i need help finishing my coaxal

[turner]

how would i put a 5/16 aluminum barrel sleeved in 9/32 inside the chamber. i tried drillling a hole in an end cap its to hard to make small enough barrel supports to fit inside.

If you glue the barrel support to the barrel and chamber, you will only need one support. So find a piece of plastic that will fit inside the chamber between the chamber and barrel and will make the barrel centered. Once you've done that, just glue the barrel to the support and then the support to the chamber.

For attaching the barrel and having it centered, just use a 3/4" x 1/4" reducer on the front of the gun. Screw in a 1/4" nipple. 5/16" brakeline fits pretty well in 1/4" nipples, so with lots of epoxy it should work fine.

i like noname"s idea but could i use like a 9/32nd compression fitting or something? i would like to e able to service it maby

You won't find a 9/32" compression fitting at a local hardware store; I can pretty much promise that. However, 5/16" ones are fairly available. The downside to those is (maybe just the brand Ace uses, I don't know) is that the little olive can slip sideways a little bit and bend the brakeline. It's happened to me before and it will make sealing quite difficult.
Another thing on sealing, if you just have a 9/32" brakeline barrel, it will cut a hole straight through your sealing face with no problem at all.

Remember the size is not the size of the hole. The size is the nominal pipe size.

i was going to put the sealing face on the breech of the barrel. for the barrel i got a 5/16 aluminum tube sleaved in 9/32 for the hobby shop. ace had a lot of stuff in 3/8 could i just wrap some tape on the section of the barrel? i kinda dont wana use epoxy because the walls are so thin to roughen up

todaw i went to lows and there selection sucks so i got a 1/2 to 1/4 reducer and jb welded the barrel see if it worked tomorrow
