  • Telescoping Bore Gages

    Somehow in the last 10 years I managed to lose one of my bore gages and, wouldn't you know it, its always the one
    I seem to need.

    So I'm shopping around, figured that, for the price, just get a new non-buggered set.. when to my surprise I find quite
    a price range:

    New Mitutoyo set: ~$215.00
    New "Import" set: ~$15.00

    my original set is an import. Prob paid 20-30 for it. Gets a lot of use. And now I find myself wondering if some of the
    frustration with using telescopic gages (I'm not too bad with them.. but some days, I just don't have the touch) -- might
    not be with the quality I'm using.

    Any thoughts? Is $215 crazy for telescopic gages? Or are the import sets just junk and I don't know it because I've never
    used "nice" ones?

    That price is from Cromwells (UK), by the way.

    Found it funny that they're available in both inch and metric sizes.

    And yes, I'd probably just ebay a set when all is said and done.

    Well, I have an import set, which I ordered from Enco and was supposed to be PEC (Product Engineering Corp), but when received was obviously NOT.
    (Should'a sent them back, but needed them then.)

    I also have 1 (one) Starrett. The Starrett looks better, in terms of fit and finish, but I can't tell that it operates any smoother or nicer at all.

    That's the extent of my experience; know nothing about the Mitutoyu.

      I bought a used Starrett set off ebay for about $50. I think it goes from 5/16"-2 1/8". I've been happy so far with that.

        I bought one of the 'cheap' sets from Victor Machinery, and I was pleasantly surprised.
        They are 'Made in Japan', and look & feel exactly like a Mitutoyo set.
        You can buy individual gages from Victor as well, for around $10.

          I bought an economy set and after polishing the works and smoothing the ripples off the crowns they work well enough. I think they're like spindexers or HF grinders. You have to work for the diamond.

            I've got a set of Mituyoyos, a set of china imports, and an old set of Craftsman
            along with a couple of extra Lufkin and Craftsman that came as a bonus with something
            at a yard sale.
            I like the Craftsman best,(well polished and smooth from use) followed by the Mituyoyos.
            I could never get a feel with the ChiCom imports.
            If you want to trade a Metric set for an Imperial set let me know-
            All of mine are imperial!
            I cut it twice, and it's still too short!

              I had been using some older Ebay Starretts, which I like a lot. Recently I scored a like new full set of Mitutoyos at an estate auction for $22 (iI know, I suck) anyway I have to say I like the Starretts better. The Mitu's are very smooth, but I feel that the spring tension is less and it makes it harder to get a consistent reading. Maybe I just have to practice more with them.

                Yea, I noticed that too. $40.00 at a garage sale for the Mitutoyos down the tubes! My 50 yr old Craftsman are better!
                but the Mituoyos are better than still better than the imports!

                  I would like to take this opportunity to shamelessly promote my thread on how to improve the feel and performance of telescope gages.

                    The spring tension of the telescopic gauge should have no effect on how well the telescopic gauge works.

                      I had a set of "Craftsman" gages.... Turned out the "Crapsman" gages were almost 100% the reason why I was unable to get telescope gages to work for me at all. I CONSISTENTLY got readings about 5 thou UNDER size.

                      Well, I finally took a good look at them, and found that one end of some of the ones I generally wanted to use had small flats on them. Another one was almost flat, which I hadn't noticed, as I expected them to have a rather large radius which would be sufficient at their intended diameter.

                      The difference was estimated to be somewhere around the 5 thou which I was usually "off" by.

                      I looked at another one which is a size I don't use, and found that it had ridges and a "tit" in the middle on one side. The other arm was perfect. The flats etc were obviously there from the factory, since the un-worn plating was intact over the flats and 'tit".

                      So much for the "goodness" of "Craftsman" tools.

                      I had thought they were some other brand, but as I was putting them in the "sell at garage sale" pile, I noticed they were in fact Sears...... Almost certainly made by "General Hardware", the purveyor of a lot of "very nearly acceptable" tools.

                      They were replaced by some Starretts, which are no better as to "feel" , but at least have round ends on them. (yes, I did round the ends of the sears crap, but decided they were still leaving. For a low price, of course, on account of low precision).

                        Got a set of Moore and Wright's , two import sets and a PEC set

                        To be honest can't see a difference in any of them, usually use the PEC ones but started to use an import set as I lost the smaller PEC one.

                        One thing I did notice is the M&R and PEC are a 5 piece set, the imports are 6.

                        I must own the worlds best selection of internal measuring gear, because i do a *lot* of bearing re sleeving I have splashed out on internal mics, bore gauges, internal mics, you name it, I've bought it but still drop back to telescopic gauge and vernier to get close and micrometer to finish off.

                          Do you have any of these.

                          I have an imperial set..Swiss...made by AG Technica...and would like to have a metric set aswell, but I have never seen any auction wise....very nice to use and the inbuilt vernier gives a direct reading.

                            Over the years I've had two or three sets of import gauges and have always struggled with them a bit--usually had to take several tries to be sure I was getting consistent readings. I recently picked up a 6 piece Mitutoyo set at a local clearance shop--for only twenty-five bucks, I might add--and I really do notice a difference. The Mits have a nicer, smoother feel than anything else I've used and I'm much more confident when using them. I've practiced on some bores of known dimensions and I now find that I'm almost always bang on with the first reading...

                              Another trick I found with the import gages is to exercise them to wear down some of the 'crunchy' bits.

                              set the thumbwheel so theres a light amount of drag but they still pop out, and just push the plungers in the full way with your fingers and release 100 times or so.
                              Once they have worn in a little, they are much smoother to use.
