Now you have 18 dust collectors. Good job!
The big electric one would probably work alright with some way to control the speed (it looks like a drill motor without the gear reduction and speed trigger). 25,000rpm with a 1/4" carbide is going to move metal really fast.
A variac maybe? Phase angle controller? I dunno.
Looks like the other side needs some attention also...sharp edges?
