[Histonet] LKB 7800B KnifeMaker

[Markus F. Meyenhofer]

It is an alignment problem. Also chipping at the scoring line indicates a 
too high pressure of the scoring wheel onto the glass (there is a set screw 
to loosen the pressure next to the scoring wheel, you have to remove the 
head to adjust). I have an instruction sheet with drawings to align the 
knife maker.
I can send you a copy.
If you still have a problem after alignment, I can recondition and align, 
add a new scoring wheel/pin for a modest charge. Please contact me off line.

Does anyone have some quick tips for adjusting a knife maker, specifically a 
LKB?
We have the guide that came with the equipment. However, it's not very clear 
(to me) how to adjust the alignment based on what the guide says. It just 
seems to be an index of sorts without very much advice on how to realign the 
machine.
Basically I'm getting knives, even squares, that are not straight on the 
edge. So, I think the scorer isn't lined up right. But, when I get squares 
to break, the pins seem to be too far to the edge because there's sometimes 
a lot of cracking and chipping that's going on too...
The head histologist in the lab says she fixed it, but if anyone could help 
with general tips and/or guidlines for the future, it would be much 
appreciated!
Thanks.
