Hey /diy/ I'm trying to machine a shot glass out of 20mm

>>1032239
It's a great idea, use something called bisphenol a to cote it. It's the same stuff they coat aluminum cans and canned foods with.

>>Will alcohol affect the metal
No, the casing is brass. A couple washes with soapy water and alcohol will get rid of any lead/combustion residues still lurking around. Pretty much any cleaner that doesn't have ammonia will do.
>>Is there a coating, resistant to alcohol, that I can use on it
Something that isnt't water- or ethanol- soluble. Only thing I can think of off the top of my head is teflon, but that shits too complicated to coat with at home. Just make sure whatever you use, you seal the bottom where the primer comes thru
>>Is this even a good idea?

go get turnt my fegit

You could place a glass shot glass inside it, that way you get the look and it's safe to use.

>>1032239
pickle the brass first to get any lead out. then seal it. i just googled food safe metal coating and a bunch of shit popped up. lrn2goog

Hah cool. How much booze does it hold?

My 2c would be epoxy resin poured in thin to seal the primer and let the brass taste reign

Not a bad idea. Or a test tube.

It's a valid question considering how AFAIK, they use mercury in the primers.

>>1032496
Why did you even make a post?

>>1032506
Not noticing small details are what get you injured or killed in life.

>>1032527
Or make life not worth living cause your too busy worrying about shit that don't matter...

>>1032506
Well I thought it was funny

>>1032296
that is a shitty as fuck design, so cluttered and hard to understand at a glance.

and a Gibson certainly does not use sett vermouth.

>mercury in the primers
Nope, the primer is lead styphnate / azide. Cleaning will suffice.
If you care for any traces of lead, you may try an non-oxidizing acid (e.g., hydrochloric), copper will resist that, lead should dissolve.

>Is this even a good idea?
Are you able to keep it clean? In particular the room where primer was, it may be a pain in the ass to clean that.

>>1032239
You could tin the inside. Food safe.

Brass is a really dirty metal you don't want to be drinking out of. So if you can line it properly fine.

>>1032239
Lead melts with the heat of a lighter op.

Turn it up and torch it!
Then maybe some mineral spirits

Then maybe some soap.
Then use a simple copper-pipe cutter.

And there you go.
Shot glass

Damn, I didn't think I'd find a high res image of that poster here of all places.

Thanks anon.

It's fine. Stupid, but fine.

1: Put it in a vigorous boil for 7-10 minutes. This should remove most carbon deposits inside the case.
2: Knock out the primer, reboil.
3: Soak in pickling vinegar (18% acetic acid) for 72 hours, this will dissolve any lead remaining.
4: Reboil to remove all traces of the vinegar
5: Fill the primer pocket with silver-tin solder to make it watertight
6: Enjoy. No need to line it, brass is a food-safe metal.

>Forgetting about the 30% zinc in C260

Line it. The rest of this guy's advise is ok, but line that shit.

Don't do >>1032252. Bisphenols are endocrine disruptors.
