I have a small Delta tool maker grinder. it has a Walker Chuck on it. I have ground it flat twice. I can say it was true the last time a few years ago.
I had a parallel that needed to be ground. I noticed that when I went to pull this parallel the grind was poor on it, and it was not square, it was trapazoidal. Anyway, I just put them on my chuck together, and used some magnetic blocks to hold them upright. I had swept by hand the chuck first.
After grinding, I double checked them, and found them to be 5 thou off from end to end. The chuck no longer feels like it did when I surfaced it years ago, it's rougher, where the lead (assuming lead) lines are things don't feel as smooth as years ago. I have left things chucked up on the chuck with the mag on many times.... So do the chucks pull themselves apart, is me leaving something chucked contributing?
This is a coarse pole mag, only about 9 inches long by 5.
Thanks.
