Various trials were done with moulds aof varying radii till we found the right formula for making a rib of the radius that we needed (11 feet 11 and 5/8 inches).  We ended up making two moulds, 1 of 9 foot radius and one of the final radius and transferred the stick to the final one after 2 hours of initial cooling.
