      Algorithms are marvellous things sometimes. So long as everyone bears in mind that "I Have No Idea What I Am Doing But I Am Not Afraid Of Failure" is my hidden mantra, there should be loads of fun to be had. if I ever work out how to use this editing software and keep oil off the camera lenses, things might get better. Apart form my terrible TIG welding, that's never going to improve, I'm just rubbish at it.

    I designed a tailstock DRO holder for calipers and then discovered that it interfered with the toolpost in use, so started looking for alternative designs. I really wanted one that doesn't permanently occupy the top of the tailstock (that's where the oilcan goes during tapping and parting...) and the idea of a tab and magnets is great. Starting over now on my design! ☺

    • @MachiningandMicrowaves

      This can be a little tight when using a rotating centre in the tailstock with small diameter workpieces, but it's nice to be able to pull the scale off when needed. Two pinch bolts hold the collar to the tailstock quill so that's an easy thing to remove. Hugely useful accessory

  • @FullSendPrecision

    I've got 3 vernier calipers. A moore and wright. A fractional moore and wright and a mitutoyo. Not only don't they read the same, the difference is not linear. At different diameters the caliper reading the highest could change with no logical pattern to it.

    I'm going to have a go at this, thanks. My Hardinge tailstock is rather curvy though and needs to be fully retracted to eject stuff. So my plan is to cast a carbon fibre cover and bond the scale to that. Then use the handwheel end to mount the other end of the scale. We will see....

      It's pretty much identical to the cheap calipers, although weirdly, it isn't identical in the way it mounts. They fill with oil every year or two and need to be scrapped, but at £25 or $30, that's not too bad

      It's firmly in the "it'll do" class of metrology, but it's repeatable even if it lacks absolute precision. My subtraction issue is so bad that it would lead to scrapped parts. My mother has the same brain-wiring issue, and she used to work in finance back in the days when "computers" were humans. She did have mechanical calculating machines though. She expressed some concern about my under-age drinking exploits when I played her the intro last night!

    For those more apathetic, extend the quill a bit and stick your mag-base indicator stand to it. Then put your dial indicator against the face of the tail stock or another magnetic block on top if you don't have the space. But it's prone to getting bumped and gets in the way, so one should really get around to making one of these someday.😉

    • @MachiningandMicrowaves
      @MachiningandMicrowaves  2 роки тому +1

      I do like a nice dial indicator. One option I'm considering is hacking the remote display protocol of these cheap scales and adding a webserver and wifi interface using a Raspberry Pi or something. Then I can have a large analogue-style indicator display on the wall display in the shop. That might be a neat facility, especially if I mix in a microscope camera feed looking at the tiny parts I'm making.

The big vacuum chuck for turning thin plastic and dielectric parts should be the next, but I have an operational microwave vid that I must get published before the Radio Society of Great Britain magazine hits the streets, and several small antenna parts to get made and shipped first.

    • @MachiningandMicrowaves
      @MachiningandMicrowaves  2 роки тому +2

      It will feature in an upcoming vid where I need to modify my lathe headstock spider to add a fourth M8 screw with a brass tip. The lantern chuck is used to hold the M8 capscrew firmly in place and prevent rotation as well as keeping it coaxial with the lathe so I can turn it to length, then drill the end, fit the brass insert and finish it. Without the chuck, I'd have to try grabbing the head of the screw in a chuck, or perhaps put the lathe in reverse and use a rear toolpost and fix the M8 screw in a tapped hole in some scrap or something. They are using mainly by clock and watch makers to make really tiny screws.

      Tony is just next-level, isn't he! The effort he puts into lighting and editing is immense. I'm full of ideas but lacking skills and time, but I take influences from Derek at Vice Grip Garage, Quinn Dunki and lots of others. I'm not aiming to be educational and passing on decades of machining skill, because I'm a beginner at this stuff, so I watch Robin Renzetti, Joe Pie, Tom Lipton, Brian Block, Kurtis, Chris Maj, Clickspring and others to try to learn stuff. My focus is around using machining as an enabling technology for microwave/mmwave weak-signal experimentation, with a bit of tool and fixture making and some practical experiments

    • @MachiningandMicrowaves

      These ones work remarkably well and the batteries last longer than most. They are pretty much a consumable item though. I've replaced the battery twice in three years and the scale died because I kept dripping oil on it. I have two dial calipers and two vernier calipers for when I can't find a battery!

      I saw that when I was editing and went back to check. Definitely marked as the right size. I don't have any imperial tee-bar keys. I am going to measure it when I get back into the shop today, I am wondering if the tolerance on the batch of screws is poor. I'll check the fit with my "good" sets of keys. Those keys are the ones I keep near the lathe and are 5 years old but don't get much use. I'll have a look under the microscope. Well spotted!

    Nice little project presented in an entertaining way. I have though one thing that puzzled my dusty grey cells, it appears that your scale has units in mm, inches and F. What is F, Frequency, Farads, Force or some other obscure archaic unit.

    • @MachiningandMicrowaves
      @MachiningandMicrowaves  2 роки тому

      Fractional inches. Some of them do 1/128ths, this one does 1/64ths, but doesn't have any sense about showing 16/64ths as a quarter inch. It's not something I ever use as I think in decimal inches and convert the fractions in my head. I *can* do mental arithmetic division, but I have an Alexa thing in the shop, so I can simply yell "ALEXA, CONVERT FIFTEEN SIXTY-FOURTHS OF AN INCH TO MILLIMETRES" and she says "0.2344 inches is 5.953 mm"

    Of by one errors? I worked with a guy who enjoyed? writing his code using datastructures he designed that were either 0 based or 1 based indexes and calculations used to index into these datastructures were freely mixed together. Needless to say it was the worst code in the system and just before I left that team the general wisdom was to not make any changes in there at all. Me being the last person that had made a change to that godawful mess I got to be called the "expert" while the original author (my manager) would make every excuse not to look at or opine on any change. Leaving was just too easy when the time came.

      Nope, that triples the price. At least. Three years for £22 seems reasonable enough. Perhaps if I didn't drop oil on it, it might last longer. A Mitutoyo or SPI IP67 sealed version would probably end up getting wrecked by having something dropped on it. if I was really serious about it, I'd be using an inductive/LVDT scale with steel balls in a preloaded tube like Newall Spherosyns instead of this cheapo capacitative slider.
