Have been using this unit for maybe 15-years. Every time I need to change sizing dies, I use a channel lock to loosen the lock ring from the external threads on the bottom of the die. I once asked someone at Saeco if they made a thin hex nut as a replacement. All they said was just use finger pressure to tighten or loosen the lock ring. I tried that but the accumulation of lube in the threads of the die body and lock ring prevent my feeble efforts to loosen things.
Does anyone make a thin hex nut with female threads that fit the Saeco sizing die? Use of an open end wrench should be more user friendly than constant manuvering of channel,locks.
Thanks!
