Sleeving question

[zeigs spud]

i'm going to sleeve my 3'" wide barrel. the only prob i got is that idk how much i should cut out, wht to use...(hack saw isn't strait a line enough is it?) and i know it's a pain to get the sleeve into the barrel so once its in there how do i fill the small gap inbetween? i've seen that people put straitend coat hangers into it but dow i do putty it up to stay in and be smooth?

hey this is paul(i hope this is alex im talking to, if not forhet what im saying) i think u should use a mider box to cut the pipe or make a jig. and u should definatly try to fill the gap before putting it in the barrel. ..... and i havent built a neumatic yet so i might be wrong but ill talk to you when i start it.

ok sry i just thought of a good idea (but again i have not done it before) ..ok if a table saw is not available u could make a large jig with 2x4s but it would have to be precise. and if ur trying to sleeve it down for tennis balls theres a pvc and sprinkler parts outlet downtown that sells 2.5" sch40 and 80. this works very well for tennis balls .....just an idea aim me if you want more info

The small gap?
Try hardening foam.
It comes in can, try to find it at home depot/lowes in insulation.
