Some objections:

- what's the screw for? If it's for filling, You could just do it through the burst disk holder.

- your spark gap is a little large, what mixes were you planning on going to and with what ignition source?




The screw is epoxied in place to fill up a hole, no further use.

I can easily adjust the spark gap. I'm using a lighter piëzo for ignition, and i'm aiming at mixes of 3x air-butane, and when i'm bored with it I will blow it up with 11x air-butane.
This thing isn't very strong, just 1.5 mm aluminium. It was a piece of bicycle pump tube. I took it to 16 bar several times. (and killed the pump internals with that pressure)

The thing is currently lying in my drawer, I have a leak to fix. I didn't have time for that, as I was heading for southern France :)

I'm going to have to get some masking tape skills to not get paint on my slide valve, I probably should've dyed the stuff before I put it on. Also, my main concern with painting right now is that it's hot enough outside to melt my polymorph :shock:

GF's correct, nothing special

when the epoxy has cured, it is leak free, and my bicycle pump proves to have a reliable manometer :D

I have an unlimited supply of rotten apples this time of year...

ITWOST I just hand pumped a 48cui tank to 3000psi, it really helps me value air efficiency when my arms feel like this :shock:

Hey Labtech, Who did you get the idea from? :lol: Nicely done, I still have yet to buy all the extra parts I need to finish the "Prototype" sitting in my garage.

Thanks!, but are you talking about the QDV, my mini hybrid, or my ignitor?:D

I got my mini hybrid leak free today, so I gave it a test.

JSR's design is approved!

At the 3x mix test it developed a leak, so I will have to fix that in order to do more testing, but so far i'm pretty happy with the results.

Fueling will only get easier with the size of my future project :D
