Work party reports 29th June and 14th July

On 29th June a long-running sub-project within the electrical restoration of 50030 took a substantial step forward. I got the proper reverser (Class 50 specification) fitted into Repulse, with help from Dave Rolfe, Peter Carter and Ian Kemp as it's so damned heavy. We had to jiggle it about to get it to fit properly, but did it in the end. I attached the divert cables at the rear, but didn't have time to do the auxilaries at the front as I showed two visitors round Repulse. We are always happy to show enthusiasts around our project so if you want to take a look inside our locomotives then get in touch with us either via the website or our Facebook pages and we will do our best to accommodate you.

Also on this date Dave, Ian and Pete also continued sorting fuel and water pipework recovered from 50030's power unit to replace damaged sections on the ex-50008 unit.  This unit is destined for use in 50030 when complete - the existing power unit in Repulse was in acceptable condition when we acquired the loco, but has high engine hours and as part of our policy of overhauling our 50s to a very high standard in order to give them a long and trouble-free career in preservation we decided to overhaul one power unit totally.  The existing unit in Repulse will be re-used inside 50029 because the engine in Renown has serious problems following the seizure which ended the loco's BR career.  We don't know for sure but are aware of the possibility that the unit in 50029 may only be usable as a source of spares.  Power unit work can be one of the most gruelling of the practical restoration projects as the same task often has to be done at least sixteen times, sometimes even 32 or 64 times!

On 14th July I attached the reverser auxiliary contact wiring after showing another visitor round Repulse. Meanwhile, Ian, Pete and Dave fitted the fuel feed and return pipes to the ex-50008 power unit that they had previously salvaged from the power unit inside Repulse.

Work party report 15th Jun

Work party report 15th Jun

As it rained almost all day yesterday, even though the forecast was for dry weather, I decided not to cart the reverser outside as I've cleaned it, so I test fitted the newly-made CU2 field divert and CU7 ETH detector units into 50030's elec cubicle. While the CU7 can go in its original position, the original position for the CU2 had the cable connections very close to the cubicle frame, so I drilled a couple more holes to put it in a better position.
 
Inbetween the heavier bursts of rain, Ian and Pete removed the fuel feed pipes from 008's power unit as they'd been bent during the lift at Crewe when we bought and moved the PU about 8 years ago. Dave was painting pipes taken from the PU inside Repulse to replace them.
 
I also took the opportunity to get some more pictures of Mark's work last weekend on the generator conduits.

Work party report 7th June

Work party report 7th June

Dave Rolfe and I had a very wet Saturday at Rowsley last weekend (I'd gone on the Saturday as Sunday was my Wedding Anniversary), the weather finally cleared around 5 o'clock!

Given the weather we both found things indoors to occupy ourselves, Dave spent part of the day unbolting and freeing off sections of the radiator louvre operating mechanism. His remaining time was spent sorting out the various fittings, clamps, etc, that are needed to refit the fuel rails to the power unit, and checking their condition, cleaning and painting the metal sections of the clamps. I spent most of the day in 50030's generator room sorting out the best sections of conduit, from our collection of bits ex-50023, 50030 and 50040, to make up the remaining set of conduits. By the end of the day, I had cut sufficient sections to lay out the last of the conduit runs, all that remains to do now with this job is to strip the years of paint and dirt off them, thread the ends of the cut sections and fit the relevant couplers and locking nuts. Hopefully another day's work should see the conduit conundrum resolved. In the process I also identified ¾ of a set for one side of 50029.

Work party reports 25th May and 1st June

Work party reports 25th May and 1st June

If you've been following RRRG for some time, you might know that we have in our spares stock a genuine Class 50 reverser and a Class 37 example, which is similar but not identical to the Class 50 part.  We had removed the genuine 50 reverser in order to use it as a template to modify the 37 item to Class 50 spec, and in the meantime the ex-37 reverser was installed in 50030's electrical cubicle so that I could judge how long to make the wiring whilst rebuilding the cubicle.

On Sunday May 25th I disconnected the main cables from the back of the ex-37 reverser, and with Dave Rolfe's help, got it out of 30 and into the container. I cleaned the main power contacts on the the proper 50 reverser and labelled each contact bar while Dave was finishing drilling out sheared bolts around the removable grille that gives access into the No.1 end clean air compartment. Whilst cleaning I happened to notice the auxiliary contact blocks appeared to be facing the wrong way, so I went to Washwood Heath during the week to check 50008 Thunderer, and found they had indeed been refitted the wrong way round after we had taken them apart to make a replica second set to modify the 37 reverser for use in 29.

Whilst working around the cubicle area in 50030, I was impressed by work that Mark Burrows has been doing to restore the cable conduits for the traction cabling to the main generator.  This has been a laborious task using the best parts of conduits salvaged from 50023 and 50040 before those locomotives were scrapped a few years ago.

On 1st June Ian, Pete and Dave refitted the decompressor plugs into the power unit, then spent the rest of the day cleaning parts of the power unit ready for painting.

On the same day, I removed the auxiliary contact blocks from the Class 50-spec reverser and fitted them the right way round, in the process realising that the internal cams had been rotated out of their correct positions, so they wouldn't open and close in the correct sequence. The afternoon was spent getting them back into the correct alignment.  Now that the reverser has been properly adjusted, my next task will to fit it back into the electrical cubicle in 50030.

Radiator mounting nuts

Radiator mounting nuts

No, we haven't packed up and ceased to exist.  Yes, we have been a bit quiet.  Sorry about that - normal service to be resumed but a number of us have had things other than RRRG to deal with and our day lives have got in the way.

 

Ian Kemp and Dave Rolfe decided today to tackle a job we started some time ago but ended up leaving to another day.  This was to remove the remaining radiator securing nuts, so that we can lift the radiators out of 50030 and have them sent away for overhaul.  Given that the radiators were most likely last removed at refurbishment in the mid-1980s it goes without saying that the fastening nuts were stuck on very firmly indeed.  We had previously managed to remove three of them, leaving five left to do.  A potent combination of elbow grease, tools (and broken tools), purple language and in the case of one particularly stubborn nut, chiseling has now freed all eight nuts and the radiators can now be lifted out.  It's the seemingly little tasks like this that end up taking so much time.  Photos courtesy Ian Kemp.
