Here you can see the completed threads done by the machine.  Taper BSP thread to fit into the 1” Worchester ball valve.  The Swagelok fitting has a straight thread and I wasn't sure whether to use a straight or taper thread, so threaded both ends of the bar, one taper, one straight.  I’ve since found out from Swagelok that there is a copper gasket that I need to seal the straight thread at the base.  I feel this should have been included with the fitting, but anyway, I’ve just ordered 2 of those and I will fit the straight thread.  Copper gasket part number CU-8-RG-2.
