Recently got an old leica 1800 cryostat up and running in our lab. After 
blowing the dust off and cooling it down I started sectioning some frozen 
tissues. I would have to crank the handle around between 5-10 times before 
it would cut the block between sections. Does this seem normal? How 
confident can I be that the thickness is what I had set it to? If anyone has 
ever had this problem before I would be gratefull for some advice as I am 
somewhat of a novice at this and there is no histotech in out lab.
thanks.
jason.
