Flattening a metal tube, HELP!!

[GarageGuy]

I used a die and torched one side of the tube and smashed it rather quickly in the die…I wish you a very Good Luck.

I was thinking heat would help too. DOM is pretty strong, and to get it to look like that without cracking would require a torch. Slitting the sides of the tube where it will be flattened may help too, then grinding the profile needed and drilling.
