<DIV><FONT size=2>Lance, </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I have cut the holes for the wing tube socket with a
hot wire</FONT></DIV>
<DIV><FONT size=2>and two templates mounted to the work bench at the
proper</FONT></DIV>
<DIV><FONT size=2>height to be on center of where the tube hole should
be.</FONT></DIV>
<DIV><FONT size=2>The socket hole is cut before cutting the core
itself.</FONT></DIV>
<DIV><FONT size=2>You need to make a slot in the core where the end support of
the </FONT></DIV>
<DIV><FONT size=2>tube </FONT><FONT size=2>is going to be to insert the
template that is mounted to the bench.</FONT></DIV>
<DIV><FONT size=2>I then burn a small hole thru the center of the templates in
the</FONT></DIV>
<DIV><FONT size=2>core with a hot piece of music wire held in a small machine
vice</FONT></DIV>
<DIV><FONT size=2>that is guided along a straight edge. Then I thread the wire
for the</FONT></DIV>
<DIV><FONT size=2>cutting bow thru that hole and start cutting following the
two</FONT></DIV>
<DIV><FONT size=2>templates. Start with a low heat and try the fit. If the fit
is too tight</FONT></DIV>
<DIV><FONT size=2>just increase the voltage a little and go around the
templates again</FONT></DIV>
<DIV><FONT size=2>until you achieve the proper fit. Of course you need a
variable power</FONT></DIV>
<DIV><FONT size=2>supply. Sounds more complicated than
it </FONT><FONT size=2>really is. Now when you </FONT></DIV>
<DIV><FONT size=2>cut the core, adjust your tip template to get </FONT><FONT
size=2>the proper dihedral. Works</FONT></DIV>
<DIV><FONT size=2>for me.</FONT></DIV>

<DIV><FONT face=Arial size=2>That's a hard one, Mike. Both Terry and I
use a similar method. We had a machine shop make a jig for the
cutter. The cutter is a length of 7/8" wing tube with a ground
sharp edge, but the jig to hold it has got to be made presicely. I
used to use a seemingly accurate jig made to the plans provided in a KFactor
several years ago, but my results were not good enough. </FONT></DIV>

<DIV><FONT face="Arial, Helvetica, sans-serif">Terry Brox's web site on
balsa skinned wings is very good and does show the drilling of the
servo lead hole with a tube and by hand. <BR><BR>Their is some great
information on these sites on building foam core wings. But a
very important part of a plug in wing would be the wing tube
sleeve hole in the core, to be straight and parallel to the desired
line centered and at the right angle to set the dihedral. Is there a site
that explains or shows the process of set up and drilling of this
hole? If this step is not perfect looks to me like the wing is dead no
matter how good the skinning process is.</FONT></DIV>
