Once the disc and waste block glue up are dry it’s time to mount on the lathe.
Remember to check the rotation and clearance by hand before powering up the lathe. If your lathe has adjustable speed, set the speed to its lowest setting.
Balancing the stock is nothing more than scraping the edge of the disc until it is concentric.
Truing the stock is nothing more than some light facing cuts on the front face of the stock.
All ready for the next step.
