Hey if this question is still open, I have very personal recent experiance with this subject mater. I just made my own flooring for my kitchen. The first thing I would like to say is that it takes a lot of time to make it yourself in a home shop. I would not take one suggestion that said do it with a hand router. Use a router table at the very least. As far as sanding it smooth first, it isn't neccesary if your planer doesn't have snipes. I planed, sanded with drum sander and after installing, it still needed sanded. No matter what, there is always some sort of mis-match. The one thing I can say, is that I won't make my own again. Way too much work involved. Around here good flooring is as cheap as $2.00 a sq ft. After taking the time to make and install, even more expensive flooring would be worth it. I have a professonal coming in Monday to sand and then I'll finish the rest. If I can figure how to post a pic, I will. If I can answer any other question please feel free to ask. Oh, and it doesn't need felt backing if you have a basement under it. It does need to be glued as well as nailed.
