Boring head - video

I watched the video, nice idea for a counter weight low profile design, but I think, he's spinning as if the tool is fixed, and the material is spinning, for his cutting speeds, and using insert carbide, does not mean spin that cutter at it's optimal carbide SFM, even with a counter weight, that did not account for the boring bar mass.
SLOW DOWN.
If you noticed his bores are not so clean of machining, probably no power downfeed as a larger mill would have. Or deflecting from too fast, and then dulled the cutting tip.

He appears to have experience with lathes from a previous life, as he mentions in an earlier video, where he acquired the lathe, and had worked with them 6 years previously. And single point turning a left and right hand thread, without lots of practice, or bad parts, he did darn good. He was expecting a bit much of his thread tolerance, as far as feed accuracy. But nicely filmed.
And I like to see that same machined surfaces, that I make in my own shop vs those off camera polished jewels.

Thanks Jon for posting.
