Installed the Versa-Vise and while making brass brass jaws for it , had to keep tightening the 2 hand knobs. ...don't hold very well. Decided to drill detents for both knobs so the rotation and tilt will stay put. I don't intend to use either adjustment, but do want the vise to stay put. This is a secondary vise for holding small parts while my big vise is in use and isn't suitable for my heavy hand while roughing. Anybody use this vise for their main vise and did you make any changes to stabilize ?....Fred
