[Histonet] AO disposable blade holder

[David Waugh]

I have a question regarding a AO disposable blade holder (Cat# 824).  
This link should show a picture of a similar one (http:// 
www.usedmicroscopes.com/images/AO820Microtome.jpg)

The blade is tightened with a lever on the right that rotates a d- 
shaped cam. Two screws are used the set the tension that the cam  
places on the blade, once set, the cam will tighten and loosen the  
blade. The back of the holder is concave, and the front part convex,  
so that when tightened, the blade will bow. I have not been able to  
find any documentation on how tight the blade should be. It sounds  
like most holders have flat surfaces that clamp the blade, which I  
would think would have very different tightness requirements. Any  
ideas from someone who uses this type of holder on how the two screws  
should be set? Thanks, David
