Thank you, Gentlemen. From my perspective, I think my reasoning has followed Mr. Grepper's pretty closely, but I'm starting to get used to being wrong.
Let me preface this with a disclaimer, please. I'm sorry that I don't understand exactly what you're trying to accomplish, but I truly only wish to help accomplish anything, anytime. Every time.
I only suggest 1/2"- 3/4" manila rope because of it's individual uniformity and abrasive quality. It doesn't have to be exactly the same as the next brand of rope. Just get 100' and you can do a lot of testing. When you pair it with the accuracy of a BESS machine, you might only need to make ten cuts.
I've been cutting rope for many years. I've asked around, and rope doesn't care what type of edge you provide. It has to be as consistent as dicing hogs or dissecting carrots.
Mr. EOU, before you go through the trouble of building a machine as you describe, wouldn't it be just as easy to use the weight of the knife, and draw it across whatever you have that's hard?
Maybe start with an ordinary water glass, as ordinary glass is amazingly consistent at about RHC 54, or Mohs 6.5.
I know the weight of the blade would be a variable. Maybe just keep using the same knife or knives in the same manner. Maybe tape some quarters to the blade to add consistent weight.
Maybe use a DeWalt HSS drill bit, which would be harder, but probably the same hardness no matter where find one. It would even roll on a hard surface to eliminate galling, if that's a consideration.
If you need something really accurate, precise and homogeneous, Wilson Rockwell Test Blocks are about the limit.
Am I even close?
