Alternatives to Pinion and Spur Gears

[AustinSchuh]

We have been able to join polycord pretty nicely with a bunson burner (had one lying around) heating up a big steel sprocket to melt the ends. Net cost to us, $0.00.

Also, your roller is probably spinning way too fast. Worth checking and comparing. 971's has something like a 25 to 1, or a 16 to 1 gear reduction, and I wouldn't speed that up more than 2x if at all. Check the surface speed of your roller. It probably shouldn't be much more than the speed of the robot.
