    It works very well, here is a photo of the grinding process on the 9/16" broach

    Thank you for the detail of the broach. 3.8 thou per side clearance seems to be a fine fit to me, considering a slight radius on the corners of the vice screw head. Broaching always seemed to be a bit of a black art to me but all makes sense when the details are known. It just shows how a goodly amount of thinking can go into a simple handle design that some people would just take for granted. Pretty sure your little finger forgot more than most know.

    Thanks again for sharing your knowledge and experience.
