JoeyB Posted January 13, 2013 Report Share Posted January 13, 2013 The end links on the rep folded Oyster and on many Jubilee bracelets use the short 'tubes' welded in place. Does anyone have a method to open them up to take gen spring bars? I tried using a whole lot of oil and a pin vise, but the tube weld broke. Any ideas?

specialvat Posted January 14, 2013 Report Share Posted January 14, 2013 I used beauty scissors, tiny pair think they are for eyelash trimming. Sharp enough to cut the thin metal tho. Link to comment Share on other sites More sharing options...
mymanmatt Posted January 15, 2013 Report Share Posted January 15, 2013 I think the gens are 2mm. Lowes and home depot have metric drill bits, including the 2mm drill bit. That should do it. Link to comment Share on other sites More sharing options...
panerai153 Posted January 15, 2013 Report Share Posted January 15, 2013 Matt, if you dril them out, is their going to be any/enough metal left? I'm wondering, because i have several sets of end linke that are useless with 2mm springbars. Link to comment Share on other sites More sharing options...
jmb Posted January 15, 2013 Report Share Posted January 15, 2013 I've never had much luck even with tapered reamers as the solder/braze always seems to let loose. I have used the "JB-Weld method" outlined in a thread here with good results... Link to comment Share on other sites More sharing options...
JoeyB Posted January 15, 2013 Author Report Share Posted January 15, 2013 Using a 1.95mm drill bit leaves no metal, if it doesn't tear the little tube loose. As JMB said, I used JB weld on one once and it held. I think I'm going to try a combination of suggestions. Cutting the tube to enlarge it. And then try using silver solder to close it, and reset if it comes off. I'll be in the laboratory... Link to comment Share on other sites More sharing options...
