I have a well used pallet stacker that always comes in handy. It appears to have had a hard life from the previous owners and the brackets holding the rear castors are canted out at a bit of an angle. I would like to get these straightened but I don't have gas. My arc welding isn't too bad. Can someone suggest an easy way to get these straightened without cutting them off? I have considered grinding a vee, bending, then welding possibly with some reinforcement.
