Alright guys. Got my welder and I'm about to mount the motor, but I've run into a problem finding the sprockets I need. I decided to go with a 6.5:1 ratio, meaning a 14 tooth sprocket on the motor and a 72 tooth sprocket on the wheel. However, I'm having trouble finding a vendor who sells 72 tooth sprockets.
Do anyone have any vendors in mind for 72 tooth (or maybe 128 tooth?) sprockets? I should mention that I have found some sites that sell 72 tooth, but they're like $80 a pop.
On to my second issue, the controller. Can you guys do me a favor and keep your eyes/ears out for a used controller? Maybe one from another project that has been abandoned? I'm looking for a reasonably priced controller that's below the $300 mark.
