Thread: My Wooden geared clock

Dean
Only had a quick look at your cad program (modella player 4)can you not create a new tool or change a existing one to a new diameter?

Russell

Re the yoke
My clock that I build runs with out one ok
still do not get the advantage or disadvantage of having one... google it can not find anything

Russell

You right! just checked Modella and you can add a new tool with a diametrer in the .1mm increments!. Amazing have used this prog for years and never realised! Obviously didnt need it..but its useful to know.

A quick update...finished the 3 piece ratchet gear. Turned out a treat.


The finished gear runs true and hopefully will withstand winding the 10kgs day after day.
Have started on my final gear! I managed to complete 4 of the six pieces this week; hopefully if time permits I will have time to finish the two pauls as well. Now where thats beer!

Hi all,
I have spent the last week cutting out the blanks to form my final 60 Tooth gear. I have never done a 6 piece gear before but should go well. The new gear will hold the double paul design. So far so good. These take forever as each piece has to be checked against the piece thats next to it before its removed from the CNC. The pic shows the 6 individual pieces prior to gluing. The fit is so tight that I am afraid to apply glue untill I press each piece half way together. Today I used a large offset metal vice to press each piece together., removing the excess glue each time. The last 60T gear I remembered I resorted to using a lump hammer!. I found the vice quick and I felt I was less likely to snap one of those joints off in the process. From experiece I like to have a straight run as my final join. It was a stressfull process as there is no return if anything goes wrong I would have to start over again.




Thank God that part is over!.

Tomorrow I will drum sand the blank flat and then its onto the CNC.

Dean.

Dean you are true professional in your work
Every time I see that join I just go WOW.


Russell

Hi all
Here is my newly designed 60T gear. Before I finally commit to the new design I realised tonight that I will have to trim the new pauls so that they dont interfere with each other. By doing so will I be loosing any strength in the pauls? I will also need to add some onto the end of the pauls so that they mesh with the ratchet teeth properly. What do you think Russell or anyone else?
cheers

Dean.

Dean
The pauls is a poor design I will have a go at a new one for you.
The ratchet arm should be straight from the tooth to the pivot point the paul.

Russell

Dean
Here is my attempt.
If you want to have a go using it, I will email you the shape ok
I think you might have to thin the spring part of the pauls if it is to hard to turn the ratchet wheel, but try it and see.
Russell

Hi Russell, can you send me the pauls design you did? That would be great.I want to play with it tonight and hopefully cut a prototype tomorrow.

cheers

Dean.

done

Hi all here is todays progress in pictures...
Just before sanding

From behind just before liberation (when everthing drops out)

Some very fine remenents

The final sand using the inner bits as a jig to hold the gear still


will post the final gear tomorrow

Dean.

Hi all here is the finished gear.





I took particular care to make the trisoloc design exit between the teeth rather than through the middle. Just finished a prototype paul so hopefully by the end of the day will have some more progress to report on.

cheers

Dean.
