The 762 Club - LYNformation Bulletins
Aware that much development has been going on in the background, but little has been seen in public, and also that the pace of development is gradually increasing, the 762 Club introduced this on-line update feature in early 2013. This page, updated around once a month, will provide brief news snippets, images and general "Lynformation" on our progress. Please come back regularly for the latest updates.

LYNformation Bulletin No.38: March 2016
Welcome to LYNformation 38.
A relatively straight forward month for LYN with not much obviously going on
at Alan Keef's yard, but plenty happening around the country and
internationally in the cause of getting LYN build.
1. Front Weight Box
This static component - A2-LYN-085 - will balance the engine weight-wise, and allow sufficient down force on the front drivers and pony truck.
It could only be designed and drawn once all of the calculations had been made and all individual components theoretically weighed. Now that has been done, it was deemed that more weight would be needed on the front of the engine, so assembly A2-LYN-085 was needed.
Regular viewers to the website will recognise that this assembly formed part of a recent CoM (Component of the Month). I am pleased to report that the assembly was sponsored, an order place with a local fabricator, and ten days later, hey presto! A finished weight box! It is quite a lump empty but when it is filled with lead, it will weight 421 kilos!
So how is the lead collecting going on? I have been offered some by Alan Keef (they had a new roof last year) and have had a few other offers, but we really do need a bit of imagination of how we can collect enough to melt down and fill the box.
3. Hand Brake Stand
We have now purchased all of the material to make all of the components needed to finish this assembly. Although we have not ordered the machining of the last six items, this will be done during March. Two of the bought-in parts are the brake stand hand wheel, and handle. These were sponsored via January's CoM and have been bought and delivered to me. I will shortly be taking these parts over to Ross for assembly.
4. Suspension components, A3-LYN-998 suspension bracket
We are very lucky to be able to call upon the experience and knowledge of Phil Girdleston. Phil was a former FR man who moved to South Africa to work on the 2' Gauge locomotives running on the South African narrow gauge system. Phil was instrumental in making numerous improvements to the NGG 16's Beyer Garratt's that ran commercially up till the mid 1990's. Phil has remained in South Africa and owns an engineering business. He supplies many items to the FR/WHR and is an old friend of Ian Gaylor. Phil is helping me find and overhaul several parts for my Beyer Garratt 130 and we have asked him to make several components for the suspension arrangement. I attach a photograph of the components coming together to make the rear equalising beam hanger welding assembly. We need two of these (handed), and they will come across with other parts during the summer.
5. Brake Gear Components, Brake shaft profiles
I am very pleased to say that all of the material to make the components have now been ordered and paid for. The biggest lumps were the RQT 701 for the brake shafts, brake hangers and cross members. I attach two photographs of the rough water jet cut profiles all palletised up waiting to go off to be machined by our good friends Whitelands Engineering in Bideford. They hope to have them done by the end of April.
6. Rear Control Linkage assembly
Last month, I showed you an assembly drawing of the complex rear control linkage assembly, and much progress has been made to bring this vital assembly to fruition. We have added another key part to this bundle of parts - the pony truck cam plate A2-LYN -1022.
This part is associated with the linkage assembly and is made from tool grade steel. It was convenient to bundle this with the other parts that Longshore are doing for us. I am pleased to say that we have agreed a beneficial price for all of the parts with Dylan Simpson and he has given us the material dimensions he requires.
These have now been ordered and will be shipped down to Delabole in the next week or two for Longshore to start machining all of the components. In the meantime, there are 12 SKF bearings needed. These have been ordered from a SKF distributor in China! Even allowing for freight, they offer a considerable saving on locally purchased bearings.
Hopefully, the whole assembly will be ready by early May.
7. Sand Dome
Our resident pattern maker extraordinaire, Brian Lloyd has been busy again! This time, Brian has taken on (single-handed) the construction of the two sand domes. The first thing he needed to do was to make this substantial pattern for the complex curved shape for the sand dome top. The domes will be made in 3 parts, with the top curved section being quite complex. The pattern is now finished and has been taken to the foundry for casting.
Thanks Brian, it looks fantastic!
8. Main Spring assemblies
We purchased the springs some time ago and now we need to make the main spring mounting assemblies - A3-LYN-070. These will be needed quite soon and we have asked a contractor in the North East to look to quote for it. Hopefully, we will be able to place an order for these within the next week or two.
That is quite enough for now!
Thanks for your continued support, and remember to look at the new list of components to sponsor!
Thanks as always.
