Hi AJH,
Don't bother sending me anything. In time I'll find something and if
need be I'll just flame cut a disc from flat plate. I checked out one of
our local farm supply places looking for a flat disk blade but now that
it's winter all of those types of things are gone or put away.
Impossible to find anything outside with all this white stuff on the
ground. Looks like I have enough scrap for the frame.

Hi Jeff and Paul,
It's been a few years since I assembled this concept guillotine design into a
drawing, and I emphasis concept. It was to show a principle of slicing the
fibres as the force of the blade was applied with as much rotation of the blade
possible. How the dimensions are determined can be proven using a cardboard
mock-up and leaves plenty of room for innovation relating to the features you
mention.
We have chippers that use disc blades:

They are definitely not supposed to rotate in use but easy enough to
mount so they do, the diameter is much smaller than your design at
100mm (4") diameter but they may make a simple entry for a 1/3
dimension proof of concept.
I have several but the postage may be prohibitive or I can ask a
machine shop here to assemble something given a few more dimensions.
