Looking at fret measurements from StewMac, it seems that if using metric, fractions of mm are virtually impossible to place correctly.
Because mm's are so small, I think that a simple '+/- .5mm is close enough on a steel.
Fret #9 (10.135mm( becomes 10mm
Fret #10 becomes (10.969mm) 11mm
No frets, it's just slotted. I'm trying to figure out the proper scale dimension.
Hi James, if you cut the fingerboard off at the zero fret keep in mind that the scale length should start from the centre of that slot, which would be on the center of the fret crown, if it had a fret.
Be careful that if you put a saw in the slot that is wider than the slot you could shorten the scale. Then again if the whole board is going to be fretless it will not matter.
Actually, I think I figured it out. I'm gonna use the slot/position to set the nut....which is going to be all-thread with acorn nuts (for looks) on the end, so there is space under the nut. The nut will be set directly above the '0' fret.
A Bone or synthetic nut might fit with some modification, maybe a time to stretch out & try something different? Maybe share a pic, hard to say without seeing it? Define Scale dimension?

Sorry, it was late. I was trying to say I was trying to find the correct datum point for the nut/fretboard interface...
