    Fret Slot Jig

    Time to get off my duff on making Cigar Box Guitars for Christmas gifts. I recalled the slot cutting jig used in this bass build by Dave Black and thought my Corian scraps could be put to good use. Here's my version:

    A few counter top scraps:

    Some Helicoil threaded inserts and 10 x 24 machine bolts with washers and lock washers. Slots allow for lateral adjust-ability:

    Rounding a few corners and shortening sides to allow clamping room, if needed. The fret saw rides on the top of the jig, which is sized to cut the slots 1/32" deeper than the flange of the fret wire. I hope that's deep enough. If not, I can add shim stock under the template to deepen the cut.

    Some double sided tape on the bottom of the fret board to hold it on the template:

    Voila! We have a fret board. A test run on a 1.5" wide fret board (using scraps of Brazilian Koa left over from a flooring job...I left the finish on to see if it would work). The StuMac template is on the bench with double sided tape on it to hold the wood blank. I discovered that is not enough tape because I could feel the blank move:

    The stack of fret board blanks. Various lengths 3" wide planed to .27" thick. I should be able to get a few guitars out of this.

    Thats a nice looking miter box Ted and your are going love that setup. I started making my own temples out of the Aluminum 4' measuring sticks from HF and a 1/16" slotting blade from Grizzly. I cut the measuring stick in half and then notch the half's on both sides with different Scale Lengths. Way cheap way to have several different SL and you will want more trust me.

    Oh and your going to love that Brazilian Koa for fret boards in fact I just used up all of what I had that some guy you might know sent me

    That's a great-looking jig, Ted. Like Darren, I'm looking forward to seeing what you end up making with it.

    Great job Ted. How did you cut the perfect oval slots like that?

    Brent, I just drilled three holes close together on the drill press and filed them smooth.
