Pneumatic presses was RE: Emailing: P2130064

Hi Dave,
Assuming your gluing the ribs to the panel in two sessions. Do you 
re-climatize the board to your target emc between sessions? I'm of the 
opinion that this is not important as the expansion of the panel has been 
stopped by the first glue up, at least on the rib side.
