poopypants Posted April 9, 2006 Report Share Posted April 9, 2006 hey all! Does anyone know what size drill bit to use to drill the holes on a vintage SD or Sub to fit gen springbars? I went to all the hadrware stores in my area and the smallest they have is 1/16th (1.59mm), which looks a little big to me... Anyone got the right size?!?! Thanks!

ubiquitous Posted April 9, 2006 Report Share Posted April 9, 2006 The 2.0mm springbar ends are 1.2mm; 1.3mm should be used to allow clearance of the ends to extend fully. Link to comment Share on other sites More sharing options...

ubiquitous Posted April 9, 2006 Report Share Posted April 9, 2006 Not sure, but I know Snap-On has a cobalt bit that size, and can be ordered online. Hobby train stores and jeweler supply houses will probably stock something in that size as well. Link to comment Share on other sites More sharing options...

Jetsons Posted April 9, 2006 Report Share Posted April 9, 2006 This one should do the trick: http://buy1.snapon.com/catalog/item.asp?P6...ore&dir=catalog Jet Link to comment Share on other sites More sharing options...
Davey Posted April 10, 2006 Report Share Posted April 10, 2006 Start with a 1mm carbid bit, then move onto a 1.2mm.. When your done use a 1.4 or 1.5mm bit to bevel the edge of the hole. Link to comment Share on other sites More sharing options...
