My shop is in the corner of a walk-out basement, roughly 16 x 18 foot total. I lose a 6 x 6 area in one corner for a closet where the compressor and dust collector are located, along with storage for infrequently used tools.
Main area of the shop has a table saw, jointer/planer combo with a 59" bed, miter saw, router table and OSS. (The RT/OSS share a flip-top base.) There's also a 3 x 6 foot assembly table. Everything is mobile and is moved based on the task I'm working on.
Sanity is like a parachute. Just because you've lost yours doesn't mean you can take mine.
