Some time back someone posted a link to a video showing a chap drilling
a hole in a thin brass bar in a lathe.
Iirc he used a chaser to make a cone-shaped cut in the end of the bar,
then used a drill held in his fingers to make the hole. It was a very
small lathe, probably a watchmaker's.
Anyone remember this, and have a link to the video?
Update, it's Drilling an Orifice on the Lathe. but sadly it doesn't seem to be available - there's a message on youtube saying it's a private video, whatever that means.
Why I'm asking is it's an example of axis-following in drilling - the drill follows the axis of rotation of the part (the part is rotated, not the drill). Anyone have any similar links?
Another question, can a drill be "steered" and if so how?
Thanks,
