    Arrow Speedy Steve's custom-made counterweight balance and armboard service!

    Guys,

    Anyone looking for a custom-made brass C/W, perhaps for balancing out a heavy headshell being used with a DL-103, or maybe just making an existing arm look sexier - whatever the reason, Steve can help

    Here are the details (taken from this thread in The Drawing Board: http://theartofsound.net/forum/showt...188#post119188)

    These would have a simple grubscrew and slide on unless there's a spiral carrier that lets you slide a different weight on like the Acos PL-71 arm does...

    So if you want a weight let me know :
    - diameter size inner
    - diameter size outer
    - what mass.

    I can then work out how much needed. Perhaps there is a cheat sheet on the web for this. I only really want to use brass as it's nice to machine - forget titanium. Gold at your expense and I would keep the filings and off cut

    I will see what bar stock I have or have to order more.

    I tend to just finish with fine emery cloth as lifes too short for mirror finishing polishing and unless you lacquer they tarnish. The satin finish you see in the pics lasts for at least months like that.
    Lacquering would be possible too

    Could certainly do normal sizes for 25 + postage.
    PM Steve if interested (email details to follow)

    Interesting!

    I am in need of a heavy counterweight for my Technics 1210 to counterbalance my very heavy re-bodied Denon 103.

    But ... I don't have the means to weigh the thing accurately - all I know is that it takes four 2p pieces blu-tacked together and on to the end of the standard Techie c/w to make it balance!

    Any ideas how I can specify and quantify my requirements so Steve knows what to make?

    Get one of these http://direct.asda.com/Salter-Disc-K...efault,pd.html and you'll at least know how heavy the counterweight needs to be.

    Thanks for that, Chris - a visit to Asda may be in my near future.

    You're welcome Jerry.
    When you say balanced, do you mean at equilibrium, or do you mean with VTF applied ?
    If at equilibrium, is the counterweight at the end of its' rearward travel ? - you may be able to factor in some additional mass to the counterweight to enable you to move the counterweight nearer to the pivot point and thus lower the interia of the arm assembly and also lower the effective mass slightly.
    In my experience the closer that weight is to the pivot point the better the situation is.

    Aha! -thanks, Hamish.

    .... and how much does the standard Techie c/w weigh?
