Great job!
As for the Sumbeam logo on the front I vote for white, would make a nice accent.
I'm on the hunt for a mixmaster and may redo it in yellow, you gave me the push I needed to mentally commit to it. Could you elaborate on what you did to the rotor? I've read of others putting it in a drill and what - lightly sanding? I've never worked much with motors, electronics is more my thing so this will be a learning experience.
Now, if the eBay seller I bought from actually ships my mixer I'd be all set, but I have a hunch I'll have to file a claim...
