Combined Stretcher / Spring Hanger Bracket
  We are delighted to report that the second combined stretcher / spring hanger bracket has been ordered from Norton Cast Products in Sheffield. This combined stretcher is twice the size of the first with 4 'legs' rather than the 2 on the previous casting. All in this casting will weight over 500kg.

This represents the first time one of these stretchers has been cast since the 1950s when 71000 'Duke of Gloucester' had her stretchers cast.

It is expected that this stretcher will be cast in 6 to 8 weeks.
Horn Guides
  The new horn guides have now been ordered! 6 are being cast at Norton Cast Products in Sheffield out of grade A4 steel. These will then be delivered to Stephenson engineering to coincide with the completion of the frame plates to be welded into place.

The horn guides also have the stop bosses and lubrication ports included in the casting. The risers formed as part of the casting process will be left in tact (along with some cross webbing) to strengthen the castings during welding and minimise warping during cooling.
Progress Report
  A quieter week this week with three casting jobs waiting to be poured at Norton Cast products :

Combined frame stretcher / spring hangar number 2 (between the leading and intermediate driving wheel sets)

Rear Combined stretcher / brake support stretcher

6 off horn guides

The horn guides are critical path as they are required before the frame cutting process can begin to ensure the cutting and machining can be completed as one job.

The pieces that will be used to create the pattern for the third (and last!) combined frame stretcher nears completion, look out for a separate article next week about the pattern making progress.

As previously mentioned the working parties will commence on Saturday 7th September. All members are welcome and members of the Engineering Committee and Council of Management will be present. The first working parties will concentrate on sorting the racks of components we have in stock along with repainting the cab structure.

As with all projects of this size the donations govern how quickly we can build the locomotive. There are several ways people can help:

Join the project and have access to the locomotive as it's built and when it's running on the mainline and preserved railways. Members also have exclusive access for major events such as the frames reveal scheduled for next year.
By using the easyfundraising service below. Over 2000 retailers will make donations to the project, at no cost to yourself, when you purchase form them online using
By making a donation or series of donations using the 'Make a Donation' section on the front page of the website.
By donating or purchasing items from the sales stand at events or via our website. One off items such as the limited edition A1 Tornado Bachmann model appear exclusively on the website. These items are donated and all funds raised go to the locomotive.
By joining us on the sales stall at one of the railway galas. This isn't as much work as it sounds and it is a great social event and you're not chained to the stall so feel free to take a ride on one of the trains and look around!
