First little hiccup today, soon solved. The bushings for the Kluton tuners (which look great) are too small and my first thought was to dowel the holes and drill or ream them to fit. However after a quick YouTube search it became obvious that this can be solved with wider diameter bushings so some 10mm ones were sourced and ordered.
I also decided I'm going to knock the extended outer headstock detail down a bit to make it look more authentic, I need to make up some sort of template first, maybe from enlarging printed photos on a copier.
