First, I cut the pin down to about 1\/2 mm above the surface.\u00a0 Then with my cross peen riveting hammer, gently, so a not to disturb the cement or the pearl, tapped the edges of the pin down and into the countersink.\u00a0 I then smoothed the top of the rivet with the ball of the hammer.\u00a0 This all took about 10 minutes after which I told her to file, sand and polish the rivet head until it disappeared.\u00a0 She was apprehensive the rivet would still be visible but when she was finished….the rivet had disappeared!!\u00a0 The pearl appeared to simply float in the tube.\u00a0 $\"\"$ <\/a> $\"\"$ <\/a><\/p>\n

This next problem actually came several weeks ago.\u00a0 Student M is from Venesuela and does beautiful work.\u00a0She has been working on\u00a0several projects lately, but one is a bronze bracelet consisting of 5 rectangle shaped (actually more pillow shaped)\u00a0curved plates\u00a0that she freehand etched with some\u00a0lovely designs.\u00a0 The bracelet plates will be held together by two wide jump rings between each plate.<\/p>\n

Her idea was to add three stones to each plate….two matching top and bottom and one contrasting in the center.\u00a0 The curvature of the plates is\u00a0slight and she already knew how to create a saddle bezel so that was no problem. While the two outside stones were to be bezel set, the center stone will be prong set.<\/p>\n

THE CHALLANGE: How to accurately place and solder four prongs in the center\u00a0of\u00a0each plate at the same time?<\/strong><\/p>\n

My answer to her\u00a0was to make two pieces of wire into a ‘U’ shape with flat bottoms.\u00a0 Set them up at a right angle with the bottom of one ‘U’ crossing over the other.\u00a0 Solder them together.\u00a0 Now trim\u00a0the tips so they are\u00a0even.\u00a0 Pre-solder the tips of each prong, do all the pre-soldering protocol, place them (tips down) on the plate exactly where she wants them and solder.\u00a0 Cut the bottoms of the ‘U’ off leaving sufficient length to hold the desired cabochon.\u00a0 Result is a perfectly positioned set of prongs.<\/p>\n

Again,\u00a0 I need to get pictures of this project and hopefully will have them next week.\u00a0 Till then, Cheers and happy soldering, etc, etc,\u00a0 Don.<\/p>\n","protected":false},"excerpt":{"rendered":"
