Peghead holes

I am getting ready to drill my peghead holes in a martin neck.
I have read in the forum that I should not use the Martin pattern provided but to use the measurements instead.
I understand that part. MY question is from what point do I begin my measurements? It seems to me that I should measure everything starting from the end of the freboard. What beginning reference point do you use to drill your holes?

I don't know if this is the correct procedure but it looked right when I finished. I drew a vertical line down the center of the back of the peghead. I then measured down 1 ½ inches down and drew a horizontal line. Another 1 5/8 “ down and another horizontal line and finally another 1 5/8” down and the last horizontal line. I then went back to the top line and measured so that I marked drill points on that line 1 11/16” apart centered on that line. The same procedure was done with the next two lines down but the drill points were centered 1 ½ “ apart. It seemed to look correct to me. l

Anyone else have a similar plan? Or even a diagram that could be printed and applied?

It is important to note that many tuning machines are metric and if you ever plan to use three-on-a-plate you need to have the spacing perfect. I made a drilling jig for my 12 string on a milling machine - I just set the mill for 6 equally spaced holes at whatever the correct value was and drilled and reamed the 10mm holes. The jig clamped on the side of the headstock and I clamped a piece of scrap on the back to keep it from splintering. Since I didn't have a metric brad point bit I reamed the holes after drilling them

I did start from the top of the headstock and positioned the first hole where it is on my D12-28.

I would be happy to loan the jig to anyone doing a six-on-a-side headstock. Unfortunately it won't work for yours tho

Stuart's layout is spot on --- I've seen many guitars with the tuners all 1/2" from the edge. This does not work out since the "B" and "A" need to be nudged toward the center of the headstock so the strings properly clear the two "E"'s heading to the nut.

I got a nice layout for 6string headstock from someone over on the MIMF site. The thread is still on there, I would list it here, but I'm not able to at this time. (just look for the thread "headstock dimensions for Collings/SCGC style" it's pretty recent.

looks like a nice layout to me.

thanks

thanks-

email me if you'd like a copy of this drawing - it's in PDF form.

I also have a Jpeg and if I think of it i'll try and post it later,

this drawing is not to scale, but the dimensions are copies of Collings/Sant Cruz squared type headstock.

laters,
JB
