Photo 1 shows the angled ceiling joists I added to the paint boot. In these panels I added 4 light boxes framed in 2X4s and 1/2" plywood backs for fluorescent light fixtures. I added 3 more on each long wall for a total of 14 in all. This is what I had in my old shop and is plenty of light. these boxes wil be covered with sheets of heavy polyethylene clear plastic.
Photo 2 shows how I framed in a couple of large crawl holes so I can blow in my attic insulation and service the attic.
Photo 3 show the vault I framed into the ceiling over the hoist so I can extend cars all the way up. MY ceilings are 10' and the hoist needs 12'-3". Incidentally, the ceiling joists are 2X10 and look at that 4x16 glue-lam beam the builder put in!! There are 5 of those monsters across the building. I have NO clue why they did that but I can hoist a CAT V-16 from one, no problem.
My wiring consists of a 100 amp sub-panel. I have 1-20 amp circuit for all the lights (24 40W fluorescents), 1 20 amp circuit that runs the swamp cooler, wood shop vacuum and paint booth vet fans, 1 - 20 amp circuit for all the plugs in the main shop, one GFI 20 amp circuit for the power in the bathroom and paint shop, 2 - 30amp 220V circuits, one for th air compressor and one for the two post hoist and a 220V 50 amp circuit for my welders and plasma cutter.
All the plug boxes are at 4' so I can put cabinets anywhere.
Photo 3 shows how I set up the lights in the main shop. One plug in the middle of the ceiling and the two light fixtures will be on either side and plug into it. The box next to the light plug is for the two post hoist.
shots of the cement slab. I had to build a retaining wall on one end where my BB goal will go. Note the big drive from the city street and the solid surface even behind the shop. Great place to stack spare fenders and bumpers.
We moved to a new house and I built a clone of the shop I just left. 1700 sqft, paint booth, wood shop 3 car bays and an in-ground hoist. It was great but there were a few things I wanted to do differently here. First, my new one will be insulated and dry walled. The bare frame in the old one was just too dark and dirty. With finished walls it will be much easier to keep clean.
First photo shows the shop in sticks. Has to be built to code and in Kalifornia that means earthquake so there are a lot of shear walls.
Second shows it ready for stucco.
Third shows the outside done. Note the forms for cement. I poured 1600 sq ft of cement around it. 19' in front of the doors so cars can get in and ALL around - no weeds to mess with. My last shop had 6' of dirt on three sides and I was constantly hacking weeds out.
