Today I cut out the quarter knees from a piece of mahogany. I used the transom knee from the Glen-L plans as the basis for the shape. However I had to change the corner angle to match.
Using my angle finder, I determined the transom-to-sheer corner angle to be 110°, or a 10° outward rake. (The keel-to-transom rake is 12°). Of course, theory is all fine and good... I drew it, I cut it, I planed it. I still had to re-cut it to fit. Cest la vie.
With another angle-finding tool, I determined that the vertical rake from the transom to the midline of the sheer was about 5°. So, I adjusted my planer/jointer to 5° and planed the edge of the knee that will mate to the transom. Happily, it worked great the first time.
A little minimal corner-cleaning with a chisel, and everything fit great. Repeat for the other side.
Ive also heard these pieces referred to as "corner knees." Whatever the proper term is, I still need to finish sanding them.
