Welcome to the forum.
Please tell us a little more of your project. How many pieces do you want to process ? Are you going to turn them on a lathe after you do the roundover ?
This very valid question has yet to be answered and thus we are left to speculate.
Back when I was doing a lot of turning for others and I'd get a baluster job, I'd use a make shift router table to round over the edges in the middle of a stick. This significantly reduced the vibration of the roughing out process and made things a lot smoother on the hands when using the left hand as a steady to get a rounded steady rest area.
I don't have photos of my router setup because it was little more than a long piece of plywood with a router stuck under the middle. It was really helpful and made a spindle job go much quicker and easier.
