Tool Does Anyone Still Use a Wiggler?

Hi All,

I do.

Here is a photo of one which I use to centre a punch mark in the end of long piece of rectangular stock held in the 4 jaw chuck. It takes a bit of setup but with a little practice I can set the punch mark on centre to better than 0.001". It was one of the first tools I ever bought when I purchased the lathe 50 years ago. It was made by Starrett and I don't know if this tool is still made by them. Like everything Starrett, it was not cheap but beautifully made and when needed it is the only way I know of doing something like this. One can increase or decrease the sensitivity of the wiggler by moving the gimble point closer or further away from the punch mark.

I still use a wiggler on the cnc mill some times. It's a simple device that works well.

I still use one too. For various things.

I have a varient of that principle that I want to use for chambering. That work is done in 10ths. But I have not been able to get it to work as well as a long needle dial test indicator. It isn't repeatable. I have not been able to figure out why not. Some day, I'd like to setup to use it when a group of machinists are here with me to help demystify it.
