Sleeving issue

Unread postAuthor: DinerKid » Wed Jul 15, 2009 1:21 pm

hi i have a slight sleeving issue.

i currently have a 3/4" conduit barrel on my paintball cannon. i am noticing that about 20% of the shots curve a ton and i am guessing it is caused by the shot spinning due to contact with only one side of the barrel. i was told that i could sleeve pretty easily a piece of .5" sdr 13.5 into the current barrel to snug it up a bit on the paint ball. after looking for this in a hardware store (Home depot) i found nothing. then i looked online and found some specs and it appears that the OD of the .5" sdr 13.5 is about .84" while i measured with a caliper the ID of my conduit barrel to be .81". however when i looked up the spec it came out to be an ID of .86". so i am now left with two questions

1- can .5" sdr 13.5 be sleeved into .75" conduit with no or minimal sanding?

2- were is the best place to find .5" sdr 13.5?
