No it's not 52. I had looked at the Pocket Watch lift angles thread, which lists Elgin 6s as something really high like 62° but visually that is not at all what this watch is doing. I think 42° is more correct and that's where my machine is setup. The watch has a million problems but I have made solid progress. Impulse jewel replaced. Hairspring didn't match the balance (which also doesn't match the serial) but I got it down into range this weekend with 8 or 10 huge timing washers. Replaced the mainspring, balance and train are nice and free. At this point it is running consistently and in beat at about 160°, the third wheel has a bend that sends the timegrapher on a little roller coaster every 8 minutes or so. Remaining amplitude problems may be down to the escapement. The banking pins were way out and it didn't run at all before I started. It has one of the old brass escape wheels rather than steel, and I assume the faces its teeth are probably worn or scored in a way I can't yet fix (or see without a microscope). I know this watch is not going to run above 250° but I am going to keep trying to get above 200. But the best part about this watch? Some unscrupulous person stamped "21 JEWELS" on the train bridge sometime in the past, right on top of the Damascening. It's a 15 jewel movement. -
I think it would rather be the blast of high current drain that would do the damage. But if used occasionally to maybe fix a mainspring or do dial feet it might be worth trying especially if the mainspring or a replacement couldn’t be found. Tom -

Hello Mark, thank you for the ad removal , like JohnR725 , I appreciate any revenue from such would be helpful. This is the one forum which encourages conversation and social interaction and in that sense it is unique All the others I frequent can be a little intimidating and answers some what terse some quite rude. I think on here we try to do justice to your site in keeping with your principals. In my opinion it is like no other. The contributors behave and act like gentlemen and ladies. And long may it continue to be so. -

The high voltage will take a toll on the battery but if used occasionally such a the proposed bridle welding I guess if it works it’s worth the price of a battery.
