Adjustable coiled tube straightening tool

Hi All

I have finally got around to using the coil straightening jig I made, it must be a few years back now.

The coil was initially uncoiled by hand for roughly 3' and then cut off at 27,1/4". Which would be enough material to make three 9" fire tubes per length. The 3/8" diameter copper was then fed back and forth through the jig and and rotated at the same time until straight. The tube came out really nice so really pleased with the homemade jig.

Lengths nice and straight, ready to be cut in to three pieces to make boiler fire tubes.
