    I hope this thread is OK with the Admin.

    At work (I work for a boilersmiths) we've been making odd bit's and pieces for Austerity boilers for years, usually as "1 offs".

    I've orders in at the moment for a couple of Austerity backheads, and we've made quite a few in the past (Austerities are known for cracking backheads, to the point that on any given Austerity boiler, it's usually not so much a question of "is the backhead cracked?" as "how badly is it cracked at the moment?").

    Given the constant dribble of orders for Austerity backheads, we're looking at setting up our big press with 2 part tooling to form them, rather than hand forging them. Even once we've bought the tooling, each time we set it up on the press is a fairly time consuming (and thus expensive) operation, so I've been wonder if rather than setting the tooling up every six months when someone wants one, there might be interest from various Austerity owners in manufacturing a largish batch of backheads for them to hold in stock until their loco is due a major boiler overhaul. If I could get orders for 10 I think we'd be able to knock about 20%-25% off the usual cost for making one at a time.

    I've no idea if there is any interest, but given there are 77 odd of the things kicking about in preservation I think this could possibly save some owners a good deal of money.

    Backheads aren't the only items this might work for - we periodically get asked to supply Austerity smokeboxes, either as kits of parts or assembled - again, if there was interest in a batch of 5 or so, there could easily be some savings to be had getting components profiled and rolled (I got quotes for doing this a year or so ago, and I think it I'd wanted five, it knocked about 20% off the costs of the raw components, probably similar off the "ready to fit" completed smokeboxes).

    Same potentially goes for other things - e.g. we've supplied bunkers in the past, and have drawn a full cad model of the tank (I know quite a few are running round with quite ropey tanks).

    Maybe there is no mileage in it, but as a concept it's got to be worth a try - potentially everyone's a winner if some sort of deal can be done that gets costs down, and thus locos overhauled more cheaply.

    Well, with that lot, there's not much left to make. Middleton' s got the patterns for the wheels so how much for a new Austerity (0-6-0ST version!):)

  3. ... and you're suggesting building a new one?

    I suspect we'll be seeing http://www.engine61662appeal.co.uk/project.html in steam on the South Bedfordshire Railway before that idea takes off...

    No he didn't. I did. However, please note the smiley.
    Then again, it might not be a bad idea after all. ;)

    Out of interest I will love to se some pictures of these cracks and wonder if it will be very difficult to have a redesigned backplate certified.
    I am not in a position to by one but wonder if it can be made better to day?

    Basically they usually crack up the waterside along the outer row of stays each side, alongside the corner radius. The throatplates tend to do the same. It's a very common area to find cracks on many designs, as it is a stress line that's very hard to design out. Quite a few other designs crack in the corner radius itself instead, which isn't really any better.

    I think the cracks develop fairly early in the working life of an Austerity backhead - I've seen several which show evidence of the cracking having developed, then been welded up when they've had a firebox replaced in their working life, and which have subsequently cracked again alongside the welds.
     
  9. No, I quoted the right person because my response was directly below Steve's, so I thought it was obvious who I was replying to... in response to his reference to the previous poster's comment, which was the one I quoted.

    Maybe is Steve was making a 'joke' it should also have been clearer?

    You quoted estwdjhn, but your statement was about Steve's post. If you are commenting on Steve's post, then please quote Steve!

    I really don't think it could have been any clearer! The smiley is understood by most people to indicate a joke or that the post should not be taken seriously.

    Well for what its worth i think this thread is spot on.
    its what the forum should be about, there should be lots of info here informing where you get things made and services available,
    the recent thread on firebars was excellent and these types of threads should be commended and encouraged.
    i know that some information is out there but it take some finding at times.
    i think there should be a suppliers section on the site where people can put up what they do and others can recommend or give an alternative supplier.
    anything that saves time and money as well as informing is to be appreciated.
    and it is, by me at least.

    And actually I don't see why a startup or a smaller railway wouldn't consider a brand new Austerity. For those kinds of lines it would be a darn site more useful than a brand new Clan (or Patriot. or P2...)

    You can buy a running Austerity in decent nick for about a third to half of what one would cost to build, so it would be rather a pointless activity!

    Did you see the price that was being asked for the one that John Bunch bought? I think you could have built an Austerity for that!

    Newtons of Cromford are listed above. The business relocated from Bradford some years ago.
