Fortunately I have a compact bender which I have modified with a special die I had made by my favorite machinist (my dad). I built him a phase converter to run this lath, so I don’t mind getting some free work out of him. Being an electrician I am comfortable with bending tubing, although the oval shapes I am bending are nothing like anything I have done before. I’m learning as I go, one of the great things about doing things like this. I probably could have had the parts made, but where is the fun in that?
Here is what I'm using if anyone is interested.
