How to use a sticky pin.

[jjr2001]

How timely.. I had this tool in Dad's tool box and thought he called it a Wiggler and I knew it had something to do with finding center.
I had always used the common edge finders that you find today with the cylinder on the working end. Now I have a tool designed to find a line!
A few days ago while working on my clamps I actually used it to indicate an edge. Not sure if that was proper use but it worked.
First find one edge by getting the needle centered with the fingers. I had the depth just deep enough to have the taper on the point touch the edge of the part. Touch the edge of the part by moving the mill table and zero the DTI. Moved it to the other edge without changing the height and found that edge. Divided by 2 and found the center. Worked great.

Thanks for the demo Homeengineer.

Now if I only knew how to use the stems with the ball on both ends.

Here is a picture.
Note the sleeve on the housing. The housing is cracked and it was repaired with the sleeve.
