First bow I ever built (1983) was from those plans. I did change it around some, mainly just made a 60" instead of the 66". Seemed that I also used a taper and a parallel instead of only the parallels. Inner tube bands worked like a charm for a pressure system. Looking back using the half form seems weird but, it worked like great. It shot fine, possibly not quite as good as some of the more modern designs with some deflex in the limbs.
Why are you wanting to build this particular bow instead of one the newer designs?
