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.14: March 2014


1. Pattern Making

Our volunteer member Brian Lloyd has been busy on the first (and largest) pattern that we need. It is the dummy cylinder cover top casting. I am pleased to show you his pattern as it is coming along. He has also completed the core box and they just need painting and sealing now. Then they will go to the foundry for casting. Thanks, Brian.

2. Chimney

The final piece for the chimney has been delivered. This is the complicated two radius plate that fits on top of the smokebox. It has been made by Israel Newton and has been delivered to Alan Keef’s works. Next month, we will put the whole chimney assembly together and so we should have a nice photograph to post!

3. Axles and Axle Boxes. We are making progress on the driving wheelsets, the wheel castings have been primed and had the bores checked for fit with the new axles. The axle steel should arrive next week. We will do the rough machining, and then sub-contract the finish grinding.

The axlebox castings have been ordered and are due early in March, other than the grease galleries, which are fairly simple to machine.

4. Bearings

We are really pleased to say that we have taken delivery of many of the SKF bearings that we need. I took a photograph of the 47 bearings we have bought so far, thanks to the generosity of all members who have contributed to our recent “Bearings, Bolts and Bars” appeal. A huge thank you to all concerned for so generously sponsoring these items. As you can see, they are very impressive. Believe it or not, there is 87 kilos worth of complex metal there! We will still need to buy some more, but this is a good start.

Incidentally, the appeal has so far raised over £2,300. A great effort and a big thank you. The appeal is still open, so please give as generously as you can.

5. Lubrication

We are now considering the plumbing, and one of the more simple layouts is that for Lubrication. As the locomotive is being built with modern roller bearings (and other types), the need for oil lubrication is much reduced.

To show everyone what is required, I have added the lubrication schematic diagram and the bill of materials. In essence, we just have three parts to buy.

Last month, we decided that we would purchase them now, as the mechanical lubricator has a 12-week lead time, and so for this month, we have one of the lubrication parts as our ’Component of the Month’. In fact, we have two opportunities for you to buy an important and visible part of the locomotive, in the shape of two Adams lubricators. We need one for each side, and we are looking for £175 each.

6. Regulator

Down at Highbridge, Andy Bennett has completed fitting the regulator, and very smooth it is too. I had my first ‘go’ with it, and great fun it was. Andy just has the dome to fit (he has all of the material, including the gasket pre-cut). By the time you read this, the dome will be on and fitted. The final thing to make is a small adaptor to mate the dome with the safety valves. This will also be completed shortly and trial fitting of the previously purchased safety valves will take place in early March.

7. Header

Another huge milestone has been the successful fitting of the superheater header. This complex fabrication has caused Andy to scratch his head on a few occasions, but in the end, it fitted perfectly first time. Well done, Andy.

This is now semi-permanently fixed, and only requires the superheater elements themselves to be fitted.

8. Superheater Elements

These are now being made and here is a photograph with the ball ends attached to the bends. The returns need to be welded on the other end, then fitted onto the header. I would expect these to be completed by the end of March. There was a slight issue with the dividers that keep the elements apart, but this was quickly resolved.


9. Valve and Motion

Good progress is being made to find companies to make various parts. Ideally, I am trying to get local North Devon firms to make parts for free or just material costs. I have been reasonably successful and I will write a fuller report next month, but one of the first tangible bits completed for nothing has been the lifting links. I am collecting them on 13th March from John Guest Limited who are based in West Drayton and who’s web site you can now see on the corporate sponsors page. Thanks to them, we have two beautiful quite big parts of the motion made. I have also commissioned some smaller parts that the 762 Club is paying for.

10. Coal Bunker

I am very pleased to say that the coal bunker is nearly finished and will be on display at the L&B Spring Gala, Woody Bay, on 10th and 11th May. This has been 100% sponsored and is being made locally. Once completed, this firm will go on to make the side tanks during the summer. This fantastically generous gift cannot yet be publically acknowledged, but we are very grateful. It will be great to display the bunker AND driving wheelsets in May.

I think March will be a busy month for the Club!

More soon, Peter Best
