  • Pet gripe with rulers

    I work mainly in metric and like a rule that has imperial on one side and metric on the other.

    The imperial side tends to have fractions on the top 64's. 32's, 16's and 1/8's with decimal on the bottom 50's, 20's and 10's

    The metric side is usually the same top and bottom 1/2 mills to 50mm then 1mm to the end.

    Occasionally you might get one that has 1/2mills at the top and full mills at the bottom but it all depends on the lay of the work which scale you use.

    Now the gripe, why do they insist on marking in 1/2mills ? it just clutters the rule up and you are more liable to make a mistake on the wrong division that guessing the halfway point. 1/2 a mill is only 20 thou and cramming these in causes a lot of confusion.

    When you are on the full mill divisions you can even guess off to a 1/4 of a mill or 10 thou but it next to impossible to split the 1/2 mills without going bozeyed.

    Incidentally I must have about 10 rules that are all different in their layout of what goes where but I have never seen ones that has full mills top and bottom.

    White rulers

    John.

    Try using a carpenter/builders 1 metre 4 x (250mm) white folding rule.

    They are calibrated in single mm on one side and to 1", 1/8" and 1/16" etc. on the reverse. They are a pretty good quick mm>" conversion aid as well.

    Being heavy black marks, figures etc. on a white back-ground it is about as good a contrast as visibility factor as you will get. I've snapped a couple of mine at fold/hinge but the short 250mm/10" end sections come in pretty handy. I've cut up small sections - say 2", 3", 4" etc. to get into those bloody awkward hard to access dark spots etc. They work well on the welding as well.

    I use than as my default ruler now as I can easily halve and quarter a mm (40 thou) - and better. I only use a standard machinist's steel rule when needed - ie rarely - as my old plastic dial indicating (non-digital) mm 150mm long (yellow) does most other stuff unless the "better" stuff is needed.

    I can see that white rule quite clearly in some quite dark spots that would require a light etc.

    Give it a try - you might be surprised.

      So what you're saying is that you've had your fill of despotic rulers

        I carry a 6" rule in my shirt pocket, it has mm's on one side and end english on the other side, in decimals, the main marks are spaced .100" and I think it has smaller marks every .025". Mitutoyu if I remember right.


        This really adds nothing, I just felt like typing.

          So, I am not the only one to wish for one more combination of rule graduations.

          Hi John, my thoughts exactly on the .010 graduations, .050 is much more useful. I even went so far as to get a quote from Starrett to make a rule with custom graduations, as you might expect it was astronomical for one rule, about $300 for a 6" rule. If there was any agreement on what graduations would be useful we could probably do it for considerably less??

            I like the white rules with black markings. What I'd really like is one with the same markings on both edges, lining up as well. The full division marks can go right across from one edge to the other, like every inch or every 5 cm or so. Grab the imperial one, or grab the metric one. Screw off with the 'across the ruler' interpretations.

            Make the metric ones more expensive, so we can save the tried and true imperial system.

              Don't get me started. I've got a gripe of my own where tape measurers are concerned. Is there some freaking reason they all have to read from left to right when most people are right handed and would like to mark with their right hand? There was a very brief time when someone came out with a right to left reading tape but not any more. Now you have to fumble with the bulk of the tape in your right hand and then switch grips to hold the pencil in your right hand to make an accurate mark. Just smokes my arse, absurd, can't get it out of my head. I was okay until you brought this crap up Stevenson

              It is true, there is nothing free about freedom, don't be so quick to give it away.

                  I guess that saying about teaching an "Old Dog" new tricks is true. :-)
                  Can't you read the numbers up side down? :-)

                    Y.O.D.
                    LOL, I can relate to that, Give me a tape measure with the same markings for each side of the tape, I don't want to try and read the dammed things upside down. I also have the R-L and L-R reading tape measures from Lee valley but I see no reason why some tape measure manufacturer hasn't at least tried to use the product they make and put the markings so that a tape can be easily read when measuring in either direction. Just one more PITA in the world that no one wants to actuly fix.

                      It would be nice too if rules were marked L-R one side and R-L the other.

                        My rules have the metric on one side and inch on the other both having the same reference/zero on the same and of the rule. If I want to do a conversion I just dig my thumb nail in on the edge of the rule at the point I want to convert from and roll the rule over to the system I want to convert to and there it is right under my thumb nail - dead easy, quick and accurate.

                        1mm ~ 0.040" so halving and quartering to 0.010" is pretty easy.

                        1/16" = 0.0625" ~ 0.060" which is easily halved to 0.030" or quartered to 0.015" and a "bit under" is near enough to 0.010" and a "bit over" is near enough to 0.020". Measuring/setting to "thirds" (0.020") is easy with practice as well.

                        Splitting an etched/impressed black line on a white background is easy as well - and that is getting into "a thou or so" territory.

                        It never ceases to amaze me just how actuate and versatile the Mark 1 eye-ball (as supplied) is. I make sure I use it.

                          Despots

                          Very droll Cameron - I liked it.

                          If despot = stand-over man and if or as HSM-ers stand over their machines (and each other on occasion) then it seems that:

                          HSM-er = stand-over man = despot if, and only if, they make it a rule to measure up.

                          Further, if having your fill (or getting filled up) with or by said despot are you not getting 6" (minima) or 12" (maxima) inserted by said despot as he stands over you - as a rule? which meets your criteria:
                          So what you're saying is that you've had your fill of despotic rulers
                          But if said despot/ruler tosses you aside is he not a "tosser"? which according to Wikipedia here:
                          http://en.wikipedia.org/wiki/Tosser

                          says that said ruler which = ruler + tosser = wanker:

                          http://en.wikipedia.org/wiki/Wanker

                          There's lots of real or potential rulers here.

                            I was born left handed. My Grandfather lived with us when I was very young. He thought being left handed was a sign of retardation. He made me use my right hand for everything. When I was around him I had to put my left hand in my pocket. If I used my left hand to do something that I could have done with my right hand I got a whipping. He was a real prick. BUT now I am ambidextrous. He made me write right handed so I use what ever hand is the most practical to write with!!!

                              Well, left to right is OK if you are measuring as opposed to marking. They do call them "measuring" tapes. Perhaps you should buy a "marking" tape.

                              Or stand on the other side.
