Sure do…that was definitely a bad day for you. Sorry to hear it’s still dragging on.
Yep, I guess covering a hairspring with sawdust does sound kind of crazy doesn’t it? It really does work great though. Boxwood sawdust is used because of its lack of resins. It blows off of the hairspring very easily with a tiny stream of air.
You may know more than you think …I’ve actually had some success soaking hairsprings in acetone that were really gunky when watch cleaning solutions and one dip wouldn’t cut through it. I haven’t tried a fine paint brush yet though.
Sure hope you get some new wheels soon Clam71,
