Do be carefull with the pressure testing Undy...

We lost my best friend's dad to a tank rupture some years back, a grenade couldn't have done worse. It was a Nitrogen tank with a fake test stamp (we think).

There's a lot of force in compressed air, a seat/guide machine I used some years back had a floating head jig that weighed around 100lbs. (minus the head) To float in on the machine deck it used 20psi of air. I couldn't believe it took so little pressure to do that.
