Ahead of our next major engineering update a couple of pictures to illustrate examples of ongoing work behind the scenes at Tyseley.

Very much a work in progress shot of the recently manufactured lamp irons and cylinder block cover hinges. The castings were derived from 3D wax patterns; costly and time consuming to manufacture however their accuracy results in less time and money spent on machining.

GER 789’s chimney was cast by South Lincs Foundry some yours ago; recently removed from storage, cleaned and painted pending installation.
In October 2020 most businesses involved with the UK’s preserved railways and associated enterprises were in the midst of Covids’ grip; the result being that many commercial organisations were faced with an uncertain future due to their incomes being either severely reduced or eliminated. Skilled staff were furloughed in the hope that the pandemic would reduce in severity and that businesses would eventually return to something of the level attained prior to lockdown. Organisations of a modest size such as The Holden F5 Steam Locomotive Trust were no exception to the rule of income downturn as our opportunities to publicly fundraise were effectively removed as a consequence of lockdown.
As we entered September 2020 the Trust’s income had stagnated to a certain extent until we received a letter from a solicitor confirming the pending arrival of a very generous legacy left to the Trust by a gentleman whom sadly passed away awhile back. “Ron” had been a member of the Trust since the early days and prior to then had been a member and supporter of the Ongar Railway Preservation Society (ORPS) that I had instigated in 1992. Thanks to Ron’s very generous gift to The Holden F5 Steam Locomotive Trust Tyseley Steam Locomotive Works were in the position to proceed with the construction of GER 789’s frames.
Within a few days our CME Elliot Powick was having detailed talks with Alistair Meanley, CME of Tyseley Steam Locomotive Works resulting in a Schedule of Works being agreed to. GER 789’s castings were removed from secure storage and prepared for assembly. GER 789’s frames were relocated to Tyseley’s Workshop, cleaned then primed ahead of construction.
Tyseley’s renowned steam engineers under the leadership of CME Alistair Meanley together with regular input from Holden’s CME Elliot Powick made phenomenal progress to such an extent that by Christmas 2020 the frames were rapidly approaching the hot riveting phase.
The two images below clearly illustrate the amount of skilled engineering and progress that Tyseley under the leadership of Alistair Meanley and GER 789 CME Elliot Powick have achieved to date.
GER 789’s frames have been hot riveted together, the machined cylinders have been installed, the smokebox and footplate have been installed pending riveting plus four new buffers have been bolted to the frames. Design of the radial trucks and horn guides has been completed however we are waiting and hoping for the escalating price of steel to falter and ideally drop before proceeding with casting.
Behind the scenes ongoing meetings will formulate the next Works Schedule and an announcement will be made soon. Meanwhile our original CME Graham Rowland continues to research drawings as requested by CME Elliot Powick.
Quality assured engineering ensures that the build of GER 789 progresses unhindered therefore with an expert and experienced engineering team working on GER 789 the future is looking very positive and secure.

3D wax printed castings are more expensive to make but are an investment. With the accuracy achieved, final machining and fitting time actually make them cheaper than normal traditional patterns and sand casting. Elliot Powick, CME.

Progress with the spring gear continues apace with more components being completed and awaiting installation.

As mentioned in a recent news bulletin, Tyseley has manufactured four new buffers utilising components from two previously donated buffers. The above images have been cropped pending a further and more detailed engineering report to be published soon.
A rare glimpse of the area between the face of the cylinder block and the motion bracket. The four leading spring pillar guides ( including the two rear guides) have been aligned with a gauge bar and riveted to the frames.

The cylinder hood has been trial fitted whilst the smokebox front plate awaits riveting to the wrapper. Meanwhile the smokebox door, hinges and door dart have been overhauled and await reassembly.
The original smokebox has been dismantled and all parts serviced. The smokebox wrapper has been replaced with one of the correct thickness and delivered to Tyseley.

The smokebox front plate, hinges, dart and locking bars etc have been serviced pending reassembly.

Cylinder cover supplied by Graham Rowland Elliot Powick.
The cylinder hood has been delivered to Tyseley, has been machined, awaits hinges and fitting to the frames.
Various stops and brackets that support the cylinder cover have either been trial fitted to the frames or are under manufacture.

Fabrication of all four buffers is progressing with buffer beam mounts being affixed.
Buffers nearing completion. Elliot Powick.
Suspension.
Front suspension components have been temporarily bolted to the frames; more details and images to follow soon.
The build of GER 789 continues apace. Riveting of the frames has been completed ahead of the trial fitting of the smokebox and bunker.
As can be seen from the image above, the front buffer beam has had all rivets ground flush, has been primed and awaits the fitting of buffers. The rear buffer beam is at the same point of progress. The footplate has been positioned and awaits riveting to the frames.
The Trustees are delighted to announce that our original CME Graham Rowland has returned to assist our current CME Elliot Powick. Meanwhile Tyseley and Elliot Powick continue to further progress the build of GER 789 with axle boxes, crank axle and plain axles currently receiving priority attention.
Be sure to visit frequently to remain current with the build.
A minor engineering teaser prior to our next major engineering update.
Some years ago a Holden member kindly donated two complete buffers to the Trust. Upon recent inspection at Tyseley it was discovered that a few of the buffer components were damaged hence it was decided that the best way ahead was to have new and missing parts made. All four buffers are pending affixing to the buffer beams. We’ll let the picture tell the story!
Construction of GER 789’s frames approach completion. Elliot Powick.
Elliot Powick CME and Tyseley Steam Locomotive Works under the leadership of Alistair Meanly CME have further progressed the build of GER 789 as the frames near completion.
Work undertaken to date includes hot riveting of the front buffer beam to the stiffener and frames, installation of the cylinder block and motion bracket, hot riveting of the mid frame stretcher, diamond stay, rear buffer beam and associated bracketry.
The four tank supports have been riveted into place to be followed by the footplate supports.
