I ask the same first question : who knows anything about cedar-rib construction ? Did they asemble all dry ribs and steamed them all at a time ? But how could they bend so much wood at a time ? or Did they do it one at a time, bending each rib seperatly and assembling it to the next one ? But how could they join them alltogether ? I'll try to have a look at the Dan Miller's propositions, up there.
