Maybe someone can help me. Back when I started using a lathe, I used a rocker style tool post. We didn't have quick change tool posts. Now I bought a used 9" X 20" bench lathe and it has a very cool KDK quick change tool post and tool holder. All new to me but I do like the conveniance. I'd like to buy some more tool holders for a boring bar and a knurling tool. I ordered some on e-bay. I beleive my size is AXA/#100 but when they arrived, the dovetail groove was about 1/16" too small. So how do I determine what size tool holder to buy?
