TO MAKE A BELT PIN
The belt pin
Eighteen-gauge copper is required for this problem. The operations are like those for the hat pin except that hard soldering is necessary. The slight bending of the copper, required in this case, is done by means of a horn mallet and a sand pad. For hard soldering, the surface must be scraped as before and covered with a little borax ground in water and applied with a small brush. The belt plate should then be placed on the asbestos pad, with its convex face down, and blocked up so that the end where the soldering is to be done is horizontal. The catch should then be placed in position with a small piece of silver solder at the base. The solder should be melted as before by means of a mouth blowpipe and gas or alcohol flame. The hinge is soldered on in the same way, and finally the pin is cleaned and polished for use.
