  • Over-planed neck blank — too thin?

    Posted by Danny da Cruz [da Cruz Guitars] on February 7, 2025 at 2:59 am

    Hi — I’m building a Thinline Tele and accidentally over-planed the mahogany neck blank. It is now 18.7 mm thick on avg and my rosewood fingerboard is 5.95 mm — for a total of 24.65 mm instead of the recommended 25.4 mm (1 inch). So the total thickness will be thinner by 0.75 mm or so.

    1. Am I still within practical tolerance and therefore should just go ahead with the build as normal?
    2. Should I try gluing a 0.55 mm maple veneer I have on hand to increase the total thickness?
    3. Do I build the neck as is and rout the neck pocket 0.75 mm shallower?

    Many thanks!

    To be clear on option #2 above, I mean gluing veneer to the bottom of the fingerboard to build up total thickness.

    Have you routed for the truss rod yet ?

      No I haven’t yet. It’s still just a neck blank.

        I don’t see any issues with a lam then. Could look kind of cool and you could tell people it was your plan the whole time. There’s no way they would know.

          Excellent. So laminate the bottom of the fingerboard? (As opposed to laminating the top of the blank, before routing the truss rod channel?). Thanks for your patience.

            It depends on how your truss rod is going in. You don’t want it to be that much closer to coming through the back of the neck. If that’s an issue, lam to the neck before you cut for it.
