[GreenKeys] LF Upstop block M32/33...

[Nick England]

Hi Wayne - I've tried several sizes of tubing without luck so far - there
is very little clearance between the side of the hammer lever and the tape
feed sprocket so any tubing fat enough to strike the tape properly is too
fat to clear the sprocket.
I'll keep experimenting, shaving the sides of the tubing, etc.
