So I decided to make new necks for the other three and picked up some 3/4" x 8" mahogany, well at least it is suppose to be it. I laminated three pieces together and glued on the headstock then started on the tenon. Boy this stuff is light, not even all that hard. Instead of setting up to do the tenon with the jig and a router I decided to just rough it out and do it by hand. I used a razor saw from my RC airplane days, I think I cut harder spruce. Oh well I bought it and might as well make the best of it.
Got this far and then it occurs to me, I don't have truss rods for them, the ones I have are too long for this scale. I made the one for the first guitar just to see if I could do it, had enough of that and looked up a Canadian seller that is pretty quick to ship. They have some that are just a bit too long. Going to have to make the neck a little longer. Good thing I only cut out the one in case some things went amiss. Now what am I going to do with this neck?
