Modify of Synchronized gear unit for router lathe

Mar. 16/2019
Last month I took out the router race after a long time and made a screw. But it took a long time to center. I changed the coupling to a ball joint.

2.Move the screw shaft 10 mm portion a little cut and connect the ball joint.
3.It began to rotate gently.
