Made some progress on my latest build - a LP reso uke. Neck is almost ready for poly. Cut the hole for the plate in the box, then measured and cut the holes for the neck in the box.
What I FORGOT was that the fretboard is overlapping the box so when I dry fit the neck, the fretboard was too low! Luckily it was just the thin box bottom. This meant I had to use the only flat file I have - a tiny one - to thin the bottom of the fretboard overhang. It came out fine and will work great. Took forever, though.
Live and learn. Now I'll know the next time I do an overhang.
