I have a big beam of white oak I need to cut 2 1/2” deep by 1 1/16” wide dadoes in. I could get started with a track saw and clear out the bulk of the waste that way. I’ve found router bits online with that cutting depth. How do you feel about that much cutter poking out the bottom of your 3 1/4HP router? I’d need to max out the cutting depth so I suppose a template bushing won’t work. I can’t find a top bearing bit that’s long enough. I’d probably have to clamp a guide for the router to ride against. Is this crazy? Is there a better way?
