It's simply a piece of Plasticine with a needle embedded in it that you stick on the end of a cutter, run it at a couple of hundred revs then true the point up with the edge of a 6" ruler.
Once the point is running true you apply it almost down to the marked off position not touching it etc.
I used it for almost 40 years, still have and use it,...…. I bought a wiggler set too, but the sticky pin allows you to attach it to a tool already in the chuck whereas the wiggler needs to be in a drill chuck etc.
