Walking grinder stand
 

A little off of the subject but figured you guys would have some good ideas.
I've got a standard 8" 2-wheel grinder on a post type stand with a three legged base. Legs are 120 degrees apart with about a 3" circular foot at the end of each leg. I'm sure you've all probably seen them.
Problem: The grinder walks all over the floor when in use. Not a lot of vibration, but enough to let it walk, particularly when putting some pressure against the wheels.
I tried putting some vinyl pads under the feet but that didn't realy help much.
Any of you guys got any good solutions?

Larry,
Get out your hammer drill and drill three holes in your slab and install some 'redhead anchors' and you will be set.
Have fun, Steve

I'd do just what you have done-only perhaps use some thicker rubber pads to absorb more of the motion. It seems that something's pretty far out of balance if there's that much vibration when the grinder is in use. It might indicate a dangerous situation. Is the wheel chipped or wobbly? It might be a good idea to remove one grinding wheel or brush or whatever you've got at a time and see if the out-of-balance situation moderates. Then maybe trash that wheel for a new one. At least make sure the guards are in place and use your goggles in case something lets loose: I saw a guy on one of those emergency room tv shows a year or two ago with half a grinding wheel sticking out of his forehead....

Grinder Safety
 

You probably don't need to throw the wheel as they are quite easy to true up. I use a Diamond dressing stick, this is basically an industrial diamond mounted on the end of a 1/2" diameter steel bar. You just run the tip across the stone while it's running and it cleans and trues up the surface of your wheel. You will also find a regularly dressed stone performs better since they tend to get clogged up.

I paid about $35 Australian for my diamond dressing stick but they last a long time.

As for safety with grind stones there are a few things to remember:
*If you are storing a stone keep it in a dry place off the ground. Moisture causes the stone to weaken and it may blow apart.
*Before installing a stone hold it with your finger thu the center hole so it's balancing there and tap it with a screwdriver handle. The stone should ring, if it doesn't it may be cracked.
*Make sure the stone is the right size for your grinder as there are a variety of bore sizes out there.
*After instaling a new stone stand back from the grinder when you first start it up and let it run for a while before using it. If it's going to blow it'll probably do it sooner rather than later.
*When grinding avoid using the side of the stone as there isn't much strength for side loads.
*Let the wheel do the work and don't push to hard into the stone with the work piece. If it's not grinding as well or as fast as you think it should the stone probably needs dressing.
*Lastly and most importantly wear good safety glasses, goggles or a face shield. I have a pair hanging above my grinder specifically. I figure they can do a pretty good job of fixing skin and bones these days but you only have one pair of eyes.
