A log of activities associated with the K1 62005.

The K1 returned early to Carnforth from 2021 Jacobite duties with worn wheel flanges.  The tyres were at minimum size - which would not allow another reprofiling on the wheel tathe. The 10 year boiler ticket expired soon afterwards. The locomotive is being stripped down to assess the scope of repair and refurbishment work required to return it to service.



K1 update 12th July 2022

Print

We have worked on the K1 at Carnforth for 15 days since I wrote the last report (a few less since it was distributed).

On the boiler/firebox, the preparations for removing the outer wrapper sides are all but complete with only the seal welds to break through before the boiler can be inverted. Special thanks are most certainly due to Steve Gibson who burned round about 500 of the 600 stays on this particular job.

In addition to the above, the back plate and throat plate/foundation ring corner patch screws have been removed  - those to the back plate came out without too much drama but 8 out of the 10 to the throat plate had to be drilled out. Bolts have also been fitted to temporarily replace some of the throat plate/barrel rivets.

The new regulator stuffing box pad/boss stud has been fitted, completing the replacement, where needed of all back plate pad studs and further preparation has been carried out to remove the roof stays that are to be replaced.

A start has been made on refurbishing the top and back plate mud hole doors. We will leave the throat plate and lower side doors until the holes have been cut into the new platework.

The snifting valve has been serviced, including machining the bottom (header side) face and replacing the associated studs and the slacker pipe valve has been serviced and painted. A replacement (very good second hand) atomiser isolating valve has been provided by anonymous doner as the old one was worn out. The only difference between the new and old is the pitch of the thread for the outlet union nut. We had a suitable nut in stock so the outlet pipe has now been re-ended with the replacement nut.

On the mechanical side the loco brake weigh shaft and brackets have been needle gunned and the shaft primed. The bushes in the brackets are to be replaced and the ends of the shaft built up and machined. The L.H. trailing horn lubrication pipes and steam chest pressure gauge pipework has been removed for partial replacement. The new RH piston valve nuts have been manufactured by Mike Hirst under contract and fitted by us. We have also had a couple more frame cleaning sessions.

Work on the cab roof continues - the new platework has been drilled for fastenings, where needed and primed. The refurbished the whistle linkage cross shaft has been satisfactorily trial fitted and painted, along with the rest of the whistle linkage.

Many thanks to Angie Buxton, Lizzy Fielding, Steve Gibson, Mike Bloomfield and Frank Hryniewicz who have all worked on the loco since the last update.

Away from Carnforth the new slidebars are complete (and will be collected from Dormor Engineering this Wednesday) and new LH cylinder and brake weigh shaft fastening bolts have been manufactured by Hawk Fasteners.

 

K1 update 9th June 2022

Print

We have worked on the K1 at Carnforth for 9 days since the last report. While you do not normally get a weather report with my updates it was ridiculously and uncomfortably hot for most of the time we worked at Carnforth late May/early June so my thanks to those taking their time to work on the K1 is particularly sincere on this occasion.

On the boiler/firebox, all of the throat plate/barrel rivets have now been removed and burning around the stay heads to the LH outer wrapper has been completed. Three quarters of the RH has also been done. The method for this has changed as the chisel bit for gun used to knock the heads off broke and replacements are no longer available of that particular type. After trying burning round a few full heads, which took much longer than just going round the stays with the heads removed, we tried cutting the heads down with a cutting disc to reduce the size then burning. This worked well and was just as quick but much less physically demanding than using the windy gun.

More needle-gunning of the barrel interior has also been done - this particular job is now very close to completion. The regulator rod has now been removed (we had previously only moved it enough to allow us to get in and out of the boiler) which has allowed the removal of two "necked" studs from the regulator stuffing box pad/boss. One of these has been replaced from stock and the other ordered.

On the mechanical side the LH injector has been removed  as has the loco brake weigh shaft (which is heavier than it looks) and the loco steam brake piston has been cleaned and passed to contractor Mike Hirst who will manufacture and fit a new little end pin after reaming the holes true. The brake piston will also require new rings. We have also had a couple of communal frame cleaning sessions - which everyone seems to love!

Work on the cab roof continues. The areas too corroded to save have been replaced - we got West Coast's John Massingham (Mass) to do most of the welding (see photo) as he is much better and quicker at it than me. Other than that rust removal/treatment and priming of the outer face of the roof is almost complete and the whistle linkage cross shaft (normally fitted to the underside of the cab roof) has been refurbished by Mike Hirst under contract and is ready for trial fitting.

K1 update 24th May 2022

Print

We have worked on the K1 for 5 days since the last report.

On the boiler/firebox the removal of the throat plate/barrel rivets is almost completed - only 5 more to do. Preparation for the removal of the outer wrapper platework continues with the burning of the platework around the side stays (see attached photo of Steve undertaking this task). No more progress has been made on the seamingly never ending job of needle-gunning the interior of the barrel (not safe to do while we are inside the barrel burning and drilling rivets out) but all of the palm stays have now been needle-gunned.

On the mechanical side the tender brake tables, hangers and all associated pins have been removed and cleaned ahead of inspection and NDT, the split pins have been removed from the tender hornstays and the nuts slackened ahead of dropping the wheelsets out. The loco brake weigh shaft is now also ready to be removed.

Work on the cab roof also continues - more corroded and consequently more to replace than anticipated but nothing too drastic (or expensive).

Away from Carnforth the new slidebars are nearing completion at Dormer Engineering and Elm Tree Fabrications have manufactured a new cladding case for loco steam brake cylinder.

K1 update 10th May 2022

Print

We have worked on the K1 for 6 days since the last report.

On the boiler/firebox all of the stubborn foundation ring rivets have now been removed and removal of the throat plate/barrel rivets continues. A start has also been made on removing the side stay heads to the steel platework that is to be replaced and on burning out the outer wrapper/throatplate rivets. Further progress has also been made on removing the roof stays that are to be replaced. More needle-gunning has been carried out to the interior of the barrel - this very time consuming job is now nearing completion. In addition 5 of the 9 palm stays have been needle gunned in preparation for inspection and NDT.

On the mechanical side the intermediate draw gear and tender brake linkage have been removed and cleaned ahead of inspection and NDT.

Work on the cab roof also continues - largely in the form of rust removal and priming. This now tends to be a late afternoon/early evening job for Angie and me but if anyone who likes that sort of thing would like to take is on as a project I would be delighted to hear from you.

Many thanks to Angie Buxton, Lizzy Fielding, Steve Gibson, Robby Ellis and Rolly Bingham who have all worked on the loco since the last update.

 

K1 update 27th April 2022

Print

Following the unplanned break in our activities at Carnforth owing to covid we got back to 'normal' last week with working parties over 4 days. Angie and I had also done a couple of days over the Easter weekend.

Since the last report the coach workshop has had a good tidy and the white board rearranged. Some minor joinery repairs have also been carried out to one of the guards doors.

On the boiler/firebox some of the stubborn foundation ring rivets have been removed (still 17 to do though) all throat plate/barrel rivets have had their heads burnt off and all but 16 punched out. The 16 that are left will need drilling out. More needle-gunning has also been carried out to the interior of the barrel.

Unfortunately, while the new copper plate for the firebox sides has been ordered there is a much longer lead time on delivery than originally anticipated. This means that we have re-ordered some of the work (to minimise the delay to the completion of the boiler overhaul) by bringing the roof stay replacement forward. A start has therefore been made on removing the stays that are to be replaced. Despite the delay in getting the copper plate the intention is still to complete the whole overhaul by April next year.

On the mechanical side all of the LH cylinder bolts have now been checked. A total of 18 are to be replaced - new oversize bolts will be ordered shortly. They will be turned down to size when their holes have been reamed true.

In addition to the above the centre section of the cab roof has been removed so that we can replace the heavily corroded beading bar around the centre section appeture and deal with corrosion to the cab roof platework in the same area. The whistle operating rods and cross shaft have also been removed for renovation.

Many thanks to Angie Buxton, Lizzy Fielding, Steve Gibson, Mike Bloomfield, Frank Hryniewicz and Rolly Bingham who have all worked on the loco since the last update.

 

 

K1 update 16th April

Print

Unfortunately there has been no further working parties on the K1 at Carnforth since my last update as Steve, Mike and I have all had covid and as of yesterday we were all still testing positive.

In the circumstances there will be no formal K1 working parties at Carnforth until next week although as it is a Bank Holiday tomorrow so there will be no one on site to contaminate, Angie and I are going over for a couple of days. If you also have covid and would like to join us then please let me know!

 

 

K1 update 5th April 2022

Print

We have worked on the K1 for 3 days since the last report.

Inside the firebox pilot holes have been drilled into the copper side of all throat plate stays and most of the foundation ring rivets where we had previously removed their heads, have been knocked out using Chris Beets "rivet buster". Many thanks to Chris for the loan of this. Just a few very stubborn rivets left to get.

Removal of all 9 palm stays has also been completed and more needle gunning of the barrel interior has been carried out (nearly there now).

On the frames more LH cylinder bolts have been checked and found to be ok and had new washers and nuts fitted. All sands pipe brackets have been removed and cleaned.

In addition to the above the condition of the tender spring hangers has been assessed and a decision made to renovate rather than replace. We will be seeking quotes for this work very shortly.

Many thanks to Angie Buxton, Lizzy Fielding, Steve Gibson, Mike Bloomfield, Rolly Bingham and Robbie Ellis who have all worked on the loco since the last update.

 

K1 update 29th March 2022

Print

We have worked on the K1 for 6 days since the last report.

Inside the firebox the heads have been burnt off most of the foundation ring rivets - these are now ready to be knocked out and the stay heads have been ground off the copper side of all throat plate stays.

A start has been made on removing the palm stays and more needle gunning of the barrel interior has been carried out (not much more to do now).

On the frames more LH cylinder bolts have been checked, most of which are satisfactory. The cylinder casting around the bolt holes is being needle gunned, die pen tested and painted as we go, and where the existing bolts are being retained, new washers and nuts are being fitted. The current count is 16 to be retained, 16 to replace with 10 left to check.

The loco steam brake piston has been removed (rings and gudgeon pin to replace) and a start has been made in removing the loco brake weigh shaft in order to rectify excessive play in the supporting bushes.

Many thanks to Angie Buxton, Steve Gibson, Mike Bloomfield, Frank Hryniewicz, Oli Williams, Andrew Jeffrey, Tom Dibbs and Rob Morgan who have all worked on the loco since the last update.

Away from Carnforth work on the new slide bars being undertaken under contract by Dormer Engineering has been delayed owing to a machine failure. Work should however restart later this week.

 

K1 update 15th March 2022

Print

We have worked on the K1 for 3 days since the last report.

Inside the firebox the drilling of pilot holes to all of the stays where the outer wrapper is to be removed but the copper retained has been completed and a start has been made removing the foundation ring rivets - most of the heads burnt off the LH side and a start made on the RH. More needle gunning of the inside of the barrel has also been carried out (still quite a lot to do though).

On the frames more LH cylinder bolts have been removed. While we had budgeted for replacing all of these this will not now be necessary. The inside of the frames behind the LH cylinder and associated frame stretcher have been cleaned and the loco steam brake cylinder cladding has been removed.

Many thanks to Angie Buxton, Lizzy Fielding, Steve Gibson, Mike Bloomfield and Rolly Bingham who have all worked on the loco since the last update.

We have worked on the K1 6 days since the last report.

The boiler has now been put onto a lowmac (see photo) which makes access a little easier. We have continued needle gunning the inside of the barrel and drilling side stays.

On the mechanical side the LH injector has been removed and cleaned, servicing the cylinder relief valves has been completed, both cylinder covers have been needle gunned and painted, the LH piston valve has been reassembled (we are having new nuts made for the RH valve so this will be reassembled later), the RH drain cocks have been serviced and we have started removing every other LH cylinder fastening bolt - the cylinder has been moving on the frames so all bolt holes are to be reamed and new bolts fitted.

Many thanks to Angie Buxton, Saskia van Schip, Lizzy Fielding, Steve Gibson, Mike Bloomfield, Frank Hryniewicz, Rolly Bingham and Robbie Ellis who have all worked on the loco since the last update.

Away from Carnforth work on the new slide bars (by Dormer Engineering) is due to start this week - thanks to Neal Woods for organising this.
