Yes, regulators have 1/4" femele thread.

Because mapp gas costs 8 bucks for one tank and propane is only 3 bucks.

It's like in a combustion gun...the pressure is created by heat from a combustion....if you use sugar + KNO3 to generate pressure, the pressure will rise for a few seconds and then come back to atmospheric pressure.

I use metered propane and it works fine 8)

You should make a barrel support. The barrel looks a bit crooked.

92.62 $

Regulation pool balls are 2 1/4" in diameter so the barrel might need sleaving. If a regular pool ball have a diameter of 2 1/4" , 2.5" sch80 pvc pipe might be the best. Following McMaster chart the ID of 2.5" sch80 is 2.290". So there will be a 0.04 gap and mcmaster sell it only 18,36$ for 5' :D P...

You will need a male adapter to glue on the pvc pipe and screw the other end in the ball valve ( if the vall is threaded).

I think it's a "big" minipump that work exactly like clide's one
