Got around to machine a shaping die today.
I changed the design of the die so it is only half a tube shaped at a time. I clamped the round part of the tube with a F clamp and put the die in the wise. I worked my way from the round center to the oval end slowly.
I will do the other end on Monday. Got kicked out of the workshop by the guard 7pm. Oh well...
the bend is a bit sharp. Next time I will try with an internal die in steel, turned on the 4 axis cnc. Edit: I think it is called an oval mandrel..
