Bouzouki restoration

I've been restoring this instrument I made some 34 years ago. It started out with 4 strings and tapered violin pegs, but about 4 years ago I really wanted a bouzouki, and since I couldn't afford one, I decided to convert this (I used to call it a) dulcilyn....kind of a combo between a dulcimer and a mandolin. I added 4 more strings with tapered pegs and drilled out the bridge and peghead to accomodate them. It was an experiment that turned out surprisingly well. It had great tone and volume. However, the neck was a little clunky, the tapered pegs were really hard to fine tune, the frets needed dressing and there were cracks in the back and one in the top. So I've fixed all these issues, and have new machine tuners to install, fixed the cracks and loose braces inside and out.
I filled the back with epoxy last night, sanded it down to 320 this morning, and placed a cross-grain spruce patch under the crack at the soundhole, working glue into the crack as well. After resanding the whole thing with 320 wd paper, I began spraying lacquer this evening.
