<DIV>I would be concerned about weakening the wing tube by drilling a hole near the center, the compression and tension forces are at their maximum. But your experience shows it works, the tube must be much stronger than it needs to be. <BR><BR><B><I>Dennis Cone <cone.man@verizon.net></I></B> wrote:

The stop at the inside end<BR>of the tube is a 1/4" piece of wing tube material with a slot cut in it so<BR>it fits inside the tube and glued in place. After two seasons of flying, for<BR>whatever reason, the wing tube can now push itself past this stop and wedge<BR>in the tube socket. It is a minor annoyance, but I was pondering possible<BR>fixes. One was to cut teeth into an old wing tube and grind a bit of the<BR>existing stop out, then pushing an 1/8 plywood disk to the bottom of the<BR>tube and securing with a few drops of foam safe CA.<BR>><BR>> Anyone run into this problem before and have alternative methods of<BR>repair? Thanks.<BR>><BR>><BR>> Bob Kane<BR>> getterflash@yahoo.com<BR>><BR>>
