"        Upon removal from the oven I immediately soak the pine
        board in insulating material (I prefer paraffin dissolved
        in naphtha, but low viscosity epoxy or polyurethane should
        do).

        After a good soak, I remove it and let it dry.
"
	It has been my experience that under these conditions pine
tends to change dimensions somewhat, even if it seems to be perfectly
dry to start with.  Therefor I soak it in (very hot, to get out the
air trapped in the wood) paraffin and THEN cut or turn to exact
size.  
	This seems to work fine.
