Frets worked out far more straightforward than I expected, and no special tools bought. it needs a good levelling now - I have a flat beech block with wet'n'dry stuck to it.
The 2 strap buttons are for easy position adjustment but mainly for stability when I stand it against anything.

Slow progress finishing this, still waiting for the pickups before routing the cavities. Happy with the neck profile now, sanded thru 400/800/1200 grit then tru-oiled wet with 800 and 1200. It's got a lovely soft silky sheen to it

Finally finished, fitted with a set of GFS Jazz Pro pickups, sounds really deep and meaty but with a really clear top end. Lovely tone for aggressive playing, maybe not the friendliest neck, could have been a bit bolder with the final thickness, but overall I'm very pleased with how she came together and how she sounds.
