Thread: Buffer RPM questions

The reason I use a variable Delta is completely about price. It is the cheapest ~1750rpm motor you can buy, basically (I think I paid $115 for it), and, I do occaisionally dial it up to 3400 for certain things, which is nice.

I just wanted to clear it up that if money were no object, i wouldn't recommend it. Obviously baldor or caswell would be preferred.

Also, as Glen has mentioned, the motor gets in the way when using 4" wheels, I have to move my wheel to the other side in order to do the other side of the blade. Pretty big annoyance, costs me a few minutes overall. 3" or 2" wheels are impossible to use on it.

For 6" & 8" wheels though, it works great, no clearance issues with the motor. 8" wheel @ 1750 is too fast though, IMO. you really need an 1100rpm buffer if you want to use 8" or 10" wheels for greaseless.

I really like about 2500sf/m for greaseless. I dial up my 4" wheels to about 2400rpm to acheive that speed, and run my 6" wheels at 1750rpm...which yields ~2650sf/m.
