This recent burst trend inspired me to dig mine from over the summer back up and paint it. I used Krylon Fusion Camo in green and brown.

12" x 2" camber
36" x 3/4" barrel
3/4" union

Burst dics- white duct tape. Go at around 90 psi.

Beautiful, eh?

NICE! I like the paint job, what’s the make and model on the paint you used?
Once again nice gun, slicker than greased snot on ice!

2" x 3/4" bushing to a union. Burst disc goes inside the union.

*note to anyone who build one- Make sure that the part of the union that has the o-ring is attached to the chamber side. Otherwise, it won't seal right.

That is your average bushing.

The ones sold here aren't. Are you sure "Most are like that." I've never seen that kind before but I see and use another kind that are smooth often. The female sides look like a normal coupling except on the treaded sides there are
very slight bumps and on the male side it is just smooth.
