RE: [Histonet] Histological dissection of bone

From:"Bill Sinai"

For the last 15 years we have been using a "gem" saw just like they use to
cut rocks etc prior to polishing.  It has a diamond impregated thin blade
1mm thick and 30cm diameter and a clamping mechanism to hold the material
(needs some modification for the shape of bone).  The specimen is
automatically driven towards the blade.  No need for fingers anywhere near
it.  It will cut specimens up to 12cm in height.  We replace the blade about
every two years.  It gives a beautiful clean cut with little heat being
generated during the cutting.

For many years we have "trimmed" bone samples on a band-saw to obtain slices
for decalcification.  The equipment needs replacing.  A risk assessment
indicated that putting a long bone through a band-saw in this way could lead
to someone getting hurt!  Is there a safer way?  Diamond saws are fine for
trimming small pieces but what about femur and humerus?   How do people
handle them safely?
