The inside width of bend is 2 1/4". I made a few mock ups with trapping wire to see how I should do the bends.
First bend from shaft is 90 degrees and easy to do with vise.
The deep bend- A spray paint can is 2 1/2" and will work. I had some firewood nearby and pick above piece,2 1/4", which worked best for bend.
RBH says I have a few golf clubs that (at times) I wouldn't mind using for something like that!
Years ago, I cut off head of golf clubs for walking sticks for wife and I. They are still in good shape.
