I really enjoyed this thread nauz. I use the watchmaster myself and am constantly scouring online sources and meet-ups for spares and parts. I think I have 3 complete units sitting on the shelf waiting to be called into service but my main WT just will not quit. I have used several brands and styles of cleaners but IMHO these are the best of all.
I regularly clean and spray the dryer cup bushing with silicone but am always worried that the bushing will wear out and I will have a hard time replacing it. Any ideas on that topic?
