Not sure of a vid. Have you read the help portion of LP?
"Radial segments are cut in a manner that the number of segments shown in the Segment Selection Control will create a perfect disc. Pushing the Radial button displays the saw kerf positions on the board currently in the Viewport. "
I opened the "Sweetheart Clock" sample file, clicked on the first gen button, then the disc button to see the results as if I only did a first gen glue up. By playing with the lamination width and degrees of cut, the pattern can be changed easily. As always, having the lamination strips being as even thickness as possible will give the best results.
This is representative of the problem I have. My chevrons are even when I build my lamination, but when I go to cut the wedges for the disk they are not even in both sides.I guess I need to see a picture of what the issue is. When I glue up chevrons, I try and do them all at once. I line up the tips of the chevrons with a ruler instead of relying on the tips of the cut pieces. Accuracy in cutting is imperative. I also use digital calipers to measure the width of all cut pieces and try for less than .005" difference.
