Lew: Thanks - that is reasonably straightforward in contrast to some of the other literature I found on the web. John. |

No need to move this thread at all! I'm interested in reading how you progress, and sorry I have no clock knowledge to help with. Raynerd would be able too if he checks in. I'm sure there are others. Nice photos! :beer: |

The first quarter chimes the 30 tooth gear rotates once , half hour rotates twice three quarter three times and four on the hour , I have two similar clocks will have a count . |

Jeff: I would really appreciate it if you are able to make a count. I agree (with no knowledge to back this up) that 60 teeth make more sense than 59. In the meantime - not having done this before I figured that making a 59 hole plate would be interesting - I made this: I didn't have any suitable aluminium but had quite a bit of very nice 12 mm marine ply (lots of smaller scraps). It's approximately 7 1/16 in (18 cm) in diameter. If nothing else perhaps I can integrate it into some type of wind chime. I cannot source cz120 or anything similar nearby so have decided to use regular brass for a test run. Bought a 6 in. piece of 1 3/4 in. brass yesterday (after taking out a second mortgage) :med: Told my daughter that it would be left to her as part of my estate. Once I make a suitable gear I will source the proper material and make another. Steve - thanks for looking at this. Pretty small compared to your lathe project. John. |

I think Mike's Workshop might have info on making gear cutting tool bits using taper drills. There was an old ME series on doing it with two disk buttons you make -- which was cool, but the taper drill method built on that method and and seemed even cooler. Then, there's the Gingery method of just grinding to shape by comparison with similar teeth. And probably a million others. Ivan Law's book is always highly recommended by people. |
