I'm jealous of the room some of you guys have. I'm shoe-horned into a 21x22 box built back in 1925.
So I've got to be creative.
My main work bench is made out of a second-hand solid-core door. To the left of it is shelving made out of some hollow-core doors. I mounted them at the same height as the work bench so I could use the shelving to extend the work surface.
I also wanted a work surface at desk height (as opposed to counter height, or whatever the term is for standing benches). So I modified an old wrought-iron shelf frame and made a table I could use as a light duty work surface and also a drafting table.
It folds up or down, depending on what I'm using it for.
I recently added a small welding table, which displaced my freestanding drill press. Here it is, buried under some saws. It's at the same height as the main workbench. You can see I also raised the table saw up to be at the same 37" height.
Here's the drill press moved to the original work bench:
The vise has been moved out in front of the bench. I mounted dual-hitch trailer receivers underneath on either side of the work bench. Now my vise, anvil and grinder can move to wherever I need them.
I added a second bench for wood projects, and I made it fold down from the wall so it wouldn't eat up floor space when I wasn't using it.
I liked that so much that this weekend I added another fold-down table -- this one for welding. It disappears against the wall like the old one:
I added a third hitch dual-receiver into the wall next to it. It's braced to the studs with 2"x2"x1/4" steel angle stock.
The new table doesn't use the same type of base as the wood-working table, since it needed to be even stronger. Both of them could easily handle 1000 pounds, though. I realized I could store a lot of my c-clamps and vise grip clamps behind it, so they're out of sight when they're not in use.
That's five benches inside of one two-car garage.
