As you will see from the recent Newsletter (No. 6). many tasks, large and small, are being carried out to produce some of the thousands of components required to complete Lyn. At Alan Keef's on 25th February, these photos were taken showing some of the smaller components - this is the regulator gland:

Alan Keef Engineering, 30 August 2012

Alan Keef Engineering has recently completed work on these components for Lyn's internal regulator, including the regulator quadrant, main steam valve, linkage and bearings. These items have been despatched to Bennett Boilers to be fitted to the boiler.

Bennett Boilers, 10 May 2012 1/5

Five photographs taken on the 10th May 2012, by 762 Club Finance Director Jon Pain, at Bennett Boilers' works.

Solid progress is being made on the construction of the boiler. The principle boiler components have now been purchased and are on site, these include; boiler barrel, outer firebox wrapper and smokebox.

Work is currently focussed on the fabrication of the firebox, and we look forward to providing further updates over the coming weeks, along with views of the work in Progress at Alan Keef.

Casting Wheels - "Little and Large"

In April 2011, Lyn's first wheels were cast, at the Trefoil Steel Company in Tinsley, Sheffield.

Casting Wheels - ready for machining

These wheels were ordered to test the patterns. The remainder will be ordered shortly, and will include machining.

It will be noticed that the tyre is part of the casting and the wheel profile will be machined straight onto the casting.

In due course after wear and re-profiling, it is intended that steel tyres can be fitted for further service. This is in line with modern day methods, but a novelty in the world of steam preservation.

Casting Wheels - Sparks are flying

The design of the driving wheels is complete with the exception of final detailing of the balance weights which will be finalised once the motion design work has been dealt with. The patterns include sufficient material for the balancing to be completed by removing surplus material from the wheels.

Lyn's Nameplates

When Baldwin Locomotive works built the 2-4-2 for the Lynton & Barnstaple it was finished in Holly Green with nameplate painted on at the works. These certainly have the look of 19th century America about them. Clearly the Pilton staff thought likewise and before long the fitter had made up two new plates with steel backing and brass letters 1/8” thick sawn out of sheet and riveted on.

Those plates stayed on ‘Lyn’ until the fateful day in 1935 when she was unceremoniously cut up for scrap in the same sheds at Pilton where she had been lovingly (?) assembled 37 years before. One plate went into private hands and the other into the York Railway museum along with the nameplates from her fellow L&B sisters.

When we began the planning for the replacement ‘Lyn’ I was able to visit the NRM at York and given permission to climb up the wall and take dimensions and photographs of the nameplate. Whilst doing that, the brass rivets became very clear as they are a slightly different shade of brass (softer material for rivets) The corners of the frame were soft soldered with butt joints.

Some drawings were prepared, material obtained and a few new hacksaw blades. A while later and my riveting skills were brushed up and then the polishing began. The result is a pair of new nameplates of the correct size and construction which will no doubt receive plenty of Brasso over the coming years!

As a final point, the cabside photos of Lyn appear to show nameplates much thicker than the ¼” of the metalwork. The reason is that a backing piece of wood has been used, sandwiched between nameplate and steel cabside; I wonder why?

Jon Pain and Peter Miles going for a “cab ride” in the newly completed cab with the name plate and number plate for the finished locomotive. Note ‘Lyd’ in the background – imagine in two years time this cab could be assembled to the rest of the engine and ‘Lyn’ could be in the up platform.

Lyn at AWH, 2010 (1)

The completed wooden cab manufactured by AWH Joinery Ltd in Luton. The cab has been constructed to the designs & details of the original, in American Ash with hardwood windows and steel infill panels. Drawings were prepared using the original general arrangement drawings plus information culled from photographs taken at various times in the life of the original loco. Thanks also to Steve Philips for construction details and advice.

The metal roof covering will not be added until the cab is assembled on the locomotive, as will the sliding roof vent. Note the tongued & grooved timber roof boarding in place.

Lyn at AWH, 2010 (2)

Detail of the sliding windows with toughened safety glass fitted to the cab.

The hardwood windows are finished in Danish Oil - which will not crack, split or peel as varnish does. The majority of the cab will be finished in black and the inset steel sections green. The green will be a specialist paint in Maunsell Green by TR Williamson (as used on Birch Grove at the Bluebell Railway, lovely!). Inside the cab, the roof & walls are in dark stone and below waist level, black.

Other details will be added to the cab including ironmongery, bolts, driver & fireman’s seats, handrails, armrests, so that it will be as far as possible ready to lift onto Lyn when the rest is ready, and bolted down with the angle bracket fixtures.

Wheel Patterns on display at Woody Bay

Construction of Lyn is underway, and evidence of this was seen at the Lynton & Barnstaple Railway's Autumn Gala over the weekend of 26/27 September, 2009 - the completed patterns for both the driving and truck wheels are on display in the marquee.
