Odie, the pivot points are set to 30 degrees and 90 degrees. I would guess you could add others if you wanted or needed to. After doing some turning on it, I don't think I would add any. The 30 degree setting is very comfortable for bowl turning, and the only way I would use the 90 degree setting was if I wanted to round out a table top. It is awkward for regular bowl turning because of the outboard turning set up. It doesn't slide on the floor like the banjo on the lathe does. I have turned a few platters in the 14 inch range and have no problem getting the bowl rest around it.
I am also a fan of the Robust Banjo and the sliding wedges that secure the tool rest in place, and I like it much better than the standard set pin. Only way I found the standard type to hold the way I want them was to have 2 pins. I can't remember exactly what PM did when they came out with the C model, but they used the wedge system also. The problem I had with the Robust one was that the wedges would pivot and I some times had to stick my finger in to get them back to vertical so the post would fit in.
I have never been a fan of the pot metal handles on the set pins. They are far softer than the metal used for the set pin, or at least the pin head. That is a guaranteed fail as the splines wear out on the softer handle. My AB now has a mini set of vice grips on them instead of the handle that came with the lathe. After I wore out my second one on my PM3520A, I had a custom one made. Don't know why the more standard handle that you find on your bench vises, a T where the top part of the T is what you tighten up and loosen up with, and that handle slides from one side to the other. Much more convenient, efficient, and easier to keep out of the way. Ran into that problem with my Liberty. I think Oneway has a handle that is on a hinge pin, which is kind of the same way... Maybe some day I will build my own lathe...... Probably not, just too many other projects to keep me busy, but who knows when the inventor syndrome will kick in again....
