I'm looking for a step by step on building one, I've seen a really brief outline of it with the parts but no assembly instructions, I've built my basic sprinkler valve pneumatic and my advanced combustion I thought this was the next step.

For a piston I plan on using 1 1/4" end cap with a 1" or so piece glued in filled with epoxy and then a bolt going through with the neoprene gasket/washer on the end. I've heard this makes a good piston

I've tried search all I'm getting is nothing most likely due to my security on firefox ( no scripts allowed) So please don't say use the search button

Well you wont be able to build a mauler as that requires a lathe, but a normal 2" piston valve wont be too difficult.

Check out my how-to for this cannon:
