    The Tannoy GRF replica cabs all finished and under test.
    As always 24 & 21mm birch plywood used throughout.
    These feature the tear drop baffle and are bi-wired for true active amping, should the fancy take the new owner.

    A little update on a Reed armboard I made a while ago.

    Here it is mounted on the customer's deck.
    It's nice to see where they end up

    Replacement Stainless Steel anti skate weights 5g and 3g and mounting rod for the mighty Fidelity Research FR64s classic Tonearm.
    I've been commissioned to make the whole anti skate assembly so more crafting to come.

    Hehe
    Thanks for the interest.

    The lathe I do the machining of ebony and African Blackwood armboard on is indeed a metalworking lathe.
    I use Tungsten Carbide indexed cutting tools.
    The lathe is a 1940s Southbend all the way from Indiana USA.
    Shipped over here no doubt dodged some U-boats as part of the machinery the USA could send us, but not actual weapons before they came into the conflict..

    Anyway, it's a 9" swing and does a nice job.

    I have a smaller precision lathe from Warco for smaller parts like the stainless steel counterweights, anti skate weights etc.
    That's great because it has electronic variable speed from very slow with good torque to 2750rpm, and goes on reverse too.

    I fit attachments to the lathes for milling. I don't actually do much of that though..

    Both lathes are set up with the lead screw to cut 16 Threads Per Inch required for the Vitavox screw on adapter rings. I make a fair few of those..

    Here's more progress on the Fidelity Research FR64s anti skate assembly I was asked to make.

    I have turned the rotational cylinder, had 4 drillings and made the counterbalance cone.
    Trial assembled so far as I have to wait for the rare threaded bolt (an old bicycle spoke thread I cannot cut) needed to attach it to the arm.
    Once I've got that I can do the final machining, clean up/polish and test it on the arm.

    Labour of love..

    Test assembled





    Turning the small counterbalance cone.
