make this easier for me? I don't wanna spend 40 bucks on a premade size adjustable plastic frame.

>>1372002
Do you care what it looks like?

>>1372014
To a small degree. It mostly has to be sturdy since I have cats and my window is rather big.

>>1371579
It's probably not traveling over 100 yards, so it's got to be something in your house. If you dont have anything new, then it might be something that you already had that is now breaking. An old tube style tv with a transformer that is going bad would be a good example.

Try turning on something with a speaker so you can hear the buzz, then walk around with it and see if the buzz gets louder anywhere. See if the buzz stops when you turn something off. It may take a while to find, but there is definitely something creating electronic noise somewhere in the house. The only way it's outside of the house is if it's something really powerful like a new radio or cell antenna that just got commissioned somewhere nearby.

>>1371908
The hole is 1/4" and it's failing because even after like fifteen minutes , the bits haven't really removed much metal. They were brand new, so I know that they were sharp still. They just seem to be "skipping" off the dent I already had instead of making chips like they should be. I've tried both pressing with a lot of force and not a lot, but can't get it to work still.

I'd really prefer not to ruin the temper then re-harden, because I would have to send it off for the HT.

Tape black plastic neatly over window. Pack insulation in it. Cover with plywood the color of your walls. You could always make it look like a framed painting or something. Cover in plexie and fake wood frame if u wanna go nuts. Should be pretty similar to walls then. A great improvement at least.

If you care 0 about loocks i would build a frame from floor to 1 foot above widow and 1 foot wider on both sides. Put a few layers of insulation till level with the wall and then put a few more layers in the wood frame. When 5th or 6th layer is in cover in osb and slide a couch against it. Works fantastic. I have done it

If the bits are wandering, have you punched a divot to start drilling in? And make sure the drill bit is at a perfect 90 degree angle to the metal.

Are reuseable furnace filters any good?
They cannot be worse than the normal ones, can they?

>>1372259
They were center punched and don't really have any walkout, I'm using a press and have verified the bits are square to the workpiece

>>1372449
Just dull bits then. Go slower and use more downward pressure.

>>1372449
>>1372471
Oh, and if you're not using split-point bits, get some. Regular bits have to push the metal out of the way in the center(that's why you pre-drill for bigger bits), split points don't have that problem. Alternately, pre-drill just big enough to get that chisel top on the normal bits to not contact the material.

Also I have feeling the ad is misleading, is it really the rolling toolbox and the top chest together for 700?

>>1372552
It's really both for that price. Specifications list 16 drawers, both have 8.

>>1372624
Thanks anon I checked the it again, and realize its for both. Should I go for that milwaukee or the harbor freight 56 inch? Both around the same price. I might end up going with Milwaukee.
