A DIY Microtome

"microtome (from the Greek mikros, meaning "small", and temnein, meaning "to cut") is a sectioning instrument that allows for the cutting of extremely thin slices of material, known as sections." (from Wikipedia)


They also cost actual cash money...from an economical $69.75 for this 'Hand Microtome' from The Science Company.  Which says that one turn of the base will create a 0.5mm section, and is calibrated to create 10 micron sections, so 1/50th of a turn = 10 microns, a full turn = 500 microns or .5 mm.


Or you can spend $12,445 for a unit which can create,  a 0.5 micron section.


But building from the DIY philosophy, you can build a pretty nifty Microtome with with a bit of wax a 1/4" - 20 nut and bolt, and a razor blade!  With all credit, like many good DIY ideas, this one comes from an older book.  See below for details...
