DIY gear hobbing attachment for milling machine

AndysMachines: Digitally (PIC chip) controlled synchronization between hob and gear blank, Pt 1:

Oh, good grief! I am five minutes into the video and I can plainly see that we are going to have to watch it being made, piece-by-piece. With absolutely no explanation of what the design theory behind it is or what is going on.

AAAAAAAAHAG!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1111

I would like to know what the hole saw is?

Sorry Paul, for not informing about the non-informative, tedious and perhaps non-pedagogic process beforehand.
That said, I personally like following the machining sometimes just to see what decisions is being made when,
and try to figure out the ideas and methods used. For instance: Not a single carbide insert, "merely" HSS lathe tools used throughout.
I'm also biased in having some interest in DIY hobbing, and learned quite a few bits from it.
But then that's just me - and "to each his own" I guess...

Ralphxyz: Seems to be a run-of-the mill Sandvik HSS 60 mm OD hole saw*:

The video must have been speeded up cause that run-of-the mill Sandvik HSS 60 mm OD hole saw cut through the steel like butter.

Yup- the shot was indeed speeded up as well as cut/ POV changed three times.

A PIC chip? Andy from Andy's Machines must be a pensioner.

All kidding aside Andy's Machines is a pretty cool channel. He builds lots of really cool stuff. The Terminator eyes video is pretty neat.

Caution: NO drawings, sparse comments, some machining that might be disturbing to sensitive watchers.
Watching this video is NOT MANDATORY.

Hey Nova. Might you have a more specific URL for Andy's Machines? Did the Google thing and all I got was professional business machine shops. Didn't seem to be what I was looking for.

PS Great job Swede!!!

Here you go. This is the Terminator eye build. It's purely artistic, but still very neat. He makes a working mechanical iris.
