No. The threads in your picture look to be 1/4 NPT and would work best with 1/4 ID hose. You'll need a 1/4 female connector as well.

>would work best with 1/4 ID hose.

I was under the impression that most air tools and equipment have the same size connectors (with some different profiles for auto vs. industrial, etc.), but that for something like an impact wrench, a larger hose (like 3/8) hose would work better than a 1/4 hose due to less restriction, but for something like a nail gun where you drag the hose all over a construction site it's easier to use the smaller 1/4 hose since the gun still works ok being as how it just fires a quick blast.

I'm building a fence. I want to use 2 by 4's for the rails but the short side (1.5") facing the boards. My posts are 6.5ft max apart. About 15 pickets between posts. 3.5 inch width pickets with 1 inch air gap, pickets only on one side. 5ft fence height, 2 rails between posts.

Should I be worried about it sagging or will it be strong enough? Brown Pressure treated pine is the wood. I'm doing this because I think it looks nicer and the screws I bought are too long if I orientate the 2 by 4's the other way. I think it would be OK, but I can't find the numbers to do the math.

I'm restoring an old Rockwell drill that I found at a thrift store. I've gotten it taken apart except the main housing that holds the motor, the rotor looks like it was pressed into the rear of the housing. pic related, I circled a small hole beside the bearing where a rubber plug was in place. I have a feeling that hole is meant to be used to pry the bearing out but I can't fit anything in there.

There are no drawings online that I know of and with every other drill restoration I've read/watched, the rotor just falls out with a bit of wiggling or there's a hole on the back where it can be tapped out using a hammer and punch.

Well this is the exact opposite of me.
I used several containers of it to strip paint off of bike frames. AKA, cover the bike in goop and throw saran wrap on it and wait.

Its gotten on my bare skin and I havent had an issue with it. It discolored my gloves but didnt eat through it or anything.

The fact that just being near regular stripper is like breathing fire is enough for me to never use it.

Question about bearings:

I'm replacing two bearings on a pool pump, 6203DW and 6203DG. My limited understanding is that the suffix pertains to the seal and/or lubricant used in the bearing.

Just curious, what CNC based cutting/machining process provides the thinnest kerf?

Fiber lasers get about .005", EDM is good down to .002 with the right wire on thin materials. Are there more precise EDM machines capable of thinner kerf? Is there another machining process I am unaware of that is capable of thinner kerf?

I am aware shearing provides virtually no kerf, but I'm disregarding it due to the deformation of material.

Pic kind of related. The little stars are ~.040" dia out of 11ga stainless, cut with a 10kw fiber laser.

I took it apart and the motherboard seems okay and the battery still has voltage, also the console is still charging (checked with a multimeter).

I want to stop this rust without caring too much about what the end result looks like (old car). Is there a spray or liquid I can apply to convert and stop the rust that is commonly available and that I can buy from a store?

I live in Ontario, Canada and google told me something called Corroseal was decent but I can't source it locally. Any other more commonly available brands good? Any recommendations?

ie I'm hoping its a rust converter + primer AIO. My plan would be:
>Sand/grind the affected area
>Clean it with some lightly soapy water + clay bar to try and get any weird contaminants out
>Apply rust fixer + primer coat as required and let it cure
>Paint over it with touch up paint and a few layers of clear coat on top

Just need some help finding the rust primer thing.

>> No.1613055


Because CO2 doesn't liquefy (with the associated change in density) until at least 800PSI or so at room temperature, and higher when it's hot. Naturally, the can would have to be much bigger, heavier, and more expensive in order to contain that kind of pressure safely.

Hence, various hydrocarbon derivatives that have much more reasonable vapor pressures.

usually a pressure relief closes automatically once pressures drop below cracking pressure. so the closing pressure would definitely be lower than the opening pressure? or no

So you know PEMDAS maybe? Well it's a half-truth and I think it's not explained well by teachers.

Addition and subtraction are the same operation. I find it easier to think of it as addition. When you think you are subtracting, you are actually adding a negative number.

Multiplication and division are also exactly the same operation. If you have a+a that's 2*a

Exponentiation and rooting are also the same operation. If you have a*a that's a^2

Did you know theres an operation for repeated exponentiation? Tetration

Parenthesis are just organizers to make things simple to write

You can multiply by 3 or 5 and divide by 2 or 4 and get somewhere in your equation. You can also multiply by any n/n fraction, but that's only useful when adding and subtracting.

Look at the side with x. That's an unknown 4*x/5. Or 4x/5 or 4/5*x they are all the same.--Note that 4/(5x) would not be the same that would be 4/5/x.

So 4/5x and if we divide by 4 and multiply by 5 that would turn into 4/4*5/5*x or 1*1*x which can be written as just x. That's nice, that isolates x so I can get x=something.

Let's go back to the equation and do both sides so they remain equal to each other.
2/3=4/5*x multiply both sides by (5/4)

Trap for young players is to not multiply the entire equation by whatever you are using to simplify. So if you had 1 + 2/3=4/5*a you would still multiplay by 5/4 but. Ow you have
5/4*1 + 5/6 = x
Sometimes you could leave it at that or plug it into a calculator for a decimal answer.

But simplifying more
5/2/2 + 5/2/3 = x

We need those to have identical divisions to add them together. We can pull 1s out of nowhere because they are always there. And what is 2/2? 1.
5/2/3 needs another 2. You can write it as 5*2/2/2/3 without changing its value at all so you can do that without applying it to the rest of the equation.

>> No.1613317

So now
5/2/2 + 5*2/2/2/3
Left side still needs a /3 and we can only get there by multiplying by 3/3.

So now we got
5*3/3/2/2 + 5*2/2/2/3

/3/2/2 is exactly the same as /2/2/3 so we are good
(5*3+5*2)/2/2/3 = x

We could factor a 5 out but it doesnt really simplify anything.
15+10 =25 /2/2/3 = /12
25/12 = x

But can you melt old solder with a lighter? Or atleast soften it?
For some reason I suspect that from years of leaving my TV on for hours has loosened the RF cable connector.
>Pic related.
You can kinda see it's not connected fully so it might be giving me really bad signal.
All I did was bump the RF cable and it's been acting funny since. Pretty sure the cables fine so I think it's the TV connector. What do you think?

>do I need to suck it up and go through the more extensive repair method?
If the 'plug' is reasonably solid and takes some pressure to move in, you don't even need the kit.
mix enough plaster of paris to fill the dent 1/3 - 1/2 half way.
don't try to fill it all at once!
plaster dries pretty quickly so you should be able to apply a second layer in a few hours.
don't fill to the top on the second layer either
after the second layer dries, use a sharp knife to bevel the edge of the hole - you're trying to remove any paper edge that could 'stick up'
the red line is where to trim the paper
you may be able to take a shortcut on the blue line if the paper is still level above it
if the plaster is within 1/8" of level with the wall, finish filling with drywall 'mud'
this fill needs to dry overnight
once dry, sand smooth and flat with the wall and finish with a 'skim coat' of thinned drywall mud.
once it's dry you can try to get the same texture if there is any
from the pic, it looks like the paint was applied directly to the drywall with no texture coat
once it looks good, paint to match.

If you look at my pic you can see they just applied a big glob of it on
Is that really solder or could it be something else?

>Friction fit
Yeah. If you zoom in you can see its not fitted properly at all. That's why I thought I could loosen the solder and reconnect/fit it properly.
For some reason I think from prolonged use the solder has been softening and then gravity decided to slowly pull it down and loosen it.

That's not how solder works.
It 'freezes' (becomes a solid) at not much below it's melting point.
It would have to heat to at or near the melting point again to 'soften'.

>It's more likely the center pin of the RCA connector has corrosion or the center pin of the RF connector is broken off. Did you look?
I tried looking inside with a light and all. It's alil awkward but from my eyes it looks like the point is too far back. Looks like there is a copper wire just like on the coaxial that's suppose to plug in.
I can see it but I can't tell if it's broke. But it does look like it's too far back to be even making contact with anything.
I'm getting picture on the TV it's just got lines and fuzzes out intermittently. Not to mention the hum that's coming from it. Also the moment the picture has to show dark colours the screen really fucks out and turns white. Seems whatever signal for black really fucks with it.
Sorry. I just thought because I remember the PS3 having an issue where the soldering came loose after awhile that caused the infamous red/yellow light of death. Just like the Xbox.

Yeah the “plug” is fairly solid. It’s a little weaker on the bottom section where it expands to the left a bit. Is there a best way to apply the plaster when you’re trying to partially fill in a small space? Does a brush work or do you still use the same wide spreading thing you see in most repair videos?

>> No.1614903

>Does a brush work or do you still use the same wide spreading thing you see in most repair videos?
for that size hole a tongue depressor or a 1" putty knife or anything similar
the first layer being rough is not a bad thing - gives the second fill something to hold to
the second coat is similar but make sure none of the peaks get above the level of the hole
You don't need the wide blade until you get to the final two coats - the mud fill and the skim coat.
It's much easier if the wide blade is wide enough to reach all the way across the hole.
That way the un-damaged wall guides the depth.

There is no way to "convert" the rust back into original metal. It's best to take the rust off (A brass brush works fine for this, a scrubbing pad, whatever) and then in the case of a car treat it just how you would if you were repainting it.

Most things that advertise themselves similar to that "rust fixer" are just things that disallow moisture from getting to whatever surface was rusting in the first place, usually by coating them with something like plastic or sometimes a layer of copper.

(caveat: Technically you can convert rust but 99.999 percent of the time that's not what people mean at all when talking about cars, nor is it what products mean when they advertise that they convert rust. In layman's terms, it's not a thing.)

If the ground wire is not conducting current, it's just there as a shield to protect very low level signals (like from a microphone) from interference from external sources.

If the microphone wires are twisted or use other protection, the shield may not be needed.
