no you can't get clear sch 80 pipe that big to build a hybrid.
also if you could it would be like $200 for the chamber pipe alone

PS: learn to spell

I like the wooden mount, keeps things a little safer. I'm wondering how long it took to build? Are you putting the disk inbetween the barrel and chamber? Noisie beast aint it! NICE CANNON, I LIKE IT!!!! GREAT BUILD!!

You can get 4" sch 80 clear PVC on mcmaster. It's 140$ for a 4' chunk and only rated to 160 psi, which makes it unsuitable for a high-mix hybrid.

Nos hybrid Saftey

Unread postAuthor: mnrocketman » Fri Jul 28, 2006 7:35 pm

I did some calulations, and if you started with a 70 psi Nos-Propane mix, the final pressure would be close to 1000 psi. It would also be about 3000 degrees F. Plastic will not hold that kind of pressure (or temp), but metal will.

Yes, and the NOS would also detonate the mixture, which I doubt even the steel coud withhold without being deformed or even burst. We tend to discourage the use of oxidizers due to the hazards that they present.

I'm intrigued though, how do you calculate thos figures?

Actually, people have proven that pvc does show up in x-rays. There was a topic on here a while ago.

I did some basic chemistry to get those figures (PV=nRT). However, those calculations did not include the effect of detonation or efficiency, and that probably changes everything.

if i just put the barrel into the chamber and sealed it , then put the diaphragm in it,
would it work?

IS is true that hybryds are 2 as strong as pneumatic?
