Wanting to solve some speed instability I inspected my Well Tempered square motor turnable and noticed that the area around the main bearing was not leveled and uniform. There was a swollen partial ridge that was tilting the platter. Anyway, I sanded it leveled.
Tomorrow, I will repaint the sanded area, reinstall the main bearing and arm, put new 5W30 in the main bearing and STP in the arm well. The scratches around are a clear plastic Input to protect the surface fron the sanding paper.
