Re: The next project

Hi,

I read this thread and all I can say it is marvellous. I did some clock making long time ago but most jobs were done with proper tools. Here, however, I found many of the classic ideas from my clock making books turned into reality. Very, very nice thing to find.

How is the clock build going? This project deserves special respect from me.

Re: The next project

...this has 32 teeth so i used the 80 tooth change wheel to do the indexing.

How do you use an 80 tooth gear to index 32 positions? Every other tooth gives 40, every third gives 26.667. What am I missing?

Hi Mark

80/ 32= 2.5 index every 2 1/2 teeth.
I dont think you missed anything, just went down not up, think of it as a 160 t gear.

OK, Glad to help) Brian.

..index every 2 1/2 teeth...

Ah, I didn't know it was fair to index at the top of a tooth. That makes perfect sense. Does your index pawl lock in that position as well?

Thanks for the reply!

Re: The next project

I used 2 pawls the second one is adjustable to get exactly 1/2 a tooth.

Now you can see why i am doing a instruction book for this clock over 100 photos taken so far and 15 drawings done , and a long way to go yet.

Every question asked helps me see how to construct the book.

Thanks, Brian.

That is pretty cleaver! Your thread is VERY interesting; and, I'll be watching it very closely. You might get tired of me prodding you.

It will be a treat to see the finished clock and the book. More power to you! I plan to goad you onward.
