I had a laundry tub sink with a wood countertop and some wood shelves above it.
I found this old 12-gauge cabinet for $78.50 and cut it up.
I used it to make the upper cabinets, lower cabinets and countertop for my new (more-compact) shop sink.
I used a circular saw with a metal cutting blade and a jigsaw with a bimetal blade. And my grinders.
All the middle was gone -- just the top and bottom here.
The back became the countertop.
The smaller cabinet on the side was made out of pieces of the middle. I harvested the latch and locking hardware from a smaller old cabinet I'd junked.
The backsplash was made out of 1/8" steel from a table I cut up.
The top cabinets are set up like apartment-house mailboxes. They were made out of the divider piece inside the old cabinet.
With a little paint on it, it almost looks too nice for a garage.
It's all made of 12-gauge steel, with aluminum for the horizontal edge pieces and stainless for the sink.
I didn't have any kind of plan -- not even a drawing for it. So I was pretty relieved that it came out okay.
