hey, was having trouble finding a schrader with threads and was getting bored so i cut one off an old bike tube, sanded off all the rubber, and was left with this



just wondering if it would hold the pressure if i just epoxied it in

epoxy will work, alot of people have used that before.

but why did you sand off the rubber?? people use the rubber as a sort of washer type thing when they epoxy it in.

Get a small file and put some grooves into the stem before you epoxy it in.
Gives the epoxy something grip to.

thanks

ps. what does leaving the rubber on accomplish

Also make sure that you make a ring of epoxy around it on the inside of the chamber. Build up a supportive layer to form a sort of collar on the inside.

Try epoxying it into a threaded fitting. I've done that before with great success. just dont get epoxy on the threads.

Yeah do what mopherman said. And the rubber will hold much less pressure than the epoxy and would fail. Get a file and grind grooves just like bender said,

bender=novacastrian

yeah i'll try what mopherman said

and i got the bender thing, i like futurama too

This is the system I use for all my designs, I can confirm that it works and very well

Nice!Now I can finaly make 1/4 nipples swith schrader vlaves in them.

yeah, its a good way, iff you have a copper cannon you can solder that stem right into any copper/brass fitting just make sure to remove the guts first...or youl fry them

Out of curiosity, what type of epoxy are we talking about?

i was just talkin about regular epoxy, btw is the stuff that takes 60 minutes to set any different from the quickset stuff?

The slower Epoxy sets, the stronger it generally is. 24 hour stuff is the best. The quick set types that are a thicker paste can be hard to truly make a perfect seal.

yeah, but every epoxy has its purpose. The thick stuff is for something different.
