    Only thing is those machines do not check carbon content, and they emit X-rays and I believe have a limited life.
    Gold, the colour of choice for the discerning person.

    Yes Kryn, that one cost one of our major scrap recyclers around $40K, as compared to the previous one they used to use which cost 4 or 5 times more and was limited in what it could do.

    A better scan showing an exact match, it was a bit hard holding the gun steady on the tapered circular arbor while it took reading.

    I finished the last bit of grinding today, touching up the mating faces and grinding the internal locating diameters to 60mm.

    This is the set up I used to drill the 10mm pin holes using a Tungsten Carbide end mill to achieve the final diameter. The holes are 40mm between centres.

    Crisp as usual Techo.

    How did you grind the recessed face of the arbor? A stone with a recessed centre on an internal spindle?

    Yes Bob, that's exactly how I did it.

    Now you have me curious Techo as to how the arbor is mounted to the workhead. Is the brown spacer hollow and both the arbor and spacer held in position by a drawbar? (The problem with such a scenario is that you probably ground the face of the spacer prior to mounting the arbor so something a bit trickier must be going on.)

    Bob.

    You are correct again Bob, the arbor is pulled back against the fixture with a 16mm drawbar made from allthread which inturn pulls the fixture against the flat face of the workhead spindle. The home made eye nut and pin were used to hold the fixture for grinding the ends.

    Fantastic stuff Techo. I'm storing all these tricks away for that rainy day!

    Thanks Bob, on a side note, did you end up making the Over/Under attachment for your Hommel Werke Height Micrometer.

    Lex.

    It's still on the list Lex.

    I'm a bit daunted by the spring clip. Any suggestions as to how to make it given that Hommel probably would have used a press to achieve its curved form?

    Bob.

    It would be a bit awkward to make Bob. I guess you could try making one from annealed spring steel and then heat treating it.
