The tyre and Gibson ring being riveted to a wheel at South Devon Railway - Rob LeChevalier

 

Friday 14th July 2017

Latest update from the SDR

All tyres fitted. Rivets now in stock for fitting to the tyres. This has been the cause of limited progress this week.

The front wheel set is in the lathe the journals are within 0.007" of true. This is acceptable. The journals and boss faces are being polished there will be a small charge for this.

Harry Frith is going to NDT the wheel sets on the 24th.

By the end of next week we expect good progress to have been made on the riveting of the tyres and profiling of the wheels. We are looking at delivery being in the first week of August.

A very wet and miserable day at Grosmont today, with Derek, Jon ,Ian Chris and Nigel. Not a great deal to report today, Nigel continuing painting the frames two coats of primer applied to each side. Derek has cleaned all the rubbish from the inside of the drag box and found a spoon and the missing metal ticket from the" Staff & Ticket" section Newbridge - Levisham ,which was lost about two years ago. Jon and I assembled the L/H valve together loosely keys still to make for these valves.

Another Day at Grosmont, with Bryan Orange and the JV's, Peter Ellis, and Ian Pearson.

Well after the usual cup of Tea, Bryan sorted where the JV 's were working and gave us Tom Noble, who did a great job of cleaning the L/H valve spindle and its rusty key way. he also cleaned the Dome ring after Peter had annealed it.

Peter annealed the four remaining oil pipes from the driving boxes, and also fitted the trailing oil pipe which had been renewed. The new steel pipe was fitted to the blow down valve by Peter. I completed cleaning the back plate from the L/H valve.

Lunch today was outside Deviation shed a little cloudy but fine.

After lunch Peter and I set about removing the sheared stud on the dome it was cut down with the angle grinder then drilled through with a succession of drill bits until we ran out of drill bits , so asked Phil Naylor who was duty fitter if he could help. He flushed the remaining metal out with the burning torch, then punched out the last piece of metal "Thanks Phil." This will need re-tapping for a new stud next week.

Neal Woods called in this morning he is going to get a new ring made for the R/H piston valve. Time to pack up and go home by for now.

Winter Maintanance reaches Mid-Summer

A warm muggy day at Grosmont today, with Derek Shorten, Jon Bradley, Nigel Hall & Ian Pearson. Also Gordon Wells fitting conduit and a couple of sockets in the pit.

After a cup of tea a slow start was made on progressing today's work load, Derek Setting up the lighting down in the running shed and taking the equipment needed for final cleaning and painting of the L/H frames. Jon & I replaced the remaining Klinger packing top R/H. Then onto boiler dome to remove the broken stud. This has had a nut welded onto it, so eventually we found a socket that fitted this nut 30mm . A long pipe was attached to the socket bar and after about 4 attempts to remove the stud it sheared again. I have left this job until Saturday as it may need drilling out ,plus the fact there was someone working in the boiler assisting the boiler smith tapping the flue holes in the tube plate. In the meantime Nigel got started with the painting and by the end of the day the left hand side is now all primed.

Lunch was going to have been on the bench outside Deviation shed but as Nigel was about to take a bite of his sandwich the heaven's opened torrential rain came down so lunch was inside Deviation shed. The rain was hammering down and it wasn't long before it was flowing under the side door through the workshop and out into the pit.

After lunch the remaining four Spring hanger adjuster bolts which Chris Parrish was re- cutting the damaged threads were brought back to the workshop and are now on the bench with the others, he still has one nut that needs some attention but will be ready on Saturday. Had a word with Piglet re NDT of the hanger bolts he is trying to get this done soon!

At long last the L/H back plate has been removed ,thanks to Shaun Bowler and his mate (railway fitters). it was taken to the press with about 10 tons of pressure and quite a bit of heat it eventually started to move free. No wonder it would not move the amount of rust holding it. I don't think it had been off for many years! see photo's, Jon and I started to clean the back plate and spindle still needs some more cleaning.

Extremely hot sunny day at Grosmont with Colin Foxton , Peter Ellis& Ian Pearson.

RHS valve plate showing keyway - Ian Pearson

The R/H valve was put in the vice and after half an hour the key was removed, Colin realised that the key had been put in the wrong way. These keys have a slight taper and need to go in taper first this was not so and causing the to jam. These keys seem to be short in depth so they do not hold anything! See photo. When R/H valve was stripped down it was found that the back valve ring has a broken lug. See Photo ,New ring required. The valve has been reassembled and is on the bench for further investigation and repair.

The L/H valve has had part of the broken key drilled out by Colin and some heat treatment from Peter and an attempt to remove the back plate from the valve spindle but it wont budge. We may try the press on Wednesday?

Bill Dobson called in for chat and a cup of tea showed him the valves and explained the problems we are having.

I replaced 2 more klinger packing's on the gauge frames ,one left to change top R/H.

Lots of competitors for the railways" race the train" today which started at 2pm on the old track bed opposite Deviation shed , a bit hot for running to Goathland and back to Gosmont! We packed at 2.30 and called it a day.

 

Wednesday 14th June 2017

A hot sunny, but frustrating day at Grosmont with Derek Shorten, Nigel Hall, and myself (eventually, after a call in at Pickering on the way), with Ian Pearson in charge. Bill Dobson joined us for a few hours and Terry Newman paid us a visit at teatime.

Derek and Nigel worked all day in the running shed, Derek cleaning the brackets of the LHS frames and Nigel sanding down both sides of the frames - these are now almost ready for painting. I was found employment filing a small piece of steel to make a new key for the left hand piston valve: still a bit more to do to finish that off - it is on the bench by the RH piston valve. The shed staff have welded a nut onto the broken stud on the dome and Ian had a go at its removal. It would not shift though, and against the possibility of it shearing if more pressure was applied, it was abandoned for the moment. Barney, the chargehand fitter, checked the gauge frame gland nuts. These were assessed as now OK after cleaning the top left hand one with a thread file, and the Klinger packings can be fitted on Saturday.

We had our lunch outside Deviation Shed on the bench, sat in the lovely warm sunshine watching the trains go by and giving Jon Bradley a wave.

Quite a lot of visitors round the shed today: must have been the warm weather!

After lunch Ian and I, with help from Bill, had a look at the left hand valve spindle with the broken key jammed in the key way, but decided to leave it for the time being . So we started to strip the right hand valve to try and get the valve ring free when the nut is tightened by putting extra shims in. After removing the nut and front end of the valve, the cone shaped piece has a key in it, but in spite of several hours effort trying to remove it, it proved impossible to get it out and we had to retire, frustrated and hot.

The NYMR is in the process of making a couple of valve stands, and the conduit for the electric cables for the pit lighting has been delivered and is on the Shed floor by the workshop. Mark O'Brien has yet to finish the firebox flue tube thread recutting, as absolute priority is being given to getting Repton finished (the boiler is now full of water), but his plan is to have that work finished and the completed flue tubes at Grosmont by the time the wheel sets come back from South Devon Engineering.

 

Saturday 10th June 2017

Colin Foxton, Paul Swainston, Nigel Hall, Brian Orange and the JVs.

On arrival the left valve rod was spotted forlornly leaning up against the wall next to the press in the running shed with the last piece of the head and broken key still firmly in place. So back to deviation shed. The rest of the elements of the left valve rod had their mating faces thoroughly cleaned with help from Paul Swainston at the end of his NYMR cleaning shift. A trial assembly of all the elements on to the rod was tried and a similar problem experienced to the right hand rod where once the nut was fully tightened both valve rings were solid. So whether or not the elusive key is removed this issue of the rings not being free on both valves will have to be examined further. Time to go home after varying attempts with penetrating oil, paraffin and gentle persuasion, you guessed it, no movement so the rod was left in the vice outside the workshop with the outside of the head uppermost and the well full of paraffin. Hopefully by next Wednesday or Saturday the situation may have eased.

In the running shed we continued with the cleaning of the RHS frames, assisted from time to time by Bryan and a succession of JVs. By the end of the day we had them free enough of grease to make the first pass with the orbital sander. Hopefully the LHS is in a fit condition for the orbital sander on Wednesday too.

The rain lashed down. All that was needed was the swarm of midges for it to be an August day in Ft William.

Neal Woods (driving) and Bill Dobson visited us during the day.

 

 

Wednesday 7th June 2017

Todays working party Ian Pearson, Jon Bradley, Derek Shorten & Nigel Hall.

Mark o' Brian asked me if we could re-fit the fire grate to give him better working base in the firebox for the work involved in re- tubing the boiler. Jon & I carried out this task the front section of the grate was moved in a barrow and fitted , we got the Telehandler to bring the back section down to the shed much easier, and got that fitted after lunch. We then removed the oil pipes and brackets from the frames which feed the driving axle boxes these put in store up stairs. Derek & Nigel continued cleaning the right hand frames, still some more cleaning to do. The left hand valve is still in the press no more work has been done on this. Some of the gauge frame gland nuts are quite sloppy on the threads these need to be examined. Four new Klinger Packing's were obtained from the stores last Saturday only one Klinger packing was fitted to the top left gauge frame last week, the rest are on the work bench in deviation shed. No point in fitting any more until the gauge frame gland nuts are sorted.

I will not be at Grosmont this Saturday10/06/17, Nigel intends to go and continue cleaning & painting so contact Nigel Hall first if any one would like a day out at Grosmont shed .
