The copper section is where I'll do my welding on small projects, and the copper sheet is so the welding spatter doesn't stick; it will glob onto the stainless.
This weekend I'll have some thin strips cut to cover the 2x4 facing of the bench, just for the bling factor.
The air compressor is outside in it's own sound-insulated shed, and the supply line runs underground and into the side of the shop. This cools the air substantially; so much that I had to install an auto drain on the water trap. If you look closely in the 4th picture you can see one of the air drops; there's another right in front of the lift, below the hose reel, and another by the door.
