			Minimum teeth count for a spur gear should be 12; maximum ratio of a pair is 1:5. ([http://www.physicsforums.com/showthread.php?t=704162 source). [https://www.youtube.com/watch?v=8bml2pK6Ra0 Spur Gear Design Video].

			== Spur gears ==

			I didn't see anything on the wiki about the pros/cons of cutting our own spur gears. The advantage of this would be a reduced size of the module. I don't have any resources on the stress calculations involved in that operation. I assume off-the-shelf roller chain and sprockets would be stronger than spur gears that we make ourselves, but I am only assuming.
			Basic process:
			*Make an involute cutting tool on a lathe
			**Need a button cutter for this
			*Mount the cutter on a vertical mill and use a dividing head index while cutting the teeth.
			*Harden
			A single tooth cutter would be easier to make than a multi-tooth cutter but it might not last for all 8(?) gears needing to be cut.<br/>

			Video showing a homemade cutter being made.
			<br/>
			Spur gears could be completely encased in oil.

			Again, I want to know why we can't/shouldn't do it this way.
