Greetings all:

    This is mostly just a question based on a couple of comments in the 
    rolling mill thread about drawbenches. 

    Several of the shops I've been in, as well as a couple of rigs I've 
    built myself have made a drawbench simply by attaching a reduction 
    clamping system to one end of any random strong bench/tabletop in
    the  shop, with either a set of pins or a vise at the other end. 
    When not  being a drawbench, it's just a normal tabletop.  The
    reduction system  just sits at the end of the table, out of the way
    until needed, and  the vise is just a vise, until it becomes part of
    the drawbench.  As  I said, I've seen rigs like that in more than
    one shop, and I've  built two of them myself. (Probably about to
    build a third.) I get the sense from the 'unaffordable luxury'
    comments in this  thread that this isn't a common trick?  Has
    anybody else seen a rig  like that? 

    As a side note, someone asked about whether having a rolling mill 
    with wire wheels made it un-necessary to have drawplates.  No, 
    regrettably, you still need the drawplates.  Rolling mills don't do 
    round wire, and those that do, don't do it well.  (They still leave 
    flanges.)  You'll note that the square wire has 2 corners beveled, 
    rather than true square, and flanges on the other two.  (Or all four
     corners beveled if you roll your wire properly.)  However, they're 
    absolutely *great* for breaking raw ingots down into something close
     to the final drawn dimensions.  Use the mill to get close, and then
     draw from there.  Much faster. 

    Besides, how else will you get star shaped wire? 

Regards,
Brian Meek.
