Handy man's workshop and laboratory . pe. The opposite end of the pipeshould be beveled to form a convenient spout. With this device bearings may be babbitted which would bevery difficult to get at with an ordinary ladle. The pipe forms ahandle which may be seized with the pliers when pouring themetal. To preserve its usefulness as a glue pot, insert a cork orwooden plug in the end of the gas pipe.—82 HANDY MAN S WORKSHOP AND LABORATORY 103 A HOME-MADE MICROMETER Get a common iron or brass bolt about ]/\ of an inch in diam-eter and about zy2 inches long, with as fine a thread as possible,and the thread cut to within a short distance of the head of thebolt. A bolt with a cut in the head for a screw-driver shouldbe used. Clamp together two blocks of wood with square cornersabout 1 inch wide, % of an inch thick, and inches long, withtheir narrower faces in contact (the width of the clamped blocksbeing 2 inches), and bore a Y^-mob. h°le through the center ofthe blocks in the 2-inch direction. Now remove the clamp, and. Fig. 123—A home-made micrometer let the nut of the bolt into one of the blocks so that its hole willbe continuous with the hole in the wood, then glue the blockstogether with the nut between them. Cut out a piece from theblock combination, leaving it shaped somewhat like a bench, andglue the bottoms of the legs to a piece of thin board about 2^/2inches square for a support. Solder one end of a stiff wire about2 inches long to the head of the bolt at right angles to the shaft,and fix a disk of heavy pasteboard with a radius equal to thelength of the wire,, and with its circumference graduated intoequal spaces, to serve in measuring revolutions and parts of 104 HANDY MAN S WORKSHOP AND LABORATORY revolutions of the end of the wire, to the top of the bench; putthe bolt in the hole, screwing it through the nut, and the con-struction is complete. The base is improved for the measuring work by gluing to acentral section of it, covering the place where
