As hybrids aren't really my thing, thought I'd run this by the board first - any reason why this design shouldn't work? Any tips and advice appreciated

Looks good to me but wouldn't it be hard fueling it since its such a small chamber?

I suppose this will work well enough:

especially with a shrader valve. when you disconnect some air will leak out, messing with your mix. i don't know hybrids either, but i thought i would just point that out.

Hmm I guess. You would have to make an adapter wouldn't you?

Not in my case - I added o-rings to my shock pump so when you thread it onto the schrader, it doesn't actually open the stem, the air leaks in thanks to the pressure difference.

I was thinking of injecting through the barrel end just as you would with a combustion, closing it quickly with the burst disc then bringing it up to pressure with the schrader.

This isn't the first time I've tried something like this, here's a similar previous effort on spudtech, I just thought I'd give it another go.

what about a pure oxy mix, then he could just use a pressure gauge

Not too keen on using oxygen at this point.

it looks great jack
i love the spark gap means less hole sin your chamber
oh and making a adapter to the schradar valve shouldn't be hard.

good luck with it jack cant wait to see it

I calculate it'll take two epoxy "sessions" so a couple of days

This is a bit of cartridge test, I'm trying to get an idea of power levels to see if it's worth the expense of getting some machining work done professionally.

Hey,

I like your use of BRASS for a barrel. Finally someone saw the light Brass is as easy to machine and to braze as copper, it weighs a little less and it is much harder and stiffer.

Aluminum would be nice too, but there is the problem of joining it to other things; either you need fancy welding equipment, or you have to take chances with glue.

I always use brass for airsoft barrels but aluminium would actually be a better idea for the hypothetical cartridge body, a lighter cartridge will lessen stresses on the breech mechanism and be less likely to damage itself when it hits the ground. I don't believe I'd be "taking my chances" with glue, it's pretty strong stuff.

why not?

Probably because of the dangers of autoignition and/or detonation that they pose.

What mix will you take it to? And I like the way you use the schrader as part of the ignitor, ingenuity at work.
