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.

Welcome to LYNformation 32.
Firstly, welcome to a really big bumper LYNformation, with lots of good progress to report for a change! So, without further ado, here goes!
This will be an opportunity for all members, sponsors, and the press, togwether with their guests, to witness the frames, wheel sets, and other items all together and just waiting for the final assembly.
By then, we will have everything bar the brakes, Ashpan and manifold. Exact details of the open day will be published nearer the time, but the times will be 9.30 to 14.00, and both Patrick Keef and I will be on hand to welcome you.
PLEASE NOTE: The date of this event has been changed. It is now on Saturday 28th November, not the 14th as previously stated. We hope you can make for what will be a great and unique event.
With the extra costs that have been needed to be spent on the frames, when we get to November, the coffers will have run dry and we will have no money to complete the assembly. An estimated £100,000 will be needed to allow Alan Keef to complete the locomotive, so a major new fund raising campaign will be launched at the open day to fund this gap.
Where do I start? Readers will know that last Autumn, we received a fantastic offer from Babcock's to provide all of the material, cut it, and assemble the whole frame package.
Subsequently, once they had seen the drawings, they told us that they did not have the 80mm thick plate in stock, and that we would have to buy it. (£3,200).
Sadly, in April, the old Managing Director who had made this offer retired, and the new team rowed back on their commitment. They still agreed to provide all of the material they could for free and to profile cut it all, but they would not assemble it.
Even this was a huge positive sponsorship deal for the 762 Club, but we knew that we would have to find about £10,000 for the assembly. In the event, what Babcock's presented to us was some way below what we expected in terms of scope and quality. Worst of all were the two large 80mm profiles that were poor and cannot be used. The only solution was to start again, and have them water-jet cut. This has now been done, but at a combined cost of £7,800. Also, Babcock's did not drill the plates that they cut, so we have had to mark off all of the profiles and to drill them, resulting in another £8,000 in costs.
Finally, we always knew that we would have to drill and machine the horns into which the axle-boxes will fit, as well as the very fine tolerance holes that fit the cylinders through the frames and into the saddle. The whole lot comes to about £30,000 extra, and will clean us out financially. The good news is that all of this has or will be finished by 14th November.
The main plates have been cut and were delivered to the machinist on 2nd September. They will then come back to AKL for the holes to the saddle to be drilled. All of the other profiles have been made or drilled, including the apron plate and the footplate. On or around the 21st September, the whole lot, together with the saddle will go off to Lowther's for assembly. They have promised a 6 week turnaround, so as long as we can deliver all of the plates to them by that date, we will have a finished frame to show off on 14th November. A rather horrible experience but we are nearly over it now.
Design and drawings took far longer than expected and the costs are much more than expected. Nevertheless, the 762 Club has ordered both pony trucks from AKL and work is well advanced on the first one.
Basically, the trucks have four main components: The Wheel sets and axle boxes. A3-LYN-064 The truck Chassis. A3-LYN-066 The Rocking suspension assembly. A3-LYN-068 The Spring Assembly. A3-LYN-071 And then finally the whole assembly. A3-LYN-053 Good work has been going on during August, and about 50% of the front pony truck is now complete illustrated by the following series of photographs.
The wheel sets are now finished bar assembly and once the axles are back from the machinists (due in about two weeks' time), then the axles can be pressed onto the wheels and assembly into the chassis can begin. See how many parts you can spot?
That is quite enough for now.
See you all on 28th November! (not the 14th as previously advertised!)
