Routers

How can I cut dadoes with smooth, even bottoms using my tablesaw dado set? My set leaves ridges even though I just had it sharpened.

I get burn marks when rounding over the ends of glued-up cutting boards. I thought I was moving the trim router fast enough, and the bit is sharp and clean, so why does the wood scorch?

How can I rout a groove to accept the bottom panel in a small box-jointed box without exposing the unsightly groove on the outside of the box?
