Nice,
I was thinking about building from scratch.
The best design I have found so far is with the "vortex" block.
I have heard of using body filler for the block but i thought about milling it from 6061.
Most are using shop air for power but some are using larger co2 cylinders.
Theres a newer model strafer but i dont know if it uses the vortex block or a different design.
Any more input on the subject is appreciated.
