I have recently acquired an old Anfim grinder and when I tried to clean out the burrs and inspect them I found I could spin the top collar 180 degrees and no further.
I am wondering if it is cross threaded. The other possibility is that it has a lock pin?
Does anyone have any experience with a jammed top burr carrier? (Im worried if I force it if it will strip the thread. It will take a LOT of force!)
