58Angela Varesano Photographic record of monel ring making: 16 Widen the inside of the hole to make room for the lead soder. The first task was to cut and file the sulfur stones to fit the holes. Select hard sulfur stones for filing. This was done by looking over the mass of loose, flat stones and picking them up and trying to file them on the grinding wheel. If it survived the initial filing, it seemed hard and could be worked with. The most desirable ones sparkled more. The stone is filed on a grind stone. The hand crank was turned with the right hand while the stone was held tight int the left hand. The left arm holding the stone was braced against the side of the body. The side of the stone is pressed on the grinding wheel and turned so as to get a round piece. This process is repeated until the stone fits the hole. The hole is tapered and the stone is tapered to fit. The stones often get very hot during the grinding process and a damp rag is used toocool it off. "Whenthe stone gets hot press it in. It's better than putting it in water because it takes too long to dry." The rag is folded into a 4" square. An electric grinding wheel can also be used to shape the stones. When all of the stones were shaped the next procedure is to solder them in place. The inside of the ring and the holes were sandpapered to prepare the surface of that the solder would stick to it. Soldering paste is then rubbed overt the holes and the inside of the ring. Ring is held in a vice during the polishing and. The electric soldering iron . Some head is melted on the tip of the iron and allowing and issmeared inside the holes and around the holes on the inside of the ring. TWhen the lead has hardened the holes are scraped so that the stones would fit snuggly. Use a small 1 1/2" pen knife blade. Clamp the ring into the vice with the stones in place.
