So, being the sadist that I am, I designed a closed-segment feature ring using 80 segments. I cut a template for my sled, and proceeded to cut the 80 pieces. I used the instructions from WTP for the measurements, of course. I assembled the ring, and it went together perfectly - gotta love that wedgie sled! Based on previous success with WTP, I didn't bother measuring the ring to see if it was the right dimensions - it's worked before, up to 48 segments (although a comment on that in a moment). I assembled the ring, and just now I went to place it on the bowl, the wouldn't you know, it was substantially smaller that the diameter of the bowl itself. WTF? Before I go any further, be advised that I use metric for dimensions. I can't stand fractional measurements, and for most of what I do, metric measurements work perfectly. WTP indicated a segment length of 7mm, and with 80 segments you end up with a circumference of 189mm. This is incorrect. The actual measurement should be 178mm. This is a substantial difference. The correct segment length should have been shown as 7.4mm. The end-result is that the ring is too small, and is unusable. No big deal, it's just wood and time, but still a bit annoying. So, I do have a request - would it be possible to have a point release that would change the segment report and the ring report to use fractional metric measurements when metric units are selected? I'm thinking to 1/10th (ha! ya see what I did there?) of a mm would be sufficient. If that isn't possible, then I guess I switch back to Imperial, which has the option of decimal measurements. Regarding the 48 segment ring, I did notice that it was a bit smaller than it should have been, but I chalked that one up to setting up the jig incorrectly. It was just slightly smaller, so the ring was still usable. Thanks Lloyd!
