Yes, I meant the compressor. The compressor is sitting on a wooden plate, which is on top of a rubber or neoprene pad. This sits on top of a metal plate that is welded to the bulkhead wall, about 3/4 of the way up. No, it is not bolted down in any way, will need to add that to my list of things to get done.

Thanks for the info.
