Here is the piano all stripped and sanded down, including a bunch of walnut-shell blasting on the detail work. It doesn't necessarily LOOK like it's all de-finished, but that's because the mahogany has such huge variations in pore size (which is what makes it pretty, eventually):
Here it is after a ton of finishing work. This piece is the only one that's done so far, so hopefully the rest of the piano will eventually be this smooth:
The finish process is super labor intensive because the mahogany has a very deep grain. So it takes 10-15 coats of poly, followed by 800-1200-1500-2000 grit wet sanding, then 3 stages of polish, then one coat of car wax. The hardest part is making sure you get enough poly on there that you can sand out all the surface dimples without sanding through the poly. I think MAYBE if I had sealed the surface first this might not be such a bear of a task, but it's too late now!
Anyway, here's the rest of the piano, as it sits at the moment:
and here are a few links to the older pics:
