Riffmaster

Hi all,

i'm building a guitar for a friend, i have fretted the fingerboard for scale length 25.5/648 mm, the bridge is a Schaller Floyd Rose tremolo, now i have to route the neck pocket in the body but i don't understand how to calculate it, if the scale length must be 648 mm i image that the distance from the lock nut and the bridge pivot must be 648 mm but if i try to calculate it here: http://www.stewmac.com/FretCalculator/ and i choose 24 frets and 648mm length

the caculator say that the distance must be: 633.706 mm (±0.5 mm) Why?  in another words what i have to do when routing the neck pocket?

sorry for my english!!

Be careful of printing out templates! I used Wfret  to do the same but on checking the printout I found distortion at the printer (a laser printer) gave inaccurate results. It was less than a millimetre per fret but the cumulative across the length of the board was substantial!

I got better results using a good steel rule and working all measurements (as printed by Wfret) from the nut to fret position, that way the error is not cumulative.

Thanks i will follow your hints next time, i have a regular ink jet printer and the template is very accurate, i placed it in already slotted fingerboard and is perfect!

Hi Myka thanks, i solved my problem with a software called Wfret that sw make a printable template of frets position i just cut form paper the template and fixed it onto fingerboard with doubleside adesive and then slotted the fingerboards,

before do this i checked the position of frets in another neck and it's very precise.

I have here two shaped fingerboards with these specs: lenght: 19.75 Nut: 1.75 heel:2.25 but they are unslotted, now i need to make a tool for do a precise job without mistake fret position, i don't want purcase from stewmac or others xpensive tools! any idea? tutorial online? excuse me for errors but i live in Italy i hope that someone can understand what i mean!
