I Googled "EB 8201" (site:watchrepairtalk.com EB 2801) but nothing came up. Can you please provide a link? I don't even know what an "EB 8201" is.
And while on the topic of links; as a service to my fellow members, I always try to include a link when I make a reference to something I've read or created on the WRT or elsewhere so that they don't have to spend their precious time on trying to find something that cost me so little to provide. And, it makes me feel good!
I must say, that's sounds like a pretty interesting idea. I will definitely try it. Thanks! Unfortunately, that will make me click a "buy button" or two as I'll be needing a spirit lamp and some methanol. I guess my "good repairer/watchmaker" score will take a hit, but if I can get that GR spring to work in my Orient it'll be worth it .
I tried something new with my 70 year old Elma cleaner yesterday. As always, I use Elma Red 1:9 (ammoniated) for about six minutes, then rinse in deionised water for about 2 minutes, and a finally rinse in Suprol Pro (really nasty stuff) for about 2 minutes. However, this time around, as I was just cleaning a mainspring, its barrel, lid, and arbor, I ran the motor as hard as I could. This made the Elma Red look like pink milk, but the result was pretty amazing. I've always run the motor pretty moderately for fear of destroying the hairspring but the results have just been so so, requiring quite a bit of after cleaning. The next time around I will "put the pedal to the metal" and see how it goes
EDIT: When using water based cleaning solutions (like the ones I describe in the above paragraph), be very careful not to overdo it. The first time I tried my Elma machine I ran it for something like 40 minutes, and the entire movement got stained and even some rust started to develop. It took me a day of manual cleaning and polishing to get everything in acceptable order
