I got a bigger tank! Right now I am only using 60 PSI out of 150 PSI, and it seems to be making a bigger impact.
One thing I am debating now is how to retract the glove once it is launched. I am thinking I can machine a small hole in the barrel that can wind back the projectile. Hopefully this hole doesn't reduce the punching power by too much!.
According to my rough calculation, I wneed 1000 PSI for a 1/2in diameter piston to have force that is equivalent to a human punch.
That's probably kind of dangerous, so I am going to test a 150 PSI tank instead. This will be four times stronger than my last tank. Should be coming tomorrow so I am excited to try it out!
Dust taped a PVC piston to my air compressor. Here is the result at 20ish PSI. The max PSI of tank is 45PSIish so I hope that is enough to really make the glove go flying!
