Sup /diy/,

Here's the problem. My kitchen and bathroom sing share the same drain pipe BUT. The bathroom one occasionally belches the most horrible swamp odour whilst the kitchen one doesn't, ever. They're connected! If I "blow" into one of them it comes up out of the other one.

Why does it smell, and why only the bathroom one? Pic related, a highly professional illustration of my flat setup

>> No.1150251

Your plumbing vent and/or P-trap in your bathroom are fucked up or non-existent. If you can look at your sink drain does it come to a "u" shaped bend right after the sink? If it does is it shallower than the kitchen sink "u" shape? Does this stink problem arise when you flush the bathroom toilet and does the toilet have trouble flushing?

>> No.1150254

it has a functional siphon at (almost) the same height as the kitchen one, this is a recent problem.
The toilet flushes perfectly and has no influence on the problem. sometimes when I come home the shit just fucking stinks

>> No.1150257

Have a plumber snake your toilet, or the closest clean out. If it still does what it has been doing you need to have a camera inspection. If your drainage pipe is busted and underground your home owners insurance should cover the cost of repair.

So, been working robotic welding recently, and I have noticed that I do a lot of grinding, more than usual.

I use my electric corded and cordless grinder, but of course they wear out over time, due to the brushes.

Was thinking, is it worth getting a air angle grinder?
Does anyone have experience with them? I asked around my shop, and no - one has ever used a 4" angle grinder.

Hey /diy/ first time on this channel.
Basically, I've got this ring that has an enamel/something filler in the engravings on it that makes the engravings black. I'd like to remove this substance and have had some luck on the sides of the ring by scrubbing with a coarse dishwashing sponge. I'm wondering if there's an easier way to remove this filler altogether. Thanks!

Hey dudes, I'm making a deadlift platform and I was wondering which of these two "designs" would work best. The main goal is to dampen sound but my gym is in the basement with concrete floor so I'd also like to minimise vibrations.
Please note that the sketches are in no way to scale and yes, there will be a thing in the middle to stand on.

In practical terms, it's not going to make a huge difference, I think.

In theoretical terms, the alternating stack would be better.

Deadening sound is basically just a game of 'how much mass can I have supported by a damping material". The more mass you have and the more "loose" or de-coupled it is, the better.

But at the same time, in this case, you also want to decelerate the weights you're dropping on them as gradually as possible, which the second will be better at due to the increased thickness of the matting on top. Either way you do it, adding some thick foam padding (like those interlocking "puzzle-piece" foam floor pads) will help greatly for this reason.

>> No.1150234

Thanks man. The reasoning behing the alternating stacks was that the plywood piece in between the rubber was going to spread the impact over a greater area, allowing more of the bottom rubber sheet to absorb the force.

I've thought about using foam puzzle pads or carpet padding but I'm worried it will budge under the weight giving me an uneven surface

>> No.1150249

>under the weight
How much weight for 1RM?

>> No.1150256

Been there, done that.

Your solution is horse stable mats. For example:

You can get ones that are close to an inch thick and they are usually cheaper than ones they sell specifically for gyms.

The noise problem wont be reduced because it is mostly produced by the movement of the bar + plates

>> No.1150259


You're worried about bulges when somehow you plan on deadlifting off of 2 tall stacks of wood and rubber. You sir are retarded. You start with the weight level with your feet FFS

Basically, I went to the dump and picked up this lovely old TV, a Binatone Starvision 12" from 1978.

Since the government sold all the UHF wavelengths to the phone companies, I had the idea of making some device that would take the digital free-view channels coming from my satellite, convert them to various analogue signals, and send them to the television through the input in the pic.

Now I don't know if this is possible, but what would be cool is if I could construct a device that would transmit multiple channels to the television simultaneously so that I could use the dial to tune into them instead of changing channels digitally.

Would appreciate any advice, speculations, abuse, and wisdom that you guys/gals can give.

What you are looking for is a UHF modulator - video in, UHF out - CCTV Cos and people still sell them. eBay, etc. Alternatively, find an old VHS video recorder with a video in - they output UHF on a specific channel, if it has a 'test' switch, that will output black bars, hunt for them via TV tuner.

Your problem with all of this, you (usually) only gonna get composite video in - you want HDMI or some shit, you gonna have to convert that signal somehow as well.

>> No.1150255

If you want to covert multiple channels you will need multiple receivers and multiple RF modulators. Better to just covert one in your case and change the input to it. +1 for old VCR.

I got a problematic ltz400. New plug, clean carb, clean air filter, valve lash within spec, 110 psi compression cold. It will start and run with very high idle,when you drop the idle engine dies(via throttle cable) starts back up when you adjust throttle cable again, pretty sure choke is shot but after its warm I should be able to get it to idle normally, it doesn't. Also it will rev without issue when you hit the throttle. Any ideas what I'm missing?

collect apricot seeds during the right season, the amygdalin content varies though the year and can be as high as 5% of the dry weight of the seed.
It is probably advantagenous to break the husk with a nut cracker, a plier, etc. and cut the softer inner material to smaller pieces.
Extraction of amygdalin can be performed by

Immersing the material in methanol and subsequent ultrasonification.
Soxhlet extraction with methanol
Reflux extraction in water in the presence of citric acid.

Removal of the solvent in vacuum will yield a crude material with significant amounts of amygdalin.

Mix the liquid with ammonia and paint thinner, in tupperware and come back after 2 minutes, and you should have a whole tray of a bathbomb, cut round shapes out of the tray and viola you now can use it safely.
Then sniff the mixture afterwards to be met with a nice rosy smell.

It really depends on the reflector size and shape as well as the bulb temperature.

That IKEA lamps has a very large reflector which helps make the light really even when turned upside down. I use a 1000 lumen 2700 K LED bulbd from ikea with it. Even with the dimmer on the lowest setting, it perfectly lights up my 12ftx12ft room.

Grab some glue and a needle. Use the needle to inject glue through the fabric. Then just push it up to the ceiling. As for the smoke smell. Trust me, there is nothing you can do about it.

Mostly agree -- land is much more highly variable in cost than the building you put on it. However, building prices do vary from place to place -- union labor, local labor shortages, and local building/zoning/code/general fucking with the contractor laws can all drive building prices up.
