30×30? That’s a great size, too bad you don’t have the run of both sides of the garage.
almost all of my machine tools are on castors, and can hydraulically lift and lower to contact a full footprint on the floor. My shop is so small and the tools are too big for the space. Even with castors its hard tome and Tetris machines in the floorspace given. My lathe is not on castors because it needs to be level to avoid bed twist. Im fussy about the lathe running true. I’ll throw post some pics when I get a chance.
