Tim,
Thanks for your build log. I just started my pinky build and appreciate your head start. Back in Feb. you were asked about cutting the rabbit after the keel, etc. was glued on. I too followed the directions and it came out fine (that's all I've done so far), but all through the process I thought it would have been easier and cleaner to cut the rabbit before gluing on the other pieces. The slot is basically a taper on the center frame that abuts the keel,etc. easier to cut the taper without the keel, stem, and skew. Since I didn't do that I can't tell you which method is better.
I took Glad Tidings on as a summer project after working on a Syren build all winter. It clearly will not be done this summer!
