The little use I had for a drill press did not make it advisable to purchase one, so I constructed a device for drilling iron and brass which answered all purposes. A broken carpenter's brace furnished the chuck, which was fastened to a 1/2 -in. shaft having a detachable crank. The shaft turns in a brass tube which is fitted tightly in a hole bored in the upright. The sliding part or table is forced up against the drill with a 1/2-in. machine bolt.

Ill: A Very Inexpensive Drill Press Frame Which Answers the Purpose Admirably
The bolt turns in a square nut fastened in the opposite post. The end of the screw bears on a plate fastened on the under side of the table to prevent wear. A crank could be attached to this bolt so that it may be turned more easily.
The sliding or table part is made of a post similar to the end posts, but with guides attached so as to keep it in place. The holes for the chuck shaft and bolt should be bored on a line and exactly in the center of the posts. - Contributed by L. R. Kelley, Philadelphia, Pa.
