[GreenKeys] Looking for help with KSR33

[w9ddd at tapr.org]

Idle observation.  In the 28 LPR, you have the tape and ribbon between the type wheel and the hammer.  On the 33, the hammer hits directly on the back side of the type wheel.  So I'd expect a slightly less wear to the type wheel on the LPR.  In either case you don't want bare metal.

John, W9DDD

I dont remember the size of the tubing as we are using a vinyl replacement hammer now but you cut it long enough to slide all the way to the bottom of the metal hammer T.
