Ron, when I was building a new home in the vicinity of several lumber mills in timber country, I was advised against using a router to make flooring from red oak planks.
To prove his point, one mill superintendent showed me the machinery he used to make flooring commercially. Large, specialized shapers. 3-phase motors. Flooring needs profiles on both ends. And on both sides. But most importantly, you need to grooves cut on the underside to prevent bowing and cupping due to floor moisture. Look at a piece of prefinished flooring at Home Depot. The kind that is factory sprayed. Flooring doesn't just sit there. It has a job to do.
First off, aside from all the various cutters, you would need a power feeder to run all those board feet through the machine. We had need for about 800 linear feet for my house, and that would have entailed processing 4000 linear feet of wood edges and faces. Cutters would break down if your arms didn't fall off first. It would not be fun. And I could have bought the raw cut timber for less than $1/ft.
And do you have a cyclone dust collection system? Some jobs are best left to the big boys, and in this case, that means a shaper with good DC, and a Power Feed.
