Part 2/8:
The narrator introduces the Chinese mini lathe, emphasizing its extensive utilization over the years. Despite its age and mechanical wear, it has proven invaluable for various projects. However, one of the main issues highlighted is the electronics inside—specifically the pulse-modulated motor— which has failed. To keep the lathe operational, they employ a makeshift solution involving a Variac transformer to control power and a secondary motor setup, wiring through the existing electronics to compensate for the electronic failures.
