    Another pair of horn to compression driver adapter rings 1.5" Vitavox etc.
    They are very popular these

    The 4 horn fitting threads are the proper vintage 1/4" UNC, unlike others you can get elsewhere.

    Seen here with the S2 throat adapter part screwed in to the upper one to test for perfect fit.

    Polished brass tonearm pod for 12" arm.

    Another handcrafted armpod in brass this time and with a 1" thick ebony armboard.
    Again cast solid lead filled for mass, adjustable feet. These armpods really are heavy/solid and do not move once placed.
    The polished brass adds a nice contrast to the ebony.
    This one will be fitted with a Schick 12" arm and is on it's way to Singapore.

    Here's the first of the SME style adjustable / sliding arm collar and bases I made that was always destined to be chromed all finished.

    Moving home and workshop (from Surrey to the New Forest) delayed my putting pics up here.

    Came out nicely.






    I've set up the workshop now and busy making armboards and many things hifi.

    Having moved house and workshop and been busy creating mostly armboards recently, it's time for an update.

    Here is the latest crop.

    A pair of SL-1210 ebony armboards with SME arm fitting - bound for the USA



    SL-1210 armboard in Ebony for Mikro-Seiki arm with on board rest mounting



    SL-1210 armboard in Ebony for a Jelco / Ammonite uprated armbase - For Singapore this one.



    A spindle reduction job so that a perspex disc could be fitted over the spindle end





    Lacquered finished armboard for a JVC QL-50 deck. Had to be very accurately made to a template / customer measurements, and with recessed turned nylon bolt mounts - for Canada this one.



    SL-1210 armboard in Ebony for uprated Ammonite armbase / Jelco - For the USA



    SL-1210 Ebony for a Dynavector DV-505 arm - For New Zealand this one.

    A little timeout from the many projects I have on the go for some customer feedback :-


    This was for an armboard for customer in Singapore

    "Hi Steve:

    Finally had time to install the armboard.

    Fits perfectly. Attached are some pics.

    Thanks again for your wonderful product and service."

    It's always nice to hear how things have gone and see the installation of the things I make in use. Getting some lovely pics of the deck and arm fitted are a bonus









    Here's some feedback from the customer for the bespoke AT armlift and rest I made in polished stainless steel, and an extra heavy
    counterweight too.

    Steve,

    Just a brief “thank you” note. I’ve been listening to the ATP-12t with the extra weight & arm rest/lift
    and am very happy. I’m using Miyajima Premium Be mono cartridge in a heavy Fidelity Research FR-S/3
    headshell and the combinations requires the extra weight. Mono records sound great with this.
    Thanks again!

    Pics of the lift and on deck.

    Steve,

    Default Latest armboards, record puck, counterweigh, spacer and WAF Najda DSP X/O build

    More interesting projects

    An ARS-1 ebony armboard mound for the States



    Ebony headshell spacer & counterweight for an SL-1210 also in the States







    A brass / ebony record weight puck bound for Spain. Don't worry, there is a centred hole for the spindle - just not in the felt in that photo





    Shown here with an armboard for the same customer



    More Flanges for Bob



    Something a little different - A WAF Najda 4 Channel DSP DAC / ADC, X/O with WaveIO USB -> I2S input.

    The Najda board and WaveIO are complete but very much build into a case yourself project items. The case was CNC machined to ensure good fit and looks - Thanks to Pete and Wal for help on the case.
    This one is fitted full with Burson OP-amps and a very nice OLED display..









    Here's a nice ebony one for Scotland - for a Mission 774



    I've lots more on the go, so watch this space.

    Default More armboards for the mighty SL-1210 MKII and MKV

    First one is an African Blackwood, for an Ammonite base / Jelco 750 arm.



    In a different light



    This Ebony one is for the Mission 774 arm. It's a much bigger armbase than the SME offerings.







    I have a satin black armpod and a valve amp protective valve cage on the go ready soon

    Here's the latest ones

    First up is an armpod all in black to match its surroundings.
    This one was not as tall as the others so it can be used on a standard height plinth / platter turntable. The cast lead filling means it is plenty
    heavy enough to not be moving.
    Ebony armboard (of course) and black lacquered steel tube body. Feet also in black and smooth this time,

    The arm to be fitted is a Rega RB303.

    Here it is in the customers installation





    Under construction














    Here's another AT 12T armlift holder. It's a great arm but manual cueing perhaps puts some
    off. Here is a besoke solution make from solid Stainless steel.
    Highly polished to match the arm it will mount on.







    A one-off this one - a cage to keep little fingers away from
    hot KT88 tubes. Welded steel construction with wire mesh fitted.
    Carefully done so there are no sharp edges.
    This took a bit of prototyping to get something solid.






    Here's a brass balancing weight for a tonearm.
