Topic: Sharpening burrs > RE: +Grinder For Press (3 msgs / 44 lines)
1) From: miKe mcKoffee
IIRC a few years ago Pecan Jim tried sharpening his SM (not +) burrs, gave
up and ordered new upper burr (at the time lower burr could not be
purchased), gave up on the worthlessness of just replacing the upper burr
and bought a better grinder.

Mike has a very good memory.  Also, I grind stones for jewelry so I  
am used to doing very precise grinding.  I don't remember the details  
of why it was not working but I do remember a high level of  
frustration. \

sharpening hardened steel especially conical brurs is a very precise 
action to be performed.
A file is out of the question.  might as well have cleetus and porksword 
give your car a valve job with sand paper and lapping compound.  same 
goes for a sharpening stone / pen, whatever..
you will ruin them much worse then they are now if you even try.  there 
are precise angles, etc etc. you need a lathe, a programmable CNC 
preferrably to even have a shot at doing it right.  You are talking 
measurements of a few thousandths of an inch, and I don't care who you 
are, NOBODY can see that reliably just glancing.
