(notice how I'm keeping my mouth shut?)  :^)

Where's the big knife switch that engages everything, with you holding onto
the handle and laughing maniacally as you pull it down?  :)

What model Miller is that in the background?

Uh,oh . . Now ya got an old millwright's curiosity up.

I spent a little time building production machinery for a muffler
factory in IN and I developed a likimng for "homebrew" equipment. That
looks very professional, Greg, now if I could just see it in action . .
.

Amish run the power company?

It's good you went with 24 Volt as you get more pull out a same size
solenoid. Did you look into fluidic air controls? Essentially, a small
portion of your air supply is bled off to a control circuit that takes
the place of the pilot voltage on the controls. They make limit and
position controls as well as the normal pressure / volume controls and
piloted valves.

Apply air pressure and you're off and running. Arvins, the factory I
worked for, back in the 70's, used then to handle the delicate
substrates for cat converters.

The key to working with air is to never forget it's compressible (
there's always a delay between pressure appication and the movement of
cylinders.  Important for timed operations) and that compessed air
follows laws similar to Ohm's Law ( Lohm's Law) in that you need to
figure out flow rates (current), pressures (voltages), and flow
requirements (amperage).

Email me with ideas and we'll brainstorm them. I needed a small wood
lathe once so I built one out of bicycle parts, a fan motor and a few 2
X 4's. Made some pretty nice turnings with it and some turning tools
ground out of old files.

Merry Christmas

Same to ya' Budd!
