Will this technique work on a Legacy?

My technique is to carefully increase the high pressure
nitrogen bottle, constantly shaking the wing to avoid a slight bind in
the shaft that would permit a sudden jolt overpressering and damaging the
seal. I find it takes about 250-400 psi to raise the shaft. I raise it
about 4 inches on the Legacy and slightly overfill it so I can final adjust
it with tapping the pin on the schrader valve to release pressure. The
goal is to get both main even at about 4 inchs. Shake out the wing tips
to verify height.

Pete,
This is the method I use:
. Airplane on the ground, empty
. Add nitrogen to strut until it is fully extended
. Remove the filler hose
. Using a pin punch and a small hammer, make very light taps on the
Schrader valve stem until it drops to about 1/2" below fully extended.
. There is some hysteresis, so between taps pull down on the prop
(or lift
the tail) to see the actual position.

Does anyone know what the nitrogen pressure ought to be on the nose
landing
gear strut of a Lancair 360?
