Anti Fatigue Mats | Canadian Hobby Metal Workers & Machinists
I recall having to cut some 3/4" rubber mats that look similar to horse stall mats, and are certainly just as heavy. I used them under our washer and dryer and also for vibration feet under my 60 gal compressor. I think I cut them with an abrasive cut off wheel and remember thinking "this shouldn't work," but it did. Go slowly.
