thank you
For Thorjack, I would need a gun metal!
And 19mm internal, it is difficult to find ...

For ignition tests, I've done a lot, I have videos!

PMC- Multi chambers

I thought the concept of multi chambers to double the acceleration of the projectile, I do not know if this is true but hey I suggested the idea anyway ... I have not yet seen a PAL operating with this principle. So here is the pattern that speaks better than me! http://i45.servimg.com/u/f45/16/75/2...

Here is my test database, it delivers a shock of 300V and 420uF, it can load other external capacitor and I can use it to ignition two-and three-pin.
The circuit has an old cobra flash, that's why it loads fast.

To make a Mix1.5 or it will be more complicated because I put the fuel with a syringe fitted with a hose via the union.
The chamber is not obvious breakthrough of pressurize ...
