Still looking for segment table on AAW website

[Ira]

Hello Again,
I am posting this question again because I have still not been able to find what I am looking for. Some of the people that replied to my original question gave some great advice though all I need is to locate the table that is mentioned in the article on Segmented Turning in the latest issue of American Woodturner.
The name of the article is "Segmented Turning School" and in the article it states specifically that there is a table downloadable from the AAW website that has segment edge length measurements for rings from 1 to 20 inches in diameter and for vesels with 6 to 20 sides or segments. This statement is in the right hand column on page 58 4th paragragh. I have looked and looked to no avail. If anyone knows where this table is please let me know.
I know the math is easy and have designed a couple of hollow forms and a bowl using the tangent formula, I would just like to have this table to check my math before I start cutting.

Thanks again!

Did you check out the link to the current issue on the AAW home page?

Ira for the first time thanks to Mark I took a look at that table. I think it has drawbacks. Your best accuracy will be using the forumulas and working by the thousands to 3 places. The table is also by the 1/2", you will waste a lot of wood when dimmensions in between are needed. Take a look here. In this case most of the diameters are near the 1/2" but not all. GT

Thank you Mark and George,
Mark, that looks like the table that is mentioned in the article how the heck did you find it?
George, I do the math using the tangent formula, I think it is pretty accurate though I usually round to the hundredths of an inch do you really think I should go to the thousandths? I thought that was a bit of over-kill. Please let me know your thoughts and thank you again.

I use dial calipers and if I don't do to 3 places, I lose track of where I am. Tenths or Hundreds is ok and working with fractions is ok too. Really it what ever works for you. When you cut on the saw and a pencil mark it can be to one side other or another. Even when thinning boards on a drum sander I like to be dead on within the 1000's or 3 places. Feature rings sanding on disc sander, same way, your sizes most be exact. Curt Theobald would get on my case if he though I didn't get to the .001. Good luck with your segmenting Ira. Show us your stuff when you get a project done. GT

I also use dial calipers to set the stop blocks on my segment cutting sleds (to set the length of the segments being cut) simply because it's the EASIEST way. My actual setting may be off by .010", but that's close enough, as the segments will all be the same length. If my chart says segments for the next ring need to be 1.567" long, it's easy to set the calipers there, and then set the stop block by the "that looks about right" method.

Hi Richard,
Thank you for your input, I just built a zero clearance cutting jig for my compound miter saw and will use my decimal dial calipers to set the block for the segment lengths.
