Here's what will happen: You pull a vacuum, which removes air and water
vapor from the chamber. Water evaporates from the wood and comes to
equillibrium with the wood at the same partial pressure as though the air
were present. Even though your gauge shows you still have a good vacuum,
there's noting going "dryingwise." So you would have to keep the pump
running, or starting and stopping it at intervals. If the humidity where
you live is low, you could probably dry the wood just as fast by letting it
sit on a shelf or in a pile.
