oh well ill try the pingpong ball thing

ok im 6ft tall but ill probobly just make a conon ball _fnord

do you know if they make these cause my barrel is 1.5inch and i would just grind the bearings down a bit with my wire brush grinder so ?

also how do i make a cheap bolt action i was going to just cut a hole in the end of the 1.5 INCH barrel and put a 1.5 INCH coupling with the edges removed from the inside

ok i get wat u mean thanks

now where would i put the valve on the bottom or on the top and wat should i use for 1.5" or 2" elbows?

im making another pnumatic co-axil canon and i was going to use this design and was wondering how to mod the valve for blowgun piloting?is it the same or do you have to do something else,or can you only do it with inlines
