[pianotech] Sealing the air leak on a AMPICO (not Duo-Art) takeup spool (Correction)

[Duaine Hechler]

Was at the customers' today for over two hours - with my doughnut punching equipment and still could not get the any 
punching to work right.

HELP ??

Left flange looks something like this (except with a little more angle in (kind of like a reducing nipple)):
__________
                     \__________
                      __________
__________/

The left end of the spool looked like it had a "ball bearing" flange - where the inside turns.

What about an rubber "O" ring ?
