Interesting concept Brian, but with a weight capacity of only 33 lbs. and the probable transfer of vibration, I do not see it as a good option. I am not sure how you intend to use it, but it doesn't seem to accomplish anything except to possibly raise the grinder a few inches. Tilting a grinder doesn't seem to be necessary nor advisable and the configuration does not seem to permit it to fasten to a wall and support a grinder. Perhaps I am missing something.
But, you are not asking for advice as you have already purchased it, so I look forward to hearing about your experience with it.
