    tiguan,
    Great job on your turntable! After seeing yours I should have gone with wood for mine.
    How about the sound quality compared to the original?
    What cartridge are you using?
    What is the top surface?
    Tell us more about how it was fabricated, please!
    Very nice!!!

    It was a very time consuming period for me. When I saw yours I thought that I could do similar to yours more cnc machine less me. Smile Smile

    At this link you shall find more detailed photos from start...
    https://picasaweb.google.com/105041940468126077194/DIYTURNTABLE02?authuser=0&feat=directlink

    Body established from 4 layers of birch ply 18 mm. Total thickness 72 mm. 2 layers between  the upper and lower layers are cut inside making frame.
    Then upper 3 layers glued all together before closing lower layer filled with isophaltic resin with lead fill.
    Feets for upper body are sorbothane , lower body Sorbothane spike combination.
    Arm board is made from mpingo tree. Both lower and upper bodies upper surface veneered with 2 mm thick ebony frame and iroko burl sheets.
    Later on made natural french polishing. (The most time consuming stage) just this polishing stage took 2 weeks, my first french polishing experience.total 60 layers of polishing.

    My cartridge is denon  dl103r as driving with diy le pacific phono pre and Bobs Device SUT.
    Most significant improvement was on lower frequencies. Deeper, seperated with more definition.
    At the start upper frequencies were not good. But after 3 months I realised it was due to tone arm wire burning period. While making turntable I changed internal wire making one piece till phono pre.

    tiguan,
    thanks for posting about your turntable. You have done an excellent job and just wish you were closer so I could hear it in person.. Some day I will Visit Istanbul!
    Do the craftsmen there still make those outstanding cymblas?
    Well done!
    Bob.

    Wow, Tiguan - 60 rounds of French Polishing, how are your wrists and forearms?? (I do a lot of rubbed oil finishes, but never more than maybe 12-15 layers and usually have a claw hand for a couple weeks after completion)

    Congrats, that's a beauty, love the burl veneer. Did you cut your inner cavity laminations with a pattern bit?

    It was a very difficult period Smile but I did not hurry up.
    I made a tool to make adjacent edges even. To sandpaper will lool a photo for that.

    tiguan,
    thanks for the additional info.
    From the data it looks like the material you used is rather ideal.

    I can certainly appreciate the effort put in to the polishing.



    Thanks again!
    Bob.
