Jim,
I use 1/2 in triangle stock and fiberglass cloth, I use the landing gear itself to mark the hole placement in
the cloth, cut those out about a 1/4 in. in dia. Cut your cloth to cover the entire area you want to strengthen,
plus about 1/2 in. extra. Take some 30 min. epoxy and coat the entire area with it. Not to thick, but thick enough
to soak into the cloth. Lay your cloth down in the area you have chosen, pushing into the corners and everywhere
till you have good contact throughout. Then apply some more epoxy on top of that, and work that in, soaking the
cloth thoroughly. Don't get to much epoxy, you'll know what looks about right. Then cut the triangle stock the
length of the sides and front and back. Place those in position, once again with the epoxy and glue them in place.
press them in nice and firm. Let it dry over nite and presto! your done!
I've NEVER had any area I've done this to fail. And out of the crashes I've seen when this was done to a plane, that
was the area that held together.
