How do you make a basket twist?
Start simple take 4 rods weld the tips together both ends
Heat the bundle uniformly and clamp one end in the vise
Twist tight one direction
Then untwist a bit and the basket should open up
You may have to tap one end a bit to get it to open up as well.
You may have to use a pry tool to get them evenly spaced.
Large globe shaped baskets are much more work but can be made around a form then welded then twisted.
Experiment a bit and see what you get.
Is to split the bar from both sides instead of welding. this is nicer but much more work.
