Greetings from the rabbit hole!
I've managed to get a couple little segmented bowls done. The wood is reclaimed 3/4" tongue and groove maple flooring, and some walnut bits. For the first one. (cutting board is the same maple)
This little guy measures a mere 5" across, and about 3" deep. I sanded through the grits to 600, and rubbed beeswax on it whilst spinning.
The second one is the same maple (literally have a truckload of this stuff), with bloodwood accents. Sanding was the same as the first, but the finish is shellac/linseed/alcohol mix.
Enjoy!
