I made up a tailwheel spring to Steve's specification of hardness and it performs well. This is a chromium-nickel-molybdenum alloy with deeper hardenability than the 4140 series. It is usually refered to as a spring steel material and has 110,000 psi tensile strength in the annealed condition. Any other experience with this particular steel?

The change will be to 4340.

I am just installing the fairings, I hope for that last time before flying. I can't believe how much time it takes to do this stuff. Eventually maybe it will be back into the air again.
