ABS Lining

[CS]

My next gun I plan on making a combustion with a chamber fan, interchangable barrels, propane injection and cap so you can shoot aersol sprays (if you run out of propane). I was planing on just using PVC to make the gun but I read on spudtech that you shouldnt use starting fluid or carb cleaner in PVC guns. So I thought if I made the chamber with PVC fittings and pipe then sleved the inside of the chamber with ABS I wouldnt have a problem with the fuel doing anything to the PVC pipe. But the problem Ive had with sleeving pipe is that it puts alot of stress on the pipe that it is inside of then on top of that your going to have an explosion in it. So I dont really know if is such a good idea know. Please sound off good or bad. Also if made 12 or so spudguns so dont treat me like I dont know what Im doing or talk like it.

You can use starting fluid, but not carb cleaner because it eats the PVC.

Your idea for sleeving with abs should work fine.

Although a can of propane will give you about a thousand shots depending and they are under 3 bucks a pop so you dont really need a cap if you run out of propane, because you probably wont run out of propane. Although im sure you already know this.
