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.46: November 2016

Hi Folks,

Another very busy month with plenty of activity, so without further ado, here is the news:

1. Inside Motion

All of the inside motion as been trial fitted and where necessary, minor easements have been made. It all went together quite well and with no serious issues. The final clamps for the eccentrics have been made and fitted. It will need to come apart once more for painting (where necessary) but it will stay 'up' until the outside motion and reach rod are fitted, so that the whole motion can be tested together. This should be done by Mid-December.
     
       

2. Couplings

Not strictly urgent yet, but we have had a good 'go' at sorting the couplings out. We intend to use as close as possible Calthorpe Couplings as per the original LYN. These were made from Southern Railway drawings in our possession but sadly as drawn, they would not fit! The design team have made the necessary alterations, and the procurement process began. The L&B had castings made a few years ago, and the 762 Club bought a set. These castings now need both machining and modifying. These parts will be delivered to Nigel Heath next week and should be back with us by the end of the month.

The photographs show components recently delivered back to us, ready for assembly.

   

3. Coupling Tensioner Assembly

At the rear coupling, there is a tensioning arrangement. This whole sub-assembly has been made for us by our friends at the Welsh Highland Railway.

The great news here is that they have decided to gift the whole sub-assembly to us free of charge. Thank you so much, Paul Lewin, Tony Williams, and Jon Whalley for this incredibly generous gift.

 

4. Coupling Chopper

. This part fits on the front coupling assembly and again has been provided free of charge by the boys and girls at the FR/WHR. Thank you!
   

5. Boiler and Cylinder Cladding

Excitingly, the boiler cladding is finished! It is a bit of a gamble having it made now but at least it's done. This section of the cladding was incredibly generously sponsored by a member. The really difficult bit was the rolled backhead and our contractor, de Havilland Engineering of Stonehouse have done a great job with it. I could not get a photograph of it as it was upside down, but believe me, it feels and looks brilliant.
     

6. Cylinder Cladding

They are also well on with the cylinder cladding, the photographs show the rear cylinder cover cladding completed. In all, we have issued five separate orders for the cladding. Three have been completed, with the balance scheduled for completion by the end of November.

De Havilland will also etch prime all of their work, saving time at Alan Keef's.

   

7. Rear Equalising Beams

You will know from previous LYNformations that when the boiler was first trial fitted, it did not go in completely. The firebox fouled the rear equalising beams (as well as another issue). A design solution was agreed and this involved taking the beams down and having a sliver of metal machined out. This has now been completed and, with a few other minor corrections, will all be finished by 11th November. The whole rear suspension can then be put back together ready for the second trial fitting.
 

8. Boiler: Second Trial Fit

A date has been set for the second trial fit. (We hope that there will only need to be two, plus the final fit).

This is scheduled for the end of November, and will be a very critical day if we are to meet our 12th May deadline.

On this day, we will fit the bunker, the footplate, the boiler, the cab and both side tanks. It will look like a real engine (if it all goes together).

The purpose of the trial is to:

  1. make sure all parts fit without any snags.
  2. allow us to design, draw and have made, the main steam manifold.
  3. test whether the side tank mounting holes line up.
  4. make up and drill the smokebox holes to fix to the saddle.
  5. test the new boiler holding down brackets.
Unfortunately, We cannot allow members to attend this day, as it will be quite chaotic with large bits of metal flying around, but we will feature it fully in the next LYNformation.

9. Raffle

Please do not forget to buy your raffle tickets. Just see the PRESS RELEASE on our web site, or contact me or Jon Pain.

That's about all for now, bar saying that the next seven weeks to Christmas will decide if our dream of unveiling LYN next May can be achieved. It will be a close run thing, even if there are no new hold ups. I will be pressing AKL hard!

Thanks,

Peter
