Help with leaking joint!

[hi]

you get JB weld at any hardware store. It comes in two litle tubes and you mix it together.

and JB Weld IS epoxy. it has epoxy resin, which makes it epoxy.

you can get jb weld at the hardware store. i like to mix up some soapy water with food coloring in it to spray on all joints to check for leaks. just look for bubbles blowing. no bubbling no leaks.

Tried it out today.... epoxy lessend but did not stop the leak. put on a second coat as a last ditch try to not have to re-build 3/4 of the gun. true pity that i build an extremely functional piston valve only to have the cannon brought down by a stupid leaking joint.....

OK see how much of the epoxy you can get off easily. Mix more epoxy, JB Weld is good stuff, and see if you can't jam it into the joint a little with a toothpick or something, just get it up in there. Then slather a bunche all around the joint thickly. Put a strip of duct tape around it making sure you don't push the epoxy out of place. Then wrap another piece of tape tighter, then another tighter. The idea is to put pressure on the epoxy to get it into the cracks without pushing it all to one side.

Im probably just going to have to redo the front end of the gun.... oh well il lose about 1 inch of total chamber/barrel length. it could be worse... a lot worse.
