My woodworking shop is in semi-retirement.. but below is my car/truck shop.. I rebuild / upgrade automatic transmissions for Dodge Diesel [Cumins] Pickup trucks.. And rebuild/repair older cars.
In the photo below, my machine shop is on the left,, it has several work benches, a Metal lathe, drillpress, welding bench, sandblasting cabinets, grinder etc.. in the center my 12K hoist, on the right is my trans shop, wet-benches with drains,, lots of removed stock parts.
The shop is heated by Hydronic in-floor hot water, this keeps the shop around 40* all winter,, for day-long projects, I fire up a waste-oil burner and this big furnace warms the trans 'room' up ot 65* within an hour or so,, the rest of the shop gets up to 55* or so after a few hours.. The waste oil burner burns about 5 gallons of ATF or engine oil in 10 hours.. the wate oil if free..
Take care.. Greg
