Thats kinda what I had suspected.... and I am looking more for a functionally solid solution here rather then a historically correct one. A quick look at the pinblock picture reveals why that historical perspective is a bit less important here. Ok... so ... would you hazard a suggestion at a crowning radius for the ribs, number of ribs to use, thickness, and a basic pattern ? I've never done this and tho I am quite confident I can get a usable result... it might be nice to both learn something along the way and acheive at least a hack or two better then <<usable>> results.
