This shell is 7” diam. using Marine Plywood, Purple Heard and Osage Orange, sanded to 600g and a coat of Poly.
The swirls that would have been hidden in the center I substituted with some ply wedges and gained a 3 1/2” diam. second shell. The feature wedges were cut thinner than the ply making those 3 wedges the same thickness as 2 plywood wedges, there are approx. 35 wedges in each shell.

Geez Bob, you are getting real flash. I wonder what is next.
This is great, and I love the colour combinations.
Thanks so much for sharing your creations with us.


-- Bob, Western Australia, The Sun came up this morning, what a great start to the day. Now it's up to me to make it even better. I've cut this piece of wood 4 times and it's still too damn short.

Bob, I am sure you must have a Harry Potter Wand to create such beautiful work!!!!!!!


Bob, That quality marine ply certainly paid off, not a blemish, knot or void that would be present in a low grade ply. Really classy ply. Is it made in your State?
I am amazed at how thin you are able to cut the ply. What was the thickness of the sheet? The three different woods blend very well and sit nicely on the base…..what is the base made from? Good also that you were able to gain another shell. 36 wedges? That is a huge effort to put all that together, great project!!!!!

I am overwhelmed at the way you make these turn out. Great work Bob. Something like this may never be on my list, only in my dreams.

Bob, my Beloved Buddy, these Things are an utter mystery to me. A blog, perhaps, or, even, a video of the process? I think I understand (somewhat) the Ribbons. But these Things. Something enigmatic lurks in your brain.

Chadrat, Mark have a look at and under shells there are a couple of videos on cutting the wedges and segments and forming a shell. Personally I didn’t like them and experimented with numbers of wedges to use, varied the thickness and played around with angles, just use some 4×2 pine to practice.
Thanks all for the above comments, Pete you got to be good to be an Aussie and get a DT3. Cliff watch for a PM.
