Boiler
The drawings for the boiler were not part of my original work program as it was expected that the boilermaker would be able to work from the comprehensive design layout created by Ian Gaylor. In the event the price quoted for the boiler included a significant price for the creation of the drawing(s) required for approval by the insurance company, the detail drawings for the components and the positioning of the stays. In order to make it possible to get the order placed I took on the detailing of the boiler as part of my work program and this is now complete. The boiler has been stress relieved and the tubes and stays are in place.
09/11/2013: The steam dome has been split to make assembly of the regulator easier. this should make future maintenance easier.
28/04/2014: The boiler is finished and ready to fit to the loco.

Superheater
The drawing set for the superheater is complete and the process of making it has started with the sourcing of the superheater tube return castings. I am expecting to have to make some adjustments to the drawings as the manufacture gets underway and the boilermaker gets to grips with welding the assembly. I have now redesigned the superheater to make the manufacturing easier. This is complete and issued for manufacture.
09/11/2013: welding of the superheater is now complete, the chambers have been stress relieved and are now being machined.
28/04/2014: The Superheater is finished and fitted to the boiler.

Smokebox
The main part of the smokebox is made as part of the boiler manufacture. All of the drawings have been completed but the cutouts and bolt holes for the fitting of the chimney and the mounting to the saddle can't be done until later in the assembly process when the assemblies are brought together.
28/04/2014: The smokebox is complete and welded to the boiler. The remaining holes will be added on assembly to the loco.

Cylinder
The drawings, CAD files and models for the cylinders are complete and issued for manufacture. Some of the parts have been made.

09/11/2013: Because of un-expectedly high manufacturing quotation I have been through the design and done some simplification. The drawings for this update are now issued.
28/04/2014: The cylinders are being made by Frosts of Norwich and are well advanced.
11/03/2015: the welding is complete and the cylinders have been stress relieved. Machining has started.
30/04/2015: Machining of the assemblies is finished and the liners are being produced.
26/06/2015: Machine of the main assembly is complete and the liners have been fitted. The last bits of machining and the pressure testing will be done soon.
14.10/2015: the Cylinders are fully assembled and the liners fitted. They have been sent to have the bores honed to final size and will then be complete.
The cylinders are finished and delivered to Keefs

Saddle
The drawings, CAD files and models for the saddle are complete and issued for manufacture. most of the parts are made and the welding of the main assembly is progressing.
09/11/2013: The manufacture is now complete except for a couple of small machining tasks.
28/04/2014: The saddle is finished and stored ready for assembly to the loco.

Regulator

Front and Rear pony trucks
Front and Rear pony trucks are modelled in rough form only and will require substantial design and modelling before any detailing is undertaken. The rear pony truck will require a different mounting method to accommodate the deeper firebox and the design details will need significant design input.
28/04/2014: The front pony truck design is in hand. Ian is doing the calculations and I have started the modelling.
17/02/2015: Both pony trucks are designed and modeled. The detailing is started and should be finished soon, probably after the frame drawing are completed.
