Sorted the frets today. Surprisingly they were all pretty level with only three or four needing a tiny bit taken off to level them. A few have got string marks but to completely remove those I'd need to file the whole lot down and then re crown, far too tedious for this old bass. I've just levelled and polished them all. Scraped the board with a razor to clean it up a bit, it still needs an oiling and a buff but I think it'll look alright after that. It looks darker in real life than this picture.
Also glued the nut back on.
Also made the rear cavity cover, and I've glued the pickup casings. The pickups are resin filled so all I can do is run superglue in the cracks and flat and polish them up.
