Ball and Concave turning attachment

 This is the second edition of the Ball and Concave turning attachments that I have been making for the Optimum D180 or OptiTurn TU2004V mini lathe. Except from the better finish I have made some small changes also to improve the functionality and increase the ball diameter and the concave radius. I have use this attachment to cut balls in plastic, aluminum, bronze and mild steel without any problem.

Update: I added a few photos of a third edition that I made for a customer that takes small 5x10mm HSS bits. Ideal for turning wood.
