Discuss roast levels and profiles for espresso, equipment for roasting coffee.
Got a squeak the other day but dropped some mineral oil on the shaft and it stopped. I had done 2 teardown and re-greasings, so I'm hoping that takes care of it. I'm pretty sure a bean got caught somewhere after the 2nd teardown, but it seems to have worked its way out. I also got some weird rhythmic/rotational noise the other day, closer to a low groan than a squeak though. I'm doing 1 roast once a week at this point, so not really putting a ton of time on it; I think I'm on roast 26 now and all's well.
Through hard work, victory!
