I took the bearing off my router bit and freehanded the 1/2″ radius. After practicing on scrap, it was not too hard to feel the right bite to the bit. The outcome was very good. Even with that radius, it was one of the more difficult places to get the cloth to lay down, and in the area where I was most concerned about since it isn’t visible and most exposed the environment.
I did both sides at the same time. Not sure one layer would have been any easier to get to lay down. Sure felt good to get that part done!
