Thanks Whip, you are certainly correct. I was
referring to educated hands staying on plane.
I am still thinking about the hinge Pin. In Yodas
hinge board the board and pin are fixed in one place.
The hinge does what a hinge does, open and close. Same
for a hinge mounted on a door frame. The hinge board
nor the door frame do not appear to move over and back to the left to accommodate the opening. I would think that the flange
on the hinge pin would open to accommodate opening. Maintaining
the hing assembly on the left shoulder, as it goes around,
appears to me, that the hinge board or door frame would have
to move. Thanks for your input. Donn
