Subject: Some q's about a new to me RR45
 

Hello all. Long time lurker and review reader, first time posting.

I recently bought a Grindmaster 625(RR45) in fairly excellent condition for $120 shipped on eBay. The hopper is trash, and I don't need it anyway. The burrs look almost brand new, and it was fairly clean for a commercial grinder. I believe it has been serviced recently. I think I love it!

One problem. The doser seems to drop the grinds off center, lots of grinds to the left of the portafilter. Is there an adjustment of the bottom cover for that? So far, that seems to be it's only limitation.

Second, after cleaning, I have run about a half a pound of cheap beans through it, in various adjustments from turkish like dust to press pot size. I am getting a Cezve in a few days, and I am worried about getting burr metal in the coffee at that fine a grind on new burrs. Should this be a concern? Any break in recommendations? I can get decent whole bean for $4 a pound, so if I need to I'll run more.

TIA

this is standard doser behavior.  all of them "throw to the left".  If you have a bottomless pf it helps, because you can slide the pf towards the left to play catch with the doser..

Everything I've read about new burr break-in pretty much says run 2-3# through them.  Funny you bring this up, because I just replaced the burrs on my older Macap M4 earlier today.  I ran about 2 pounds through them, then plowed through a 12oz bag of great beans re-dialing in the grind.  I was able to finish the bag with two great doubles though. If I were you, I'd go get another pound at $4 and run it through.

Thanks. Will run another pound through. I hate to waste coffee, but at least it won't be my home roasted. lol

Don't think of it as wasting coffee, think of it as community service as you are removing yet a few more pounds of stale, poor quality and good for only mulching "coffee beans" from the world

Normally I'd agree. But this is Armenian coffee from an International grocery. Freshly roasted(generally) and not bad. It just happens to also be inexpensive as well. But yea, I get it. lol

in principle you might get some metal shavings during "breack in", but need not worry : metal parts are not soluble.....so they won't get brewed...

True, but in Turkish coffee the grounds are not filtered. True, most of the grounds stay at the bottom of the Cezve or the cup, but still. I found a neighbor who gladly took the ground coffee off my hands, and didn't care that I had used it to break in the burrs.

I ended up finding a 'Automatic' adjustment ring. The type with 80+ steps. It was $18 shipped for the rind and the pin. Sweet! The ring is cracked a bit, but I believe I can repair it. I guess I can always index the crack so that it does not interfere with where I am grinding at, but it is a heck of a lot cheaper than $40 plus Aussie shipping, as I have not found a US supplier that has one. I can always buy a new ring later, and the pin shipped for $18 is still not that expensive.

Where did you find an 80 pin ring (or was it used?).  I'm looking around for similar for my cc45.  One hint with these grinders is to use teflon tape to keep the upper burr carrier a bit less sloppy.

It was definitely used(at that price). There are a couple of suppliers in Aus that have them: Click Here (www.aetcoffeeparts.com.au) and  http://www.coffeeparts.com.au/ginorossi/702053 . The shipping with the sencond link was excessive. Good luck!
