    19/01/2025 – Tank Pipes

    Hello and welcome to another cold weekend update from Quorn. We have reassembled a vacuum cylinder and started manufacturing the vacuum piping for the two TTA Tanks.

    On Saturday morning The Class 50 arrived to collect the van train from the yard in preparation for next weeks Winter Steam Gala.

    Ross fitted a replacement coil pack to the small petrol generator which was then successfully started up. This will be a useful addition to provide power for small tools etc. when we are working away from a mains supply in the yard for example.

    Ross and Ernie then got started selecting suitable pieces of vacuum pipe and modifying lengths and elbow joints to produce the main stepped section of pipe for the first TTA, some heat was necessary to release old joints; the pipe was trimmed to length and new threaded sections cut before assembling.

    The stepped pipe section was trial fitted to TTA 60874 along with the swan neck hose adaptor on the headstock.

    On the vacuum cylinder that had been started a couple of weeks ago, the release valve mounting threads were cleaned up using a die-nut. The piston rod gland was removed, studs cleaned to and the seal replaced with a new one.

    The cylinder was then re-assembled, firstly fitting the piston adaptor that allows a piston rod to be fitted from the top to aid lifting it into place. The rolling was carefully fitted to the upper edge of the piston then the piston was lowered into the cylinder, with a little jiggling to get it to go down evenly.

    The dome was then re-fitted with a new sealing ring and the securing nuts torqued up.

    A transport screw was fitted to the vac cylinder to keep the piston in place preventing damage to the rolling ring, this allowed the cylinder to be turned as necessary for scraping and wire brushing. It was then cleaned before being given a coat of Red Oxide primer.

    A second stepped vacuum pipe section was prepared for 60879.

    Sunday was very much a tidying up day, although some progress was made with cleaning up the final areas of the south end of the GUV, then applying Red Oxide primer to the metal parts.

    The inside of the Mess Coach and GUV were both given a good tidy up along with sorting out the taps and dies that had been recently donated.

    Once the Red Oxide had dried on the end of the GUV the wood areas were treated with wood primer.

    The two TTAs had their vacuum pipes removed when in main line service many years ago; along with the pipes some of the multi pipe brackets were cut back. It was therefore necessary to remove these brackets to allow us to make and re-fit the missing sections that will hold the new vacuum pipe. Some bolts un-did easily whilst others needed the grinder treatment.

    Using a piece of scrap plate of the right thickness, sections were cut, dressed and bent to form the vacuum pipe part for each bracket. These will subsequently be welded to the existing brackets at a later date.

    01/12/24 – Wash and brush up

    Hello everyone, and welcome to another update from Quorn. We’ve been able to progress a few jobs this week, with mechanical work culminating on the Catfish, the GUV has had another coat of paint and the coaches have been cleaned.

    Continuing the progress on the GUV, the last few patches of GUV were cleared back to bare metal, then sanded and primed. Dan, Ernie and Tom concentrated on fixing the loose body side rubbing strips.

    Reflecting the fact that the Catfish are cosmetically finished, Nick got them ready for a vacuum test by fitting vacuum hoses. We had also made a start extracting two sheared bolts in the hopper door on DB983393, which need to be extracted to refit one of the door mounting saddles.

    I continued looking at the generator and replaced the starter solenoid and double checked the timing, hoping I’d find the cause of it not running, sadly at the end of Saturday this was not the case, but I put the battery on charge for the night.

    The rest of the team made good progress and got the west side of the GUV covered in undercoat, ready for a coat of maroon gloss when the weather allows.

    Sunday’s weather started on the wet side. Mark and Tom did the usual gutter clearing, after noticing the water running down the side of the two coaches. After the worst of the rain, the pressure washer was used to jet the gutters, after which the coaches were cleaned using a bit of snow foam. On the west side a look out was used to ensure the group were away from the running line.

    I did a little bit more on the generator and got it running, which is a huge step given were we were with it some time ago. There is some fettling to do with the idle speed and fine tuning of the timing before we can put this back into use.We are starting to look at some improvements to the generator like an electric lift pump and maybe an alternator instead of a dynamo.

    We’ve ended the weekend with two clean coaches, a running generator and the GUV in undercoat on the west side. We’ll see what the weather brings next week, but we should are looking at completing the mechanical work on the two Catfish and hand paperwork over the Carriage & Wagon to begin their acceptance.
