I failed to see the testing machine, but the blacksmith's vice caught my eye! I almost bought one this past fall, but it had already been sold when I saw it. I did get a really nice 100 pound anvil. It is in mint condition, with a hot chisel for the hardy hole.
The wrap around I designed and built is patterned after a bending machine. I can't think of the name off the top of head, Oh yea, a Hossfeld bender. I can use different diameter mandrels and it is light enough I can check it as checked baggage when traveling. It uses people power to operate it, no jacks, pumps, just a long handle is all it takes. I have even bent samples of HY-80 with it. It took two of use to push/pull the handle, but it did the trick.
As you well know, API 1104 uses the same diameter mandrel for everything. AWS, ASME, and NAVSEA on the other hand required different mandrels for different thicknesses and different strength or elongation properties. So, several different mandrels must be stocked.
Calibrated? The tolerances for the bend diameters are pretty liberal. I can see calibration for the tensile testing apparatus, but not the bending machine.
