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 has expired too. The locomotive is being stripped down to assess the scope of repair and refurbishment work required to return it to service.



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.

We worked on the K1 for 4 days last week. We have continued with grinding and drilling stay heads, finished removing the external smokebox fittings and the RH expansion bracket, replaced the paint removed to facilitate last week's boiler NDT. The fracture in the chimney has been stitched and we have also measured up for the new firebox platework and quotes are currently being sought.

On the mechanical side, needle gunning of the cylinders has continued, two more cylinder relief valves have been cleaned and serviced and a start has been made on removing the injectors.

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

If anyone would like to paint any of the components requiring re-painting, either at home, Grosmont or Hopetown please let me know and will get it sorted.

We have worked on the K1 7 days since the last update. On the boiler we have now finished needle gunning the outer barrel, wrapper and back plate, two necked studs have been removed from the LH clack box pad and the remainder have been die nutted. The LH expansion bracket has been removed (mainly by Steve G in the pouring rain - what a star) and the nuts have been removed from the RH bracket. Further stay head removal and drilling has taken place and we have continued needle gunning the inside of the barrel. Most of the remaining exterior smokebox fittings have also been removed and two sheared crinoline mounting studs have been drilled out and the holes re-tapped.

On Friday gone the independant boiler NDT was undertaken, with a good few hours prep the day before. Only one problem we were not expecting so a pretty good result overall. The superheater header and steam pipes were thickness tested and found to be suitable for further service. Having said that the header will probably need significant work or replacement at the next overhaul. The suspected fracture in the 'J' pipe was also confirmed with a mag particle test.

On the mechanical side a good start has been made on needle gunning both cylinders with only a few nooks and crannies to finish off. They can then be Die Pen tested. Removal of the valve heads has been completed and they have been tittivated where needed. They can be refitted when the valve rods have been trued.

Many thanks to Angie Buxton, Steve Gibson, Mike Bloomfield, Frank Hryniewicz and Ashley Moor who have all worked on the K1 since the last report.

 

 

Tuesday 25th January 2022

Since the last update we have started needle gunning the inside of the barrel. Its a slow job but strangely rewarding. A start has also been made on removing the stays (grinding heads off at this stage) where the lower firebox sides are to be replaced and we have continued with descaling and painting the outer barrel and the areas of the firebox wrapper to be retained.

On the mechanical side we have all but finished cleaning the piston valve heads and the crossheads and slidebars have been removed, cleaned and the crossheads die pen tested (no defects detected). New slidebars are required and it is hoped that an order for these will be placed very soon. The crossheads are now at M.Machine in Darlington where they will be refurbished including a new LH top slipper (the RH was replaced in 2019). New little end pins are also required. As they have to be manufactured to match the crossheads M.Machine will also carry out this work under contract.

Many thanks to Angie Buxton, Lizzy Fielding, JP Venus, Robbie Ellis, Steve Gibson, Rolly Bingham and Mike Bloomfield who have all worked on the K1 at Carnforth since the last update and to Neal Woods for his tireless and priceless work to date in progressing the various instructions, specifications, procedures and quotations in respect of the numerous repairs/replacements required as part of the overhaul.
