I was sort of thinking of the guy with the most recent experience.

Anyone interested I can post the Sketchup file I used to build my fixture.

Go ahead and post it. I don't know if I will use it, but I am sure that there are lurkers who would be interested. I might be able to adapt it to laying out the pattern for basket illusion pieces.
Had to zip the file this board does not allow Sketchup file extension
First bowl in process with the new fixture.
60 segment per row
35 rows
2040 pieces
First row on waiting for it to dry

Not happy with my first row, the ID is way to big. Did not pay enough attention to the first couple of row when I was designing it in Segment Pro. Ended up moving the last dot in the profile designer portion of the program and re-did the first row. Much happier with the results.
Bob, nice job on the machine looks like everything works.
But, I don't quite understand the process. In the second attempt are those pieces glued down? What about the gaps, how are those filled or will they be left open for perforated style bowl?

Yes each pieces is glued down individually. The gaps are part of the bowl design, this is an open segment bowl
The first row that I put on I just cut it off, sanded the base and started over

row 10 on and 11 ready to glue on.......that 601 pieces so far
Nice work Bob, looks like the jig is working out!
Had to do it. Row 18 is on. Tomorrow we'll turn some more ID.
That puts me half way 1021 pieces so far. Lots of color in row 18

This is looking really nice. I can't wait to see the finished turned project. It looks to me that your approach to having the layers lay horizontal makes a lot of sense and should be much easier than doing it on a lathe with the layers in a vertical plane. It's nice to have a dedicated fixture for gluing up.
Yes so far it is working nicely

Finished my bowl:
10 inch diameter by 9 inches tall. 60 segments per row, 35 rows total. Total of 2041 pieces. Six different species, Maple, Redheart, Purpleheart, Yellow heart, Chakte Viga and Wenge. Design credit goes to Tom Lohman, I just changed to bowl profile

Very nice indeed!
Nicely done!
Bob,
That is really nicely done and looks great.
Question : was the CNC work you did greatly helpful to the process, or did you feel that development of the system more effort than it was worth ?
Kind regards,
Rich
Rich, It was a fun project, getting the program to work was the most frustrating part as I am not a programmer at all. The next frustrating part was locating and sizing all the components. But, now that I have it up and running I no longer have to worry about index wheels of any count. It only takes about two minutes to program another one and then you have it forever. I'll be able to do odd ball segment bowls which should be neat. Also, with the fixture you can do solid segmented rings as well as the open segment. So was it worth it, I'll have to say yes, it will be very versital and the more I use it the more ideas I'll find for it.
Obviously I'm not Bob, I can tell you a little about my involvement in computerized motion control though.
My start with stepper motors in automation goes back thirty years. That was with an Apple II.
Fast forward to now and it's much easier. About as easy as "connect the blue wire to terminal #1", etc. There are now software systems you can download free and for-pay systems. You still need to pay for various interface boxes, motor drives and related hardware. Most all the options for motion control/automation have friendly user groups for support.
The picture shows a "turning" that would be hard to do any other way than with CNC.
Bill, that is my next step. I have it working sell now for my open segment work and I going to see if I can adapt it to do the layout for basket illusion.
