Part 1: https://www.youtube.com/watch?v=HiZ7l2i_l_4
This is part 2 of my boring head build in which I finish this toolmaking project.
In this second episode I make the adjustment screw with fine thread and dial and the bearing parts which hold the screw in place. After this I finish the main body parts including some milling into final shape and drilling all the boring bar holes. In the end I electro etch the markings to the boring head body and the scale and numbers to the adjustment screw.
I hope you find this build interesting. Feel free to comment and ask your questions and suggestions below in the comment section.
