I watched this a couple years ago. Been more than once I tried to justify making a gear but was always able to find a stock gear I could rework to fix a broken machine.
I'm going to make a couple gears some time real soon just to be able to say I did it.

I want to do that, for the same reason.
Let's see; I could connect my NC rotary table as a fourth axis... This could be easier than using a dividing head. :)

The labor time required - amazing.

Nothing new there for me, but I used to routinely cut clock wheels, and pinions.

It takes less time than you may think. I timed myself making a 144 tooth great wheel for a clock once. Fifteen minutes to cut the teeth with a home made cycloidal cutter. Two hours to cross it out (make spokes), debur and polish. The dividing head was home made.

So, what tidbit did you learn from that video, Winnie?
Man, who was the _dynamic_ narrator?
-- To know what you prefer instead of humbly saying Amen to what the world tells you you ought to prefer, is to have kept your soul alive. -- Robert Louis Stevenson
I wouldn't feel any shame doing it that way if I could. :)

Sector arms. I'd seen them on dividing heads before but never knew their purpose. Kewl.
And mostly just seeing the tools assembled and in use to create the gear. One picture being worth a thousand words and all that. Edifying while entertaining.
Hey I understood everything he said!
I took a computer architecture course at DEC many years ago. Our instructor had an almost opaque accent and would sneeze occasionally. It took me a couple hours to figure out that he wasn't sneezing, he was attempting to say 'Master Sync, Slave Sync'!

I think that it is a beautiful video. I also loved the music. Sounds lie it is from old silent movies, Would anyone know what is the music.
iFor gears and many other interesting ideas, see if you can find the locations of John Stevenson's shop methods.
A few (or more) years ago, he built a gear cutting machine using synchronized steppers and a worm gear box instead of a dividing head.
I can't name it but it falls into the category of music called 'Honky Tonk' or 'Boogie Woogie'. Prolly a rag of some sort.
Very nice!

YES! Thanks. --Winston
I think I prefer Winifred Atwell's rendition :-)

I couldn't listen to the YouTube version because it was very poorly recorded. Atwell appears to be a genius, though. Made it look trivial.
