I managed to get some snaps and make a little more progress :ddb:, although a step back at the same time :palm:

Here is the wheel mounted on the clock:

I then started the count wheel arbor:

I didn`t get any photos of burnishing the pivots on the wheel, so here is my simple setup I used. This was actually on the count wheel pawl pivots

Here is the count pawl and pivot

...and then with the bracket, please bear in mind it all needs polishing. Notce that the side frames are also pinned to keep the pivot holes aligned.

.....it all mounted :ddb: :ddb: It worked so well! I obviously had to hold a back stop but the pendulum "counted" the wheel teeth!!

I did say some bad news :bang: that being that my deep tooth is too deep and the angle of the tooth too steep so that the pawl gets stuck when it drops into it. I`m a bit dissapointed but things look like they are going to work OK !

Hi Chris,

It certainly looks like clockwork. Shame about the one deep gap between two teeth. Could you attach a tiny "roof" to the pawl, which would drop into contact with the crest of the adjacent tooth before the pawl goes too far down the offending gap?

raynerd:
Hi Andy, just to be clear but I think you do understand, one of the gaps is intentially deeper than the rest. This is to allow the pawl to drop down further once a revolution and engage a "lever" which kicks into motion the impulse module. I don`t know if there is much I can do. I can try and reduce the slope but this will reduce the tooth depth on the other side. I think however, this may be OK as the backstop will still catch it. I could try something as you have suggested, but with 1/32" wire, I expect this will be harder than building a new wheel. I don`t know, something to think about. :bang:

:clap: :clap: :clap: :clap: :clap: :clap: :bugeye: nice going Chris :thumbup: looks like a clock to me :med:

So thats what the widget you had in the drill chuck is used for :dremel:

Yea, its a poor mans Jocots tool!! :lol: It worked just fine and allows you to really push down hard on the little 1mm dia pivot for burnishing without snapping. The brass split collet also made life easier for cutting down the little pivot.
