150 wines in a day. Life is tough!What pressure profile did you assume across the contact area? It seems to me that it would depencd upon the two profiles and the hardness of the two materials. Presumeably pressure would be highest near the center where the moment arm would be shortest and offer less resistance as the arm swings laterally movement.
"It was found that vibration such as occurs in an airplane will greatly reduce the static friction of a pivot or bearing, in some cases to as little as one-twentieth of its static value."
Any chance that we have enough vibration in the arm to benefit from this?What about suspended unipivots?
