Just finished lofting and believe I have found an error. (Checked the first 8 pages and didn't find it) Pg 61, new edition, Bow offsets, second line down shows x=4, z=2- 3/16. Hope I am not missing something, but I think it should be 1-15/16.
Pg 33 shows the frames with stringers more or less flush. Pg 34 and 35 show the stringers somewhat outside the frames, which is where I believe they were intended to be. In any case there is no discussion of what the outside radius of the stringers should be, but I think I will be rounding them off to 1/4 or so radius.
I've been toying with the idea of making the stringers out of 1/2 x 1" white oak (partially because I have lots of it) Weight would be about the same. The oak is incredibly strong and bends nicely. Also wondering about the properties of luann (meranti???) molding which is sold in strips 1/4 x 1-1/2. (I would laminate two of these to make 1/2". Varying data and opinions on its resistance to decay. Any comments on this would be appreciated.
