I dont find these tenders particularly ugly. They are a bit like GW Castle tenders to my eye

 

if you google Fowler high sided tenders and look at them with say a 4F or a 4-4-0 they (in my eye) look terrible. They also dont look good with a jub. but for some reason, maybe its the parallel lines of a pat, they look really smart together (again only in my eyes).

 

That is correct, the water capacity was the same and the coal capacity was larger than the'standard' tender. For main line use we need extra water and less coal, which is what we will have on the re-designed body.

Engineering Update - March 2014
Locomotive Frame Assembly
Work continues at Tyseley Locomotive Works on preparing to fit the axleboxes into the main frame. All the Horn Guides are now ground and the frame assembly has been measured to determine how much to machine from each axlebox to get the axle centre in the correct position. The Axleboxes themselves have had all the remaining oil holes and fixing holes for the brasses machined in. The brasses are ready to be pressed in over the next couple of days. The journals will them be machined to the size of the axle and the bronze wearing faces machined to the sizes determined from the frame assy. Then the frame assembly will be lifted onto the wheelsets and axleboxes.

Before that can happen, the wheelsets need to have the balance weights filled with lead. Unfortunately we are still waiting for delivery of this from the supplier, despite several reports that it is to hand. At present we expect the completed wheeled chassis to return to Llangollen by the end of April, but all depends on the delivery of the lead.
Inside Cylinder Casting
The machining of the Inside Cylinder Casting has been completed at Harco Engineering; Brierley Hill is due to be delivered to Llangollen on 2nd April, ready for fitment into the frame assembly on its return from Tyseley.

The Outside Motion Brackets and Smokebox Base Side castings have also been finished machined and will move to Llangollen with the cylinder casting.

Outside Cylinder Castings
The pattern for the first Outside Cylinder Casting was completed in mid March and is due to be delivered to the foundry in early April. We expected this to be cast by the end of the month.



The second pattern will be started and taken to a stage where modification, if required after the first has been cast, will be possible. It is planned at present for the second cylinder to be cast in May.
Discussions are ongoing for the machining of these castings.
Bogie
Work continues on several fronts on the components for the bogie.
Boro Foundry have finished the machining of the Bogie Centre Casting and the part has now been delivered to Tyseley.
The Bogie Centre Slide Casting is waiting for the final machining operations to be completed. This is the final casting to be machined for the bogie assembly; all the Horn Guides and Side Control Spring Mounts have been completed for a while.

It is anticipated that all the parts being delivered to Tyseley by the end of April. Assembly of the bogie is to start in the second half of the year.
Boiler
Detailed drawings for the copper Inner Firebox flanged plate have been delivered to LNWR,Creweto enable a start to be made on the forming blocks for these plates. Next parts requiring drawings are the Foundation Ring and Inner Firebox Wrapper.
An order is about to be placed with Tyseley Locomotive Works for the Outer Firebox Throatplate and the Doorplates. These steel plates are probably the most complex formed plates on the boiler. Delivery to LNWR Heritage, Crewe is expected around the end of the year.
Tender
The design for the new tender tank with revised coal space and increased water capacity is progressing.
Consultancy
3D CAD models for replacement cylinder patterns have been completed for our colleagues at the Strathspey Railway. Some checking is required as the cylinders are of an early design and the only drawings available are of a later type. One of the original cylinders has been moved to Harco Engineering, who have been awarded the contract to machine the new cylinders, for some detailed measurements to be made before the patterns will be made.

Kind regards Gavin

 

Please excuse my ignorance, but what are these "original" cylinders and where does the Strathspey Railway come in?

 

The Black 5 at Strathspey requires new cylinders, as the originals have suffered corrosion and cracking after 80 years on the loco. The owning group contacted us to ask how we produced the cylinders for the Patriot, which has ended up with me providing the cad data and project managing the supply of machined castings.

This may have been answered elsewhere so apologies (and equally this may not be the place for it) but does the advent of 3D printing technology present opportunity for pattern making?

Well quite a good day as days go in my opinion.

Kevin West visited Coupe foundry today and took this fantastic image. Please click on the web address on my signature and see latest news for a report from Kevin.

 

Thats a lovely looking casting. Is the cylinder design an exact copy of the original or have any enhancements been made ?

 

Only difference from the original design is the material. We have used SG Iron which is much stronger that normal Cast Iron. But as SG does not have the same lubrication properties as normal Cast Iron, we are fitting Cast Iron liners in the main bore. The diameter of the cylinder body has been increased to allow for the liner. The valve bores have liners anyway.

I recently went outside, this evening, into the warm summer air (for a change!) of an English twilight on 6 June 2014 to raise a glass and drink a toast to all those who, 70 years ago today, changed the course of history that we might live in peace and freedom, despite what our personal views of what real peace and real freedom mean. How good it will be, quite soon, to see our "Patriot" in steam and to rededicate a locomotive to be the standard bearer of Remembrance. Ladies and Gentlemen, your support please, on this day more than most.

 

For those of you visiting Tyseley open day on the 5/6th July you'll be happy to hear that 4/5551 will be there to view.

 

Latest update on progress on the Patriot.

The locomotive was finally wheeled at Tyseley Locomotive Works at the end of June. The locomotive remained at Tyseley to be on display at the open weekend on 5th & 6th July.


Work continues at LNWR Crewe on production of the formed plates for the Inner firebox.

The Unknown Warrior now has a full set of 3 cylinders following the casting of the second Outside Cylinder at Coupes Castings, Preston in early July.

The locomotive is now due to moved from Tyseley to Llangollen in the next few days to be on display for the projects members day on 19th July.

Thanks once again Kev for more good news, she must be still on target for delivery ? unfortunately I am away for members day, but will look forward to seeing the other members posts and hopefully photo's/videos. Will she be returning to Llan. with the middle cylinder fitted ?

Andy

 

I think im right in saying that the middle cylinder has/is being removed at Tyseley and moved to Llan without and the new one will then be fitted after members day but before the Great Dorset steam fair.

For those of you not on facebook/checked out the website 4/5551 has been invited to attend the GDSF this year. All costs are covered by the GDSF before we get into the same debate from a few pages back about Warley. So it doesnt cost us anything, it just gets us publicity and helps fund raise. And unlike Warley where many people has heard about us as its a railway exhibition the GDSF is more general public. So we get to talk to lots of people who dont know about our project. And just over the hill is the Royal Signals museum where they actually have one of the original nameplates. It would be nice to do something with them.

 

The Unknown Warrior arrived back in Llangollen late afternoon yesterday and was unloaded this morning. Now safely back in the shed after being cleaned and polished.

The inside cylinder was removed at Tyseley prior to the move and the replacement will be fitted at Llangollen in the next few weeks.

To expand on Gavin's comments, The Unknown Warrior's next public outing will be to The Great Dorset Steam Fair, Tarrant Hinton, Blandford Forum, Dorset, from 27th to 31st August.
A feature this year is a WW1 Centenary Commemoration Display.

At present we believe The Unknown Warrior will be displayed adjacent to this feature display.

 

Anything that gets 5551 into the public eye cant be a bad thing.
