Happy Faces

Normally we share our locomotives and trains to the delight of the younger generation but on Tuesday we had the pleasure of giving rides to some older people who were equally excited and showed a great deal of pleasure.  These were a group of disabled who were brought along by DCF Premier Workshop, which is a charity in Bristol looking after some 50 people during the week.  It does a tremendous job and aims to provide them with an interesting experience with activities in the workshop and on outings.   I have to say the pleasure on the faces of these folk who struggled to get on the carriages and then enjoyed lap after lap round the track was a pleasure to behold.  We all have great fun with our hobby and it is a treat to share it and see others also get so much enjoyment.  Thanks to all the members who turned out to assist on such a very rewarding day.IMG_0478

5000 Laps 1550 Miles

IMG_0481

 

Yes that is correct.  On Sunday the Western Britstolian Class 52 locomotive completed 5,000 laps and nearly 1,600 actual miles.  That is the distance from John O’Groats to Lands End and back – can you picture it running all that way alongside the M6.

The loco was purchased from Phoenix and first took to the track in May 2007 so has been working away for some 6 years.  Initially it was somewhat lacking in power for club use, hauling passengers, and this was overcome by fitting new motors with a new controller.  Following the upgrade it has given excellent and reliable service and can be seen being driven by Martin Mortimer-Fox on most running days.   You can see from the photograph that with the excellent care given to it by Mike Keighley and others it has kept in remarkably good condition and is a splendid asset in the service of the club.

PS   Alan Church has asked me to point out that the rubbish disposed of by our chairman does not include his Irish loco.

The Workshop in Action

IMG_0461

Daniel Hamilton came with his dad Donald to the auction on Wednesday evening at Ashton Court and asked if he could come along on Friday to do some work on a Go-Kart he is building.  This is Daniel at work on one of the stub axles under the watchful eye of workshopmanager Phil Bridgeway.  Daniel had already done some lathe work at school but no doubt learnt a lot from Phil who introduced him to turning between centres.   It is  delight to see the machinery being put to such good use and Daniel will be back next week to make some more parts.   The go-kart will be powered by a Honda look-a-like engine and Daniel has already completed the front end.   We look forward to seeing the kart in action.

 Alan Church with 3 1/2 F

IMG_0455Alan Church brought along his scratch built Gauge 1 engine and tender.  It was intended to be a 4F but Alan got the dome in the wrong place so now it is a 3 1/2F or as Alan puts it an “Irish” engine.  Wheels came from our sale last year and the rest from Alan’s scrap box –  he must have a IMG_0456big scrap box.   Based on “the project” it has single cylinder with slip eccentric, water pump and is exquisitely made to a total cost of £30.  We have got some clever b’s in our Society.   Not sure what contribution our chairman was making but it is good to see him at the track because he takes a lot of rubbish away.

  Mike Keithley and a Polly Tender

IMG_0464

Mike Keithley brought along the tender of the club’s Polly  – yet another smashing piece of work – spoilt with things to photograph this week.   He and his team have been working hard , particularly on the paint work and this made it quite difficult to photograph with the bright sun reflecting on the highly polished service.   Looks too good to me for the members to use, I think we will have to get Frank Gibbens to make a glass case for it! .

More Action

IMG_0470

There was a lot more action with a very good turn out of members enjoying the sunny day. David Giles was working on the paved area around the new lift and a boiler awaits test.  The tailstock die holder and dies were purchased at the auction on Wednesday night for the club workshop.  We are building up quite a collection of tools to go with the machinery.

It is about time I had a holiday so I am away for the next threeFridays but will try and get some news to you.

Signals  -Tuesday update with Pictures – It WORKS!!

IMG_0454

Busy day at the track Friday and Tuesday.  Now the ground level track has been re-layed leaving the station through to the bridge we no longer have metal ties joining the rails and we can have track detection to see if the  track is occupied.  The detector can then be used to operate a signal at the station which will inform the driver when it is safe to pull away.  Two purposes, firstly the vision is obscured by the hedge at this point and it is not easy to see if the track is clear and secondly it adds to the railway “atmosphere” and gives something more for passenger  to watch – they seem quite taken by the various signals.

IMG_0446IMG_0447

Work started early this year when I designed the system and brought the components.  These are mainly sourced on ebay which provides plenty of choice and good reliable service.  You have to wait a bit if the part comes from Hong Kong so you need to start early.  Having got all the bit these were put together into  a cabinet, the circuits tested and the cabinet bolted onto the wall in the station.  At the same time Mark Phillips was getting the bits and building the signals.  We will eventually be installing two systems, one for the ground level and one for the raised track but at the moment concentrating on the ground level.

 

IMG_0450IMG_0449

 

Once the track was in place Terry Phelps set to work welding electrical contact straps onto the rails with silver soldered bolts in the straps.  These are then joined together with wire loops to maintain the circuit across the fishplates. Roger Sykes, Derek Todman and I then pulled in the cables and today we completed the wiring to the signal which Mark had mounted under the bridge and also to the beginning of the new track where Mark and Terry had fitted isolating fish plates.

 

With me so far – I seem to be going on  a bit but there is quite a bit of work to be done.

On Tuesday, Mark and  I hope to get the signal working so next time you are down on a Running Day have a look – We did except Mark was at the dentists.

Why no pictures on Friday Well shortly after lunch three members from Stockport ME turned up. The are driving an old Lagonda from Lands End to John O”Grouts and as they were passing, called in on the off chance.  So, by the time we had chatted, given them a ride on Telford and had a cup of tea the afternoon had gone andI  had to rush and pack up.

Back from my fascinating tour of Eastern Germany including Berlin, Dresden and Colditz normal blogging service will now  hopefully be restored.

We had a great trip up the Broken in the Harz mountains behind this beast.  Specially built for the job they haul large trains up to the 3,000ft summit on narrow gauge track with no cogs. A splendid sight and sound.IMG_0336

We also visited the world’s largest garden railway – Eisenbahnwelton in Kurort Rathen – which included the Harz railway in miniature. Trains running everywhere, fully signalled, sound, uncoupling and running round at the end of the line etc.   We should have one at Ashton Court but perhaps not as big as this – you would have a job to fit it into our whole site – but the control systems would present a super challange.

IMG_0440

Back to our world –  on a brief visit I was pleased to see that Alan Hooper has been getting on with the new fence by the bridge.  A number of people have been concerned by the hazard presented by the unguarded drop and it is good to see it in position.  Alan has already given it a coat of creosote and he was not alone with the creosote brush.  There were five people all busy round the site putting protection on the various fences.   Not a pleasant job but one of many carried out by members to keep Ashton Court in such fine condition.

Following work by the track and bogie gangs we seem to have got on top of the derailment on the ground level track and had trouble free running over the Bank Holiday weekend.  Lots of locos, passengers and helpers.

Now we have planning permission for the workshop I am busy obtaining prices and quotes so that we can put together a realistic cost for the project and aim to have something by the end of June.  We can then get back to the members and get their views on whether to proceed.  Planning requirements are not too onerous but we will have to carry out planting to replace shrubs we remove and fit a bat box on the new building.

Doughnuts

IMG_0138

Three birthdays resulted in in  70 doughnuts arriving for us all to eat.  Needles to say all were eaten by the end of the day.  Fuelled by doughnuts and encouraged by the sunshine everybody was very busy.  Cutting the grass clearing  bushes, painting fences, checking rail and points there is always something to do.

IMG_0136

 

Three boiler tests, some including hydraulic, kept the testers busy and pleased to report all passed.  They seemed be well organised led by Bernard North and it was good to see John Milton and our latest tester Peter Pearson hard at work.

 

IMG_0137

 

We have been having a lot of derailments on the ground level track and are therefore bringing forward the replacement of all bogies on the older trucks which have been running for something like twenty years.   Good to see Mark Phillips back as he has been poorly for some time.  He was working withe Ron James and Phil Bridgeway measuring the trucks and preparing the design for the new bogies which will use rubber suspension based on the Ron James design and fitted with calliper brakes.

Having purchased a dynamometer module from Station Road Steam, Paul Keller their technical expert came along to sort out a few bugs and Bernard was busy measuring our dynamometer car to see how it could be fitted in.   It will replace the existing mechanical setup which has given excellent service and  bring  us up to date with the latest technology  using an  Android tablet or  phone to display the results.  Bernard and Don Cordall will working to fit it into our dynamometer car but not sure we can make the change before Brimlec on 3rd July.

IMG_0139

On Tuesday I visited Ashton Court and was delighted to find it being used by members running their locos –  hence the pictures.  There were five on the truck and they had a good run in the sunshine. After adjusting the anti tipping rail I took the opportunity to check all the raised rack carriages and all are bump free except No3 which Maurice Wheatley will be sorting.

Hope you like the new web site host – it seems a lot faster and easier to use.

Off for four weeks I look forward to all the progress made when I come back.

PS.  Have a look at the blog by John Chaddock it is excellent and I am sure all aero engine nuts will find it enthralling.  Well done John

Goodbye Geoff

 IMG_0132

Today was the funeral of Geoff Sheppard.   Held at Westerleigh Cremeatorium several hundred people turned up to pay their last respects.  Many friends and colleagues from the Model Engineers were there, together with similar numbers from  other Societies where clearly Geoff was held in the same high esteem.

A simple but poignant service was held in the crematorium followed by a well supported gathering at Kendleshire Golf Club where we were invited to celebrate Geoff’s life. His son spoke of the huge love and respect for him by the family and a number of humorous but touching eulogies were presented by individuals from the many and varied Societies he supported – mainly from the top.   George Ganley spoke on behalf of BSMEE of his long relationship with Geoff at work and and with the club and there were similar speeches by representatives from, Vintage Cars, Austin Seven, Heritage Trust and  BIAS not forgetting the Red Lion.  He clearly had a full and interesting life and was respected by all he met with his sensitive, personal approach, engineering expertise and ready support and assistance to so many people in so many ways.

He was a good friend, giving me much help and support, and for me it was a sad, sad day.

After Easter

A busy day today putting right some of the problems which occurred during our running over the Easter weekend when we had a very cold wind, very few locomotives from members and a reasonable number of passengers. 

The platform entry signals failed Sunday afternoon and this was tracked down to a failed microswitch in the treadle just before the main gate.  This was replaced today with some difficulty, because the soldering iron wouldn’t heat up in the cold wind, and is now working OK.

The signal men complained of cold feet so Andy Harding was busy laying carpet tiles in the signal box whilst Arthur Clark continued on repointing the brickwork.

The new section of ground level track had settled with all the use and required some attention by the track gang.  It is surprising how quickly people can work when there is a biting cold wind and they were soon back in the hut drinking coffee.

We had a number of derailments on the ground level track and Phil Bridgeway and Ron James removed the bogies for examination from carriage 202 which seemed to be the main offender.  Examination of the wheels showed that they are badly worn on the flanges and whilst an attempt will be made to reprofile them there is insufficient metal left for them to be turned to meet our specification.    It seems that we will have to bring forward our plans to fit all the “old” carriages with new bogies complete with the calliper brakes we have been experimenting with.  Work is now going ahead to produce a specification and drawings for the new bogies.

Maurice Weakley came along to work on the Raised Track Carriages and removed a faulty bogie from No7 carriage which has taken away to refurbish.  We still have quite a bit of work to do on these carriages – any volunteers would be most welcome.

Frank Buffham aided by David Ward (2) lit an enormous bonfire to burn all the rubbish.  We were very concerned about the exhibition shed going up in flames but happily all is well.

We have taken delivery of a dynamometer module from Station Road Steam and Bernard North found time between boiler tests to spend some time examining our dynamometer car to see how it could be fitted.  I will bring you more information on the interesting experimental project as it proceeds.

Finally, I did not have time to take any photos so you will have to make do with one of my Dock Tank with which a spent a very happy afternoon on Tuesday doing quite a few laps of the tracks.  Happiness is driving a steam loco in the sunshine, which has plenty of water a good fire and never runs out of steam.  Incidentally the new lift made things a lot easier.

A Day for Reflection

Busy getting ready for our first running day of 2013 but news of the loss of Geoff Sheppard meant that a there was a somber mood in the club hut.

Geoff was a pillar of support , a personal friend and will be sadly missed by me, the club and club members and throughout the model engineering world where he had tremendous presence and was known and respected by all.

Still work had to go on preparing and testing the rolling stock, signals and track ready for our passengers on Sunday when Ian Biddiscombe will be duty manager.  With the cold wind and threat of a sharp frost we felt it wise to leave the water turned off and we will have to go round and restore it on Sunday morning.  The forecast for the weekend is dry with some sun and hopefully the wind will drop and it it will be a bit warmer.  Ashton Court always seem to catch the worst of the cold wind,

I remembered the hot cross buns this week and they were warmed and eaten with our coffee and tea.     David Hathway checked out Telford and gave it run to make sure the batteries were recharged and tested the signals on the way round.  All ground level trucks are operational but unfortunately the testing team on the raised track found two faulty  trucks.  One had a seized bogie and the other fouled the rubbing rail  so had to be withdrawn from service.   Derek Taylor is working on two new carriages and this will allow us to overhaul the other trucks in turn.

Wot – no donuts

 

Bob's Birthday Card

Bob’s Birthday Card

Last week was my birthday but I was away and so could not provide the traditional donuts to refuel the workers at Ashton Court.   The problem was compounded because this week I forgot to get any donuts.   I was further embarrassed by being presented with a birthday card see above and have promised to set the matter straight by bringing “hot cross buns” for everybody next week so come along and enjoy one.  I have set my alarm to make sure I remember .

IMG_0096

I understand all went well on steam up day.   The lift worked and the ground level track was completed with a five mph speed restriction.   Following further work and inspection this week the limit has been lifted.    Well done to the GL track team. The next thing on this project is to install the new signalling system.   The Control Box is on the wall and Terry Phelps will be welding on the connection straps then the cables will be run and connected and the signals installed.  At present Mark Phillips, who is providing the signals, is poorly with vertigo and we wish him a speedy recovery.

A few brave souls   braved the elements today with Arthur Clark and Terry Phelps attending to the signal box, David Ward carrying on with the fence and Colin Ball and David Hathway cutting grass and tidying but most were keeping warm in the hut where David Giles had his British Record breaking 3.5cc tether car for us all to admire. Recorded speed was 241 kph or 150mph giving a pull of nearly one 140kg on the ether.  I wouldn’t want to be around if it broke free!   The design, build and attention to detail is superb and I have attached a few photographs – click on them to see the fine engineering.

Finally – how the club can help.  If you were at the meeting on Wednesday you will have seen our chairman Derek  once again demonstrating  his ineptitude.  This time by drilling holes in a casting which were out of square  for which he blamed the casting.  A few people were not sure the fault lay with the casting and after the meeting he was given advice by some more experienced members. This morning David Trotham turned up with a very sturdy adjustable angle plate to solve his problem.  There is always somebody in the club who can help – just ask.

Bar Stools Wanted

With a Tuesday visit to install the plywood cladding and the reinstallation of the signal frames and control box today, the signal box is now ready for action.

The operating conditions inside the box are transformed and we will no doubt have a queue of members who want to get in if just to get out of the cold and wet.   There is plenty of room to stand up  and the view of the track and station is very good indeed.   Thanks to Terry Phelps for coming up with the idea, taking the plunge and getting the job done before the start of the running season.  We have been promised a new carpet and the only remaining problem is that no doubt the signalman will want to take an occasional rest and sit  down.  If anybody has any stools that they are throwing out and think might be suitable please let us know.  It would be a shame to buy some if there are some about waiting to be dumped.

My blogs tend to concentrate on projects and big jobs but we shouldn’t forget all the mundane work which goes on each week to keep the track operational.  Alan Grinstead and Clem Culverhouse went off with cans to fill with petrol and Mike Keighley is busy organising the steam oil ready for steam up day on the 17th March.  Frank Gribben was repairing the station roof soffits and David Giles sorted the ground level track where it approaches the carriage shed.  This has been the cause of numerous derailments and frustration.   David cleared the stones and rubbish from the concrete gaps and points.  With his usual skill and attention to detail he dressed the leading edge of the points and made such a good job you have difficulty seeing the join – see photo.

PS.  Don’t forget to click on the pictures to get a better view – the resolution of the new phone is excellent.
