Turning Oval Bowl With Basic Tools - Segmented (Or Solid)

Why purchase an expensive oval jig to turn an oval bowl? When, with a little planning, I can turn it.
Where is the difficulty? Actually, the final oval-ness is easy - simply(?) cut a bowl in half, then glue the rims of the two half bowls together.
To be honest, IMHO, not every bowl is suitable for this minor surgery. I had to ponder the appropriate shape.
Finally, the joint does take some sanding. However, a good flat rim that flairs slightly inward and outward reduces the sanding requirement.
As for being a segmented bowl, I did not want segments cut in half or less. I wanted a full segment at the cut line. Then, how do I overlap segment joints and still have a full segment at the cut line?
In the end, the segment rings vary in segment numbers from 6 segments per ring to 20 segments per ring for a total of 104 segments. No joints correspond from ring top ring. The 6 by 9 inch bowl is 3 inches tall and is finished with wipe-on poly. A small flat on the bottom serves to stabilize the bowl from rocking.
To avoid the appearance of huge rings as the bowl tapers to the bottom, ring height is reduced to approximate a sphere with regularly spaced lines at its circumference.
Enjoy.

Nicely done Alan, couldn't see where you were going till the glue came out lol. Cheers Geoff
Kept you in suspense. :)

When you got a bowl (at about 5:26 in the video) I thought you were going to make another one just like it. Then join the two bowls. After that proceede to the bandsaw. Then you would have two oval bowls. Either method I like it. You done good Alan. Thank you for sharing and continue to stay safe.🙂🙂
The issue that I see with that approach is getting two bowls to be the same so they match up at the rim. This way, the match is easy.

Bonjour Alan. J'ai beaucoup aimé ce travail de tournage ,c'est sublime ,vraiment. Cela me donne envie d'essayer et pour moi, ce sera au moins deux tailles au dessous .Petit à petit c'est ainsi que l'apprenti apprend ,et grâce à vous .Merci Alan👍
Certainement, allez plus petit avant d’aller plus grand.
Merci
Alan
You are very sharp. I have been subscribed for a long time. Love watching your videos.
I appreciate that! Stick with me. :)
Alan
Well done! Might be time for me to get back to turning.
Then it it time to go back.
Alan
Good job and nicely performed Alan.
Thank you
Alan
Neat concept Alan.
I'm glad you agree. :)
Alan
Very ingenious, Alan. The math seemed to be complicated, though. Maybe if I took more time it would make sense to me.
Bill
That was medium advanced math. Normal segmented math is easy.
Alan
Neat idea!
Glad you think so!
Alan
great jpb
Thank you
