When we remodeled our bathroom we removed a spa tub, which we seldom used, and I rescued an electric motor. It’s been sitting in the garage ever since. The motor is 3/4 hp and 3450 rpm. Any tool projects come to mind? The only tool I don’t have is a lathe. What have you guys made with old electric motors? Thanks…

So far I have made a 16” drum sander and an air cleaner. I think either an edge sander or belt grinder are in my future at some point.

The guys on John Heisz' forum build stuff like that all the time, might check in over there. Also homemade tools for lots of ideas.

3450 is fast so for some things you will have to slow it down with pulleys. You could use it on a lathe but you would need a jackshaft or VFD if you can put one on a single phase motor. I used a DC motor with treadmill controller on my lathes, simpler.

Yeah dust collector blowers are almost always 3450 rpm, and typically in the 1-2 hp range, so a downdraft table is a good idea. Matthias Wandel has a bunch of stuff on making your own blower.
