I had thought about posting this before - it's the RT blanking system
thread that made me do it. This is an online school:
Abrasives, CNC, CNC controls, EDM, Electrical systems, fasteners,
hydraulics and pneumatics, manual machining, materials, quality,
soldering (that would be soft), welding, stamping. And they offer a
free trial class, which I haven't done, yet. Pretty affordable, too,
for what it is. Machinist oriented, but check it out.....
