For those of you who have larger compressors, say 60 gal and up, here's a question. They all seem to have either 3 or 4 legs with mounting holes on each. I'm told by the sales guy that you don't want to leave it and operate it on the wood pallet it came on. Which means I either need to drill holes in my garage floor and bolt it down, or something else. What are other viable alternatives, if any, other than bolting it to the garage/shop floor? Photos would be helpful.
