[TheForge] OT -12v motors

[Grover.Richardson at gtri.gatech.edu]

The question is how much HP does a normal 110 V motor have, the one used on the buffing wheel that you wish to replicate.  Find a dc motor of equivalent horsepower and you will have a pretty much equivalent grinder.  The dc motor will have different characteristics under load (shunt or series fed (bunches of gobbledegook that is not that important to someone who just wants to use it<G>), but overall should provide you with a pleasurable tool.  

Now the real problem is where are you going to get that amount of current.

All the best

What about a radiator fan motor Jerry?
Or a small starter with the extra stuff removed ?
