The American watchmaker and jeweler; an encyclopedia for the horologist, jeweler, gold and silversmith .. . Remove from the lathe, select a * Number of lbs. sustained by of aline in diameter in wires of the variousmetals. Split Seconds. 304 split chuck, that will fit snugly, place the wire in the chuck, allowingabout three-eighths of an inch to project; remove the T rest of yourlathe, and insert in its stead a filing fixture. By the aid of the index onthe lathe pulley and the filing fixtures, proceed to square the end of thewire, (about one-fourth inch), of a size to fit in an American ratchetwheel. Now select two ratchets of the same thickness and size andplace them on the square cut on the wire. Proceed to round up the bal-ance of the square not occupied by the ratchets, and with the screw platecut a nice full thread on the end up to the square. Now cut oflf a smallpiece of steel wire, the same in diameter as the body of the tool, true it inyour lathe chuck and drill a hole in the center about one-eighth inchdeep. With a screw tap, of the proper size to fit the screw on the end of. Fig. 262. the shaft, which is now a small spindle, tap a good thread in the short piece is intended for a nut. With a graver cut it off to thedesired length, replace the two ratchets and screw on the nut; replacethe spindle in your lathe and turn up the nut round and true. While inthe lathe, square half the length of the nut on two sides only. This isintended for a grab or hold for your pliers in removing the nut from thespindle. You can vary the width of the cut by using two or threeratchets as is desired. In order to make the groove rounding, the shapeof the spectacle glass, hold an oil stone to the edge of the ratchets whilerevolving, which will round them very slightly. American ratchetwheels make good cutters and any width of groove can be cut. Whenthe teeth get dull they can easily be sharpened or new wheels can be sub-stituted. With this tool you can cut the solde
