Anybody else see these at Lowes?variable speed bench grinders:cool: These should make great buffers...or for you guys with Grizzly grinders you can just put the grinder attachment on this and have a variable speed grinder.They should even work with a pully on them to make any grinder variable speed.here is a link to the 6 inch grinder,here in Ms the Lowes store has them in both 6 and 8 inch versions.I am going to get one to use as a Buffer myself.

So what do you guys think?

"Powerful 2 Amp Motor" - on the 6" model.

2 amps at 120 volts is 240 watts - about 1/3 HP presuming an inpossible 100% efficiency. The motor probably puts out around 1/4 HP - about the same we get (or used to get) on the 1 x 30 grinders. You could stall the belt by blowing in it! I suppose it would be pretty safe though even if you got your beard stuck in it.

The 8" model might have some application at 5 amps as a buffer, if some extensions were added to the shaft. I saw it priced at about $135.

Need POWER! :cool: :cool: :cool: :cool: :cool:

The slowest speed on that grinder is 2000 rpm. With a 1745 rpm motor and stepped pulley you would get 800, 1700 and 3500 rpm. (According to Beaumont metal works website)

How/where would you put a step pulley on that motor, and what would you run the belt to?

And I believe Rob is right. It's one of those induction motors they put in small Sears type three wheel bandsaws that can only be used to cut wax and such, if you feed it real slow.

They might be useful for using a felt wheel as a strop for taking the wire edge off a blade after sharpening, but your regular buffer will do that with less trouble.
 
I have one of these in 8" and I am using it as a buffer. I only use the highest speed and have never been able to even slow it down by leaning into it while buffing. It comes with one sleeve that puts the buffing wheel out away from the motor just far enough. what would be ideal would be two of these sleeves. I use some tight fitting washers on the opposite side without any vibration.
 
I new if I showed these here I would find out if they are any good:D Atill like the idea as a buffer.I have put pullies on grinders by removing the guards and rock to have a open shaft.

I should not do this but here we go. All you need is a controller from HF for a few bucks and a router of any HP and you have a variable speed motor. It works for me but I will surrender in advance. Please don't ask how to hook it up as it is not conventional and possibly dangerous to my health. Food for thought.
