i need a place to host the pics and who wants to edit this
in this post ill explain how to bend perfect 90's and 45's.
some math you will need to know when laying out you bends. most benders radius is for the center line of the tube/pipe your bending. if its the out side radius minus half the tubes dim if its the in side radius add .
to figure out how much of the tube is takken up by the bend ie from the start of the bend to the end of bend is simple.
angle x radius x .01745.
so for a 90 bend with a 2.5 radius it would be
90x2.5x.01745 = 3.92625.
to figure out the center of the bend divide by 2.
to layout a 90 bend.
say from the start of the tube to the center line of the 90 bend you need 30 inches. just minus the radius from the dim mark the tube and bend. say you all ready have a 90 bend and you need another one after it. the center line to center line dim is 30. add half of the tube dim then minus the radius and that number will give you the point to mark on the tube if you comming from the out side of the tube.
any thing other then 90's you really need to layout on paper and know some math to make them work.
if you have a print its easy as pie .
