[GreenKeys] Felt washers in TTY M33 punch

[Jones, Douglas W]

I've never punched felt washers before, but now that I've done it, it's easy, and one old felt hat can make a hundreds of washers.  The challenge:  There seemed to be some missing felt washers on the end of the sensing lever pivot shaft at the lower front of the paper-tape punch on my M33.  I suspect there may be no need to put anything there, but the shaft looks naked sticking out there with grooves for e-clips at the very outboard end.  I wrote this up in more detail here:

I'd appreciate comments.
