  • Ok, go ahead and have a laugh at my expense.

    I was turning a part today, basically a ring, 1.4" OD and 1.320" ID. X .5" long.

    So after turning the OD I started boring the ID BUT I accidentally used the OD diameter instead of the ID dim. So anyone want to guess how long it took me to realize that the OD and ID can't be the same Diameter.
    The shortest distance between two points is a circle of infinite diameter.

      that's when you hand the foreman a bag of chips and say "here's your part"

          That's truly losing a part in the chip pan.

          I've turned a 3 and a half thou walled part before that I thought was gonna end up like that.

            So, how many rings did you turn before you discovered your mistake ?

              Well done Lugnut. My claim to fame was to add an O-ring with 1.25 ID on a flashlight body that was 1.35 ID. I did the math. 1.35 is bigger so I should have had plenty of room My math said that I should have had .05 clearance on each side!
              At the end of the project, there is a profound difference between spare parts and extra parts.

                Everything is transparent if you make it thin enough.

                Thanks for the laugh. Everyone needs a good laugh now and then.

                    He did. There just wasn't much to see.

                      I learned a long time ago that brain farts is part of living with any craft. You just had one....

                          I shouldn't say this but it took me three times to get a dovetail right once. I just couldn't seem to get my head wrapped around the "slot" getting bigger when I was so used to parts getting smaller on the lathe. I was sneaking up on the last .020" with wide eyes and notes posted everywhere on that last try.

                            You've merely shifted from a Boring Operation, to a Facing Operation.

                              Everyone will at some point pick up a wrong number off the print. In your case it's actually great because there is no evidence of the F-Up left. So it did not happen.

                              Thanks for sharing.

                              Best Regards,
                              Bob
