I can tell you that mine sounds nothing like that, quite the opposite, mine is quite quiet and a whole lot smoother than his. I don't know why he has the feet upside down, maybe to bolt it to the stand but really you don't need that. Mine sits on the bench and like I said, vibration free.
Interesting, I'll try to keep track, but mine is set up for mostly fret work on 1/8 inch stock. But I've also upgraded the blade holders to the Pegas, that helped quite a bit also.
