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.43: August 2016

Hi folks,

Welcome to LYNformation 43, as the pace of assembly quickens and the final parts are being delivered...

1. Frame assembly (1)

Much of the final preparatory work on the frames was completed in late July. The main aspects of this work was checking that the all-important basic geometry of the locomotive was correct. This involved trial fitting the saddle, cylinders, driving wheel sets and coupling rods.
     
Then we had to make sure that they all went round as designed! This is one of the major jobs left in the construction phase and really is the heart of the locomotive. It is far easier doing this with the frame upside down, as the major components can be gently dropped into position without putting too much stress on the locomotive. It also exposes any snagging or misalignment of any of the many individual components that have been assembled. I am delighted to say that during this process hardly any issues were experienced, and the wheels went round. The coupling rods did just 'kiss' a frame stretcher but this close encounter was soon corrected with a neat application of the gas axe and angle grinder. Sorted! The images show the major components trial fitted whilst upside down.
   

2. Frame assembly (2)

Spot the difference!
   

3. Alan Keef Limited Heroes!

4. Frame Assembly (3)

Now the frame is the right way round and has been fully painted. (The buffer beam is not the final red but shows the basic idea!) It is more or less in the correct position for the next stage which is to final fit the cylinders and saddle. There is a still one frame stretcher to fit that has to go in after the saddle goes in, but that is already and just need welding.
 

5. Saddle

Having been trial fitted successfully, the final preparations are taking place to ease it between the frames and bolt it in permanently. One smallish error was found on the saddle which is being corrected, and it should all be in place around 5th August.
   

6. Copper Jointing gaskets

The copper wire that acts as the main joint between the saddle frame manifold and cylinders have been bought and are in the process of being fitted. This will allow the cylinders to be finally attached to the frames during week commencing 8th of August.
 

7. Driving Wheel sets

They are now fully painted and ready to fit. They are being kept under dust covers for the present but will be fitted under the frames within the next two weeks.
 

8. Pony Truck Wheel Assemblies

They are also now fully painted and ready to fit. There are a handful of parts that need to be delivered from South Africa before they can be fully assembled but these are due to dock on the 12th August and should all be at AKL by Friday 19th August
 

9. All Other Parts

The hope is that ALL of the final parts still awaiting to be delivered will be with AKL on or before the 19th August. This will allow the brake stand, brake gear, suspension and rear pony truck assembly to be completed. It is hoped that all of these major sub-assemblies will be installed ready for the AKL open day on Saturday 17th September.

10. Cladding

Attention is now turning to get the cladding on order. We will need the cylinder cladding ordered first but in terms of cost, the boiler cladding will be the most expensive. Both will be difficult to fit but with Solidworks, the basic sheet metal can be cut pretty accurately. More news of this subject next month.

11. Lead

I have some great news on our collection of lead. One of our members who previously worked in the x-ray industry has been working hard on our behalf and has single-handedly got promises of over 200 kilos of the stuff! Added to what others have collected, we are about 3/4 of the way to reaching our 400 kilo target. Please keep scouring the shed and pestering your builder for any old lead and bring it along to the open day or to Woody Bay.

12. Paint

As mentioned in LYNformation 42, the colour scheme has been agreed. The green paint swatch was passed over to the paint manufacturer, who has provided the finished article for us to approve. I think it looks brilliant but I will shortly be showing it to our paint consultant, Steve Phillips, to make the final judgment.

13. Finally, the Maker's Plate

Alan Keef would like us to use his standard maker's plate. It would be number 92 with the date of 2016 (when the frame was laid down). The 762 Board need to make a decision on this, how many we have, and where they should be fitted. This will be decided in the coming weeks but here is an image of a similar plate:
 

That is quite enough for now!

Thanks for your continuing support.

Peter
