Delrin might be a good idea. UHMW stuff scares me. Too soft for me to machine.

I probably won't, but why ABS?

ABS (the solid-core variety) really is a superior cannon building plastic compared to PVC. It's more impact and temperature resistant. If you could get your hands on some pressure rated fittings you could make a much more durable valve.

But since you don't sell them anymore, why not focus on the Blue Flame IV or your next hybrid? :wink:

Hi Guys. I am trying to visualize the mauler valve variant. Does any one have a diagram of it? It sounds like what I am building, but I'm not sure if that's what you call it.

A mauler valve is pretty much like this valve http://www.spudfiles.com/forums/the-sta ... 10049.html
Except the mauler valve's piston is made out of a solid PVC rod machined on a metal lathe, with a built in check valve and machined parts that fit flush in the tee.

A barrel sealer will open faster in a smaller package, I don't see much merit in a chamber sealing Mauler. It would open slower or be bulkier and rely more heavily on the piston seals.
True. I wouldn't want to "rely" on o-ring seals if I couldn't make them (EX. in my garage with a dremel). I'm a CNC machinist (not operator). I'll make 'em all day. Can anyone tell how long a barrel seal with a washer can hold a charge?
