I'm not sure what you're asking, but if it has to do with slotting fretboards for custom scale lengths, I can advise you.
Many years ago now I wrote a program called WFret, as an exercise in learning Visual Basic for Windows. It still is available and still runs, as far as I know, on all Windows machines. It allows you to input a scale length and number of frets, and prints out an accurate template (depending somewhat on your individual print drivers and system defaults) for the scale length. This necessarily must be taped together accurately - usually two or three pieces - and taped to your fretboard blank. Then center your fret saw on each line and cut the slot. I use one of those cheap plastic tri-squares as a blade guide. I've never had a complaint about my instrument's intonation.

You can get WFret here: Handmade Music Clubhouse

Also there is Fret2Find, which is web-based and works on any platform, and allows printing templates.

If you order fretboards from any of the major suppliers, you can give them your custom scale length, let them know if it's *nominal or final and they can punch that into the CNC. Some have a nominal upcharge for this.

*Even though everybody "knows" how scale length is measured, the fact is that there are two ways. Although CF Martin advertises their full scale as 25.44", that's the final or compensated length. The Nominal scale (0–12th fret x2) is actually 25.34". More than one person over the years has gotten this wrong and ordered fretboards that were too long for their guitars. At least with banjos, one need only slide the bridge a little one way or the other.

It's interesting how they refer to the scale length on guitars which have fixed bridges—I am working on a Gibson SJ, and the stated scale is 24.75", but the actual distance from the nut to the treble end of the bridge saddle is 24.87" and the saddle angles back from there. 

The distance from the nut to the 12th fret, however is 12.375", which is half of 24.75". I am aware of another one that's 24.6875".

Banjos, of course, have a movable bridge which can be adjusted as you like.  I make banjos with 26.25" scales be 13.125" nut to 12th fret and just adjust the bridge until it works.

Then Jon Whitney and Kurt Dobbins have given you the answers you need.

Let us know what you wind up using and how it turns out.

I think people are getting confused because Kurt is putting the videos on his homepage instead of linking them in his posts. Has happened a few times.
