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 to use for a datum? As these are important for the motion I decided to first tidy up what I&

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 post earlier. This is the result of John Baguley's CAD work, truly superb for accuracy to the drawings.

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 is the last stay to be made that fits between the frames, this being the rear stay that

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 differences which I shall cover. First off I cut all the springs to length, as with the tender

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 different approach just to speed things up a little. I don't have pictures for all the

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 solutions for the rear trailing wheel. The principle being that the axleboxes are angled and swing as one in an

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 machine to size including the recessed lip for the door ring but leaving oversize on the stock tube

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 on looking at it this morning it only covered the fitting of the buffer housings, I'll do that

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 to have cut them all out by hand I wouldn't be as far into the build

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 casting so that they could then be turned over and held flat on the mill bed,

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 relevant holes so that the screws sat correctly within them, fixed rivets into the temporary holes that had

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 I used with a small modification to form the curves, more on that later. I'll begin
