Sand bending

Thought I would put this post up as I gave it a go to make a bend piece up for the oil pickup/spray bar I’m modifying.
As you can see when I attempted the (very tight) additional 90deg bend things went south.
I watched a couple of videos on it and found packing the sand hard worked best.
I’ll keep it in the arsenal though. You need to bend very slowly and of course have whole area very red.
