For instance...recently I was trying to use the router to cut mortises for hinges. Yes, I could have used chisels, but I thought I'd try using the MFK 700 for the job to make it quick and easy. I cut close to the lines with the router, then just clean up with chisels. Thing is, with the MFK, you can't see the lines. If the bit area of the router were open and visible, this would have been possible.
