It wouldnt hurt to up your bumper a little bit though. Good luck with it. Have you seen my asco launcher? The power is unreal! I put a golfball through both sides of a steel drum!!!

My piston was light, but it exploded... so... But no, I have not seen it.

matty do you have a youtube page with videos of you using your cannons?

There seems to be an epidemic of Mauler back plugs cracking at the screw holes. Other than Evan, you're the only person to mention this, Matty, but it still concerns me a lot.

It looks like it's time to revisit the drawing board for yet another Mauler design adjustment!

@ spuddestruction no I dont, only camera I have is on my cell. I have a few damage pics posted in the forum somewheres but nothing that hasnt been done before. I have a few pics of a 55 gallon steel drum I put a golf ball through that I need to post. @ gort the back plug itself cracked not the tee itself, however that happened to the supah valve though

Which is why no one likes Supah valves.

Make it out of metal. Aluminum piston, steel TEE, steel cap, and .5 inch thick rubber bumper. For use at 400 PSI.

Noone meaning you??? Its made from pvc so its going to break sooner or later. Dont rag on it till you try one. Its a well designed valve just like the mauler except its a chamber sealer. If you had one or tried one you would love it. I have never heard a bad thing about one. You need to try a diaphragm dust collector valve if you wanna see power!!

I have a 3/4 inch 400 PSI QEV shotgun. It's actually for sale. It's quite powerful. But Gort and I have also discussed making a chamber-sealing version of the Mauler. But PVC should not wear down that easily, that's why they use it to build houses.

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.

Also, PVC isn't used to "build" houses. Siding and plumbing are made of PVC but that's about it.

I have been framing houses for 15 years and I have never use pvc to build a house. it's made to use for the plumbing yes inside of walls and underground never to be seen or disturbed. Its not made for what we use it for which is why after time it breaks. Vinyl siding is used to side houses.

Whoops.. I meant to say plumbing and water delivery systems. And it was just a discussion of theory, I had the same argument about faster opening times, and so did Sean. One thing we did discuss is a hybrid version of the Mauler, made out of steel, and aluminum.

That would be sweet. A supah mauler!!!!

The metal sounds cool, but my shop is set up for very little metal work, and I hardly have the experience with it.

Chamber sealing Mauler, kinda neat idea, but I'm not sure there would be any practical reason for it.

As for correcting the stress problems on the back plug, I think all that's needed is a thicker bumper. Possibly just a different material. I'll look into it after this weekend.

Have you considered Delrin or UHMW polyethylene?

dude, i never laughed so hard from that, thats funny, i hope no one builds a house using pvc lol

Hey gort,

For a bumper, I use soft silicon rubber cast into a kind of a 'rubber-stopper-with-a-hole-in-it' shape for simple pneumatics. I've put at least a couple hundred shots through my little 1" porting cannon with no issues.

How much would it cost to bulk order pressure-rated ABS versus PVC fittings? is it actually possible without raising the price significantly?

I thought vinyl siding was just PVC with a different plastisizer added, to make it impact resistant rather than ridged. you could have been using it all along...
