    Strangely, you seemed willing earlier to agree the Albion temperature compensation was a joke.
    Huh? You must have misinterpreted what I wrote.

    it does nothing more than add or subtract the effect of any temperature differential between the part and the gage.
    Not according to their description. It also relies on an accurate characterization of the temperature response profile of the instrument and compensates the instrument itself, independently of what is being measured. I'm not playing word games.

    It does not compensate any more than someone with a couple of temperature probes and a $2.00 calculator is capable of doing.
    That would be called "manual temperature compensation". It requires a good profile of the instrument response at different temperatures. The only real difference between manual compensation and the Albion products is automation.

        If he is a she how do you manage to get the last word in ?

          We don't.

            I think its about time the "point-scoring" stopped and the level of discussion got back to what Rick Barber originally intended.
            Tiffie,

            As you are fairly new to the forum you probably don't realize that Jim and I have a go at it every once in a while. There is no blood involved and you will note that no personal attacks are involved. It's more a hobby. I have a lot of respect for Jim and on the too infrequent occasions when he posts photos of some of his work it is obvious he is an excellent machinist and craftsman. We are both stubborn though.

              It is all part of the fun. Through debate and the expression of different opinions and viewpoints, often a new perspective can be obtained.

                From speaking with several of the regulars here offline and in real life, a lot of folks find these monthly Evan-centric flame wars annoying, and they certainly detract from the original poster's intentions, since most people just tune-out of the thread.

                More importantly, just like on the 3-phase power thread, you're not convincing Evan of anything. He believes he saw a temperature compensated Master vernier, and there's nothing you can say that will convince him otherwise.

                  What took you so long Lazlo? Been sleeping?

                  Where do you get the idea that any flaming was going on? If I wanted to flame there wouldn't be any doubt as to my intention but that's a waste of time and serves no purpose. You on the other hand don't seem to have anything better to do. You are, quite simply a troll and just can't stand to see this thread come to a peaceful conclusion.

                    I like the idea of starting a new thread although my motivation is rather selfish. The metrics on my web site show very few people visiting this article and I believe its debut was swept aside by all of the other discussion.

                    I did find the discussion about temperature compensation interesting and read all of it. Little of it can be applied to the article because I am convinced the HF caliper has no TC.

                    The excellent work, still in progress, by ckelloug (Cameron), will enrich the next version of this article as well as another one on the Shumatech DRO.

                    I hope to see you all on the new thread.

                      Evan,

                      I've contributed technical data to every thread that Rick has posted in the last month, including this one. But as soon as it turned into a "yes, there's a temperature compensated caliper" "No, there's not." thread, I tuned out, and a lot of others have as well, as Rick noted.

                      OldTiffie is saying the same thing in the post immediately above mine -- is he a Troll too? ...and Sir John is trying politely to either stop the circular argument you're having, or at least redirect it back to Rick's original topic.

                      Cheers,

                      Robert

                      • Rick, I appreciate the effort.

                        Apparently, so do the practical people on this board.
                        It is a reminder to those of us who have crossed the analogue/digital boundary.

                        Keep up the good work.

                        Best regards,
                        Lin.

                          OMG, now a Metric heat sensitive caliper?

                          Oh the humanity, When will it end.

                          • Evan your telescope appears to be a fine piece of work. I wonder tho how you deal with stray light with the open construction.
                            Also it is not thermally compensated. I conferred with a friend who is an engineer at the University of Arizona Optics Labs and designs telescopes for places like Kitt Peak( you may have heard of them). The design of an instrument to be unaffected by temperature is called passive athermalization.

                              Did that work for the HST?

                                Would you mind awfully providing me with personal details like date of birth, next of kin etc so I can take out a personal insurance policy on you whist you are prodding Evan with a sharp stick.

                                I can see a pending claim coming which could net me a few $$$.
