The main frames are were we begin properly on the engine itself and I have to say that Don's drawings are more or less a true scale miniature of the original prototype, they are an art-form in their own right. This is the first part, like the

On to the bogie spring set-up, again, lots more work involved here and unlike any of the other suspension components on a Gresley Pacific, these are helical springs rather than the leafs springs on all other axles. There was one exception of the class to this rule, 1470 Great
Flying Scotsman
Ah the axleboxes, I have to admit to really enjoying making these things, a hell of a lot of work when talking 'split boxes' but well worth the extra effort involved and of course, they follow full size practice. I posted this picture just to make a point

I was very much looking forward to doing these wheels, things begin to take shape when sitting on their wheels, even it is only those for the front bogie. There's a fair bit of work in machining wheels and not just in the machining, the spokes also need
Flying Scotsman
Continuing the build on the bogie I moved onto the yoke, overall dimensions are 2 3/8 x 1 5/8 with the spigot being 1" wide to fit the slot in the bogie centre of which I'm happy to report it's a nice sliding
Flying Scotsman
There's a lot of work in this part, not such in machining the casting itself, but in making all the spring control parts that fit within it. I have tried to collect the relevant sections and put them together. I may well have missed a few bits as
Flying Scotsman
So where to start?, well I thought I'd start with an easy item, the bogie truck, did I say easy??? I had read Don's "words and music" completely a number of times by now and in fact, many times since, most of which is

This is a big update, this will be where I leave the tender for now until the final painting session once the loco is ready for the same. There's a lot of parts covered in today's update, plenty of extra detail and lots of painting, some
Flying Scotsman
This update is going to look a bit strange as some bits may look 'out of step' for example I begin covering the fabrication of the steps and then the water piping, you'll notice in the last picture for the water piping that the steps are

Brake cylinder support brackets, I've deviated from Don again ( making a habit of that) both in method and design. Don states to bend up the brackets from 1"x 1/16 steel, drill 1/4 hole for bearing which is turned to suit the fulcrum pieces ( next)

Dons 'Doncaster' has 4 cylinders , 2 each for the loco and tender. these are vacuum controlled and incorporate an auto-braking system. This again is as per prototype. I have tried to cover the fabricating of these cylinders in as much detail as possible whilst keeping it simple,
Flying Scotsman
The vacuum brake reservoir stores enough vacuum to enable the brakes to operate, the brakes on this locomotive are the auto-brake system, that is, if the locomotive becomes separated from the tender the brakes are automatically applied. The reservoir tank is a simple thing to build, I have deviated
