Sir, I like your style! On another note, I watched the video were you fixed some of the collets where the grooves weren't deep enough. You used an endmill bit to mill away the sides of the registration insert, so I was wondering why you decided to mill the plate sides with the tip of the bit (the part where you talk about vibration) rather than laying the plate flat into the vice. Was the vice to small? 🙂
Thanks for the comment. The vise was big enough. When I Tried laying it flat, the back of the vise stopped against the column before I would have been able to make the entire pass. I thought about moving the rear vise jaw to the back of the vise. That would have worked, but since I was working with a thin plate and not really taking much material off, I decided to try it with a backer against the plate instead.
