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.20: September 2014
Just 15 months to go!
Here is a packed LYNformation 20. There has been a whole host of activity this month and much to report. So, without further ado, off we go!
1. Dates for your Diary: One.
Saturday 20th September. Alan Keef and Son open day at Lea Line, Lea, Nr Ross-on-Wye, HR9 7LQ.
This is usually a fantastic day out, with lots to see and an opportunity of visiting Alan Keef's very interesting facilities near Ross. There are always several trade stands as well as visiting steam engines to see. The 762 Club will be displaying many of the recently manufactured parts for 'LYN' and will have a trade stand. There will be several LARGE items to see, including the finished driving wheel sets, blast stand and weigh shaft. Do come along and see progress. I will be on duty that day, so it would be nice to meet any member or supporter who can make it.
I am pleased to feature a series of photographs of our cylinder block being made by F W Frost and Sons. It is the biggest contract we have let to date bar the boiler and it is making solid if a little delayed progress in Norfolk. As you can see, they have made several of the large components that make up the cylinder assembly and have all of the material on site bar the liners. Further progress will be made during the end of August and into September, but it is unlikely to be ready to display at either Gala this Autumn. Once it is finished, the whole assembly will be shipped to Alan Keef's, ready to be assembled to the frames and saddle.
3. Calling all Fabricators (and other forms of metal bashers)!
So far, my regular request has been for machining companies who would like to make some parts for us ( FOC or mates rates). Now, as we approach the reverser assembly and other sheet metal parts, there will be a need to make more parts using profiling or fabricating skills. These are more suitable for bending, welding or manipulating steel into the dozens of parts we will need soon.
If there are any members who have access to or run their own fabricating firms, we would love to hear from you.
4. Dates for your Diary: Two
Saturday 27th and Sunday 28th September. These are the dates for the Lynton and Barnstaple Railway's Autumn Gala at Woody Bay.
The 762 Club will have a sales stand as usual, and will also be displaying a variety of new components recently manufactured. Most of these parts will be recently made parts for the valves and motion. Of special interest will be all FOUR rods. These will be the two connecting rods and the two coupling rods. Although not fully assembled, the basic rods will be finished and ready to show. They have been made by the North Devon firm of Luffman Engineering who are based near Tiverton. Luffman will also be water-cutting our cross heads and there is a fair chance that these will also be on show, albeit un-machined. Come along and discuss with Jon Pain, Martin Swainson and Peter Miles about LYN's progress and maybe to buy some of our brilliant new Christmas Cards.
5. Spark Arrestor
As previously hinted, we are delighted to announce that the Wiltshire based firm of ALTEX have taken on the manufacture of the spark arrestor assembly free of charge.
This important assembly comes in two halves and protects the lineside from hot ash and embers being ejected from the blast pipe. The construction is a steel frame with stainless steel mesh tacked to it. They need to be removable and rugged. Once the spark arrestor is complete, the only thing remaining in the smokebox is the main steam pipes, which cannot be installed until boiler and frames are united.
News from David Priest is that the lamps are pretty much finished and we are now seeking the lens. Peter Miles thinks he has found a supplier to make the lens and we hope to have these two iconic items ready soon.
7. Reverser Stand Chassis assembly
Attention is now moving towards the reverser assembly. The final drawings have not been released for the full assembly but several of the bought in items have been specified and bought, and we have had the go ahead to make the reverser chassis assembly. Take a look at the drawing A3-LYN-059, and see the sturdy frame which will sit inside the cab on the driver's (right hand) side. The reverser is a modern screw type assembly which will allow for safe and easily controllable use of the valve gear. The chassis is steel and made from six separate plates, formed and welded. We hope to place this order soon (or it may even be placed by the time you read this).
8. Blast Pipe Nozzle
Down at Alan Keef's, they are busy with the blast pipe stand. The complete assembly will be ready for display at their open day, but the most important part has been delivered already. It is the Lempor Kordina top nozzles.
This intricate and expensive machining forms a cone with four separate tubes to increase the drafting and improve the creation of a vacuum in the smokebox. This 21st Century improvement will give greater efficiency and economy to LYN's working.
9. Wheels and Axle Boxes
Also at the centre piece of the open day will be the driving wheel set fully assembled with the fly cranks, axle boxes and spacers. Here is an image of the wheel sets with axle boxes machined and ready to fit.
10. Axle Box Spacers
In the assembly of the wheel sets, there are a whole variety of small(ish) components and the latest of the Alan Keef production line are the 8 spacers, beautiful modelled by Phil Kent of Keef's!
11. Reverser Handles
As already mentioned, we are well into the reverser stand now and orders have been placed with several suppliers for bought in parts. All of the handles were snapped up from the sponsors page recently and here they are!
12. Sand Pipe Hoses
At the same time, we are very pleased to say that supporter, Tony Conway, has kindly agreed to make the sander box's for us. There are two of these and we will feature these parts in greater detail next month. However, the pipes that connect the sand boxes on top of the boiler to the sand jets under the wheels are rubber hoses.
We have been lucky enough to attract sponsorship for these hoses from Abbeychart Limited. The hose has been delivered and here is an image of what it looks like. (Eh, it's just rubber hose! Editor)
13. Expansion Links
It will be touch and go if the expansion links are completed by the L&B Gala but they are well on the way to being finished. Here are two images. They are most generously being made by ND Precision Engineering of Barnstaple.
14. Reverser Screw Bevels
Orders have been placed for the four bevels we need to link up the reverser, and these should be delivered during September.
That's about all for now, but I am pleased that the pace is quickening. Just one point of caution: We are close to outstripping the design team's capacity and there may be some delays as the pony trucks are proving to be a long and exacting section. We will know more on this within the next six weeks or so.
Still, great progress this month!
Remember to take a look at the Component of the Month, and there are still some Christmas Cards available!
Well that's about it until next month!
