All is revealed as Brian sets to work on creating the GWR Shirtbutton Livery on the tanks of 5542. The loco will carry this 'less common' livery for the first period of its new boiler certificate and we hope it will add some variety the the GWR loco 'scene'. Its first public airing is due for the SDR Jubilee weekend Gala.

Following several days of serious 'rubbing down' the big task of re spraying the side tanks and bunker got underway in the early hours of this morning with the aim of completing the task in one day, which was duly completed. There was however still some 'tradition' painting relying on a brush and paint tin ably completed by Mike. All is now coming together and the remaining hardware should be delivered during the coming week allowing the much awaited 'self propulsion' to get underway. The SDR Jubilee Gala has 5542 rostered to work a regular 2 coach 'Branch Line' working during the event which runs for all 4 days of the Bank Holiday weekend. A real taste of how things used to be. The evening timetable sees us working until almost midnight on one of the days. Why not pay a visit?
A good finish begins with the preparation. There are no shortcuts.

Work today continued on the endless checklist of nuts and bolts that need to be tightened and suitably split pinned, along with the 'tweeking' of rod runs so that the maze of pipes and linkages do not foul each other in every possible combination of operation. To that end we have now completed the main vacuum pipework, drain cock linkage and front sandbox controls. Other work completed this week and seen in action is the new ashpan control arrangement.
As followers will be aware we recently had the tanks and bunker shot blasted and resprayed by an outside contractor. Unfortunately we were very disappointed with the final results especially when compared with the finish that has been achieved on the other paintwork that has been completed 'in situ'. So we have taken the decision to repaint the tanks and bunker and you will see the arduous rubbing down process which Tony has almost completed single handed for us over 2 days, under strict instructions from the painter himself. Final completion of that process is expected within the next 10 days, hopefully to coincide with the completion of the new piston assembly.
These two unplanned expenses have not helped our overall finances, so if you've been impressed with the timescale of the overhaul process and our 'blow by blow 'account of what's involved a quick visit to the 'Donations' page might just help us a little.

Following on from yesterday's Steam Test success, attention today returned to the outstanding work to complete the re assembly of various components along with the preparation and spraying of the remaining boiler cladding. The drain cock and front sanding controls were being slightly modified and fitted to the cab whilst various small cladding parts and the fronts steps received the painters best efforts. The cab condensing pipe work was also given a once over prior to refitting next week.

6 keen workers braved the monsoons to get to Buckfastleigh today where the remaining work ahead of next Friday's final steam test is gradually being ticked off. Most of the work centered around the cab where painters and engineers worked in perfect harmony, so 10 years must have mellowed the demeanour of some, of us as on the last overhaul painters and engineers worked on different days!
Inside of the cab roof was cleaned and a coat of Cream Gloss paint was administered, whilst the main supports for the wooden floorboards were also being produced and fitted. The last major backhead component, the gauge frame has been fitted during the last week along with completion the new vacuum pipework. Front right side running plate was refitted and various parts of cylinder cladding were cleaned ready for refitting. The outside of the cab front along with the top of the firebox also received the paint sprayers attention yesterday. Final work is also underway on the ashpan operating mechanism, and full details of our new design and operation will all be revealed in the fullness of time, but we believe will be the most user friendly of any operational locomotive, GWSR firemen get your turns booked now, you won't be disappointed.

First the main news this week is that the penultimate insurance inspection of the overhaul was passed on Thursday 19th. This was the 'Final Internal' inspection and the date of the 'Final Steam Test' has been set for Friday 4th May. By this date all boiler and associated steam fittings need to be in place, fully operative and in steam tight condition.
Today's work saw action at both ends of the boiler with further progress in the smokebox on the less spectacular but all important parts including spark arrestor brackets. However very importantly the Blast pipe is now 'in situ' as is the Smokebox door. More of the backhead fittings are finding their way back to the their respective 'homes' with just the Gauge Frames being the major missing component now. Re-routing of the Vacuum pipework has been required to allow the Auto operating gear to be located in a more practical and accessible location and in (we think) an altogether better arrangement than the original GWR/BR design. Other routine work included front footplate refitting following valve installation and preparing the newly turned wooden tank lid stops for fitting.

Today was a day of good steady progress as the team continues the process of reassembling the engine ready for the forthcoming final boiler tests. It is good to already be putting back all those components we removed as recently as last October.
Today's home made cake at tea time was lemon drizzle cake.
The all-important steam fountain and the right hand injector were reinstalled and much of the associated pipework was annealed by heating and quenching and a start made on reconnecting the tanks to the boiler. Now that the cab is back in situ the many bolts that fasten it and the tanks to the frames are now secure.

Work today centered around manufacture of new copper pipework for the Steam brake/ejector exhaust in the smokebox, and the pictures show the fruits of a long and 'thankless' day last Saturday packing a copper pipe with ever more grains of sand which supports the pipe during bending. This allows a smooth internal surface rather than a rippled one, allowing steam to pass unhindered. Other work involved fitting of the front damper door on the ashpan, fully bolting down the tanks and some surface preparation work on the cab fittings prior to refitting next week.

Work continued today on fitting the remaining insulation and cladding to the firebox along with further work on the backhead cladding sheet ahead of delivery of bunker and tanks from the paint shop due early next week. Evidence of this week's work on smokebox component reassembly with regulator, superheater header, superheater elements and main steam pipes all in place. Other work centred around painting cladding and preparation of copper pipe for production of new smokebox ejector exhaust pipes.
Work has progressed on cladding the boiler backhead.

The boiler today passed its hydraulic test with flying colours, and work will now progress towards the steam test as soon as possible. This is likely to be within 7-10 days. Watch out for that news, and visit our sales and display stand at Williton during the Spring Gala for the very latest updates. Pictures show 260 psi reached on the boiler test and the Superheater Header and elements being inspected by the SDR works manager (Rob LeChevalier) and Boiler inspector (Ian McKenn)

Despite no formal working party today lots has been happening during the past week and I will take the opportunity to catch up on recent goings on that may have been missed in other updates.
The main news of the week is that following the blanking of the boiler, the preliminary hydraulic test was underway on Friday and the pressure was raised to about 165 psi (over half the final test pressure) and no undue problems have shown as yet. The full test is due by midweek this coming week and the boiler should start steam test 'warming' by the end of the week following refitting the grate and ashpan.
Meanwhile the tanks and bunker have been away receiving the attention of the painters and currently sport a new 'mottled' grey/green livery. New corners were fitted to the bunker prior to dispatch as, when we closely inspected what remained of the old ones there was surprisingly little.
We will have a 5542/Auto 169 stand at Williton during weekends of the WSR Spring Steam Gala. Please look in for a chat and further news updates

Work today was mainly involved with final boiler tubing work and painting. Most of the tubes have now been expanded and where necessary 'Beaded Over'.
This process is probably unfamiliar to those not intimately involved in boiler work or footplate staff. It is a process whereby all the tubes at the firebox end are rounded over to reduce the risk of the ends burning and thereby reducing the life of the tube. It also increases the area of steel tube in contact with the copper firebox increasing heat dissipation and also reducing the possible burning of the steel. Some are also beaded at the smokebox end mainly to make access to the fittings easier to manage. Fittings surfaces have also received attention and new studs fitted to the smokebox faces.
Hydraulic test blanking plates were also retrieved and sorted ready for the imminent test. Most of the boiler now sports a coat of silver paint. Other work continues on the frames, including 'ride height' checking and adjustments. The tank and bunker repaint work is also progressing off site and hopefully some pictures of this work will be available soon.

10 workers active again today and we are now nearing completion of tube and superheater flue fitting. All small tubes are in place and have had first expansion work completed along with 'beading over' in the firebox end. The Superheater flues were placed into their positions but these need to screwed into the firebox and expanded at the smokebox end. Due to the wall thickness this is a much more physically demanding process. The outside of the firebox was wire brushed and the paint gang began the paint process.
We are hoping to be in a position to hydraulic test the boiler within the next 7 days . Out of frames steam test should then follow soon after with the boiler returning to the frames due soon after, all subject to sucessful test of course.
Ashpan modification work continues and is on target for completion ready for refitting when required. Further work was also undertaken on auto gear fitting along with routine adjustments work on the front and rear pony trucks.

10 workers today and we are at last well into the retubing process which got underway in earnest late last week. Well over half the 196 tubes are now resting in place in the boiler following preparation swaging to both ends using the recently installed machinery which is both simple and efficient in its process. Tubes are reduced by 2-3 mm at the firebox end by forcing a collar arrangement over the tube end and expanded by a similar amount at the smokebox end by forcing a solid former into the tube end by about 300mm.
Other work concentrated on producing a Crinolin 'cage' arrangement for the top half of the parallel boiler section to help support the cladding in that area and avoid the risk of damage when it is walked on during cleaning and tank filling operations. Other work underway is the modification of the ashpan and mounting arrangements to the bottom of the boiler. The new design will allow for easier disposal of the locomotive at end of daily service, and also further reduce the risk of dropping hot ash during normal operation.
Work completed during recent days included fitting of the new stainless steel delivery trays in the boiler, dispatch of the tanks and bunker for sand blasting prior to re spray. This work should be completed within about 3 weeks.
Further work on the new Auto Gear assembly has also been progressed along with the mid week paint gang work on and around the frames .Our 'new' Stones Generator has also been delivered .

Today saw 8 active workers at Buckfastleigh and the current situation finds us with all the driving wheels now checked and refitted, with no work required on any. We are replacing the axle box lubrication pads all round.
The pony wheelsets are yet to complete although they are prepared for inspection and are not expected to reveal any problems.
Last week saw riveting work undertaken in various areas and eventually we have taken the opportunity to replace a few more than originally planned (approx 60 in total) because some of the remaining ex B.R. (possibly GWR) ones that we first took out were definitely showing more signs of wear and tear than we expected which then warranted further investigation and replacement. This probably was responsible for some 'chattering' at the point where cab and tanks met. Many of the removed components are receiving general cleaning to allow for easier reassembly when required.
The replacement piston and valve components are all understood to be progressing via outside contractors to schedule.
Some small modifications to the bunker have also been completed

Boiler Work News.
A range of new administrative requirements during major boiler overhauls has delayed progress a little since the New Year. This means that we now find ourselves playing 'catchup' and are currently 2-3 weeks behind our original schedule. (those approaching a '10 year' overhaul take note) However this does not mean that we have made no progress in this area and apart from receiving the formal go ahead from our boiler inspector this for all remaining work up to the hydraulic test, today has seen much stay work activity. The new copper stay work on the front plate has been completed today, along with much of the steel stay work. Final measurements of boiler barrel plate work has revealed just a few small areas that we will build up for 'good measure' with the tapered section actually, despite our reservations pre stripping, being in very good condition, especially as it is now at least 50 years old.
The pictures below will show large areas of white 'crack test' paint which has shown no plate work/stay area cracking and just a very small section of cracked weld which can be very easily rectified. The internal corners of the firebox are also in fine fettle.

Happy New Year to all our 'visitors'
A new Year 'catch up' with progress at Buckfastleigh reveals that despite the recent break for the festive season progress continues both in the boiler shop and on the routine work on the frames and wheels. The replacement plate on the firebox outer wrapper is progressing well and we shall soon be starting the retubing work. Needlegunning work on the boiler barrel continues during our visits with attention now on the boiler barrel. Having now inverted the boiler to allow the riveting and replacement stay work to progress, descaling of the underside is much easier. I'm pleased that we only have a relatively small boiler!
In the main workshop full use is being made of the wheel drop facility to check out the axleboxes and journals as it is now 5 years since the retyring work was done. We are pleased to report that having completed 2 of the 3 driving wheelsets no undue wear or damage has been found and the modifications to axlebox lubrication made during restoration have proven 100% sucessful. Whilst the centre drivers are out of the frames we shall be replacing a few rivets that have worn a little loose over the years on the frame stretchers. This work should be completed this week so the last driving wheelset can be checked out and the frames made ready to receive the boiler once again.
We are pleased that work continues on schedule and on budget at present, and having recently secured an 'underwriter' we will be progressing the repaint work on tanks and bunker in the next few weeks. Let the livery debate begin!

Work on the boiler has concentrated on reconstruction of the smokebox with handrails and internal bracket etc being fitted. The endless needlegunning work continues when we have volunteer labour available with Saturdays work concentrating on the top sections. The top mudhole doors have been completed with the doors trial fitted. The 'Bottle Ends' for superheater flues have now been manufactured and 200 small tubes have been delivered as part of a 'lot' to cover the SDR's needs for the rest of the winter. Some of the injector pipework has been removed for minor modification and the Chimney, blower ring and petticoat pipe assembly have been separated ready for checking and refitting.
Bearings for the Auto Gear have arrived so work can continue in that area as and when time allows. The next major work will involve dropping the wheelsets to check that all is well, but we are not expecting to need any major work in that area.

Monday 28th November Day +55 (about a third of the way through the project)
Boiler work has continued with the new plate on the firebox front now prepared and welded in place ready for staying and riveting to take place. The top mudhole doors have received attention to return them to good condition and work on the new smokebox has continued with internal brackets fitted and the door also trial fitted, it has also been offered to the boiler to confirm correct fitting and alignment. We are well on target to commence tube replacement before Christmas. The overhaul of boiler fittings continues steadily as and when time allows, and all backhead faces have now been cleaned and refurbished as necessary.
On the frames some of the riveting has now been taking place along with sandbox refurbishment.

Work is now really moving on apace. The boring work is now completed on cylinders and valves with a complete set of valves and pistons now being manufactured. Work on the boiler itself is now also in full swing with the area of plate for replacement now removed and preparation work on the new piece underway . Work on overhaul of fittings continues, along with Auto gear work.
Sunday 13th November Day +40
Yesterdays' work continued the needlegunning preparation for the main boiler work to begin.
The boiler internal trays and associated brackets have been removed to make access a little easier. An informal visit from the boiler inspector on Thursday last continues to reassure us that there will only be limited major work and also confirmed the crown stays to be in good condition requiring no major work, with just some nuts being replaced.
Design and preparation of the rodding runs for the front end Auto gear continue along with work on cladding components to allow easier fitting during reassembly. Work on the cylinder rebore is now complete with attention to the valves being undertaken later this week.

Yesterday's update visit to the S.D.R Engineering found our boiler having received its first serious attentions of the engineering staff by way of boiler plate thickness measurement concentrating on the backhead platework and crack testing of B.R. welding on the boiler barrel joints. All of the above resulted in our continued good fortune and no excessive wear or cracked welds found to date. The foundation ring is also very good with no grooving found.
The main steam pipe has been removed and one of the more undernourished members of the workshop staff has managed to squeeze between the longitudinal stays to get a close up view of the only other major unknown factor at present namely the Crown Stays, but even these look in reasonable condition at first sight. We now keanly await the boiler inspector's visit later this week for confirmation of the boiler work program.
Other work has included stud removal on Superheater header and Fountain.

6 workers today shared their attentions between needle gunning the boiler and planning the fitting of the front end Auto gear.
Attention on the boiler concentrated on cleaning up the vulnerable areas so that those required to confirm what work is going to be required can get the clearest possible indication of the current condition. We are optimistic that we will have a full picture of required work in 7-10 days time. The new smokebox door was also available for inspection

Thursday 27th October Day +23
A visit to Buckfastleigh today revealed the boiler now removed from the frames with all tubes and flues removed, along with all boiler fittings and associated studs. At first look the unclad boiler shows no obvious unforeseen problems, and the work that will be required is generally no worse than we had planned for. Final confirmation and a work list will be drawn up once the boiler has had the attentions of the ‘needle gun team’ who will start work on Saturday(29th). Overhaul of the boiler fittings is now also underway with several already completed. New superheater element ends have been delivered to replace those fitted 10 years ago with the intention of them completing 2/3 years at best. We are pleased to report that 95% of the boiler cladding is fit for further service and with the luxury of being able to work with the boiler out of the frames the few replacement and modified parts will be much easier to manufacture than first time around. The lubrication regime we instigated mid way through the last 10 years has also paid dividends with valves and regulator now receiving ‘just the right’ amount of lubrication and are therefore in excellent condition. Who says you can’t teach steam loco drivers new tricks!
The valve and piston liners will receive some routine attention during the next few weeks. We will take the opportunity of replacing a few loose rivets in some of the frame stretchers whilst the boiler is absent along with replacing some bolts that were used due to restricted access issues when the frame repair was completed 5 years ago. Finally, a quick 'Thank -you' to Mr. Bridger for the kind donation.
