Subject: grinder repair?
 

(I have a Cunhill Full Metal Espresso grinder (Click Here (www.gavina.com)) that I got for 20 bucks from some guy cleaning up an old donut shop.  It is a monster, two feet tall and weighs a ton. It was spraying coffee all over the place, so I opened it up and found a couple of small holes in the shroud that covers the grinding burs and channels the coffee into the doser. Some black epoxy putty fixed that problem, but now I can not get the grind fine enough to make a really good espresso.

I adjust the burs down to where they touch and then back off untill they are no longer rubbing against eachother, but the grind is not quite espresso, at least not fine enough to create a quality shot with good crema.

Do I need new burs? Is this thing beyond fixing? Is it possible to get these burs sharpened? Any other advice or knowelege of this grinder?

I would assume you need new burrs if you got it for 20$.
