> The fitting where the landing gear leg attaches to the axle broke, the
wheel came off, and the gear leg dug in. (Tongue in cheek comment follows:)
That was not helpful. (I WILL be talking this over with Travis) When we put
it back together, the new fitting will get gusseted. I am also planning to
gusset the fitting on my MKIII if it is similar. Fool me once, etc...

Just got home from Lakeland. Was sitting here drinking coffee and reading
emails when I came upon this one.

You must have missed my posts after I crashed at Muncho Lake, BC, 1 July
2000. Cause of crash: failed gear leg/axle socket.

Cure: What Brother Jim wanted to do initially and I didn't, weld the axle
socket to the steel gear leg. Been flying with the axle socket welded to
the end of the steel gear leg since rebuild. Don't need no stinking gussets
on welded .120" wall axle socket and gear leg. Works great. Wish I had
listened to my big brother.

Thoroughly tested mains and tail landing at Cedar Key, Florida, last
Tuesday.

Are you sure it is a good idea to weld to tempered steel? My
info says that doing so is a no no...Creates a real stress
riser.... I have a buddy who welded the step back onto his Cessna
172 and the gear leg cracked and came apart with the plane sitting
parked... I know it has lasted a long time....but....fwiw.... Herb

We weld, fit, drill, then send the legs to the heat treater.
