After all the holes were drilled, and all the rib indexing was completed, we were ready to prepare the board for pressing. The indexed ribs were placed on the board, and lines were drawn to mark their location. The board is then sealed with schellac EXCEPT where glue joints will be. This requires a steady hand and a bit of care to keep the schellac off the wood that will be a glue joint. When every thing is gathered together, the glue up process begins. Each rib is individually glued in place using the index holes as locaters. A beam is placed on top of the rib, and 100 psi air pressure is applied. Each rib takes about 5 minutes, so this board took about 1 hour to glue up with 11 ribs. The press intentionally "bellies" the board with about 3/16" deflection on the longest ribs.
