I really appreciate all of the answers I get from all of you guys to my questions. Well here is another query of mine. The question I have is about the router round over bit. How do you know which one to use on X size stock. The smallest stuff I work with is 1/4" and the largest being 3/4" thickness that is. I may be able to answer my own question but read on. I'm looking in the Rockler catalog at the round over bits and they have several different Radius Height Shank. I get the shank part thats what goes inside of the router but the height and Radius kinda have me a little confused. Say I want to put a round over edge on a 3/4" piece of Red Oak. Should I go with the 3/8" height bit or the 3/4" one? I've never really used a router before but like once or twice to mortise for a hinge or two. I've always used my belt sander to put a round edge on my stuff. Sorry for the long read.
