    If you've searched the archives I expect you've already seen
    references to the "$200 DIY Drawbench" page at my website
    (http://www.touchmetal.com/workshop/200drawbench.html). 

    FWIW the winch I used there --a Fulton T600-- has the following
    stamped on the side of it: 

    MAX LINE PULL
    600 LBS 1st Layer
    300 LBS Full Drum

    I've drawn wire as large as 4mm on a side with it and the winch never
    even noticed the strain. 

    I did replace the original cable with "1 TON" seatbelt strapping
    material because I found the cable too springy. In the end the
    strapping has proven much more satisfactory, for this and other
    reasons. 

    As to the "required" timber size I couldn't tell you. I started with
    a doubled up 2x4 and it seemed fine albeit ugly. I later obtained a
    6x4 fir timber which, like the winch, has been totally unphased by
    anything I've ever drawn. 

    My guess is that it's over-kill on both counts but for $30 who's
    counting? 

Cheers,
