+The motor on the lathe has been fixed. The centrifugal switch was failing to turn off the starter winding, as it was slipping on the shaft. We pushed it firmly back into position, applied lock-tite and punched some holes in the shaft to stop it moving.
+The adapter plate has been machined to fix the 4-jaw chuck. We also confirmed the critical face alignment stays true when it is put on and off the machine, using a DTI. We took a small amount off the outside diameter of the plate for cosmetic purposes, in order that users would not think the plate was rotating asymmetrically.
+The circuit of the machine is extremely simple. It consists of a few switches (some are e-stop, one of which reverses polarity on the starter circuit), a contactor plate which is always engaged when the machine is moving, and not much else.
+TODO:
+ * Replacement oil will be arriving tomorrow, not sure when it will be changed.
+ * A temperature sensor + buzzer combo will be placed on the motor to alert users when it is getting hot.
+ * We will measure the power draw from the wall.
