Hi:
I'm posting this on behalf of my dad, who doesn't do e-mail.
"I am looking for the plans to build the solenoid powered 'hit-or-miss' model stationary engine that was featured in a 3-part serialized metal-working shop project in the early 1950s or possibly late 40s Popular Science, Popular Mechanics, or Mechanix Illustrated magazines."
If this rings a bell for anyone, I'd appreciate hearing from you. Thanks,
Cliff Doerksen
