Bottoming out

The President's Challenge for June is "Hollow Forms". Like most of the other challenges I've done I take the challenge part literally. I've done a bunch of hollow forms over the years but I've never done one that is hollowed from the bottom. Tonight I chucked up a chunk of figured Eucalyptus and went to work.

This is my progress so far. It doesn't look like I got much done but I'm actually mostly done. I may take one more pass on the outside to reduce the weight, other than that all I have left is the sanding, removing the nub from the bottom, and finishing.

I wanted the hole in the top to be impossibly small, it's about 3/8" on a form almost 5 1/2" across. I only know of 1 person that could possibly pull off hollowing this form through that opening, David Ellsworth. I might be able to do it through a hole about 5/8" but that's significantly larger than this hole (0.11 square inches vs 0.30 square inches).

Bottom view. I still have to remove the nub. Hollowing was done through a hole slightly over 1" diameter. Before I started I parted off the bottom of the form to maintain the best grain match possible. The joint will be hidden in a series of small grooves on the base.

The color should end up like the first photo once sanded and the oil finish has been applied.
