The average home mechanic with a few tools seldom has a place to work and is usually without a workbench. As this was my case, I constructed a bench equipment that I could easily damp to the kitchen or other table and thus have the necessary tools at hand for work. A plank, 2 in. thick, 10 in. wide and 18 in. long, was planed and smoothed up on all sides, and a vise and a bench pin were fastened on one edge.
Ill: The Bench Top can be Quickly Attached to Any Table Top without Harming It
To the under side of the same edge two blocks were securely fastened, as shown, and to these blocks two other pieces were fastened with hinges. With a bolt, running through from the top, and a thumb nut used underneath, these pieces are used as clamps for holding the bench to the table top. The top can be removed and set away in a closet when not in use. - Contributed by Wm. H. Hathaway, Nutley, N. J.
