Early A Headman headers

With CNC tube benders, you just run the header profile program and feed it tube. Then have the labor weld it to the flanges. One of my customers has an automated tube bender: Feed it a piece of tube, it runs it in and slides in a flexible cable with a bunch of preloaded disks that match the ID of the tube stacked on it. It moves the clamp down the tube where it needs to be bent and the disks follow it. The tube starts to bend right over the disks so they prevent the tube from kinking and then right before the bend is done, the disks get pulled out (with great force) and the bend is complete. Its all automated, really cool to watch.
