Hello All,

I have a Leica Cryocut 1800 with a Reichert-Jung 2020 microtome that has sat 
for 8 years and went through a move from one academic building to another.  I 
am trying to section brook trout brain, but am having difficulty getting 
consistent sections.
I will get a good section and then the next section will be a very very thin 
shaving of usually just the top portion of the OCT block.  I have tried 
adjusting the clearance angle, made sure the blade and specimen is secured, 
replaced the blade with a new one, have tried different sectioning speeds, 
different thicknesses of the section and still continually only get a decent 
section every other turn.  I was wondering if anyone has had any similar 
experiences or if maybe the machine just needs a maintenance check due to it 
being an older machine.  I wasn't sure if the advancement mechanism may be off 
or if it is another issue that doesn't seem apparent to me.  Any help would be 
greatly appreciated.

Thanks,
