I have this set, I like it, but I only use it for my sanding/cleaning lathe, as, IMO, I don't feel it's as accurate as the live centers that I use for cutting on my Atlas lathe. Some of the removable tips have quite a bit of play between the tip and holder, with no weight load on them.
I have made some tips out of delrin to hold a 5/16 pin, and a 3/8 for when I'm buffing/sanding, etc. a butt that has a pin installed. Works great.
