A %-in. bushing is turned into the side outlet of a %-in. tee. The bushing is then tapped to receive a 7/16-in. wing bolt. A tight - fitting wood plug is driven into the through way o f the tee and the ends ground off flush on the emery wheel. A slot, 5/16in. square, is then cut through the wood plug just under the bushing. Two pieces of flat steel, each 1/4 in-wide by 1/8 in. thick and 1/8 in. longer than the tee, are fitted in the slot cut in the plug as shown in the sketch. The outer end of each piece is bent at right angles and sharpened. After the points have been drawn out to the right distance, the wing bolt is turned to hold them in that position. - Contributed by C. Molloy, Philadelphia, Pa.
