litchfield Posted July 8, 2004 Report Share Posted July 8, 2004 Are they Kluson or Grover/Shaller style? Quote Link to comment Share on other sites More sharing options...
guitarmonky55 Posted July 8, 2004 Author Report Share Posted July 8, 2004 ehh.....no idea. they are the ones that came on my epiphone, the real chinsy ones with the green plasic tipped knobs..... Quote Link to comment Share on other sites More sharing options...
truerussian558 Posted July 8, 2004 Report Share Posted July 8, 2004 find/buy one of those plastic template things that have many circles cut into them but make sure they have measurments, and then line up the hole to the right circle, or you can use a compas and then round Quote Link to comment Share on other sites More sharing options...
litchfield Posted July 8, 2004 Report Share Posted July 8, 2004 Dont waste your time or money on one of those. You have 11/32" holes. Unless you want some chinsy tuners again, you need to ream them out to 25/64" (10mm). You can substitue a 3/8" bit if you dont have a 25/64".

Brian Posted July 8, 2004 Report Share Posted July 8, 2004 Welcome to the forum guitarmonky55 After you remove one of the tuners and take out the ferrule if there is one on the front whip out a scale and measure the diameter of the hole.

Scott Rosenberger Posted July 8, 2004 Report Share Posted July 8, 2004 Keep sticking Drill Bits in the hole until you find the size K.I.S.S. Quote Link to comment Share on other sites More sharing options...
litchfield Posted July 8, 2004 Report Share Posted July 8, 2004 I feel the need to advise you to keep those drill bits away from the tongue Quote Link to comment Share on other sites More sharing options...
guitarmonky55 Posted July 8, 2004 Author Report Share Posted July 8, 2004 well i tried measuring them with a steel ruler and they are 11/32 according to that. arent there special tools to ream out the pegholes for a bigger size? im pretty sure ive seen them on stewmac before.

skibum5545 Posted July 8, 2004 Report Share Posted July 8, 2004 Yes, there are. They're called drillbits. I have a 3/8" drillbit that I'd be willing to sell to you for $130 if you're interested. It is my belief that you can drill out new holes with a standard drill bit you have lying around at home. Quote Link to comment Share on other sites More sharing options...
litchfield Posted July 8, 2004 Report Share Posted July 8, 2004 No! you absolutely have to have the stewmac drill bit! Just spend a buck fifty on one at ACE Quote Link to comment Share on other sites More sharing options...
guitarmonky55 Posted July 9, 2004 Author Report Share Posted July 9, 2004 so a peghole reamer isnt what i should use? im looking at a 10mm peg hole for the tuners i want, so do i just find the matching drill bit and go at it? and would it be better to start in from the top of the peghead or bottom, or does it matter?

Brian Posted July 9, 2004 Report Share Posted July 9, 2004 Start from the top and go slow, I've done them by hand before just so I wouldn't split the wood when it came out the other side. Quote Link to comment Share on other sites More sharing options...
litchfield Posted July 9, 2004 Report Share Posted July 9, 2004 cLAMP A PIECE OF SCRAP ON THE OPPOSITE SIDE AS ERLL. sOMETOMES IT HELP TO DRILL 1/2 WAY, THE GO FROM THE OTHER SODE. Quote Link to comment Share on other sites More sharing options...
guitarmonky55 Posted July 9, 2004 Author Report Share Posted July 9, 2004 i was just talking to a very experienced luthier who told me the best way to do it would be to buy a peghole reamer and get rough size, then go through the rest with a hand drill of the size slowly. the tuners im putting in are schallers. i also noticed im going to need to drill a hole for the little metal nub that sticks out about a quarter inch from the tuner's shaft, would this best be done with a hand drill? i was thinking the best way to do it would be to mark the tip of it with some chalk, rough in the tuners and then drill from where the chalk mark shows me where it would line up...is there a better way to do this?

guitarmonky55 Posted July 9, 2004 Author Report Share Posted July 9, 2004 ok sorry to double post but ive been doing some research and ive found a way that seems to be fairly simple to do this so let me go over it to make sure it sounds legit; as opposed to spending 25 bucks on a peghole reamer i believe that a round file from home depot will get the edge of the peghole to the right size if i go slow and check the size often against my tuners. once i get it right, i will use a 25/64 drill bit in a hand drill to go about halfway through, then repeat the process on the other side. one question im finding hard to get an answer to is how would i go about clamping and placing the guitar for a sturdy drilling area, i dont have any professional setups just a table and some c-clamps, what should i do. (its an angled peghead by the way) after that, to drill the holes for the metal guides, i found a diagram with precise measurements on stewmac. i was planning on first measuring the placement out and then chalkin the tips and double checking it that way. the diameter is .096 inch, so just use that drill bit im assuming. for depth, i was just gonna go a little, then try the fit, then go a little more, then try the fit etc till it works. does this sound good or are there any serious flaws in my plan? [edit] i found another explanation that said a good way to prevent damage was to turn the drill bit backwards, would this be a good idea?
