Hi guys. Thank you. CIM does look like a good option. I have never used gears as I am very new to this stuff so have a few questions that may seem silly.

1) Where do you actually buy them from? Do you have to buy them individually or do you buy them in a pack?

2) The CIM motor in the link looks like it has a shaft that would need an 8mm shaft hub attachment. Similar to question 1 where would you get a hub that is a gear thing?

3) Really silly question now. With gears (and for example in the picture Lucy sent above) what do you use to join the two pieces of plastic together and what metal bars do the gears go onto?
