Great advise Ken!

There's a lot of.... "man I did a great landing and the leg just broke"
stories out there. I'm highly suspicious of these as being a bent leg from
landings gone by and then just the right situation causes the final failure.
This is what I was cautioning Jesse on and glad he knows it's bent, and why
I wanted a picture to show how much.

FWIW I straightened a badly bent leg for someone and added a piece of
1.5x1.5x1/8 steel angle (from a bed frame) to the existing bolts to get
it home.

I also straightened a slightly bent one for someone and he flew the
rest of the season. I do use wood blocks in the press to avoid marking
the tube and a series of small straightening bends.

I'm not disagreeing with Wayne who has far more experience, but if it is
not too bent to fly and there are no visible cracks I personally would
not hesitate to fly it home as long as the safety cable is there and
intact.

If replacing I'd consider 2024T3 tube instead of 6061T6.

As a side note, I've been doing some aluminum work on a building and it
is scary how fast I can cut a 10 foot length of .023 aluminum just by
scoring it with a box cutter and bending it. They really mean it when
they say to make sure we smooth out nicks and scratches on our aluminum
parts. I remember spending a bit of effort smoothing those stab strut
fork ends as well. The inside of the slot was fairly rough as received.
Moisture in there and the inevitable fretting from small movements don't
help in service.

No, I used what I got in the kit from you. If its standard tube I'll
get some from acs. Hopefully it doesn't snap before I can get it back
to my hangar/workshop which is 1000 miles away, and I don't have time
to deal with it until I'm done working for the season in October.

They bend once... then they snap! Most don't catch the bend first and
glad you did !

To be sure it's identical to what you have.. cut your own from 1.25 x
1.25 square x 0.125 6061-T6 tube, that you should be able to source
from someone there in the State.

That said.. didn't you build your own legs or was that someone else
I've got you mixed up with!?!
