Step 5: Polish the edges
Since the sanded cut will be brighter than the treated wood, you have to use a polishing bit to get it darker again. I used a bit of beeswax and the polishing bit to polish the big opening. Since the polishing bit is too wide to polish the small openings, I cut a Q-tip (cotton bud) in half and mounted it on the Dremel. Applying a bit of wax you can now easily reach the small openings.
