This afternoon I planed down a few high spots on both the front and back plates. A bit of scraping and then a sanding with a power sander finished them off. I think they are tuned pretty close to ideal, but will check again later.
I cut the bass bar material to length and height and put it aside. Then I carefully cut out the F-holes using a specially shaped utility knife. It went very well, I didn't go outside the lines at all. Even the very delicate points didn't tear out.
