I see that Bosch has some sort of system for mortising butt hinges for
doors. I'm interested in one that can handle 4 or more hinges at
once, and the individual mortising jigs would preferably be
adjustable. It seems I get a lot of screwy sized custom hinges at
work. Has anyone used this? Are there others that any of you would
recommend? thanks
