Help needed to find how the thread works in a boring head. I have made a head and it works fine but I only have a 3mm thread (0.5mm) per turn or
0.005/division) as the source of movement. Seeing is believing as they say and if I can view how it is done then I should be able to repeat it. I know that the threads are ground not turned and this is why I went for such a small thread to alliminate as much back lash as possible. Any help in finding this info would be much appreciated. The usual search has not found any diagrams or schematics.- posted
