    Nothing's cheaper than MFJ unless you DIY from scratch; it's sort of the Dollar Tree of hamdom.

    Cheaper?

    I think impossible, unless you're handy with tools and just make it all yourself from scrap aluminum or steel plate.

    Yep, I guess you're right. Just got a 1/4" aluminum plate and I'll figure it out.

    Looks like part of a traction array I used to setup on a hospital bed when I was working in Orthopedics.

    So did you try a hospital? :D


    I don't know, $39 bucks is a lot cheaper than Zimmer traction equipment though. I don't think it can get any cheaper than MFJ.

    I've made something like that, using 1" plate, to fit a 2.375" OD round mast.
    The plate MFJ used appears to be about twice as thick as the hardware OD:

    Use a harder alloy, so it won't take a set (and then loosen).
    I suggest AT LEAST 1/4" hardware (5/16" or 3/8" would be better).
    Stainless steel hardware w/ antiseize compound is also a good idea.

    I'd think anything in the "hospital supplies" catalog would be a whole lot more expensive no matter what it is. Kinda like "marine" supplies for boats, where a sink faucet costs $400 and the same thing from Home Depot for "home supplies" is $79.:p

    My company has sold electronic equipment to "hospital equipment" companies, who integrate our stuff into their stuff and then sell it as a complete system doing something or other (such as the digital recorders for C-T scan or MRI machines). The "requirements" list was pretty daunting. Polished stainless steel for everything including chassis where we normally used aluminum or galvanized steel, etc. PITA.

    :p <---- okay so why can't I delete this ? Lol

    I used to see the costs of some hospital equipment and it's absolutely ridiculous.

    For example a basic Hill-Rom hospital stretcher we used in the ER costs more than a brand new car!
