 I agree with Don completely. I did this experiment for the chapter a =
few years back with a 1" Forstner bit and scraps of 1X6 lumber. The =
holes in the oven dried wood, after 'rehydrating' (I even soaked some =
pieces under water) were so big, even the least adroit member of the =
chapter could toss the drill bit through the hole from 5 yds away and =
not hit the sides of the hole :-)  That kinda proved the hypothesis for =
me. I've always thought of the flange bushing system as an =
animal/vegetable kingdom symbiotic relationship, in humid times when the =
hole is larger, the bushing cloth picks up moisture and takes up the =
slack, and vice versa. Simplified thinking yes, but that's how I get by.

I've been off list for a long time, feels good to be back (at least for =
awhile) Thanks everybody.

  Terry,

  I have done the exact same test you did with very definitive results.  =
Try again, but start with the wood either dry or wet - not in the =
middle.  Bake a few flanges in the oven at 250 degrees for and hour, =
then drill the holes right away when you take them out.  Check the fit =
after drilling, then check them the next day after the flanges reside in =
your wet chamber for a while.
