Well okay, call me a greenback in router terms if you wish, but.....
I have always thought that despite the power the router can deliver there was a de facto limit on the amount of cut that can be taken in a single pass.
Reason is twofold. Firstly, when the router bit chomps some material it has to dispose of it by chucking it sideways. Surely there is a limit beyond which it isn't possible to take off more material?
Secondly, router cutters in motion against material generate heat. I would have thought that if you tried to dispose of too much material in one go then the bit wouldn't be able to transfer the heat, so it would get hot.
Am I talking thru my defacation device?
