I had a stand lying around the house that was perfect for my imitation orrery. When I placed the clock on the stand and put the hard drive platter on there was a bit of a gap. The gap seemed a perfect place to add some gears. Unfortunately, I didn't have any large gears lying around and I didn't know how to make them. I wandered around the aisles of a dollar store and came upon a cheap Spirograph toy which of course had little plastic gears. I painted them gold, I also had to trim a few so that the clock will fit and then glued them to the stand with PVA glue.
