HP series landing gear info needed

It's easy to know when its set up right;
when the system is assembled sans O-rings the pistons slide in and out
of the cylinders with no appreciable drag.

My ship would have failed that test. By the time I'd noticed this (I
was the third owner), the damage to the oleo cylinder was done and I
didn't really have a clue as to how about putting it right. It's
awfully hard to make holes that are in the wrong place go away so you
can start over.

Take a look at how the thing is built. Ask yourself what prevents
metal/metal contact in the cylinder bore. In my case I think the
piston (the very end, just past the o-ring groove) is what chewed up
the cylinder bores. I remember trying to use a brake cylinder hone to
clean things up. It might have helped a little. My ship may have had
some gear alignment issues that pushed it over the edge. Obviously,
it worked fairly well for others. I've seen other HPs with flat
struts over the years. If I were doing it over again, I really would
weld the sucker (make certain you get the alignment exactly right).
Who needs a shock strut when you land at 30 mph?

Brad,

You keep the dirt out with a set of BMX bike fork bellows.

The oil is Honda SS-7 5W.

For those involved in this discussion they should be reminded that the landing gear in question is being installed in an HP-24 which has spoilers, NOT large span landing flaps.

Still, the struts on the few HP's I've helped work on are fine after
decades of use. Brad will be landing at a higher ground speed than an
'18, but I don't see how that dictates rougher landings. My glider
has a smaller mainwheel and ZERO suspension. Once or twice (maybe
more!) I've thought some suspension would be nice!
Cheers,
Jim

Landing in a rough field makes a pilot appreciate a suspension on the
landing gear. Landing faster in rough field makes a pilot REALLY
appreciate a suspension on the landing gear. A well done suspension can
reduce injury some crash situations, but I don't know if the gear in
question was designed to do that.

My understanding is that Dick having survived a few crashes was a big
believer and building strong crash worthy aircraft.
This was one of the reasons that nearly all of his designs had the
Oleo Strut Landing Gear.
I am sure it saved him from further injury in some of his adventures.
I have done at least one landing where I was very glad to have it.
