Penetrator MK.II

[foilboy]

Here's my shortened version of my previous cannon. I've reduced the chamber by a whole hell of a lot from 2" to 1" sch 80. The barrel is a cold steel blow gun barrel extension sleeved in 1"ID rubber tubing, sleeved in 1" sch 40 PVC. The QEV is a Fastenal 1/2". I used a schrader valve with a check valve in behind it so that I could fill the chamber with a bike pump. Works like a charm, and I can always swap out barrels for a longer one. Only thing left to do is to make a bracket to stabilize and reinforce the barrel and chamber.

That's some nice penetration you should think about getting a track pump and moving to the 200-250 psi range if your chamber can take it.
