<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>
