Another report which says slow but steady progress with the J72.
Today, Arthur opened up as my vehicles needed MOT, and after I had delivered them I had to get on my bike. As I passed the phone it rang. “Is that St Tereasa’s Care Home?” Humm, I know that the workforce is aging, but …
Arthur has completed the K1 superheater cups. These are now on the goods out pallet; Arthur asks “Who should I invoice?” Steve Johnson stripped the paint from 2 of the K1 sand pipes today in readiness for repair and repainting.
The spring hanger pivots cleaned and dye penetration tested by Tim Williamson. As they were all OK, Neal took them all to M-Machine on Monday for reaming and bushing.
The valve buckles have been cleaned and are ready for dye penetration testing. The connecting rods and eccentric rods had paint stripped from their ends in preparation for NDT today.
The studs for cylinder/valve cover were found and inserted. This week Tim cleaned up the area , ran a tap down the three holes where studs had been removed and through all the nuts. However, we re-discovered that we haven’t got a 7/8” BSW die nut. Re-discovered in that memories of doing this job 3 years ago were jogged. Arthur managed to turn an old worn sand pipe securing nut from the scrap under the work bench to hold a plain die, Tim managed to use the hexagonal end of this to run the die down all of the studs. Well done Arthur, you’re a star. However we really ought to obtain a proper 7/8” BSW die nut.
Andy Bell and Steve Gibson came to the conclusion that the jaws do not engage properly into the chuck of the new valve seat cutter. Steve is took the kit to Carnforth on Saturday to compare with Johnny’s cutters. Opinion seems to be that the jaw thread is different to that in the chuck . The kit has been returned for Neal Woods to look at. Andy is proposing turning special purpose cutter holder in order to make progress with his valve seats.
Steve Gibson has now completed work on the 2 injectors. He, John Crabtree, Tim and Steve Johnson are now well on with the servicing of the brass bits.
Special thanks to Allan Wilson, Dave Wright and Colin Smith who have continued the thankless task of cleaning the loco frames and wheels. The end looks in sight now.
The internal cab roof has now had 3 coats of varnish. It can harden over the festive season. The residual fitting have been removed from the cab’s internal walls in readiness for rubbing down and painting in the new year.
Richard Pearson visited last Thursday in his new role with the A1/P2 organisation.
We were not so indulgent as the Grosmont folks. We gathered by the fire were for tea and mince pies (both Thursdays).
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.
On Monday Neal Woods spent some time with a micrometer measuring various things, and explaining to myself, Steve Hyman and Andy Lowes and Arthur what needed doing next. Andy Lowes cleaned one K1 piston valves. Arthur continued with his production line on the lathe.
Today Mark O’Brien, NYMR boilersmith, arrived and undertook an initial examination of the boiler. Roy Marshall took notes. A report will be produced in due course.
Mark brought the NYMR universal tyre gauges. James Pearcy and Tim Williamson measured the profiles and used the ultrasonic thickness gauge to measure tyre depth. Good news I understand.
The chairman came, initially to meet Tim Gardom from the interpretation plan consultants TGAC. TGAC are working for the Tees Valley Combined Authority’s Railway Heritage Masterplan project.
Steve Hyman called in to drop off a roll of valve packing. Derek Shorton and Dave Wright continued with the decarboning of the K1 piston valves. Tim continued servicing the brass bits. After lunch, Chris, Roy and Colin Smith continued the cleaning of the frames and wheels. Dave Wright is making wooden slippers for the valves side valves to protect them from harm. I continued preparing the woodwork of the cab roof for varnishing.
The machinists have been busy again and have completely filled the swarf bin. Maurice has finished turning the various pins for axle boxes. Arthur has a production line running producing K1 superheater cups. There a big hexagonal bar from M-Machine to be turned into K1 crown stay nuts. Tim has taken one good lathe drive belt from the large lathe in order to see if he can obtain three of the same size from a source at Leeming Bar. As that lathe will not be usable until Tim returnes next Thursday, Arthur and John are going to attempt to drain and clear the lathe’s sump on Monday evening.
We are out of gritty soap downstairs. Dave is going to attempt to obtain some from ARCO on Portrack lane. Monday night people may have to go home with dirty hands or find the soap upstairs.
Good progress, but with no spectacular changes to be seen. Well done folks.
Maurice Burns and Ian Storey visited last week and inspected the back head and the smokebox, trying to decide how the longitudinal stays worked and were inserted into the boiler. They thought that the smokebox nuts ought to be removable and that the stay might then hammer or screw out. Maurice suggested applying some heat to the centre nut and trying removal.
After lunch the smoke box end nut on the central stay was heated and quite easily removed.
Hammering did not move the stay, but the whole stay could be turned using a socket on the back head end nut. Arthur continued twisting stay with the socket. Slowly, after 11 rotations, an inch of threaded stay had emerged. (Now we know why the nuts are welded at the back head end.) A little more turning and the stay narrowed, was free, and could be drawn out beyond the dome by hand. The weight of the stay is supported by a cross member towards the fire box end of the barrel.
Out went the shout for the Hartlepool monkey, but Roy was somewhat reluctant to squeeze between the stays.
On the assumption that all of the stays were fitted in the same way, Harry started to warm the next smokebox nut. Then, all ended in a damp squib as the Oxygen ran out. Too late in the day to fetch new cylinder. The new cylinder will have to wait until next week.
During the day the trap door in the tower was sealed. At one stage a rain of fresh firewood descended.
On Monday, several more stays were withdrawn.
After withdrawal of two more rather stubborn stays today, Arthur entered the boiler. He managed to remove the J pipe and in the process covered himself with dirt. We have yet to hear whether he was allowed onto the bus to make his way home.
Whilst access to the boiler was the big event, others continued with machining, servicing the brass bits, cutting up the supply of firewood, storing parts, cleaning the loco, painting components, cleaning the building, and of course, making our many cups of tea. Steve Johnson joined us for the first time for a few months today and remarked upon how much had changed. Let’s keep up the momentum.
Another good week.
Not a lot done on Monday night as Martin and Andy held their first aid session with the Monday regulars. Arthur and John continued with the springs. Neal provided more advice. I got a bit more paint on some K1 bits. We were visited by Paul who has borrowed a couple of needle guns to clean up the K1 boiler.
Today we had a good turnout again. Harry and Steve managed to extract the rings which were jammed in the piston grooves; then for an encore managed to remove the slide valves. John and Tim worked their way through brass bits, dealing with the gauge valves. Roy Colin and Hugh continued cleaning the loco, Derek continued with the boiler. The machinists were all busy whilst Colin and myself managed to paint a few things and Allan finished off the brass around the K1 windows.
The parts washer was bailed out into waste paraffin drums. On inspection we appear to have lost the work shelf. The device has a current PAT label. However, when I touched the on/off switch it disintegrated. I wonder if it is worth renovating this device. It should NOT be used in its present condition.
We had a visit from John Midcalf who has handed me the kit for the social meeting tomorrow. He’s participating in the velocipede gala on NYMR and may not be able to return to Darlington early enough to set up for the meeting. However, the expected visit of Ian Storey didn’t occur; the K1 lubricator linkage is still on the bench.
We are approaching the point where we have dismantled as much as we can. Much of the future work will depend upon the result of inspections which need to take place soon. However, there is work which just requires us to work through servicing components which we have removed, and making them ready for reassembly.

An attendance of 20 today including Bryan Orange and 3 juniors, plus John Crabtree a new starter who has worked on Strathspey Railway in past.
Much of the morning was taken up with Martin Lloyd and Andy’s first aid (mainly CPR) course. We had to split into 2 sessions as the mess room capacity was limited. This led to some second session attendees champing for their morning tea. The course was very worthwhile. Thanks Martin and Andy.
Steve and Harry got the cross heads split and the pistons extracted. The rings are jammed in the grooves. Not known whether they were like that in service.
Tim and Roy cleaned up all of the axle box bits and placed them in the appropriate bowls. The underkeeps have been removed and are in a plastic sack. The oil trays held a lot of water. One tray (RD?) has a crack/repair which should be examined. Tim brought the 2 spare springs plus the NELPG tools from Leeming. John and Arthur got on with preparing the ends for dye penetration testing.
John Crabtree continued with the preparation of the cab roof. Dave and Derek continued to brush down the boiler, Colin Smith and Allan painted first gloss onto some of the K1 components whilst Colin Bowman continued cleaning the loco frames.
Trevor Wolford came in the morning to do his Dick van Dyke thing with the fire. He showed us the quarantined chains and requested that BV tested and advised. Mid-afternoon we had the company of Terry Newman and Steve Hyman, followed a little later by a party of about 5 visitors who came to look around.

13 signed the book today, plus a visit from Ian Pardy and Stuart Dennis from NYMR. We also had a visits from Bob Grey and Trevor Wilford.
With the K1 components:
- Allan Wilson has managed to scrape the old varnish off three of the windows
- Steve Gibson welded the joints in one of the steam pipe covers and Harry dressed the welds with a grinder.
- Colin Smith stripped the tea tray and steam heat gauge bracket
All K1 components other than the seats and windows are in primer.
On the J72:
- Derek and Dave took a break from the cab roof work this week and continued cleaning down the boiler.
- Arthur and John continued polishing the spring hanger loops which are welded in order to facilitate dye penetration tests. However …
- Steve and Harry started to prepare to split the crossheads, but discovered that the dummy gudgeon pin was missing. So, Arthur was asked to turn a replacement.
- Maurice (Bell) prepared to turn the new hanger pins. He has completed the set of oil tray retaining pins last week.
- Ian and Stuart arrived in the new NYMR truck. Steve and Harry assisted them with the axle boxes and measurements John and I helped load the boxes onto the truck using the engine hoist borrowed from the A1 trust.
- Colin Bowman continued cleaning the frames.
Since this is likely to be the final good day of the year, I scraped and painted the front door before the wood gets wet. I managed to spill some paint on the floor whilst driving the paint stirrer with a drill. I suppose that it is now floor paint!
We were visited today by John Crabtree, a potential new member who is a retired steam fitter/machinist previously employed on Strathspey Railway. He has come to live in Thirsk. Arthur showed him around.
Tim Williamson has volunteered to bring the 2 spare springs from Wensleydale next week for cleaning and testing.
Much tea drunk, and a warm fire to gather around again.

We arrived to find 2 dead pigeons on the doorstep. Is this a bad omen? A sign of metaphysical death?
Anyway, after Arthur had tossed the 2 corpses onto the grass, in the hope that the local cats would take them home, the usual suspects set to work. Steve and Harry managed to remove the front buffer beam and the piston and valve covers. Derek and Dave continued with the cab roof, to be joined by Colin Smith after lunch. Allan and Colin Bowman continued cleaning loco frames. A new volunteer, Maurice Bell arrived. He’s a retired machinist. He helped John and Arthur with the springs and hangers. I had a trip to to M-Machine to pick up some steel bar for replacement pins. Peter cleaned up the K1 cowls and steam gauge frame. One cowl will need a bit of welding before painting.
Derek Norris called in during the afternoon.
A productive day.
Another week at Hopetown. Arthur, John and Nigel had been there on Monday evening to progress machining and a few other small jobs. Today started with the hunt for a substitute for theT2 steam brake isolation valve – see yesterday’s T2 report. Unlike all of our other locomotives, the cab steam services for the J72 are not fed from a backhead manifold. Nothing in the brass store seemed remotely like the size of valve required. I phoned Bill at about 10:00 to break the bad news.
Colin Smith, in dust mask and face shield, dressed the chips in the paintwork of the inner frames. More correctly he dressed the rust beneath where the paint had been chipped. Allan Wilson, after making morning tea for us all, cleaned the dust Colin had created from the surfaces and later I dabbed a bit of anticorrosive primer onto these spots.
Harry Sams has finished making a wooden template for the spark arrestor. If this design is approved then we can commission the construction of the real thing.
Maurice Bell, John, Jones and Arthur Jenkins continued machining the loco springs and spring hangers.
Derek Shorton has returned from his trip to Wilderswil and the lines to Schynige Platte and Grindelwald. He’d been over the line to Kleine Scheidegg and Wengen, and had caught the connection to Jungfraujoch. Back at Hopetown we had remembered his old trade and found him a float for screeding some bad parts of the walkways. We’ve obtained some epoxy sealant and some epoxy self-levelling screed to repair the worst bits before painting. Derek suggested that we needed to (wire) brush out some of the oil covered surface cement, and set about this with a cup brush. He later found a needle gun was quicker. In the afternoon Hugh Pannel arrived and brought in the needle artillery. There was a lot of shouting about dust and noise. I just hope that we haven’t removed too much of the surface.
Just before lunch, Roy Marshall and Norman Crockit arrived. Roy took the open day cupboard key which Norman had brought in to the locksmith for duplication. Unfortunately no blanks, so Roy came back with a new lock and keys which he distributed appropriately. Roy and Norman both left not long after lunch time.

We had a major step forward on Thursday when Andrew Goodman and RSS lifted the locomotive chassis and the wheels were rolled out. See pictures by Peter Giroux – there’s 58 good photos in the collection.
