I have experienced, in varying degrees and ever since the plane was first 
flown, a shake in the airplane that happens between 12 and 15 knots when 
slowing down after landing.  I have had the strut updated, the strut is 
properly filled, the main tires and nose tire are brand new, balanced and 
properly inflated (mains 65#, nose 50#), the toe-in and camber are correct.

When the shake happens, I can feel it mostly in the control stick.  I get 
almost no indication through the seat or floorboard and cannot detect 
movement visually over the cowling.  I do, however, see a serious shaking of 
the horizontal stabilizer.

The vibration does not occur on acceleration or when taxiing out at 12-15 
knots.  It only happens on decelleration and no position of the control stick 
will stop it.  I have tried no brakes, some brakes and hard braking and 
nothing seems to help.

I would appreciate any input anyone may have about where to look next.

Thanks.
