Step 8Final Polishing...and Make a Movie!
For best looks, sanding and polishing can be done with various grades of sandpaper from 150 to 600 if the scratches are deep, or use a ScotchGard-type pad if there are no deep scratches. Metal polish can be used for a shiny look. A Dremel tool is nice for buffing.
Make sure that the copper wire contact surfaces, at the battery and commutator, are as smooth as possible.
A cool final touch is to find a nice box to fit the parts of the Homopolar Hearts, so they won't get out of adjustment or lost...and to present to your loved one as a gift!
Finally, make a movie for the rest of the world to see...then have me post it here!
