I am going to try a flap sanding wheel (80grit) on a dremel tool for the next piece. They sell for about $8. It seems like it will lend itself better to "feeling" and seeing what your doing. Read the thread on the other forum about "Polishing contoured surfaces" and see how the guy describes the "feel' in postGeneral Woodworking.
When I get the flap wheel mastered, I'll graduate to the next level, working my way up the amperage chain. Pretty soon, 15 amp, 2-1/4 HP ANGLE GRINDER shaving off a few 1/10,000th of an inch with the precision of a surgeon...boy it'll be a thing of beauty!!
I scratched the idea of using the flap sanding wheel for the dremel tool. The more I thought about paying $8 for the thing, and having only two grit choices, 80 and 120grit, I decided to use the sandpaper and equipment I already had. I decided to give my Ryobi random orbital a try. The 100% hand sanding method I used prior HAD TO GO. Took too long and was too tedious.
Here is the setup I came up with to hold the Ryobi so that I could control with work piece with two hands.

I put the mirror and sandpaper up on a 2”x 3” so that I could rotate the part without the “wings” hitting. I rubbed the part against the sandpaper which stayed down of the 2” x 3”. That was the best way to keep it true.
Using the sander to get through the surface pits saved a boatload of time. Instead of it taking 4 hours to complete 1 piece through the buffing process, I was able to do 2 pieces in 2 hours. Just a couple pieces more to go and I am done. Here’s the finished feed stop knob. You'll notice a little divot on the top of the right wing, near the OD. My sander slipped in the vise. Bummer but I’ll live with it. Driving by 60 miles per hour, you’ll never notice it!! Well, that's it for polishing pics. You seen one, you've seen 'em all.
p.s. Use good quality sandpaper. It makes a difference. I had purchase some odd brand from Harbor Freight, real cheap, and it was exactly that…….REAL CHEAP. It just didn’t hold up. I would go through it twice as fast as the good stuff. Stick with name brand (i.e. Norton, 3M etc.)
