Try a shallower angle. I think 10\* is prefered, it looks like you were able to do a 90\* in 4 cuts, should take you 9 cuts.

Some simple math should let you know how much to cut on the small and large side…

i’m just sayin. as i said, make the short side longer (less angle).

You want about a 3-4" inside bend radius.

Try sucking at it less.

these diagrams i came up with work well also …

diameters listed down the left hand side are the inside diameters of the bends, just like mandrel bends are measured

possible angles with that segment size are listed across the top

angle of the cuts to make those size segments are listed below that, the angels listed apply to all the segments directly below it

the measurements listed next to each bend are the short side and long side length to achieve the diameters listed on the left

any questions, or if you want different pipe sizes or inside diameters drawn up, just lemme know

sometimes the best way to do something yourself, is to call someone else

in your case, you would call me …
