Between a few more coats of tru-oil (15 in total) on the body and neck I have done the soldering.
The electronics cavity in the FBM-1 is quite small. Also the long wires from the switch cavity back to the electronic is only just long enough!
Straightened the neck, then used a 12 inch radius block and levelled the frets using the technique in the build manual.
Put on the neck, pick guard and pickups.
Next I will put in all the electronics.
