tsl602000 Posted May 29, 2003 Report Share Posted May 29, 2003 I drilled the machine head holes (10 millimeter) with a drillpress in two necks and the holes were just perfect. Right now when I use a 10mm drill, the holes come out as 10.25 mm and I have no idea why. Could it be the drill I use is blunt? (ehmm.... not sure if blunt is the right word.. could be "dull" too)... Anyone? Coen Quote Link to comment Share on other sites More sharing options...
vh-guitarstore.com Posted May 29, 2003 Report Share Posted May 29, 2003 sounds like the bit is walking in the hole Quote Link to comment Share on other sites More sharing options...
tsl602000 Posted May 30, 2003 Author Report Share Posted May 30, 2003 what can I do about that? Quote Link to comment Share on other sites More sharing options...
Brian Posted May 30, 2003 Report Share Posted May 30, 2003 Yup sounds like a walker, either that or during the previous drilling the bit heated up and deformed on the tip. If it's walking chances are your drilling into some really tough wood and the only thing you can do to get around it is pin down the object your drilling in to. I would first inspect the drill bit though just to be sure something didn't happen to the tip and also make sure it is seated properly in the chuck.

tsl602000 Posted May 30, 2003 Author Report Share Posted May 30, 2003 thanks for the help yes.... it's very hard maple indeed... I'll buy me a new bit today and try again. Maybe I should put a higher speed on the drillspress too? Quote Link to comment Share on other sites More sharing options...
vh-guitarstore.com Posted May 30, 2003 Report Share Posted May 30, 2003 drill a small pilot hole and use a brad point tip Quote Link to comment Share on other sites More sharing options...
ryeisnotcool2 Posted May 31, 2003 Report Share Posted May 31, 2003 yeh drill a pilot hole first, this will giude the bigger bit, and crank up the speed on the press,its woo so you can go fast. i only slow it down when im drilling metal.

john Posted May 31, 2003 Report Share Posted May 31, 2003 10.25mm sounds acceptable to me! Quote Link to comment Share on other sites More sharing options...
tsl602000 Posted May 31, 2003 Author Report Share Posted May 31, 2003 Thanks guys!!! I bought a new drill bit and will try drilling a smaller hole first. John, 10.25mm is absolutely not acceptable to me. The machinehead shafts are 9.8mm, so I'm already bothered by that 0.2 mm. I want to build my guitars within very close tolerances. If I didn't care, I could've bought a Fender.... Coen Quote Link to comment Share on other sites More sharing options...
john Posted June 1, 2003 Report Share Posted June 1, 2003 ah i see, you would probably be better off getting a 3/8" drill bet as they are slightly less than 10mm. in fact thats prob what the tuners are. hope you get it sorted anyway. i`ve seen worse than fender build quality! ...... mine.

tsl602000 Posted June 1, 2003 Author Report Share Posted June 1, 2003 yeah, you're right, but those are almost imposible to get here in Holland. The tuning machines go in perfectly with 10mm. Didn't you built a bass? Quote Link to comment Share on other sites More sharing options...
john Posted June 1, 2003 Report Share Posted June 1, 2003 yeah, i built a bass, but i hav`nt finished it yet. I have been waiting nearly 2 months for my pickups to arrive. i used gotoh compact tuners which needed 9/16" diameter holes.i could`nt get a drill bit that size so i used one i had that was slightly smaller, then enlarged the hole using a round file. it worked out very nice indeed the bushing were a nice tight fit.
