My immediate action was to review the surface structure and think of how it could be improved...after a few hours, many cups of tea, a period of pulling things apart, machining different ideas of radiating threads a thought arrived saying 'how will the shell covers work?'. Scale was indeed the first issue to be resolved the shell needed to be large and strong enough to attach the inner pages and would my book need to stand up alone or was it OK for it to lie down?
Back to the drawing board and here is what followed:
I decided to distress the finish before adding the paper pulp and the fabric to set in the shell. While they dried - it was taking two days for each side, even with a wood burning stove going full bore- thoughts turned to the hinge!
Two razor shells that had been in my treasure box could be used, the theory being that they would cover cardboard 'stays' that attached to the accordion folds. See ref 4.11-2.6. The bonus of this book began to appear that it would look interesting when open and also flat - was I hedging my bets by not making it compulsory for it to stand up!
Oh dear after two days of nurturing and turning the first shell set had moved!!! Would this be useable? Onto the next piece and would decided if it was back to the drawing board once I saw how that one worked. At least the waiting meant I could get up to date with my admin report.
