First off, thank you all for your comments. I am learning a lot. The accuracy I am concerned with is that of the setup. How accurate does the setup have to be to get rid of the ridges that remain after I turn the work piece to diameter.
The attached photos will (I hope) show the ridges. The process I am using is: 1. Set the bit height, 2. start at the tail end, 3. place the center of the bit about 1/2" to the rear of the center of the cylinder, 4. router carriage fixed, 5. rotate the work piece 1 revolution. 6. Move router abour 5/8" to the right 7. Repeat steps 5 and 6 until reaching the head end of the work piece. The ridges can easily be felt and are not just a bit of fuzz. They don't sand off very well at all.
