[Histonet] sectioning old GMA blocks

[Frank Rosenthal]

Dear histonetters:

	I have a 5030 Hacker rotary microtome (bench model) and I am trying to
understand the mechanics of how the tissue block advances toward the knife.
(I don't know if the same principles applies to all rotary microtomes.)
Apparently different portions of a constant radius arc are used but I don't
quite understand it.   Has anyone seen a good explanation of this?

	Thanks.

Frank
