making threads with epoxy

[iknowmy3tables]

I'm now part of the school robotics team . Not nearly as great as spudgun building

anyways I was trying to mount a air cylinder on a special swivel ball and socket thingy but the threads on the cylinder are weird they are like almost like a common bolt type in the tap kit but like 1/16" off in size, I can't use a dye on the cylinder's threads because they might want to reuse it and with the same fittings.

so right now the cylinder's threads are held in a butchered socket of the swivel joint, I was wondering if i could try casing the threads with epoxy by first coating the cylinder threads with petroleum jelly or oil the pushing them into the socket with epoxy in it

It would probably be a better idea to use something like "thread repair compound" although even that might not be up to the tolerances you are looking for.
I would be a bit nervous that epoxy would be permanent unless you were very careful with greasing the threads very evenly and thoroughly.

Squidge some of that about the threads and when cooled and hardened it's pretty much like solid nylon. So it could easily be removed afterwards.

Absolutely a terrible idea however if there are any common thermoplastics that will come in contact with it while it's soft. It sticks to those like tar.

for some reason that made me laugh really hard, but i do agree with what you said, it just made me laugh and i don't know why

I've done this before to make the silencer for my CO2 AK, make sure all the contact areas are greased well, but not too much or the thread cast won't be deep enough:

You could also just polish the threads to be epoxied, it will give a tighter fit but still come apart. Basically, in my experiences, epoxy can be removed from almost all "fine" surfaces with a little scraping,as long as the surfaces are of a non-porous, metallic nature

thanks guys I've been busy for the past few days I think I'll give it a shot now
