These are both from Marine Ply Wood, the small shell is 3” diam. and consists of 42 segments and was a great test to see if my eye sight had improved after the eye surgery. With the bigger one I cut the wedges with the grain upwards rather than across and I think it gives a better effect than previous shells. I used a piece of ply 1.5”x1”x15” and cut 10 wedges for the small shell which gave me nearly 4 spirals.
The bases are left over pieces of Osage Orange. Now working on wood size, number of wedges that can be used and of course cutting angles, besides a easier way to produce the wedges. So much fun not knowing what you are doing.

They look great, I agree that the bigger one works better. You must have a lot of patience

Bob, They are really beautiful, and I agree that the big one looks better with the grain going that way.
Great stuff.

As normal, your projects get increasingly better with each attempt. These are outstanding.

Outstanding fits the description! Beautiful work. I also like the big one best, as far as the direction of cut. I saw the video on how to do this but I though you or someone mentioned a book that described the process. Do you know of a book available?

The larger shell is quite striking.

Thanks for the comments, agree the big one looks the best but more segments and work in the small one. My previous post leads you to Scroll Saw Village site where there are easy to follow instructions on making the basic shell. Working on one now using 15 wedges, could be good or could be fire wood.

G’day Bob, The more I look at the photos the more I see. Those Shells are superb, I could have sworn they started to move across the page they look so real. I would say that your eye sight is now really spot on….20/20 maybe….I am amazed how you put all the segments together.
Looking forward to more great work. By the way, the way they are mounted on a stand really sets the finish nicely.
