I have a shallow hole, apparently bored with a 7mm end mill, that is .056" on the edge of it and .052" in the center. It is in a polished stainless steel article so the plug must be fitted and polished on one side prior to insertion. Any ideas? Joe |

Perhaps I should phrase the question another way. I need a .275" (7mm) disk, .056 thick, with a thinned center on the bottom and a polished surface on the top side. How do I hold such a work piece? The work must be done without access to the article that it is intended for. The article is a thousand miles from my shop. Joe |

The way I would do it is machine the O.D. in the lathe, then do the thin center while in the lathe while leaving a stem at the center of the thinned part, then part off to the thickness plus a little extra for finishing and polishing. The stem is for holding either in a hole or by hand until you get the required finish on the polished side. Cut off the stem with a dremmel or similar tool and clean off burr as needed. You could put the stem in the lathe chuck and finish that way also on the polished side. Take light cuts on a thin part is always a good idea. I hope I was clear. I have chucked thin washers like that and machined out center hole with good results many times. If you feel lucky you could face off the finished side in the lathe using a real thin spacer taped to the outside of the jaws and have it stick out enough so the cutter will not hit the jaws and take light cuts.

Thanks for your reply Paul. Using some of your suggestions and some of my tooling I was able to do the job. I need to repeat the task and will get pictures and and post it under the "How To" forum when I do. Joe |

Joe, Which way did you do it, just wondering. Will look forward to the how to post. Paul |
