I think you're going to run into a problem using your relatively small
teletype motor to spin-up such a heavy 3/8" thick disk.  I was barely
able to get such a motor to spin a 09" thick x 6.12" diameter G10 disk
with just 4 brass acorn nuts electrodes, and it utterly failed to sync
with anything larger.  I'd strongly recommend using a propeller gap if
using a Teletype motor.  My SRSG page:
