Multiscale PT2

Multiscale Work Part 2

I lost some time to a new tunes system... I broke out my old Yamaha monitors and hooked them to a T-class amp. Huge improvement though I doubt my neighbors appreciate it.


Back to work on the first Multiscale.




Testing the fit of the Technology 4 Musicians single string bridge. Looks like a winner.




Looks like a fit.


Headstock wings. And the contraption I am going to use for trussrod access. I want a really small hole in the headstock so I don't need a trussrod cover. I have had a hard time getting them right by hand so I am borrowing this jig from the Telecaster guys.


Trussrods finally... ALLPARTS had them backordered since November so I had to get them from WD. Ended up being a better deal as I was able to get the 20" model for my 8 strings.


New Bobbins for the pickups... black abs.

More Multiscale Work

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.

Simple .125 slots in a template with a straight .125 guide mounted directly under the path of the blade.


The guide has to fit the slot tight. I can not have any slack for obvious reasons.


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.


This should work.


Basically this is how it works.



I used 10-32 socket heads with steel inserts to make the jig easy to line up and easy to remove.



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.



Business as usual now...

Building Multiscale Pickups

8 String Multiscale pickups
These are the test bobbins made from polycarbonate. For the production bobbins I will switch to black ABS.





Here we have a A5 .250 pole Single Coil for my beater strat project.

Gibson RD Style Bass pickup… I am not sure about the magnets I am using yet. Probably not the one in the picture… (huge C8)



And this is just silly...
