Is there a trick to setting up a countwheel strike so that the paddle rests between the star points after the strike? I have taken a Junghans movement apart several times and every time the paddle hangs off the tip of the star wheel at the end of the strike.

Large adjustments are done at the star wheel. Smaller ones are done one wheel up. The star wheel may be one that's a friction fit and can be turned. Willie X

Last Junghans I worked on, it took me 10 times to get the star wheel to stop exactly where I wanted it. And yes, follow Willie X's advice. Once the paddle drops off, it is the upper wheel that must be disengaged and adjusted.

Count wheel strikes don't usually have a star wheel/paddle setup. Can you post pics?

Interesting. When the train stops, see if you can turn the star wheel until the hammer falls. Most are friction fit. I use a screwdriver braced against a pillar. It should take a little pressure to turn, but don't force it too hard if it doesn't want to turn. The pivots will take an amazing amount of pressure against them when mounted but you don't want to break one off.

RR,
How much stroke do you have on the hammer. If more than an inch, adjust the stop a bit. This won't change the lifting tail position much but it does change it.

If you had the count wheel off it may not be positioned where it was originally. If it is a pressed you may be able to just advance or retard the count wheel position so the count blade drops after the hammer falls.

Some are very tight. In fact, so tight that too much pressure is necessary to move the star wheel. Damage can be caused if not careful. I made a special tool from an open end wrench that came with a furniture assembly kit. It’s thin and works well. I just inserted two short pins in each jaw. It allows you to hold the wheel next to star wheel without putting pressure on the adjacent wheel while prying the star wheel.

On the Westminster, you might be able to adjust it with the gathering pallet.
