So now I have the following items - let me know what you think is missing/critical for real world wrenching on a trail rig/rock crawler.
Lift
Compressor
Drill press
Chop saw
Tubing bender
Bearing press
Table vise
Welder
Sink
Tool chests
Work benches
Engine hoist
Computer (monitor/keyboard/mouse) to look up parts
Tools: angle grinder(2), DA sander, sawzall
Off the top of my head I come up with cordless drills, cordless impact (plus related chargers on desk), a few unraveled extension cords, acetylene torch, a few shop fans, and a few small hand tools, hats, gloves, and a welding mask. Maybe a few tiny beer cans. Might add a large screen TV if I can find somewhere to hang it, and a few stools for the guys to sit on, maybe one that rolls. I am toying around with building a second level above this one that will house a paint booth, media blaster, and more storage. Ideally would like it next door to this garage but I have room to go up, but not sideways.
Alternatively I may transfer the entire garage to the other side of the room because I have a longer bench over there that I'm not using. That may be an extreme rainy day/wife is out of town project.
