I am using Segment Pro for the first time (first time doing a segment bowl at all!) and I'm not sure what distance, from the cut line, to set the stop. I had assumed that I would use the S.E.L number from the Summary page, but my first test pass ended up a larger diameter than Segment Pro predicted. [SOLVED See below] The specifics are: 12 Segment bowl, Row 2: Width=2.3, S.E.L=2.01, Outer Diameter=7.5", Inner Diameter=2.9" I did check "Optimize Board Widths" (which changed the board width from 2.34 to 2.30) but the S.E.L and Diameters don't change in the table when I do this. Actual results: Outer Diameter=7 13/16", Inner Diameter=3 3/16" The width of the board is 2.306" so pretty close to match. I'm using a sled similar in concept to the Wedgie Sled (but using Incra hardware) to set the two fences. The stop is set pretty close to 2.01 from the cut line. UPDATE: Note that by 'cut line', I mean the line from the outside of the blade, not the cut edge of the sled (so distance from the sled edge is 2.135"). Perhaps this is my problem??? UPDATE #2: [SOLVED] After reading thread: Title: Wedgie sled calculations I realized my error. To set the stop from my cut line, I need to multiply the S.E.L by the Cosine of the angle of the segment edge to the face of the stop/cutline. In this case it's 15 degrees. I guess I'll update the spreadsheet to add a column for the stop setting which will take the angle and thickness of the blade into account. Odd that this isn't already in the spreadsheet which begs the question, how do people set the stop given the data from the spreadsheet?
