Life in the Signal Box

It was a hot day on Sunday but we still had quite few passengers and lots of engines on the raised track.

As you will know if you have tried it, life in the signal box can be hard work. You need an alert mind and nimble fingers to keep up with the demand.   Which track to put the next train on the loop or the main, now the bell rings to tell you that a train has just left the platform and you must lower a signal to call on the next train then reset it when the train has passed.  Then you get three bells and having made sure nobody has gone past the box you put the traverser signal to danger to allow operation of the traverser, now two bells to say the traverser is clear so off with the traverser signal, by now another train is approaching on the ground level track and so it goes on.

Mike Keighley found himself in the box all day and it was very hot

The funny thing was the trains seemed to continue running – no one had the heart to wake him up.

Hope you like the new format  for the web site which has been introduced by Harrison Fletcher.

BRIMLEC

On a sunny but chilly  Wednesday evening, members gathered at Ashton Court.  Quite a good turn out of members but unfortunately this was not matched by locomotives.  Only Gordon Cackett brought along his engine and he also allowed Pete Goodman to have a go and see what he could do.  Both drivers had great problems with wheel spin which they put down to an oil leak which occurred on the last running day. Gordon struggled round with himself, and three passengers whilst Pete started with the same number of passengers but soon found he had to drop David Harding and continue with two.   The provisional result , subject to final analyse and scrutiny was a win for Gordon with 0.9% and Pete coming second with 0.6%.   Shame there were not more engines but there was a lot of chatting and much  tea drunk.  Unfortunately the club loco was out of action with a broken grate,  We must make sure it is available next year so we can have a full test of drivers if not of locos.

Tuesday Steam – Can you identify  the Headless Driver?

IMG_0489

As often happens these days a few members turned out on Tuesday to run assorted trams and steam engines and enjoy a cup of coffee and natter.  A new member turned up and enjoyed some laps of the track.  Dennis is re-building a Polly 4 and looking forward to his retirement when he can spend more time at the track.    He is keen to learn more about using a lathe and milling machine he has recently purchased and has offered to help at the exhibition.  Mike Keighley spent the morning clearing ants nests.

Clue to headless driver – he has recently been castigated for the shocking state of his car!

 

Polly Boiler – can it take the pressure?

Pickle saved the day! Following my misshap with the steel washer in the old pickle (see comment on previous post) a further week in fresh pickle reversed the copper deposition.

Also the silver solder finally flowed. The improvement was down to using more flux and using a bigger burner to get the temperature up quicker.

The finished job may look a little messy to the more experienced practitioners out there, but to me it looks lovely as it’s my first sucessful boiler build 🙂

Now I like to say it held pressure on its first test, but that would be a fib. Two of the bushes leaked when I tested it initially at 10 psi immersed in a bucket of water. The answer? MORE SOLDER.

It has now been tested to 30 psi and not so much as a nano bubble escaped – phew

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.

Clicking on the pictures should blow them up – it does and gives a black screen!!  Back to the experts.

Polly Brazing

What did I say about luck and a fair wind?

The solder around the base ran as expected. Dead easy this soldering! I don’t know what people go on about.

So on with the base of the chimney. Heat up, watch the flux melt and go clear touch the solder on……. nothing. More heat then…. nothing MORE HEAT……. still nothing HEAT HEAT HEAT HEAT and yes – still nothing. Out of luck. Dang it!

It all went into the pickle to try again the next day (well today). This time the base went on fine.

Dead easy this soldering, I dont know what people go on about.

So turn it over and lets do the top. I just about managed to get the top of the chimney done and one of the bushes. The other two bushes and the rim of the top, Nope. Nothing doing. Rien de rien.

The /^&/$@#/ thing is back in the pickle now ready to try again tomorrow.

Tubal Cain’s Polly

I am taking part in the SMEE course for beginner Model Engineers, the course covers the building of a small boiler and oscillating engine to the design ‘Polly’ by Tubal Cain.

The boiler is designed around a tube of copper with formed endplates and a central chimney that doubles as a stay. Brass bushes are placed in the top plate to hold a safety valve, steam pipe and filling point.

Here is my progress so far.

image

Cutting the end plates from sheet

image

Discs held on an mdf base for drilling the central hole

image

I had heard lots of horror stories about drilling sheet but using these drills it was no problem. Not a triangular hole in sight.

image

Here you can see a part formed disc and the next one to be formed fitted to the former. The ball pien hammer was an old abused one that I cleaned up with emery and then polished up on a buffing wheel bought at one of our auctions.

image

And then it a case of beat, anneal, clean…… until formed.

image

All the copper parts complete. The holes for the bushes were drilled using the drills shown previously and the holes for the chimney were opened out with a boring bar on the lathe.

image

And here are the bushes turned from brass.

My next step is to silver braze everything together. I got a few sticks from Ron at the last meeting and the only thing holding me back now is a little trepidation but with luck and a fair wind it will be done tomorrow.

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.

 

Bob’s Blog is Back

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.
