speed reduction gear, the start

Here are the three gears for my speed reduction box. The gear on the left is the drive gear that powers the other two. The middle gear uses a second nanotube as a bushing. The largest is the output gear that, hopefully, will drive a couple other CNT shafts. The drive and output gears will pass through the gear box casing, and the bushing for the middle gear will attach to the casing wall. I might need to make the bushing a little smaller in diameter and extend the output gear a little. I was able to set up a second computer today, so I had parts cooking in a couple pots. More to come...
