1. A tubing bender device comprising:
a frame having a handle, a ratchet mechanism engaged to a slide rod and said handle, and a frame notch proximate to an outer end of said frame;
said frame having a first bending configuration further comprising a bending mandrel, said bending mandrel having a first bracket receiving aperture releasably engaged to said slide rod, and said frame having a cross bow bar support releasably engaged to said frame notch, said cross bow bar support comprising a plurality of die heads releasably engaged to said cross bow bar support, said die heads having a degree of revolution relative to said cross bow bar support, and a plurality of repositionable die heads releasably engaged to said cross bow bar support, said repositionable die heads having said degree of revolution relative to said cross bow bar support and a degree of rotation relative to said cross bow bar support, each of said die heads having at least one die head pipe receiving recess having a radius dimension, and each of said repositionable die heads having at least one repositionable die head pipe receiving recess having a radius dimension different from said radius dimension of said die head pipe receiving recess, wherein said die heads or said die heads and said repositionable die heads are aligned relative to said bending mandrel in an first configuration operative position, said die heads or said die heads and said repositionable die heads and said bending mandrel being constructed and arranged for bending a pipe in a first bending direction, and further wherein said repositionable die heads are rotated downwardly below said cross bow bar support in a first configuration non-operative position; and
said frame having a second bending configuration comprising a first support bracket releasably engaged to said slide rod, said cross bow bar support being releasably engaged to said first support bracket, a second support bracket releasably engaged to said frame notch, said bending mandrel being releasably engaged to said second support bracket, wherein said die heads or said die heads and said repositionable die heads are aligned relative to said bending mandrel in an second configuration operative position, said die heads or said die heads and said repositionable die heads and said bending mandrel being constructed and arranged for bending said pipe in a second bending direction, said second bending direction being opposite to said first bending direction, wherein said repositionable die heads are rotated upwardly above said cross bow bar support in a second configuration non-operative position.
