Yeap, K-hinge name comes from MikeP ( http://rotordesign.com/bm/category/yurt/page/4/) and does involve some sewing machine time ;) but of course glue serves the same purpose with vinyl.
Your 5/8" x 1" guide gives 32 degree angle, which should be close enough to 30 :) Question is what sides are you mitering? That neargeodesic thing looks really scary and I would not be surprised if not a lot of those angles were similar or even nice integers... In fact the original paper by Harris seems to confirm that: http://www.tilings.org.uk/Hexayurt_Family.pdf That looks like some messy math :) You could label all the miter sizes on your foldout - it helped me a lot when doing the actual cutting for my yurt: http://www.appropedia.org/File:Foldout.jpg but yours is a lot more involved...
