New test, but that the PAL is assembled and glued.
The barrel is made ​​of PVC-P with holes D14mm, covered with transparent polycarbonate.
The rupture disc is aluminum, 7 sheets total, approximately 0.2mm, I did in snitch because I've never used aluminum sheets ... too thick? not enough?

The noise was terrible, a gunshot!

very nice, look quite a bit different to the combustion, if you can put the disc in and fill with air until they burst then you will know if you need more.

Very cool! You immediately notice the moment that the disk bursts :)

So... 1.5x hybrid?

Thank
This is what I do to test my steel discs!
I think the thickness is correct because the combustion is complete when the disc breaks.

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 ...
