      All,
      I am very nearsighted (between -6 and -7 in both eyes). With astigmatism. Now, in my late 50's I also have significant nearsightedness.
      I thought a flip up visor - which I could wear with my glasses would be best. I purchased an OptiVisor with a flip-down loupe. But not happy at all with the visual quality.
      I know you get what you pay for in optics. What is the best type of device for someone with old-bad eyes.
      I have never used a regular loupe - but thinking that may be the way to go. Any of you guys (or gals) have a reccomendation?
      -Paul

      I have an acquaintance who is closing his shop due to health after 43 years.  He has a large quantity of parts, stems, crowns, crystals and all the paraphernalia one would accumulate after a long period in the business.  He needs to liquidate his shop.  This isn't a "Hey do you have a __ for a __." kind of post.  We're talking serious stuff here.  Mass quantities.   If you need parts, equipment, etc. for your practice, please let me know.  I will pass along his email contact  to you.  Obviously, this is useful primarily only to those in the U.S. due to shipping costs.  But he has a huge amount of useful goods and is 100 miles South of Atlanta.  PM me if you need something.
       
      Thanks,

      Hi, I have a few bits and pieces, and clocks. And I am very interested in horology tips, conunundrms etc.

      Would it be interesting for this forum to set up a list where we could exchange things like parts and tools?  I happen to have duplicate tools from my lot purchases, and feel that those could be better used. No money involved. Would that be feasible?

    • I was first in my class in hairsprings and have saved many considered "gone" but that one is GONE, and I'm the biggest optimist you'll meet. Even the best old dude from the Vallee de Joux would not even consider it.
    • I lost the driver cannon pinion in my clone 7750. I ordered a Swiss one, before I read that a Swiss one wouldn't work on a Chinese clone. I could not find out why until I received it. So just to let everyone know why it won't work is, the hole is to big on the Swiss one. The gear meshes perfectly though. So if the hole was right size it would work. If anyone knows where to get one for a Chinese clone, please let me know. 
    • HMT on original bracelet, just serviced, looking more original than any I've had from eBay.
    • Interesting..a gimmick to be sure.but it could  give you an idea of amplitude.dim electric  light might act as a strobe.60 hz is a multiple  of 18000 bph.
    • The height adjustment on all double roller rests is iffy at best. Files are like dogs, they might bite end off a sausage or wolf the whole thing down.   With a double roller rest, if it isn't perfectly parallel to the lathe bed you have a tapered square. If it isn't perfectly adjusted for height you have an oversize or undersize square.   With a single roller it's easy. You turn the diameter for the square to the diameter for the winding pinion. You turn the diameter for the front pivot to the square section of the winding square. You don't turn to the length of the winding pinion- just the square. Single roller rest, file until you just hit the pivot diameter. Index, repeat 4x. Now finish the pivot and the rest of the stem. With a single roller you can flip the rest at any time and measure what you're doing if you mistrust the pivot as guide. With a microscope you also see if you are tapering (possible with either single or double roller- there's no panacea) and correct. Your eyes are incredibly accurate for spotting tapers.   I usually cut the thread first, chuck on that and do the rest. Harden, temper, deblue with a bristle brush and white (steel) paste in the lathe holding the stem in a pinvice then clean up the thread and detent slot, burnish the pivot and large diameter that rides the plate/bridge. The brush usually cleans up the file marks on the square plenty. You want a 6 or 8 cut file for that. 8 best for the finish strokes.
