��Using the Automobile Jack to Straighten a Frame

IN machine shops employes are often forced to rig up all sorts of make-shift arrangements for unusual jobs. One of

���An "old man" arrangement used with an or- dinary jack to straighten a chassis frame

these is shown in the accompanying illus- tration, which depicts a helper straighten- ing a bent side-frame member of a large automobile by means of an ordinary ratchet-jack. The manner in which the work is done can be clearly seen in the illustration.

��Celluloid Makes a Superior Stencil Cutting Base

WHILE cutting out a stencil, I picked up a celluloid triangle to use as a base. I found it to be superior to wood or glass for the purpose, as wood has ofttimes hard streaks that resist the smooth progress of the knife, and glass will dull the blade. Celluloid is even in composition and allows the knife blade to penetrate it just far enough to leave the cut without any projecting edge. — James M. Kane.

��Making a Handy Pencil-Holder of a Board

TAKE a board 8 in. long, 5 in. wide and I in. thick and saw it diagonally from one corner to its opposite, making two triangles of it. Into the side of one, bore 5^-in. holes spaced about 3^ in. apart to within ^ in. of the bottom, using the 8-in. way as'the base. Secure this in a convenient place on the work-bench. It will hold almost any length of pencil.

��Sh2et Metal as a Substitute for a Small Nut

THE loss of a small slotted nut on light machinery, such as that of a motor- cycle, automobile or motorboat means a stop until a duplicate may be had. Parts of this nature are not easily found, but a substitute may be formed of sheet metal or a piece of tin, which may be obtained from a tobacco or a fruit can. A piece of the metal is folded over back and forth five or six times, then the folds are punctured with a nail or punch. Each sep- arate layer is worked over the thread as shown. When this substitute is turned up tight, it will not work loose like the ordi- Nutmadeof nary nut. — Ronald F. Riolet. a tin strip

���A Convenient Tag-Holder for the Shipping-Room

THE illustration shows the details of a very handy and convenient shipping tag-holder. A number of tags are dropped into it the long way. As a result of the bend and flare at the end it is impossible for more than one card or tag to be thumbed out at one time. A number of these were put up in a shipping department of a shop. The arrangement was soon recognized as very convenient by the billing and shipping

���Ho'.der for shipping-tags to keep them ar- ranged so that one can be taken out at a time

clerks, who, before its installation, were always losing time and temper securing tags. — F. W. Bentley.
