[TheForge] A little OT -- a mini-scale saber saw?

[peter fels]

How much air do you need?
More storage means more air for longer.
Be very conservative with air pressure tanks!
They can go off like a bomb!..Lotta kinetic energy!
Putting them somewhere way over there, has a lot of virtue.

My first compressor was from an old refrigeration unit,
The tubing went to 2, 250 gallon, ( carefully washed out) former propane tanks.
I used several hot water heater over- pressure valves in each one and tapped a hole in the bottoms
for radiator drain valves .
Ordinary sched 40 house plumbing will generally deal with 100 PSI. if you are careful.

It was enough air to do a little sandblasting...or run an air tool for a while.
Needless to say, that rig took a long time to recover. 
Safe from air tool boredom.
Cost around $5 for fittings i couldn't scrounge.
