<DIV><FONT size=2 face=Arial>David,</FONT></DIV>
<DIV><FONT size=2 face=Arial> Are you now or were you ever an
engineer ? <G> Just kidding really , but I think this is an
example of putting way too much importance in the minutia of the process. The
alcohol gets the water into the wool. The wool gets wet. Wet is wet . If you are
shower for two minutes or five minutes you don't get any more wet. I'm not
being condescending here but the bushing is saturated with water then
dries.</FONT></DIV>
<DIV><FONT size=2 face=Arial> Now if you repeat the entire process after a
complete cycle then I might be convinced that the shrinking would happen again
and the center may get too loose.</FONT></DIV>
<DIV><FONT size=2 face=Arial>We -- myself included -- can get bogged down in
details when as in this case exact science ain't required.</FONT></DIV>
<DIV><FONT size=2 face=Arial>Just my take and best wishes to you,</FONT></DIV>

<DIV><BR></DIV>Patrick -<BR>You, perhaps inadvertently, transposed my
question. I wasn't suggesting alcohol-water over naphtha (sorry for
previous mis-spelling), but the other way round. As best as I can tell,
naphtha does not contain water and is a solvent, thus, I would think it would
clean without shrinking. As far as the manufacturer's suggestions, isn't
this a similar problem for which Wurlitzer proposed using mineral oil and
silicone? And of course, who can forget the manufacturers (Baldwin)
suggestion as to how to deal with black butt corfam, or whatever)? <BR>My
fairly specific question with regard to shrinking is the effectiveness of
controlling both the amount of water in the mix (as per previous posts) and
the amount of shrinking that occurs. Why (I'm about to do that think
that Ron hates: speculate) would you assume, or find, that shrinking
positively addresses a center that is waxified?<BR>Thanks -<BR>David
