Al, lowering the fork increases fluttering, because the resistance to turning the fork is reduced and that makes it easier for the escape teeth to bounce off the pallets, followed by fluttering. Here's the rule: Raising the fork reduces flutter, increases pendulum rotation, decreases overswing.
Having successfully resurrected a Kieninger Obergfell Kundo clock, I'm wondering what the term fluttering means. Mine still runs a wee bit fast, and I have a handle on how to adjust it, but what's this mean? Duane
No, the minute hand being loose does not cause flutter. If the pallets and anchor haven't been fiddled with, one can raise the fork a little to stop the flutter. You want it set right at the edge of fluttering. Do note that it is normal for these clocks to flutter sometimes while advancing the minute hand but should stop as soon as the pressure is off the minute hand. If someone has mess with ...
I have a Schatz '53 mini 400-day that I just replaced the suspension wire. It ran for 5 minutes, then stopped. So I lowered the fork, which allowed the unit to run for 10-15 minutes. Then I lowered it some more, and then got a lot of flutter, so I stepped back to the previous setting. I have...
This locks the escape wheel and prevents the fluttering. Kurt Working on anniversary clocks is the definition of insanity...doing the same thing over and over but expecting different results!
Do you have a problem with the escapement "fluttering"? This can be caused by the fork being too low on the suspension spring giving too much "flex" in the suspension spring between the fork and the top chops (block) of the suspension spring. Best way to determine this is to test the clock on a shelf where you can observe it for a period of time.
