    If anyone wants to do that, please feel free. All welcome - it's a public meeting. Why not come along and 'Join the Clan'? See you there...

    It is indeed, though there do seem to be quite a lot of machining marks on it. Presumably quite within tolerance. Really looking forward to seeing all these parts assembled at Heywood!
    Any clues about car parking at Carlisle AGM?

    Very nice.
    I noticed this too...but like you I too presume within tolerance.

    Great to see solid progress. I'm keen to see the 3D sand printing for the castings.

    Engineering Director visited the manufacturers, CTL Seal, on Friday last. All paperwork for the parts available with regard to size, and all within acceptable tolerance. Without checking back to the drawing, which is extremely complex, I cannot remember the exact limitation.

    Sand Print mold is now at Boro' Foundry, so progress to show very soon I hope...

    Car parking in Carlisle: not looked as yet, but something I need to organise for myself, as I will be staying over night for the AGM. I hope that there is one near by - make life much easier.

    Are the visible machining marks simply more a case of the camera, as so often happens, being quite 'cruel'?

    I expect they probably are highlighted by camera angle and lighting conditions. Freshly machined steel has remarkable light reflection properties. My comment was purely a comment, not a criticism. (Would I dare ;)?)

    I see we have very interesting photos of the 3d sand mould on the Clan website. Well worth a look folks!

    It is indeed an elegant component.
    afaik Its as the original, no 'Improvements' we're deemed to be of sufficient value to warrant a change to the design. Don't think that substitution with the equivalent but slightly different Britannia item was considered ( for a non re useable mould what would be the point...)

    (The suggestion of extending a partition between the two sides of the apparatus to the base of the blast cone to form a crude ' kordina' was declined)...
    Is there something else you had in mind ?

    The Kordina is a concentric blastpipe combination, do you mean Goss' separation partition to force parallel flow?
    Kind regards

    Prevention of exhaust back pressure from one side adversely affecting the other I think Jos. Benefits were found to be too small to warrant the extra investment.

    Yes Jos wasn't aware that a Kordina was exclusively a Coxial arangement but yes aka a 'Goss wall' intended to impart a similar benefit.
    This feature would of course have enabled this component to be produced as two halves (or even 4 legs). However the problem of producing it in one piece would seem to have been solved...

    Yeah, however the original explanation of the Kordina device is to be found in The Engineer of 1888, not in a text by Wardale.
    See my contribution #976 of Feb 8 in this thread.
    Kind regards

    Exhaust Steam Spider has been cast. This is the raw casting. Now needs to be heat treated, before going to CTL Seal for assembly and machining as part of the smokebox saddle. Image: Boro' Foundry

    It's good to see the steady progress being made on this project, steady and right for achieving the ultimate goal!

    Hi I have just come across this bit on NP so I wonder if it is possible for some one to do a summary of this project and where about's it is in the long term and does anyone have a time frame as to when all these bits get bolted on to the main frames?

    I read some where last year that you have moved all your bits from Somerset to a new location how did that go?

    Thanks in advance for bring me up to speed.


    Regards

    Colin Rainsbury

    Its almost the other way round with a Clan, the main frames get bolted onto all these bits ( subframes, stretchers etc...)
    Sure there will be an update at the AGM but its looking like 'almost there' for major components. Expect frame assembly work will start this year - funds/contractor capacity permitting ... ?
