exactly...it doesn't take a lot of heat to make it flow easier.....aluminum will start to melt at around 1100º F
Here's a bender I made for doing 5/8" AC hard lines...the Rigid bender makes a 5" diameter....mine makes a much tighter 3"
The bend in the last picture is a cold bend.....
BTW: the hole in the base serves no purpose, it was just already in the scrap piece I used....
