It sure would be easier to make a workbench if I had a workbench. Lucky for me, I had a big ass hunk of butcher block counter top.
I screwed some lumber to the wall with masonry screws and attached the counter to it. I added some legs and a 2×6 to the front and voila!
I also added some holes for a pair of holdfasts. It’s solid as shit, too bad it’s attached to the wall.
