IMO Best advice repeated many times above is don’t.
If you have a cylinder exactly the same diameter as the ramp section when the cylinder is wrapped with 2000 wet-or-dry and are very, very careful you will probably not do much damage. One of the many problems with the Dremel tool wheel is that it is not the same size/shape as the ramp.
You are very likely to change the angle or the radius of the ramp, both very ill advised.
A mirror polish looks nice but really doesn’t change the feeding.
