Technically, what I am working on here is a ‘Stave Bowl’ ... a bowl comprised of vertical staves (like a barrel) glued together before turning.
This particular bowl will turn out to be about 7 1/2” in diameter and 2 3/4” tall. The bottom and vertical spacers are walnut, and the staves are maple.
I used a software package ( WOODTurnerPro … http://woodturnerpro.com ) to calculate the cutting angles and dimensions for the staves and segments. I cut the staves and spacers on my cabinet saw, and the bottom on my bandsaw. Cutting tools and technique can vary according to your preferences and equipment … most of the segment turners I know do their cutting on a chop saw … my CMS is a POC, so the cabinet saw is, for me, the best choice.
The bowl I am making is similar to one Bob Simmons turned … check out his video ( http://lumberjocks.com/daddymunster/blog/17845 )
After doing the design work at the computer, I cut out the parts. I started with a piece of maple 2 15/16” wide, 3/4” thick, and about 24” long. The walnut base started out 3/4” thick and 5 1/2” square. I glued the walnut base to a waste block mounted to a faceplate.
I arranged half of the staves face-down on the bench and inserted the spacer between them. I then snugged up the joints as tight as I could and used blue tape along the seam, then used masking tape as a clamp to keep some pressure on.
I flipped the package over, and brushed glue (plenty of it!) into each joint, making sure I got good coverage on both sides of the walnut spacers and each stave.
I temporarily held the glued up half bowl with a strip of blue tape, flipped it so the flat edges of the end staves were flat on the bench and clamped it.
I killed a little time at the lathe cutting a socket in the bowl bottom to accommodate my four jaw chuck and #3 jaws, then knocked the waste block off and trued up the surface it had been mounted to.
The glue needs to get good and dry, so I shut off the lights and took the rest of the night off.
