The pattern is now to be removed and all the lines gone over with the tool to make them deep and uniform.

The surplus stock around the edges may not be cut off.  A neat way to finish the edges is to punch a series of holes entirely around through which a thin leather thong may be laced.  If it is desired to “line” the inside, this should be done before the holes are punched or the lacing done.

** Gear for Model Work [225]

When a gear is needed to drive a small pinion and there is none of the right size at hand, one can be made in the following manner:  Turn up a wood disk to the proper diameter and 1/4 in. thicker than the pinion, and cut a flat bottom groove 3/16 in. deep in its face.  The edges should be about 1/8 in. or more thick on each side.  Measure the distance between centers of two adjacent teeth in the pinion and step this off around the periphery in the bottom of the groove.  Drill holes into the wood on each point stepped off and insert steel pins made of wire, allowing

the end of each to protrude just far enough to act as a tooth.  In this way a good gear for light work can be quickly and cheaply constructed.  —­Contributed by Henry Schaefer, New York City.

** A Home-Made Vise [226]

While making a box I had some dovetailing to do, and as there was no

vise on the bench I rigged up a substitute.  I secured a board 3/4 in. thick, 3 in. wide and 20 in. long and bored a 1/2-in. hole through it, 1 in. from each end.  The board was then attached to the bench with two screws passing through washers and the two holes in the . board into the bench top.  The screws should be of a length suitable to take in the piece to be worked. —­Contributed by A.

** Cardboard Spiral Turned by Heat [226]

A novel attraction for a window display can be made from a piece of stiff cardboard cut in a spiral as shown in Fig. 1.  The cardboard should be about 7 or 8 in. in diameter.  Tie a piece of string to the center point of the spiral

and fasten it so as to hang over a gas jet, Fig. 2.  A small swivel must be put in the string at the top or near the cardboard, if it is desired to have the spiral run for any length of time.  The cardboard will spin around rapidly and present quite an attraction.  —­Contributed by Harry Szerlip, Brooklyn, N.

** A Workbench for the Amateur [226]

The accompanying detail drawing shows a design of a portable workbench suitable for the amateur woodworker.  This bench can be made easily by anyone who has a few sharp tools and a little spare time.  If the stock is purchased from the mill ready planed and cut to length, much of the hard labor will be saved.  Birch or maple wood makes a very good bench. and the following pieces should be ordered:
