That’s a mouthful, for sure. It identifies a 3-D geometric shape, formed of 12 pentagonal pyramids, each made up of 5 identical triangles. Thus, it has 60 (12 * 5) identical pieces. In this case, we’re talking about an assembly of sixty 3/4″ plywood pieces, whose dimensions and angles permit them to fit together to… Continue reading Pentakis Dodecahedron

Treating punky wood to get a clean final cut
The spalted wood I like to turn for its colorful grain often comes with a down side: soft, punky wood which shows a lot of ‘tear-out’ on end-grain cutting. Because the wood is soft, the cutting tool doesn’t get the benefit of having hard wood ahead of the wood being cut, so the fibers tend… Continue reading Treating punky wood to get a clean final cut
Trying out a new shape
I had a piece of Sabicu (an exotic from the Caribbean islands), that Talmadge Murphey brought to our April meeting. Roughly 10″ square, about 3″ thick. I decided to try a ‘square’ bowl, something new for me. I trued the square on my table saw, found the center, and mounted it on a 6″ faceplate.… Continue reading Trying out a new shape
Mosaic hollow-form
This project was inspired by one of Philip Moulthrop’s hollow-forms, which I saw in an exhibition at the Atlanta Botanical Gardens. The project begins with a simple hollow-form which will serve as the base for the mosaic work. This base can be any wood at all; it will be almost entirely carved away in the… Continue reading Mosaic hollow-form
Mosaic dish: stabilized, mold-cast, turned and epoxy finished
This project combines three uses of epoxy: (1) epoxy stabilization of spalted/rotten wood; (2) molded casting of epoxy and wood, and (3) epoxy finish coating. The wood pieces were mainly from corners cut off of half-round log blanks. Being on the outside of the logs, they were more severely spalted than the rest of the… Continue reading Mosaic dish: stabilized, mold-cast, turned and epoxy finished
