I'm trying to put together a small workshop on a budget (who isn't!) what if I took the guards off a decent [dewalt, delta] 6" grinder to mount my 8" sharpening wheels? (set from Jantz) I may also do some minor light grinding [with the stock wheels] on various other things (I have a peanut grinder for other chores) also, what if I used an external speed control, such as those sold by wood working supply houses, to slow this grinder to about 1000-1500rpm? would that do something nasty? is slowing the speed down as big a benifit as I am led to believe? the grinder I really need for this is about $200.00 out of my price range. thanks pete

Hank, get the aluminum oxide wheels for your bench grinder. The vitreous clay wheels that usually come on those can be quite dangerous. They can fracture, and that will provide possibly, the last most exiting second of your life . Seriously, people have been grieveously injured with those gray clay wheels.
One good, and fairly inexpensive 2x72 belt grinder is the Coote. They don't have a website, so here is there ph#,1-360-437-0366, in Washington state I believe.
The speed control you speak of, is not practical on more than fractional HP AC motors, like Foredom, and Dremel tools, etc. Good luck, and welcome to BFC.

Motor speed controls may be used on motors of the 'brush' type. If your motor does not use brushes (they are internal within the motor case) it may well not work well and upon loading the motor with the work piece it will slow and probably stall, but worth a try. If it does slow significantly or just stall, turn power off to the motor now.
