Segmented bowl using the scroll saw

[Rapid Roger]

I really like making bowls and vases on the scroll saw and I just finished this one yesterday.
It is segmented using three different woods...Cherry, Maple and Walnut... and I used a "new to me" technique that I get into down in the "Tutorial, Technique and Tips"  section of this forum if you care to see it.
Actually, this is my second try (I'll do anything twice) the reason is that I had another idea that didn't work on the first one. I'll  give that idea another try too later. 




The wood thickness is 3/4" and the bowl measures 3" tall  and 8" in diameter.

Keep making saw dust and don't be afraid to try new ides for your self.

PS I posted a segmented vase about two years ago using yet another (more common) way of cutting the segments. Note that my "new way" doesn't show ANY end grain in the bowl.

Excellently made Roger.  That came out fantastic.  Love your wood choices.  Thanks for sharing it with us.

Well Done. Like the no end grain idea

that's a beauty. I'll check your technique posting.

Thanks for the technique. I didn't get what you meant by "no end grain" but I do now.
Your photo shows an added center plug (looks like Walnut). Was that needed to clean up the intersection of all those sections? Getting perfect alignment would be tricky.

You are quite right, it is very tricky to get everything to come to a point at the center of the blank. I did fairly well on the first try but then ended up scrapping the bowl later.
The second try was fair but not as perfect so I used a 1/2" plug cutter and cut two plugs out of walnut and drilled a 1/2" hole in the center of the bottom piece and plugged the hole from each side to hide my Boo-Boo. Trimmed the plugs and sanded flush and "Bob was my uncle!". 
I once heard that the sign of a good wood worker was the ability to hide the mistakes and make them look like a design element. 
I'm working on a third bowl now and am having some trouble with the 15 degree angle cuts and getting things to fit into a 360 degree blank correctly. I scratched my bald  spot for awhile and then I finally came up with a "FIX" I think, we shall see. (clue...three 30 degree pieces = 90 degrees.)
Will post a photo if things come out like I hope they will.

When I was in engineering school I worked in a vibration analysis lab. We had an electromagnetic shaker - like a giant speaker magnet and drive - that could shake mechanical structures to look at resonances and find weak spots where fatigue might occur. We had strobe lights that could freeze the structure and you could photograph the shape of the resonating thing. At one time we were asked to analyze fly fishing rods for their vibration when casting. We had a bunch of fiberglass rods, and someone rounded up a split bamboo rod for comparison. We took a photo of the thick end of the bamboo rod and blew it up to a 10x10 circle, and you still could not see any space at the center where the six bamboo sections were joined. I don't have any idea how they do that but I'd guess that it is a characteristic of the bamboo as much as the skill of the builder.
 

There is no geometry to tri-sect (divide into 3 equal parts) an angle. You can easily bi-sect an angle, and you can easily create a 60 degree triangle (all sides are equal length). Unless you go to a machined-angle fence (or a fence with a machined stop at your angle) I think you'll have trouble getting 24 cut angles to add perfectly to 360 degrees. You might try cutting 11 pie sections, joining them, then using them to mark and cut the 12th section. If you can set your fence to with 0.1 degrees, then the final wedge will be within 2.4 degrees of 30 and maybe not noticeable as different.
