Several hours of cleaning and last minute wet sanding of scratches wore me out. I washed all the pieces and epoxied the ears and eyes in the head. Also put a fresh coat of primer on the head.
I also glued the pistons in the outer position as suggested by Chris. By the time I got all this done, I decided to wait an extra day before boxing him up.
In other robot news ... looks like there's going to be a robot convention at a super location in Florida after all. Keep the end of January 2007 free. Details when I return from vacation.
