CAD plotting of  holes to frame plate

Stafford Road Design has further progressed CAD plotting of the frames. Discussions with TM Specialist Engineers of Kingswood, West Midlands have commenced regarding CNC drilling and milling.

A meeting with Bob Meanley, CME of Tyseley and Stafford Road Design is scheduled for early January 2017. Due to a dearth of workshop time, Tyseley is expected to undertake assembly of the frames during the latter part of 2017. Upon completion, the frames will be transported to another location to facilitate wheeling.   Further details will be published soon.

October Engineering Report

Behind the scenes, engineering has been progressing steadily.

To ensure that what we manufacture is fit for purpose a considerable amount of time and CAD work has gone into design and test fitting so as to avoid unnecessary and expensive mistakes.

Following research of our drawings, the Trust has decided that, unfortunately, we can’t go for the cheaper original option of running Joy valve gear as we’d originally hoped but instead, we will have to run with the later Stephensons valve gear. As a consequence, we will have to manufacture all of the additional eccentrics, straps and rods which we’d hoped to have avoided.

All the drawings for the additional frame stretchers, angles and buffer beam brackets are finished and Tyseley Locomotive Works will be adding the manufacturing costs to the build quote. In addition, the drawings for the bolts and rivets required to fix the frames together have been put out for quotation for CNC manufacture to keep the costs down to a bare minimum.

The original hornguides were of an angled construction, this was to allow for adjustment during service to take up any slack in the assembly.

It was decided at an early design stage that all was really required for 25mph running were parallel hornguides hence a new design has been generated instead. These are going for quotation this week and hopefully casting in early November.

Following a visit to Tyseley on Oct. 28th a plan of action has been drawn up to start the process of frame erection. At the moment Tyseley is coming to the conclusion of several large projects and once they are completed and out of the works our job can start in earnest. In the mean time Tyseley will make a start on the additional bracketry as previously described and hopefully, the frames can move indoors for the first time for assessment and a start to be made on the hundreds of holes needed to create the assembled frames. I’ll be visiting Tyseley again on Nov’ 13th to catalogue exactly what’s there and make sure everything is in place to make a start late this year, early 2017 (current projects depending).

Also a start has been made on quotations for the wheelsets. This is a huge undertaking as a crank axle is required which will need massive expenditure from the trust so once we have quotations in from Ian Rileys and SDR Engineering we can see exactly what’s needed financially.

We also have a price for the driving wheel pattern, this will be a traditional pattern and cost in the region of about £3000.00

image005

Coupled to this we already have the pattern for the leading and trailing wheels so along with three plain axles we have a good starting point for getting the loco on its wheels as soon as money provides.

Whilst we looking at patterns we realised we hadn’t got one for the heart of the loco, the nameplate. A CAD model has been completed and a local manufacturing company has offered to machine the pattern FOC. Once this has been done its off to get two castings done so we can display them on our stand for all to see and once the loco is finished they’ll take pride of place on the loco itself. If someone would like to sponsor the brass castings then please feel free to contact us.

Engineering News August 2016

 

The Holden F5 Locomotive Trust is making preparations to erect the frames and create the ‘rolling chassis’ of its Great Eastern Railway 2-4-2T No. 789, with the completed cylinder castings delivered to Tyseley Locomotive Works, and design work well in hand on the rest of the ‘bottom half’.
The CAD (Computer Aided Design) patterns for the driving wheels have now been finished and will be sent out for quotations in the coming weeks, along with those for the axles and axleboxes. The modified  axlebox horn guides and their infill plates have also been designed.
The last remaining large part to be produced for the frames will be the motion bracket – but because the drawings for the Stephenson valve gear have not survived, a new design will have to be produced from scratch and modelled to ensure that it fits together.
Project Manager Elliott Powick of Stafford Road Design Ltd said: “Once this is finalised Tyseley can put together a plan and costing for the frame erection, so the kit of parts that the group already have can be turned into something more than a large Meccano set.”
The frame plates were cut in 2012 and the cylinders cast in 2014, while the Trust has also produced the ‘star stay’ (a star-shaped frame stretcher beneath the cab), the smokebox and door, chimney, bunker and bufferbeams.
For more details or to make a donation (payable to Holden F5 Steam Locomotive Trust) write to 49 Beech Avenue, Halstead, Essex CO9 2TT
The group’s sales stand will be in attendance at The North Norfolk Railway on 3rd September 2016 and the Festival of British Railway Modelling, held at Doncaster Exhibition Centre on February 11/12 2017. For additional information please click on “Meet the team”

Wrenford Thatcher GER 789 Commission.

Wrenford Thatcher is one of Britain’s most successful railway artists, currently creating stunning artworks depicting accurate records in railway history.

Wrenford Thatcher was born in 1944 in Hertford and led a happy childhood on the footplate, around both grandfathers who were engine drivers,  working on the former GER, LNER and finally for BR. From the war years onwards, Wrenford lived in Hatfield and spent his spare time at the line side sketching trains.

He attended St Alban’s County Grammar School where he excelled in sciences and the arts, winning a number of awards for his artworks. He attended London University and studied Mathematics and Physics where he achieved a PhD in Physics. Wrenford became a teacher of Electronics and Astronomy at various Universities, entailing extensive travelling in America and Europe.

Throughout these journeys, paintings flowed whenever time permitted. Two subjects dominated his interest; the stunning scenery of the west coast of Scotland and most importantly, steam locomotive and railway scenes, no doubt stemming from his grandfathers.

His railway paintings are always met with great enthusiasm and has perfected a style that encompasses precision, accuracy and attention to detail, tackling the complexity of perspective. Each painting faithfully represents an historical account of a golden era, reflecting Wrenford’s unquestionable passion for railway engineering.

GER 789 at Stratford station low level.

Although it is generally not recommended that paintings are hung in direct sunlight Wrenford Thatcher’s paintings will withstand it more than most because he uses natural pigments such as raw umber, yellow ochre etc which will not fade. Only red buffer beams are at risk as the use of arsenic red is no longer permitted! The painting is spectacular in sunlight-the shaft of light on the locomotive makes the blue livery stand out from the grey surroundings. This is a technique which Wrenford Thatcher has copied deliberately from the old grand masters such as Rembrant through to Canaletto who knew all about this. The technique was lost by the impressionists and has never resurfaced.

A limited edition of signed and numbered, high-quality prints of Wrenford Thatcher’s GER 789 will be available for purchase in the near future. For more information please contact info@holdenf5.co.uk.
