If its oil you might be able to sand it out and re-coat, if its varnish... sand it all out and start again.

So CTE is blowing up. Everybody knows about it now, and ok, now we can do something about it. These people are losing their minds, and it's time to come up with a remedy.

What causes brain trauma? The brains inability to cope with outside forces due to the design of the brain/skull. How do we solve this? By creating something that can reduce the force of the...outside force. How do we soften the blow?

Maybe if I was a chemist I could come up with a drug that wouldn't allow this devil protein to take over the brain, but I'm not, so I've come...

Avoid the time and door locking required for conventional self-clean ovens. Steam Clean allows for quick cleaning of minor food spills at temperatures lower than the standard self-clean feature. Simply pour 1 cup of water into the bottom of a cool oven. Close the door and select Steam Clean. The cycle lasts about 30 minutes, and loosens and softens the grime in the oven. Once the cycle is complete, wipe out the moisture and food soils with a soft cloth. Because Steam Clean uses a lower temperature, the oven door does...

It would help if you had said what country/area you were in.

I am in the USA, and get cheap optics from Surplus Shed. They have a website and sell surplus items of all kinds but mostly optics and vintage camera stuff.

If I want *good* optics, there is Edmund Optics,,, but bring a credit card, because they aint cheap. A "cheap" 25mm simple lens can cost $50, and a higher-grade one the same size with a good AR coating can cost $125 or more.

While messing around with the new tail light setup I put on my car, I broke this little ground tab off. What's the best way to reattach it while still maintaining a good electrical connection? I tried superglue, but that didn't hold. Is there some sort of epoxy that would work well for this?

How was it attached before?

They make conductive glues but that's not the method I'd use. I would prefer to use a screw going through that eyelet into whatever it needs to ground to. Or solder if I absolutely had to. Can you get a pic of the other side of the assembly?

Wait...is that tab even attached to a wire? Does it just provide a bridge from one surface to the other?
>>
>>1020237
>>1020239
Don't have any other pictures of it at the moment. The tab was attached by what looked like 2 very small solder points. The part that I'm pinching between my fingers is I guess the male part of it. I crimped a female connector onto the wire that I used for the ground, and that's what is used to make the connection.

Hey /diy/,

I want to use an old scissor jack to make a rudimentary press. I have some scrap ~1.5" diameter, 1/8" thick steel pipe that I'll be welding into a rectangle to make the frame.

What I'm not sure about is how to fit the sides for maximum strength. Should I use saddle joints in tension (1) or shear (2), or should I just miter the corners (3)? If it makes any difference I'd be using a harbor freight flux cored wire machine. Thanks for any advice.

>>1020030
First thing to do would be to determine the pressure your press would see. Then determine a safety factor for design and see if the surface area of your schedule 20 our whatever pipe would sufficiently withstand that pressure. To calculate this you would determine the total cross section area of the pipe wall and the tensile stress of the material if known. If not known you could just use 40k for carbon steel.
>>
>>1020030
Also I would go with the saddle style fit-up just as a personal preference. You may also look at attaching strong back to the press to prevent deflection vertically of needed. Not sure still what pressure you would be looking at. I successful made a press/punch out of some scrap I-beam years ago and successfully punched 13/16" hole through 3/16 plate. This was powered by a bottle jack. Good luck.
>>
>>1020052
The jack is only rated for 1000kg, so I don't think safety is too big of an issue here.

>>1020054
I'm leaning towards the saddle joints, too. But would you do option #1 or #2? My guess is that 1 is stronger, but maybe counter intuitively, #2 is?

I wouldn't mind stuffing foam on my side because I don't need the ducts to blow heat or air because like I said I have a separate unit from the entire house that doesn't use the duct work.

Would shoving foam up my side be any cause for concern, I mean is it safe to do so? Could certain materials present a fire hazard being in the duct during winter when the heat will be blasting?

Depends on the quality of the mask.

This is also a classic point of contention between old and newschool welders.

I think it would help for sure, but a welding mask is designed to protect your eyes from a blinding light the size of maybe a golfball and I would imagine the flash from a flash bang is a whole lot bigger?

You'll want a cheap pan scrubber, the scrubby side you use when washing dishes and a pot I'd citric acid crystals, like £5 for a kilo on eBay/Amazon etc.

Scrub the loose rust, submerge in warm water with a spoon full of citric acid. Wait an hour, scrub again, rinse, repeat until it's shiny clean. This is the most gentle way I know.

Warning: when you remove the meal from the water it will start visibly rusting again within 30 seconds. So either submerge again after rinsing it dry immediately....

>Will large hooks drilled into the wall fuck up my studs or something when we both go in it?
Yes. Studs aren't made to take large lateral loads like that. With big enough hooks, it might not pull out immediately, but I'm guessing you don't want to use the hammock like it's made of eggshells.

So here's what you do: You make an independent frame to hold the hammock, one that's actually made to resist the forces involved. See pic related for a nicer...

i would advise against it, if you're talking normal white glue. because it wont be strong enough.

Quick drying JB Weld would speed things up and it's paintable. The one with the yellow/black tubes. But to be honest my first impressions of what you posted even from the home page thumbnail was that it doesn't look good, it looks tacky. Like some shitty art piece a student did so they had to hang it up for a few months in a school because muh creativity then promptly threw it away. Not trying to be a dick, just want to give you a heads up that if you spend all that time on this it won't look good to most people. There's a reason you don't see this design anywhere, sorry bro :-/ Kudos for trying to be creative tho

Sup /diy/

One of the screws holding my glasses together, by the end piece, keeps coming loose. I'm assuming I could use loctite or some other thread-locking product to stop this from happening, but I don't have any on hand, and I kind of doubt I'll be needing it in quantity anytime soon. Plus I'm kind of broke.

Any cheap-ass substitutions? Superglue, nail varnish, whatever?

if the frames are all metal, superglue. If you ever need to remove the screw for any reason, acetone will dissolve superglue easily.
>>
>>1019547
It's all metal. Should the superglue be applied while the screw is tightly screwed in, or should I loosen it a bit, apply the glue, then tighten?
>>
using glue in a situation like this, where the area is so small, is hopeless. a paper clip, bent into a loop will last forever. tho it'll get rusty after a few years, so you'll have to replace it. i got some thin stainless steel hobby wire, for making bracelets and such, and it's lasted over 4 years looking good as new.

Most soaps/detergents are usually non-volatile, so probably not. It it's urgent to recover the leavings, I'd say centrifuge the goo (or just carefully decant as best you can after the bucket has settled).

unclog drain.
Plunge first, that may do it (get a sink plunger).
If that doesn't work, then I would suggest a snake rather than a chemical, but that's just me.

I have a dishwasher that does the same thing: when it flushes out all the water, the sink it's connected to backs up for 20 seconds or so.
It still goes down tho, because my drain isn't clogged.

You used the correct connection, I assume? Basically an upside down "Y"? If so, like anon said, snake out the drain, or check the p-trap and replace/clean if blocked.

was it working before? was it already clogged? if so for how long?

snake is the way to go
