Another
contraption I'll likely never use... at least at what it's intended for. A (smallish) boring jig with a MT-2 shank. With an old Atlas milling machine, everything is fitted or adapted to that. Add to that I seldom work with largish stuff, mostly model work where I use a reamer for the size openings I need. 5/8 inch is about the largest I generaly cut.

A nice looking kit, at a price I was willing to pay... cheap. Accuracy/TIR..... well, that's a whole 'nuther matter. What's going on here is that I ran across an interesting idea for cutting spheres. There were several videos on U-Tube, the attached link is just one. I thought I would set it up and see if it was as easy to do as it shows in the video.
My tailstocks on both lathes are MT-2 as well. Now, I have an "offset" center for cutting tapers. It's a PITA to do, but it does do. Seems there is a way with a boring head as well. I may try that and make one tool do two jobs. Looks like a real PITA to do but so's what I have now. One lathe has a homemade taper fixture. A pain to set up for one piece though, I'm not a
real machinist. So I generally use the offset center. We shall see what we shall see.
