Mac, the problem with 5C collet chuck for the production job, is the stock size, 2"+ square. I am not sure of the real size as I have not seen the prints yet. The last shop that did the job, messed it up to the point of about 1/3 of the run was scrap. The major tolerance bugaboo is length, + .002 / - .000. Hole is drilled than a form tool is run in to a certian depth. It is a goofy part, not too hard to make but finicky.
Another one of the no photos allowed jobs, I get once in awhile.
I could set up the job in the independent 4 jaw. It would be a little more work but it could be done.
