Multiscale Fretboard.

Time to get started on the Multiscale machines... First I will need a template. Since I have a CNC there is really no reason to use the print/attach/cut method to make a multiscale. I also need this to be repeatable so time to design a fret slotting system.

I know what you are thinking. You have a CNC why design a fretslotting system. Because doing fret slots with the CNC is slow and tedious. I can slot a fretboard in 5 minutes on my current radial arm saw jig. The Multiscale presents some problems with the old pin system (which I never liked anyway) so we are going to go a different route. Once the tests are over I will cut this out of a more permanent material.

I used the saw to make the .125 slot.

I decided to use aluminum instead of hardened steel for the guide. However the aluminum I had had a rounded edge to it so after this shot I had to pull it all up and put a square edge on the guide for it to work properly.

Now for the test. Attached like any other fretboard slotting system. A little double sided tape. I chose to line up the leading edge of the board with the leading edge of the template instead of finding a centerline. Since the template is the exact same size as my neck this works fine. If the template was a different size I would have to use centerlines.

BRILLIANT!!

I think I saw Eric do this years ago so I am not taking credit. But I wanted to document how I did it so you guys could see.

The main thing I have to change is the templates will need to be cut from something more permanent in the future. But I figured I would wait until I was positive it is working properly first.

And of course http://www.ekips.org/tools/guitar/fretfind2d/ is your friend here.

Cheers! \m/
