Any pros or renovators out there have a strong recommendation for a particular brand of hinge mortise jig? I mainly use the 4" hinges with a radius edge that come standard on most pre-hung passage doors these days. When I renovate houses we typically change all of the doors. I would like to make the process of replacing doors quicker and easier. Any thoughts? I'm not really interested in making my own plywood templates for each situation. I would like something that is accurate and will move from jamb to door without shifting or moving around on me. I threw out all of my old copies of Fine Homebuilding a couple months ago in the great house purge of '13 so no help there.thanks,Charlie
