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.10: November 2013
1. Grant Received
I am really pleased to say that we have been awarded a Grant of £3,000 from the Tanner Trust, and a cheque for this amount has been received.
The Tanner Trust is a small charity set up in memory of Mr. Basil Tanner, the founder of heating radiator firm, Copperad. This is normally a closed charity, i.e. it does not accept unsolicited appeals, but in this case, the trustees were persuaded about the merits of our project.
The Tanner Trust likes to support projects in the Devon/Cornwall region, and saw the educational and environmental benefits of the “LYN” project.
Is there anyone out there within the 762 family who would have some time to assist the Directors prepare other applications to similar charities? Please contact Jon or Peter if you can help.
2. Drawings Release
I am very pleased to say that a BIG batch of drawings has been released by Mike Nelson and Ian Gaylor. This batch covers the Valve Gear, and 67 drawings have been lodged in the Central Library - in the section “Released for Manufacture”.
This is great news as it gives us some nice meaty (but expensive) parts to look to have manufactured soon. The next batch will be the motion drawings.
3. Dome Splitting and regulator assembly
I am also pleased to report that the amended drawings for the recently agreed splitting of the dome have been prepared, and the design team and boiler maker are have agreed how this phase will proceed. The dome will be split just above the barrel and two flanges will be made. One of the flanges will be welded onto the lower part of the dome, whilst the second will be welded to the top part of the dome. This allows for simple assembly and fitting of the regulator and better access for maintenance and adjustment. Work on this will begin soon and it all should be finished by Christmas.
4. Sponsoring Firms
I am very pleased that we have had a good response to our limited request to have parts made for us. I have recently visited two firms in Barnstaple and had very encouraging meetings. The outcome is as follows:
- a) Whiddon Valley Engineering
This is quite a large precision engineering company based in Barnstaple. They specialise on work for the F1 (motor racing) industry, aerospace and military contracts. I met with the owner, Darren Smith, who bought the business in 2004 after a career with Aston Martin and Jordan. Darren is sympathetic to the idea of making some parts for us, but until he sees the drawings, has not committed to anything yet. However, he thinks they can help us and I will be sending him drawings for both the slide bar sub-assembly and the cross-head sub-assembly for him to consider. Both are large, significant parts for the locomotive, and of course, there are two of each!
- b) ND Precision Products
Another Barnstaple precision engineering firm who’s MD is Nick Squire. ND Precision have amongst their staff some existing L&B supporters. Again, they have not made any firm commitment, but have also asked for sub-assembly drawings to view. In their case, the machinery is not quite so large as WVE, and their speciality is more in tool making. Nevertheless, they wish to help and have viewed the drawings I had, in particular, the Expansion Link sub-assembly (Drawing A3-LYN-050). Again, there are two required, and they are another key (and expensive) component. I am pretty optimistic that they will agree to make them, but we will need to provide material.
- c) West End Precision
This is a Bideford-based firm, specialising in the volume manufacturing of precision components. Their offer is somewhat different. They are prepared to allow any 762 Club-approved machinist to visit theirt premises and use WEP equipment, and they would also provide raw material, if we know of any local machinist who would be able to take up this offer. Any takers?
The success of this first limited appeal directly to precision engineering firms has been so successful, that The 762 Club will now widen the range and number with the hope that we can encourage others to help us make parts. Hopefully more good news in future months.
5. Driving Wheels
As previously reported, all four of the driving wheels have been cast. The most recent good news is that they have now been machined and are practically ready to be delivered, expected at Alan Keef’s in mid-November. This is another major milestone in the renaissance OF “LYN”.
Revised drawings have been prepared and sent to our preferred contractor, Robert Frost of Norwich. We are also pursuing other possible routes, with the aim of making a firm decision within the next few weeks.
7. Pony Truck Wheels
These have also been cast and delivered to Alan Keef’s for safe storage until the drawings have been completed for the pony truck assembly.
8. Safety Valve
These two items - sponsored by John Yeo and Mariette Pringle - have been delivered and are safe with Andy Bennett. A reducer is needed to fit between the boiler and the safety valve, but these are proprietary items.
9. Brake System
The design team has agreed how the brake system will operate, and we are in the process of drawing the system and have placed an order. The first item is November’s “Component of the Month”.
