Having read many discussions on Negative Rake Scrapers...
Having watched knowledgeable demonstrators do amazing things with them...
Having tried various configurations with limited success...
The following questions are asked:
Does the included angle need to be less than 90 degrees and why/why not?
What "top angle/bottom angle" do you prefer and why?
Do all of your NRS have this same grind, if not why?
How do you raise a burr and how long does it last?
Finally, has anyone tried to raise the burr by grinding upside down with the handle up and edge down?
Thanks everyone for considering this and sharing your information and opinions. Any pics and drawings would be greatly appreciated (JKJ), as some of us are slow learners.
