Grinder Motor Reversing the Easy Way...

[palmermethod]

I needed to reverse the rotation of my grinder and the electrical advice on the net is greek to me. I know only about "Hot" wires. DAMHIKT.

While looking at the grinder I noticed that the base is a separate casting from the motor. So...................

I unscrewed the base casting (2 screws) and reinstalled it backwards. Tore the grinder label off and put it on the other side.

Result...Grinder works in reverse rotation with light, switch and labels on the operators side. I also drew rotation arrows on it.

Cool! My wife has told me I had the brain of a child. Maybe that's Good!

That or go to the other side of the grinder or turn it around BUT, why did you want it to go reverse? Isn't that dangerous? What do you use as tool rest?

I have two MDF Grinding/polishing wheels from Grizzly. They wonderfully for final sharpening/polishing. See at http://www.grizzly.com/products/G5937

However they are like buffing wheels. You cannot put the tool edge against the grain or rotation. You use them like a buffing wheel, and if you dig the tool edge into the MDF, it can catch badly.

With the reverse rotation you CAN use grinding jigs the same way, get your perfect polish and still keep your angles correct.

I did the same thing for a paper wheel system I have.

It gets everything very, very sharp with very little loss of steel.

You have to run the wheels away from you or your tool edge will bite into the wheels.

Charles, yes the same MDF dealeys. Very sharp finish. What are you glass-scratching? Is that glass engraving? I used to have one of the hi-speed drills but never used it.

Some call it glass engraving or etching, it is really sandcarving. Using pressurised abrasive to carve out patterns in glass. It can also frost and soft etch. If you are not carefull in your masking, pressure, or in cleaning up you just scratch everything. I use Silicon Carbide abrasive mostly(aluminum oxide causes sparks). Same abrasive as goes on the sharpening wheel. For a frostier effect you can use glass bead. You can use just about anything you can blast through a siphon or a pressure pot blaster.

I have mis-placed my work archive so I can't attach a photo to show. Several hundred disks some packed some not and I can't lay a finger on one that has any of my work photos![!]
