My bench grinder is mounted on this three footed stand. While it does a great job holding the grinder, it's not much for holding still when the grinder is spinning. It will walk across the floor and vibrate and rattle unless you put considerable pressure with your foot on the bottom of the stand. This is partially because my garage floor isn't perfectly level or clean. After dealing with it for several years, I decided to do something about it.
Step 1: Gather Your Tools and Hardware
I happened to have some door stopper tips that I purchased with the intention of using as feet on my portable bandsaw stand. I never got around to it and haven't felt the need to do it, so I decided to use them on the grinder stand. I also had a box of 1/4-20 screws/nuts. These bulk packs are handy to have around. It's best to buy the longest length screws, because you can always cut off any excess if you need shorter screws. The only tools needed are a drill, 1/4" drill bit, and a screwdriver.
Step 2: Modify the Foot
The hole in the stopper tip is a bit too small to accommodate the 1/4" screw. I just used a drill bit to enlarge the hole a little.
Step 3: Install the Feet
Once the stopper tip is drilled out, you can insert the screws. The head of the screw fits very snug in the stopper tip. Install a rubber tip on each foot of the stand and add a nut to hold it on. You now have a very stable (and quiet) grinder stand.
