        You can buy mandrel bends from exhaust suppliers (specify tubing dia. 
radius of bend) then piece them together as required, although 1-1.5" od
might be outside their range.
        If it must be one piece try a sand bend.  Weld plate on one end of 
fill with casting sand or similar, weld plate on open end then heat and
bend as you described with vise.  
        Very sharp turns in tubing as small as you describe may be difficult to
achieve without some distortion, is there an alternative to steel tubing ?
