Thank ya Michael,
This OTCA is a CS grade and the wales are big. (15/16 x 3/4} I made a set of inwales without the 12 degree bevel but they just didn't look right. And the thwart's and one seat would have had a large gap under the rail on the outside without some hand fitting. Soooo- after one of the new rails broke at a splice, I've decided to change it's pedigree to AA. I have some leftover 18 ft. Mahogany to use up, so bevel it shall be.
