Just a brief update this week.

The last few days could have been better for the K1. While we have essentially finished the painting of the coupled wheels and frames and all but completed the replacement of the defective roof stay nuts, we found that the leak on the "J" pipe/steam pipe joint was due to a fracture in the "J" pipe. While this can be repaired it will have to be sent away. As it may save time by dropping the "J" pipe off for repair (to Derbyshire) if any one is available to do this on Monday or Tuesday next week then I would be very grateful to hear from you. The company car will be available for this If needed.

In addition to the problem with the "J" pipe the trial fitting of the ash pan revealed far more distortion than we anticipated. This distortion is not due to the work we have recently carried out but can only be attributable to the stress imposed upon it while in use. While it was not apparent at the time, the ash pan must have "relaxed" as it was released from the foundation ring.

The solution has been to effectively cut the ash pan in two. We did this yesterday and now have a satisfactory fit to the foundation ring. There is now, however, a one inch gap to fill between the front and middle hoppers.

In view of the delays caused and the additional work generated by the problems outlined above, coupled with the fact that we are already well behind schedule, there will be working parties every day except Friday next week. Other than possibly being needed to take the "J" pipe for repair the company car should be available if required.

Decent progress at Carnforth last week. One of us there Tuesday and Wednesday (increased to 2 late afternoon each day) five on Thursday, two on Friday, 4 on Saturday (boosted to 8 for an hour or two after the PTS course had finished) and 3 on Sunday.

After last week's successful hydraulic test the boiler was drained and prepared to be lifted onto it's side. This involved removing one or two bits so that nothing got damaged as the boiler went over. West Coast over saw the lift on Wednesday. This was done after the hired crane had reunited Scots Guardsman's boiler and frames. Our lift was straight forward and was completed early afternoon.

Since then all of the 60 defective roof stay nuts have been removed and about half replaced. The ash pan securing pins have all been cleaned ready for trial fitting of the refurbished ashpan, a start has been made on preparing the header for refitting the elements and the dome cover has been removed so that we can remove the "J" pipe (it was evident that the "J" pipe/steam pipe joint had a minor leak when we did the hydraulic tests).

Away from the boiler we have drilled the fixing holes in the new ash pan top flange. Six of these will need to be slotted before the ash pan is trial fitted later this week. Further progress has been made with the seemingly endless job of painting the coupled wheels and frames (only the top coat on the RH driving and trailing coupled wheels and a few bits of detail to do now) the tender front repaint is progressing after completion of a platework repair to the bulkhead, the injector flanges have been prepared for reassembling the injector pipe work and a start has been made on making the new gaskets we will need for the boiler and back head fittings.

Working parties this week will be on Tuesday afternoon/evening, Wednesday, Thursday, Friday and Saturday. The aim this week is to trial fit the ash pan, finish the boiler work so that it can be lifted upright and steam tested next week, finish painting the RH coupled wheels, refit the coupling and con rods and to carry on with the reassembly prep (making gaskets, annealing pipework etc). The boiler cladding sheets are also due to be shot blasted by a contractor this week. We will need to get a coat of primer on to these as soon as they have been shot blasted.

A pretty good week on the K1 at Carnforth last week. 3 of us there on Tuesday and Wednesday and 5 each day on Thursday and Saturday.

The priority for the week was to get the boiler boxed up and hydraulic tested. This was achieved and witnessed by our insurance company and John Graham (as independent examiner).

Other work included continuing with painting the frames and tender front, refitting the mechanical lubricator linkage, the back valve covers and combination levers and continuing with the refurbishment of the ashpan. Other than drilling the fixing holes in the new top flange the ash pan is now ready for trial trial fitting.

In addition to their involvement in the hydraulic, West Coast have carried out repairs to some of the cladding sheets this week. This was work that I had hoped that we would undertake but, unfortunately we just don't have the time.

Now that the hydraulic has been successfully completed the boiler will be turned on to it's side (scheduled for Wednesday this week week). This will enable the ash pan to be trial fitted and give easier access to the header, for preparation prior to to refitting the elements, and for replacement of a number of roof stay nuts.

While we had a good week last week we are still well behind schedule.

Three of us each day for Wednesday, Thursday and Saturday last week.

Work included removing the regulator, partially boxing the boiler up and progressing painting of the loco wheels, frames (LH just about completed) and tender front.

In addition the ash pan refurbishment is now almost to the point where it can be trial fitted (just a bit of tidying up and drilling the holes in the new flange plates).

Working parties this week at Carnforth will be on Tuesday, Wednesday, Thursday and Saturday. The first priority will be finishing the boxing up so that we can get some water in the boiler. As usual the company car should be available if required.

We are currently about two and a half weeks behind our "worst case" programme so we will certainly be spending more of the Groups money to pay West Coast to do work we could do ourselves. To keep this to a minimum please come and join us.

Reasonable progress on the K1's at Carnforth last week given the poor turn out for the week day working parties. 2 of us on Wednesday, 2 on Thursday but one ill so effectively only 1, 2 on Friday but 8 on Saturday.

As we arrived on Wednesday, West Coast had just reunited the leading wheel set with the frames. This meant that we could complete the refitting by replacing the hornstays and springs inc all securing. Other work included stripping down, cleaning and lapping in both safety valves ready for insurance co inspection, cleaning all mud hole doors and door openings ready for inspection, cleaning and tapping where necessary all washout plug holes, removing the dome cover (so that the regulator can be removed and the 'J' pipe blanked off ahead of the hydraulic test) applying the first coat of gloss to the driving and trailing coupled wheels on the loco's LHS, more cleaning between the frames, trial fitting the back head cladding following the repair work already carried out and to identify further improvement/repair work, painting of various brackets, further preparation and priming of the tender front and further preparation of the RHS of the frames.

The refurbishment of the ash pan progressed to a point where the door linkage could be trial fitted and the operation of the doors satisfactorily tested.

West Coast completed fitting the new tubes early in the week and are now well on with expanding. They also had all of the patch screws for the top mud hole doors doubling plate repair in place by the end of the week. The tubing and repair work should be completed this week.

Owing to a severe back log of urgent work at home there will only be working parties on 3 days this week, Wednesday, Thursday and Saturday. Our boiler insurance inspector is coming to examine the boiler on Thursday, following which we should be able to box the boiler up for our initial hydraulic test. It is also crucial that we progress the painting of the frames which should ideally be completed before we refit the side rods and motion. A good turn out on all days would therefore be very much appreciated.

Slow but steady progress on the K1 at Carnforth last week. Only 1 in attendance on Tuesday and 3 for Wednesday, Thursday and Saturday.

We managed to finish preparing the tube plates for fitting the small tubes and following John Graham's final pre tubing exam on Thursday, West Coast started fitting the new tubes on Friday. I had hoped that we could do much of the retubing work but I am having to leave this job entirely to West Coast owing to our poor mid week attendances.

We also managed to get the second coat of gloss on to LH side of the frames and part of the RH but unfortunately some of this will need to be done again as the paint went curiously lumpy towards the end of the job. Progress was however made with preparing the back half of the RH frames and the vac tank from between the frames has been glossed along with its brackets.

The new cones for the drivers side injector have now been fitted and further progress has been made with the ash pan. The ash pan job, done almost exclusively by Steve Gibson, is now nearing completion.

In addition to starting the retubing, West Coast are currently completing the repairs around the top mud hole doors.

Away from Carnforth Neil Smedley has completed the refurbishment of the front cab windows - they look great. Just hope we can get the rest of the engine to the same standard. Refurbishment of the graduable steam brake valve and diaphragm case has also been completed.

This week there will be working parties on Wednesday, Thursday, Friday and Saturday. We are currently behind programme. It is not too late to pull it back without paying others to do work we can do ourselves provided our mid week attendances improve.

Not the best 4 days on the K1's at Carnforth last week despite there being 11 of us there on Saturday (only 3 of us on Wednesday, Thursday and Sunday though).

Whilst we did not achieve everything as planned, we still managed to gap the RH piston packings (the LH being done a couple of weeks ago) shim and refit both cross heads, refit both sets of piston packings, clean the cab area and refit the repainted vacuum tank, carry out further cleaning between the frames, de-scale the and prime the brackets for the vacuum tank from between the frames, dress/prep the leading coupled axle hornstay bolts for refitting, progress the ash pan refurbishment, progress the preparation of both tube plates for fitting the new small tubes, apply the first coat of gloss to the LH side of the frames and RH as far back as the driving wheel set and continue preparing the RH driving and trailing coupled wheels and adjacent frames for repainting.

The plan had been to get the second and final coat of gloss on to the frames but as the temperature hardly got above freezing this was not possible. We also ran out of time to finish preparing the tube plates - this now has to be done in the next few days as fitting the small tubes must start this coming week.

The weld repairs to the boiler have now been NDT'd and found to be free from defect. The flues and steam pipes have also been thickness tested. While the flue s are fine the steam pipes are too thin for further service and will therefore be replaced (this has been budgeted for).

West Coast have now finished caulking the new stays and loose running plate rivets.

Progress on the various bits at Hopetown has been reported elsewhere so I will not repeat it here.

Steady progress on the K1's at Carnforth last week. 2 of us on Wednesday, 4 on Thursday, 3 on Friday and 5 on Saturday.

Again our main effort was around on with painting the frames but we also reassembled the axleboxes following completion of the re-metaling and machining by West Coast and continued with refurbishing the ash pan. Repainting the two vacuum tanks also progressed, the tank out of the cab is now completed and ready for refitting but the other one (from between the frames) is only in primer at present.

We also made new shims for the cross heads and removed the remaining rivets which were to be replaced on the frames - the new rivets have now been fitted by West Coast. There are half a dozen running plate rivets still to caulk (should be done on Monday) following which there should be nothing to stop us from completing painting the frames.

On the boiler we have made a good start on preparing the tube plates for fitting the new small tubes, West Coast have completed caulking the new stays on the outer wrapper/back head and have made a start on the inner box. The coaded welder completed the weld repairs on Saturday so I will be arranging to get the welds none destructive tested as soon as possible.

Away from Carnforth Steve Gibson refurbished the ash pan centre hopper door bracket/bearings and a start was made on painting the mech lub drive linkage.

This week there will be working parties on Wednesday, Thursday, Saturday and Sunday. The main aims for the week are to have the painting finished to the loco frames, at least as far back as the driving wheel set (this will enable the leading wheel set to be refitted next week) to shim the cross heads and to finish preparing the tube plates for the new tubes.

4 satisfactory days on the K1 last week. 3 of us there on Wednesday, Thursday and Saturday and 4 on Sunday.

Most of our time was spent on preparing/painting the frames and the two vacuum tanks removed last week plus further progress with the ash pan and cleaning between the frames. We also finished needle gunning the LH cylinder, gapped the LH piston packings and removed most of the rivets that are to be replaced from the top stretcher on the LH side. We will remove the spring hanger bracket rivets that are to be replaced this week.

West Coast have now completed the re-metaling and machining work to the leading coupled axleboxes one of them was "blued in" yesterday. The other one is likely to be done this week (if it hasn't been done today). The leading wheelset will therefore be ready to go back in very shortly but it will have to wait until the loose rivets in the leading wheel set area of the frames have been replaced (should be this week) and the frames have been painted.

On the boiler, West Coast started caulking the new stay heads over (until the compressor broke down) the 14 patch screws replacing the wasted door plate rivets have been fitted and the weld repairs to the throat plate bosses have been completed by the coaded welder. The remaining weld repairs should be done this week.

The new boiler tubes arrived today and while they will not start going in for a week or so there is plenty of preparation work to be getting on with.

We worked 4 days at Carnforth last week, with 10 of us there on Sunday! On the wheels/frames we progressed with the painting of the LH side of the frames, put a second cost of gloss on the leading coupled wheel set, removed the RH back valve cover to improve access to the frames for painting, removed the split pins from the brake hanger brackets to improve access for cleaning and painting, needle gunned the LH cylinder and removed both vacuum reservoir tanks for cleaning, examination and painting (one of them is now in undercoat).

Further progress was made with the refurbishment of the ash pan which has now been turned over so that we can access the hoppers and doors. The front of the tender has been needle gunned in readiness for repair and painting and on the boiler the foundation ring has been cleared of debris, including the removal of the old stays.

Ian Story called in to Carnforth on Thursday and dropped of the refurbished mechanical lubricator drive linkage (many thanks Ian). The linkage is now at Hopetown for repainting.

West Coast completed fitting the 69 new stays yesterday and 14 wasted steel rivets on the door plate/lower sides lap have been removed and tapped for fitting of replacement patch screws.

Away from Carnforth a replacement steam valve/pilot valve has been fitted to the graduable steam brake and at Hopetown further cleaning has been carried out to the valves and the painting of the sand pipes has progressed.
