Subject: When do I replace Rocky's burrs
I've searched the group archive ... seen everything from 900 pounds to
100 pounds. Is there a consensus? Does anyone have a good rule of
thumb as to when to replace them? My DL Rocky is about 3 1/2 years
old, and I grind about a pound of coffee every week to 10 days. While
I can't say I've noticed a quality decline, either in the look, or the
feel of the grinds, or the taste of the espresso, of course the
decline would be quite gradual. And for my office, I've recently
gotten a Bodum with a plastic filter. I don't know if it's the Rocky
or the plastic filter/plunger of the Bodum, but it seems I have a lot
more fines in my presspot coffee than when I had a metal-plungered
Bodum.

I aim for about half the rating - so change at 150 if they are rated at
300 - for exactly that reason - they aren't expensive

Based on your usage estimates you are under 180 lbs. Unless abused
rocky burrs should do well to 500 -- 600 lbs.

7 more years or so.

No, but I have a "rule of thumbnail".

Press the flat of your thumbnail gently against a cutting edge of the
burr, and drag the burr along the length of the nail to peel a shaving
off the nail. Does it peel a continuous shaving off with light
pressure? If so, your burrs are still sharp. If not, replace.

Can you suggest a test material that is not part of the human anatomy?

Well, if you don't want to use a fingernail for some reason you could
try an expired credit card, or find a hobby shop that stocks polystyrene
sheets.

To check the condition of any burr set, remove the top burr carrier & 1)
visually inspect both burrs for chips & other damage, 2) drag your thumb
nail over the top burr; if it *digs in* it's still good.
