Round-over double trouble!!

Welcome to the forum.

thank you old 56

I was going to say a bull nose bit but only realized this because of our recent trip to the countertop shops....

A bull nose bit of the correct size, or a quarter round bit also of the correct size for the radius of the edge on the piece that you are trying to match will do the job, but you will need to rely on the router table fence and not the end bearing when using the quarter round bit on the second side, or there will be a step in the center, caused by the bearing riding on the curve left by the pass on the opposite side. It's best to use a router table fence for both passes and both bits. Your attachment shows that you are not using the correct bit to achieve the full radius that you are seeking.

Ditto what @CharleyL said, and he is far more experienced than I am.

This Rockler link has a chart that shows the different dimensions of a round over bit, it sounds like the "R" of your bit isn't 1/2".

This is less expensive, I've had good luck with both CMT bits and ordering from Router Bit World.

Hi all have some window stools to make. Originals are 1" actual wood.

My issue s I'm using a 1/2" qtr round and my profile looks like below.

So mine looks like the send one in the pic.

One inch thick board, use a half inch roundover. Set the fence even with the bearing on the bottom by spanning the gap in your fence with a rule and then move the fence to snug the rule against the bearing. Lock or clamp the fence down then rout one edge, flip it over and rout the second edge. A bullnose bit would do the full round in one pass, but it's not necessary. If you want the second profile, use a quarter inch roundover exactly the same way.
