Hi there

Why not make the top plate fixed, and use gravity to retract the lower plate?
Is there anything WRT bookbinding to require the bottom plate to be fixed?


Yes, this is a design idea I have been thinking about. A couple of
possible points:

- it starts to make the thing a bit top-heavy, which is not so good.
- The 'moving' plane has to have a bit of float to it, and in this
design that would be the part which carried the whole book, prior to
it coming into contact with the fixed upper plane. I'm not sure if
this is impractical for bookbinding (I'm not an expert in the art!)

More thoughts welcome - ta.
