Also it forms around the tuning pin and thickens it up as = well thus making it tight in the hole.</FONT></DIV> <DIV><FONT size=2>In your test, did the pin become tighter than before = applying CA ?.</FONT></DIV> <DIV> </DIV> <DIV><FONT size=2>Doesn't Ron N write nicely, wish I could have said that.</FONT></DIV> <DIV> </DIV> <DIV><FONT size=2>Tony Caught ICPTG<BR>Australia<BR><A href="mailto:caute@optusnet.com.au">caute@optusnet.com.au</A></FONT></D= IV> <DIV> </DIV></BODY></HTML>
