X Axis

Turns out Home Depot has 3' lengths of 5/16" rod. I picked up 3 to make up for the metric/imperial problem with the ones from McMaster (1 metre > 3 feet). Should be good enough for use in the XY frame.

Assembled the carriage and X motor bracket. Did the drill-and-self-tap thing with the grub screws again. The rods were difficult to push into the motor bracket. Required a "tap gently with hammer while cringing" approach. Used a store-bought pulley on the motor.
