I have now cut the axle keyways and as long as they are correct ( pretty confident of this) then I guess you could say that that's the quartering taken care

So...Coupled Wheels NB: I will state from the beginning that I had a 'whoops' moment with these, soon corrected, never say die is my way of living..:) more details

Main axleboxes continued, on to the important bit, well their all important but for this stage I have tried to be extra careful, after plotting the right hand side crank

Onto the axleboxes, Don has followed full size very closely without going to far overboard, such as no machined pattern on the slot faces or some of the smaller parts.

At this point I decided to do the name plates, I'd got used to seeing it in the reference photo's while working on the running boards so perhaps it's a

Ok so the 'Smokebox ring' , I'm lucky as my son had given me a few off cuts from his work, two of which were perfect for the smokebox ring so

The outside motion brackets are tricky little buggers, first the castings are not identical, they have many surfaces to keep an eye on for size and also on deciding what

Before making a start on describing the construction of the expansion link bracket  which deserves to be explained in detail. I best start with this picture which I forgot to

There are a few bits and pieces that I'll include here just to tie up any lose ends around the frames before moving on to something more substantial. First up

Springs are the topic for this entry, I haven't taken pictures for all the construction as some of it was just a repeat of the tender springs, but there are

trailing wheels.. Now I've used a number of methods in the past for turning up wheels, listed previously with the tender and bogie wheels, this time I took a slightly

The Cartazzi (some say Cortazzi) trailing wheel system is one of those things that, for me  was a delight to make and also unusual when compared to most other locomotive

I am so glad that i approached M-Machine-Metals for the material for the smokebox. During discussing the size needed with the metal company we decided between us that they would

NB: I had thought that I would be giving more detail on the buffer beam at this point as it was the next item to show in my log but

MB: This part is where I really did appreciate the wonders of modern technology with laser cutting. It didn't take too long to fabricate the following parts, If I had

Horns There's a lot of work involved with 4472's Horns so this will be a  larger entry than normal. First job was to file flat the top edge of each

First a few notes on what I'd been up to prior to this latest entry, treat it as what happened behind closed doors.I split the frames and countersunk the

This entry has some involved parts, the buffer housings for one although life was made much easier thanks to Malcolm's laser cut parts, he also drew up a guide which

Most of the parts seen in the next few entries will be laser cut parts as supplied by Malcolm High of Model Engineers Laser.  these will begin with CAD work

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

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

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

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

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

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
