The writer was recently in need of a hollow tool handle with a three-jawed chuck that would take from 0 to 1/8, but was unable to find one, although there are many kinds of tool-holders on the market. The effort to find a small grinder for awls, needles, etc., was vain. The following explains how the tools were made with an outlay of but 50 cents and a little labor. In a pawn shop a hand drill was found with a chuck of the desired type. This was bought for 25 cents. The handle and the chuck were removed from the drill, and put together to form the desired tool-holder. Then for 25 cents a circular oilstone, 2 inches in diameter by 1/2 inch thick, was bought. This was attached to the spindle of the drill, while the opposite end was squared, so that it could be held in a vise, as shown in Fig. 116. The grinder is used for awls, needles, etc., and the holder for the smallest of pins, awls, taps and the like.
