    I was given the task (opportunity) of learning to run a machine shop that is like a time capsule of 1960s and earlier machines. I was gifted a box of old lay out tools and these buttons were included. I never knew what these things were or how to use them. I cant wait to try them out. If not for the knowledge of people such as yourself, i would be lost. Everything i know about manual machining has been taught to me by old timers that are perfectionist. Its very overwhelming but rewarding

    Hi Dave. Interesting toolmaker button history demo. From an era machine tools couldn't be counted on to to provide precision positioning. This button technique was obsolete decades before I started my apprenticeship in 1964. The only set I've ever seen in real life was owned by an old toolmaker I worked with. His tools were date stamped 1930s! (Rip Art). Let's hope any newbies watching don't think buttons have a place in today's shop. 😊 All the best from Iowa, Mike

      Thanks for watching and this comment. Depending where you live in the World, you may have a difficulty in trying to find a set as it is " Old Technology " but do not despare. You can make some out of ground rod such as Silver Steel or Drill Rod. As long as you ensure that the bottom face is machined and honed perpendicular to the OD then all will be well. There are some rollers used in roller bearings that are hollow in the center, if you know anyone who works with replacing bearings and can find you some. In a set there are usually 2 short ones and 2 long ones. Any size bolt threads that you want, just as long as the hole in the rollers are a very sloppy fit, about 60 to 80 thou oversize to allow for the button to be accurately adjusted. Regards.

      Hello Howard, thanks for watching. Yes the 'Youth of Today' don't realise how easy their engineering life is today, compared to the mid 1900's onwards. DRO's were just coming in about 1960, but not like they are today. Big display units using Nixi Tubes ( glass tubes with numbered wires inside and a neon gas that glowed when each number was connected) Needed 1 Nixi for each digit, so if you wanted a 1,000 mm scale you needed 6 tubes if you wanted to read to .05 mm.

We often made our own buttons from silver steel rod by drilling the centre bore hole and facing either end whilst in the annealed state. After hardening they were ground to the finished diameter and the ends lapped....all good fun.

    Buttons permit accurate manual layout on large items too big for one's milling machine. A piece of suitable steel fitted with drill guide bushings is a handy way to make holes square to the material. DRO are lovely for backlash compensation which is probably the best reason to buy one.

    Fantastic video Dave !
    You are spot on with the comment dying art - the lure of the DRO is strong ! Problem with the DRO is it doesn’t account for wear in the machine or if the scales are as accurate as they state they are . If you can find me a home shop machine that you can zero the DRO then lock the ways without the DRO changing I would like to see it !
    For home use a set can be made that will serve the job at hand - sure no where as accurate as a proper set but better than nothing .
    It is fantastic that you are showing how to use these tools and procedures because
    a lot of hobby machinists go through their whole life not really knowing or understanding why the hole they just drilled isn’t located where they wanted it , it maybe close but when you are making a Steam engine cylinder with a bolt on head and steam chest that may use many studs to hold them in place a couple of thou variation on the stud location on a few different studs means that cover isn’t going on without some fettling or severely oversize holes .Yes they can clamp both together and drill and tap the holes in one go but any error is the applied to the mating part so it will only fit on in one orientation .

      One tedious factor is that you have to first mark out the holes positions and drill and tap them to get the screws and buttons near enough before mounting the button.....BTDT.....even if the part is hanging in the air and not on a table you still have to have the button near enough before you can dial up on it.
      On the aspect of slides moving when tightening the lock screw........utter crap, if the DRO shows that the table moves you slacken the lock and move the slide back etc......DRO's are far more accurate than practically any person can successfully apply buttons and they ignore screw backlash........ glass scales are accurate to 5 microns (and you need to have a set of gauge blocks to use buttons too)......but I get what you are driving at.
      Once you have a DRO and use it you never go back.....EVER......it makes calibrated dials on machines obsolete and can go from Imperial to Metric if required.....can't imagine why anyone would use Imperial now.
      BTW....I thought the UK went Metric in 1972 (when I was last there).....why are you still using Imperial measurements?..........only the Yanks like Imperial.

      @@gangleweed
      RE the scales moving , the scales are not mounted on the feed screw centreline but on the edge of the table or Y axis slide . They are parallel to the feed screw movement for certain but when you clamp the slide any clearance is taken up and this clearance which all machines must have regardless of how small can cause the numbers on a DRO to move .If this movement is not exactly perpendicular to the scale it is magnified by the distance the scale is from the axis centreline , I’m not talking about tool room quality machines that we all would love to have - many have old and worn machines and even the new Asian made stuff can have problems here . So you set it up , zero everything then clamp it up then notice one axis is now reading different - do you re adjust it or leave it ? Did it really move in the direction as stated by the dro or was it a small amount of table twist ?
      RE scale accuracy - yes they can read very accurately but did you confirm this and compensate in the settings as per the installation instructions ? Not all scales are created equal and the machine may not be running top end equipment.
      I use imperial here because choose to and I know that Dave would have spent his time using it , I can use either imperial or metric and I’m not located in the UK .
      These days most of this is not relevant except in a home workshop as the world has gone CNC mad and many of the traditional skills are being lost - at least Dave is trying to keep them alive for those who wish to learn them !

      @@ianbertenshaw4350 Well actually the glass scales are on the sides of the table and saddle and any table movement should first be taken up by the gibs......if the table ways are so worn that they wobble then it's a lost cause and glass scales won't do any good.
      You have to know your machinery to know where to fix it or adjust it or at worst take it apart and rework the slideways.....if you lack the skill to work on a machine the only solution is to dig deep one time only, take out a mortgage for a couple of grand and buy a forever machine that will be reliable.
      I'm a time served fitter and turned and reworking worn machinery has been my life so lucky me.
      Incidently, on the cost of machinery, my lathe is a 1930 Colchester Bantam, bought in UK for 70 pounds Sterling and shipped with my belongings to OZ in 1981.....I had to recut all the slideways on the bed with a hand planer before scraping.....long story.

Amongst the things that he had no clue were a set of toolmaker buttons. He was impressed with my trammel set, he had never seen someone layout a bolt hole pattern, center punch, drill the holes, and everything came within tolerance... he would have flipped if I would have drilled the holes with my hand powered copy of a Cole drill

      @daveticehurst4191  Год назад

      Hello Edson, thanks for watching and your question. YES, mark out as accurately as you can ALL your intended hole positions, drill and tap a hole for the button screw. The hole in the button is quite a bit bigger than the screw, thus allowing it to be moved around to set the distance accurately, then lock the screw down. Obviously if you need more than 4 accurate holes, you would need several setups. Drill and tap all the holes, pick your first 4 holes, then machine 3 of them. If any other holes are still referenced to to the last button, do not machine it, but remove the plate and set up the next 3 buttons with reference to the remaining button that was set from the first alignment. The number of accurately positioned holes by this method is unlimited. Hope this clarifies the question. Regards.

    Sir, have you done one on what I was taught to call tooling balls? I do not know what they call them over there. Spheres of a known tolerance for radius used for measuring purposes. I always like that we call things different names but they are the exact same thing.

    Am I missing something here Dave? How is this any more accurate than transfer punching? BTW, in Canada, in the 70s transfer punching was taught in grade school industrial arts .

      Thanks for the view and your comment. Providing that you have accurately set them up, and dialled it in, this is accurate to Tenths of a thou. To use a transfer punch which I consider is highly inaccurate, you would need a part to punch through. This method is used to make the holes without any other mating part. See this video for the way to transfer holes WITHOUT using transfer punches. Thanks.

      Has nothing to do with transfer punches - Toolmakers Buttons are a precision tool - Transfer punches are butchers tools compared to them . Transfer punches are ok if you only want a hole somewhere close to where it needs to be , if you want a hole to be located within a ten thousandths then buttons and indicating is what you need . Set up the button ,set up the job in the mill or even better jig borer , indicate , bore the hole undersize with a slot drill , finish bore to size with a boring bar .

      @@daveticehurst4191 Yes, Dave, that video, and your comment about it being an American thing is why I mentioned about it having been taught in Canada... Now since neither you, nor @ian bertenshaw, answered the question of how, just gave the standard British rhetoric of our system is best... HOW is it more precise? Is it about the holes through the buttons being larger than the screw holding it, and therefor being able to take exact location from the gauge blocks?
      BTW, I do understand that a "standard" set of transfer punches is no more accurate than a big-box-store set of sale priced HSS twist drills, but, every proper machinist I know, who works in a jobber shop, has a few precision transfer punches that they have had to custom make for a job at one time...

      @@trollforge Hello again, thanks for your reply and question. YES, it is because the screw is smaller than the hole in the button that allows it all to work and be the most accurate. Mark and drill as accurate as possible, should be able to get the holes positioned to within 0.015" 1/64", then tap for the screw. As the demonstration showed there was plenty of wiggle room for the button to move in any direction around the screw. Hope you have now grasped the principles behind how they work. Don't know when they were invented, probably over 100 Years ago now. I do know that the Jo Blocks were specially invented for the Ford Factories in the early 1896. Thanks for your interest in the matter. Regards.

      Hi Ryan, Yes it was the only accurate way before about 1970 when the very first DRO's came out. Early DRO were very bulky and did not have the functions that modern day ones have. The Phips one of about 1970 used what were called NIXI tubes for the numbers. It was a vacuum tune filled with neon, about the size of a small radio valve. Inside were wire numbers 0 to 9, they lit up orange when the voltage was applied to whichever number was selected by the electronics box. You could only do 1 measurement, there was no INC or ABS switch, only whatever you had decided it was going to be. Thanks for watching. If you do not have a DRO on your milling machine. it is still the only way to get absolute hole positioning accuracy. Regards.
