Tiyal Posted July 10, 2011 Report Share Posted July 10, 2011 I ordered 3 red subs from josh two weeks ago and just destroyed one. In my excitement to put in 2mm spring bars, I drilled 2mm holes the lugs not 1.2mm like I should have! Now what? into the parts box Quote Link to comment Share on other sites More sharing options...

Nanuq Posted July 10, 2011 Report Share Posted July 10, 2011 How about this: press some stout 2mm bars through there and grind/polish them flush on the outside edges. Presto: 5517 case. Quote Link to comment Share on other sites More sharing options...
ubiquitous Posted July 10, 2011 Report Share Posted July 10, 2011 I inherited a 'throw away' case that had the lug holes drilled too large. But instead of junking it, I asked my buddy J to fit some solid lug bars and managed to convert it into a 5517 MilSub gift for Justasgood...

JoeyB Posted July 12, 2011 Report Share Posted July 12, 2011 I haven't tried it yet, but have a case that the drill bit 'walked' and made the hole oval. I read a pinned post at Repgeek about using solder on the lugs of a Panerai case, and it looked perfect in the pics. So I think the same method might work in filling holes and then re-drilling. The author used 'Harris Stay Brite 1/32 solder, part #SB11, and Stay Clean Liquid Flux. I think the post is in the Panerai section or the repair section, I can't recall which.

josh_w Posted July 12, 2011 Report Share Posted July 12, 2011 What drill bit should you use for this. a #55 carbide? Quote Link to comment Share on other sites More sharing options...
JoeyB Posted July 12, 2011 Report Share Posted July 12, 2011 I use a 1.3mm cobalt for the lug holes from McMaster-Carr. Quote Link to comment Share on other sites More sharing options...
signumboy Posted July 12, 2011 Report Share Posted July 12, 2011 you could always thread a chain through it , then wear it round you neck Quote Link to comment Share on other sites More sharing options...
jmb Posted July 12, 2011 Report Share Posted July 12, 2011 Stick with cobalt. The carbide are a bit brittle and sometime grab and break as most hobbyists don't have equipment that's rigid or fast enough. They should be turned at least 2500 RPM and closer to 5000 RPM would not be out of line. Quote Link to comment Share on other sites More sharing options...
Jkay Posted July 13, 2011 Report Share Posted July 13, 2011 Are there center drills small enough for this task? They certainly would be less likely to walk, and can start your hole with precision. Quote Link to comment Share on other sites More sharing options...

JEKS Posted July 13, 2011 Report Share Posted July 13, 2011 Silver JB Weld (~$3) would also do the trick, especially if the intent is only to fill the holes to retap. Quote Link to comment Share on other sites More sharing options...
lloyd Posted July 13, 2011 Report Share Posted July 13, 2011 (edited) Get some 316L rod from your welding supply store and make a milsub with solid lugs. That is what I offered to buy it for. Use a 1.2mm drill bit. Edited July 13, 2011 by lloyd Quote Link to comment Share on other sites More sharing options...
