Mine is a mess also so no pictures. First thing I did when we moved was put a wall between the single and two car garages. Then I build a loft over the two car, ran a sub panel into the shop, each wall is a 20 amp breaker with five duplex outlets and I also have two 220 outlets, one for the compressor (60 gallon upright) and the welder/plasma cutter. The ceiling has eight double tube 4' lights, overhead pull down plugs. The shop is fully insulated. sheetrocked and painted white. There is a set of pull down stairs in the single to access the loft and also a winch for lifting heavy stuff into the loft.
Tools I have include two complete sets of hand tools, small mill/lathe, plasma cutter, mig welder, oxy/ace setup, 20-ton press, hoz. Bandsaw, tubing bender and many electric and pneumatic tools.
Yes, I have a lot of stuff, but you have to know I am 67 years old and I still want more!!!!
Right now, the shop houses my 90 Toyota rockcrawler, my 05 H-D Softail classic, and a 1978 Classic Triumph 750 Tiger.
