Another week of steady but unspectacular progress with the J72 as we pass from a dismantling to a refurbishment and repair phase.
Neal has started to carry out the various “Form K” inspections in order to determine what work is required to make the various dismantled components serviceable again.
Arthur and John spent Monday evening cleaning out the lathe sump, and after Tim delivered three new V belts on Thursday, the lathe is now in much better condition and Arthur is well on with the production of the K1 superheater cups.
On Thursday the spring hanger pivot forgings were cleaned up and polished ready for dye penetration testing. If these are found to be crack free then it is intended that these will be reamed out and bushed. Steve continued servicing one of the injectors, though one seat remains to be cut. Allan, Roy, Colin and Hughie continued cleaning the J72 frames and wheels. Dave finished the side valve protective “clogs”. Derek finished cleaning the carbon from one of the K1 piston valves and has started work on the other. I spent the day finishing the prep work prior to varnishing the woodwork in the J72 cab roof.
So, thanks everybody, let’s keep up the momentum.
