It may be mentioned somewhere in the vast expanses of this thread, but what are you using as a sealing face for the burst discs, and how well does it withstand repeated firings?

Do you mean to say that the sealing face is brass? It must be quite finely machined then, and the disc would need a very smooth surface.

the surface is made of brass, I put on this surface rupture disc and a steel flat seal rubber made of 20x27mm on this disc.

Nice family photo :)

I will try and post you the projectile soon, if not tomorrow I will do it on Monday.

Since I'm probably going to get started on the "long range" projectiles soon, can you confirm that the barrel inner diameter will be 33mm?

I look forward to keep it in hand!


I can easily have 30mm copper tube inside the 33mm I have to order it online ...
Length it is necessary?

1 metre is more than enough :) I'll see if I can get started on the first projectile tonight, it will probably look like a bit of a Ryanair mini-boy :D
