Hi citroelf, it looks like you've got all the info you need to do it! :)

Just one more thing to mention - to get the same kind of shape as your original one where the center part is untwisted, you'll probably want to use the Twist command 2 times with the "Limit to axis" option turned on so that you can only twist the end parts of the bar.

So then for each twist you would pick points for the twist axis like this, with the first point being towards the center of your shape:



Then repeat that twist on the other side, or I guess you can just mirror it and boolean union the 2 mirrored pieces together.

But anyway, you'll probably want to put your twist axis points to one side of the object and then use "Limit to axis" so that the part of the object outside the axis zone does not get twisted.
