Mark,
If I recall, in the plans it says that with gear down pressure the over cen=
ter link should have a modest amount of pressure meaning that the strut sho=
uld bottom out and take most of the stress.=20

Where did the over center link break?

It seems my nose gear failure was at least partially caused by an overcente=
r link that was never properly adjusted.
To be more precise, the cylinder extension put down pressure on the link wh=
en down and locked.
Combine this pressure with the air spring and lots of landings over 20 year=
s - and it failed with one firm landing in gusty wind.

Chris Zavatson suggested I look into the extension length and pressure - th=
ank you very much.
And, Angier Ames told me he solved the problem by disassembling the cylinde=
r and putting a shim inside to limit the down travel.
Thanks for that too.

I can see where this problem might develop if the locknut that holds the ro=
