Shaping wing tip skids

Excellent product. Have had them on my plane (Discus) for a few years.

For those concerned that hot shot racing pilots don't use tip wheels, I
noticed that the 2nd place finisher in the 18m class in the last World's
(Uys Jonker) was flying with tip wheels (the Jonker version) on his JS1-B.

I stopped using tip skids and went to wing tip wheels years ago. Neat
little nylon wheels mounted in a Delan housing, About the size of
Libelle tip wheels with a fared-in housing. The Delan housing can be
shaped to the wing contour by tapping a sheet of 40 grit to the wing
then sanding the housing to the shape of the airfoil by moving the
wheel housing span-wise until a perfect match is obtained. Google
Williams Soaring for photo, price $150. A wing tip wheel makes it much
easier to move the ship without any help or ground handling equipment
as is necessary for an aero-retrieve.
Cheers,
JJ.

I have a pair of wing tip skids from Wings and Wheels. They are the
white ones, described on the website as "Gray/white soft rubber-like
material skids". I need to shape them to fit the curvature of the
wing. I have considered using the cylindrical end of my belt sander
but am concerned with loading up the belt very quickly and rendering
it useless. Six inch wide belts are not cheap. Has anyone tried to
shape these to fit the wing?

I have spent countless hours using a variety of glue, etc, and two
sided tape solutions. Can't say I have been successful. One sticks
and the other with the same solution doesn't. Wrote the supplier and
after a brief exchange didn't t get a response back. My suggestion is
to send them back and look for something different. Grinding and
shaping is the least of you worries. and.. don't throw away your old
tips. You will become very adept at reinstalling them.

You should also read my earlier post. We tried at least five
different glues/tapes before giving up. These white wing skids are
seriously ungluable!

I ended up screwing the skids to a shaped thin plywood base which I
then stuck to the wing with the usual 3M double-sided heavy duty
tape. Plywood is easier to shape to the wing too.

Have you guys tried Shoe Goo? I use it in modeling to hold wiring and
nose weights. etc. Sticks like crazy...........I just removed a lead
weight and it tore the structure out, stretching like rubber. Get it
in your local hardware store.

Yes, great stuff and pretty much the same as Goop. Used it to attach a
set of Williams Soaring wing tip wheels on an RS-15 which was still
holding strong after three years when I sold the sailplane. Those
wing tip wheels are great.
