Tom, I would think spraying the spring would do nothing, but spraying the pivot points might. I'll try that, thanks.
Phil: The heel is the problem. I lost my strength on the flexing part, so when I sue the heel, my toes drop and I can't swing the little ball out to get the stand down. I find I can't use the ball of my foot as there isn't enough meat on the ball to flip it out either, or the swing is too hard for my foot's abilities.
