Hi Jack and welcome aboard...!!!
If you are thinking machine shop tools, you need look no farther than PM Research kits.
They are the most accurate and most complete set of tools available.
In the set-up below, you can see their display for model engine shows.
You could easily replace the steam engine with a small hit and miss engine.
The M91 would make a suitable power source for these tools.
If you decide to go this route, I have some of these kits.
Enjoy,
Gil
