Minimal Clockmaking

[Brian]

Hi Tom
Its just a different sense of reality, we get the same comments from the family back home in Scotland . also its partially my wicked sense of humor.
We think its cold!! but the houses have plastic water tanks on the roof???
Hi Dave
Start by cutting just two teeth gradually increasing the depth until the profiles just meet at the tip of the tooth.
This is then the setting you require to cut all the remaining teeth
Just slash thro the blank in one cut --Index--cut--
I hope this helps Brian.

Brian,
I'm not too sure where the 80 tooth gear comes in, to cut a 32 gear tooth

Dave
The 80 is mounted on the rear end of the spindle to index the chuck. Divide 80/32 = 2 -1/2

index every 2-1/2 teeth on the 80 gear and cut 32 teeth on the new gear.

Now you know why a book is going to be required at the end of all this.

Brian.

A BIG thanks to you Dave, the questions help me to see how I need to explain things.
As we say No such thing as a silly question.
Being silent, when you don't understand, is really silly.

Brian,
Yep, your right, and of course I like to know what's going on

The next gear is the largest 80 teeth. but it took only 45 Min's to cut.
The plastic clamp is to stop the gear ringing

   

   

Only 2 more to do.

Hay Brian,
I know little about clocks other than what there for, so question are clocks gears normally a stamped product or mostly still machined ?

I'ts amazing what don't know when I stop and think about it!

Hi Jerry
A very good question but one I am very ill equipped to answer.
The world has changed over the past few years, the days of the cheap tin alarm clock have long gone.
Clocks and watches now seem to be polarized into --Digital--Quartz--(plastic) and real
movements that are either hand made (custom), or turned out by CNC.
I am sure a few cross these boundaries, but I think the days of pressings have passed.I am quite happy to be proved wrong if anyone has better knowledge on the subject.

The last two gears ready for crossing out and polishing.
That's all the gears, and the little home made cutter is as sharp as when I started. Just goes to show that you don't have to spend money!!!
