How to polish in small areas!

[edward soye]

You can masking tape a small strip of emery to the back side of a drill bit or bur depending on size needed and load it into your freedom

When it comes to polishing you can just use cotton ball and rouge on a similar bur...

It takes a bit of patience and time but when it looks amazing it is worth it.

I needed a thin split mandrel once and took a piece of hanger wire and carefully sawed down the center to make my own mandrel. Maybe thats an option?
