Yep, made a number of discoveries with templates today that were much better discovered on pine test blank than new ash body blank:
1. 1/2" router bit actually 13mm
2. Routing template bridge location 1/4" too far from nut for scale length.
3. Pup position no where near either harmonic interval adjacent to bridge or fretboard.
So all good to find out, just annoying to think that such simple little things could completely stuff the build if you don't find them up front.
