584.0. "Help on straightening Stainless Tubing" by LEVERS::SWEET (Capt. Codfish...GW Fishing Team) Tue Jan 09 1990 14:25

    It took me most of last summer to realize the reason my Bimini
    Top is not taught accross the top is that the arms are bent instead
    of straight. I am not sure how the arms got bent (they came that
    way) but know I want to straighten them out. They are about 1"
    tubular stainless.  Any suggestions or know who does this kind of
    work?

	This might sound a little strange, but try a  "GOOD"  bicycle 
shop, the kind that can straighten frames, maybe a frame builder.

	Alternatively, try tightening the back straps, assuming the
design is similar to my SeaRay.

584.2TRY IT YOURSELF FIRSTUSCTR2::HWYDOMTue Jan 09 1990 16:1819
    Depending on the overall length, the gauge of the tubing, and the 
    severity of the bend you're trying to straighten, you may be able
    to do it yourself.  The secret is to prevent damaging the tubing
    by correcting the bend all in one place.
    
    Fill the tubing with sand from end to end and gradually applying
    pressure at different points will allow overall straightening without
    damage.  The pressure of the sand will insure the tubing retains
    it's round shape, while at the same time there is enough flexibility
    to straighten by applying pressure at multiple points against the
    bend.  Straighten it gradually by applying pressure along the whole
    length of the tube opposite the bend.  When you're finished simply
    empty out the sand and reassemble.
                                                   
    Looks like from your diagram (no apparent severe angles to straighten)
    this could work.
    
    good luck

re .3	Hmmm, yezzzz.... I  *_DO_*  have some tubing benders somewhere 
around the garage - they're just big springs that perform the same 
function as filling the tubes with sand, which is to prevent kinking.  
I may not have anything quite big enough though, if the ends of the 
tubes are sealed you would need a spring with an internal diameter a 
little larger than the tube you're trying to straighten - that's large 
and will be fairly stiff itself.  It would be easier to fit a smaller 
spring inside the tube, less stiff and it would be easier to see the 
progress.  Garage door springs or attic stair springs, something 
around that size for 1 inch i/d.
