Thanks for the replies. I was using the wrong term, I meant a round-over bit, not a cove. I am attaching a couple of pics of my equipment and what I am using.
First, my router with the roundover bit and the fence.
The roundover with out a bearing.
And hard to see, some of the poor cut I got on this piece of pine. The first cut was actually better, but not deep enough to completly round the edge.
I was feeding the wood right to left, with the wood laying flat so the bit was cutting the 3/4 edge, and the 1 1/2 inch face was on the table. Should the wood have been turned the other way? (Tall side against the fence).
