My slide valve and fittings arrived today
expect a semi auto or bolt action .22 rifle coming up, just about to go and PTFE the threads right now.

In that case be sure to watch the "almost finish" thread.

Yeah, i've read a lot of that.
Not sure whether to have bolt action or semi-auto now. I'm leaning towards bolt action for the ergonomics and aesthetics.

A little hybrid I threw together today, there'll probably be no testing until next weekend though

haha!
That looks like it could take a healthy bit of pressure
manometric or syringe fuelling? and how did you thread the spark plug?

I think it might be a CR10EK they are very close to 1/8npt thats what ill be using for my hybrid, I tested it on a little hybrid I made to 8x it was fine.

Hmmm... oh well, I'm not one to talk about unsafe fittings. In the circumstances I would probably be happy with slopping on some araldite and tightening it up

Yeah I put some hydraulic thread locker rated for 10,000psi, its just a tiny bit losers then a standard 1/8'' npt fitting. ill try make a smaller hybrid test it higher pressure.

The spark plug is the one crna described, I feel pretty confident in it because it bottoms out in the bushing and seals very well. The part that worries me pressure wise is the brass burst disk holder I made from garden hose to NPT adapters. Besides those concerns, expect some higher mix testing!

Ah well, if it fails, it will be towards the target anyway

Looks sturdier than the one I'm using on mine at the moment

I've held one of those before, they seem to be relatively lightweight, I don't think I'd use it over 5x but make sure you stand far far away <s>if</s> when you test higher

And how the hell would you know how powerful a 5x mix is? You haven't even made a hybrid that is made from proper materials!

HAHA
As much as I love busting GunFreak's balls about being a pneub, a pneub sufficient in hybrid knowledge can probably grasp an idea of how powerful a 5x hybrid mix would be. Though, I think GunFreak is wrong in this case and that the compression fitting could be used relatively safely at higher mixes than 5x. Then again; GF only expressed that he wouldn't personally use it above 5x and not that others shouldn't.
