I'm confused...segmented bowl

Use a sled, cut one angle, use it as a stop on the sled fence, flip the board and cut the other angle. See Kevin Neelys site:

's another one: luck, Lewis

Something doesn't look right. Are you sure of the 13.12 degrees? That angle divides out to 13.71952... segments. How many segments are in the ring?

No, there are 12 segments. each is 1 and 25/32 in width with a 13.12 degree angle. the bowl will be 7 and 5/8 in diameter.

I have a ryobi tablesaw and don't have the slots found in other tablesaws, hence the question about a mitre saw

For a 12 segment ring the angle is 15 degrees. 360 degrees / (12 segments x 2 angles each).

Hi Moyo, If your cutting a standard flat ring with 12 sides the miter angle is

15 degrees regardless of diameter or thickness.

If your cutting a compound ring you need to let us know what the desired slope of the bowl will be (your option) and we will give you the correct angles. The slope of the bowl is measured from the horizontal. There are 2 angles in a compound ring. One is the miter angle and the second is the blade tilt.

13.12 means absolutely nothing by itself.

In either ring the segment length (longest length) will be 2-1/16 for a 7-3/4" diameter using 12 segs.

thanks for the info, I'll try to be more specific next time. But, on a separate note, would a compound mitre saw be easier to use than trying to figure out a way to make a sled on a table saw with no runners?

thanks

Could you make a sled that indexes off the edge of the table?

Hum...this still does not seem correct to me, either. So...lets see. If I want to produce an octagon, I have to cut eight pieces with a 22.5 degree angle on each end. (360 degrees/8 angles) / 2 angles per side) = 22.5 degrees per angle. So lets try it for a 12 sided figure. (360 degrees/12 angles) / 2 angles per side) = 15 degrees per angle I suspect that if you try beveling each piece at 15 degrees on each end, your segmented container will work a LOT better.

Yes you can use a compound miter saw to make compound segments but if you can adapt a sled to your tablesaw you would be better off. If you were making standard flat rings I would opt for a miter saw but thats only my opinion. I cut all compound segs with a sled on the tablesaw. What does Ryobi use for a miter gauge? How about attaching a thin board (or two) to the tablesaw top and cutting a slot (or slots)in the bottom of the sled to run on the board (boards). Try saying that 3 times fast. :-)

Hum...how about making a sled that spans the sawblade (using a tall fence at the top and back that bridge the blade) and runs along the fence. Regards Dave Mundt
