I finished turning this a few weeks ago, but it's been oiled and drying several times since and I finally decided to buff it this morning, with Tripoli/White diamond and Micr-crystaline. It's out of an alder burr that was still on a short length of a slab, overall length of the slab about 15" and the bowl about 11" outside diameter x 4" overall height. The wood was dry and a bit punky in places, giving loads of dust but not too many shavings, so I rough turned it to about 1/16 over sized, then painted it liberally with wood hardener and left it overnight. The next day it didn't cut very cleanly off the gouge, but scraped really well with a pair of big, heavy scrapers. I really didn't think that any worms still in the wood could have lived through that, but a couple came wriggling out after I'd finished it, so it was doused in worm treatment, left overnight and then re-sanded the next day. Once again, I left it to stand and a huge worm appeared, so I guess that the worm treatment got the last of them.
It's had four coats of thinned Danish Oil - thinned because I didn't want to fill too many of the worm-holes up, and I might well build up a couple more coats of MC wax on it as the days go by.
C&C always welcome....Les
