Hi Tony,
Looks very nice.

Upload the video to YouTube, then copy and paste the link into a new post. Simples. ;)
Cheers,
Peter

Very nice model and I look forward to viewing a video. The thing that really caught my eye though was the LMS 'Crab' in the background.....Well it would! Any images of this model?

There has been a gap in the market for a long time, so this is the first O1 kit to be produced. Like it's O4/8 sister they are unglamorous freight engines and I never thought a kit would be available for either. Well, it's still not for the O4/8, but Allen Hammett built me one a couple of years ago combining an O4/7 kit and parts from a DMR B1 kit. Considering that they were rebuilds, I think that the O1 is a pretty good looking loco. We are in a lucky position of having a kit for one.

Allen's O4/8, I need to play with that weathering a little more.

Just for completeness here is the O4/7 that Allen also built for me. 63770 was one of the last survivors around the Nottingham area and was well photographed and was considerably more shabby than my weathering portrays. I've not plucked up courage to weather the rather too clean cab!

So this will join my fleet of 2-8-0s...

Frames etches:-

Initial frame assembly, I'm using Slaters hornblocks. Laminated springs, they are a bit of a pain, but not so bad with some careful work.
P1050389.JPG
It's nice to get the laminated rods out of the way at an early stage, and they are used to set the axle spacings on the Hobby Horse chassis jig. I've lost one of my strong springs to hold the hornblocks in place so I have to do them in stages! I must save up for another spring...

The 04 spawned some interesting variants and I saw a good few of them passing Newton as well as Godley Junction before DC. Some looked more impressive than others. I was only in my early teens at the time, but with the benefit of hindsight, I suspect the impressive ones were the 04/7's. The two weathered models look great.

Hi Tony,

As you know I'm a massive fan of the GCR 8K and it's later LNER variations. Really looking forward to seeing the )1 progress. Looks good so far:thumbs:

Thanks Mick - Dave Wellington and I can muster between us pairs of O4/7, O4/8 and O1 as well as 5 WDs between us - now that would be a shed scene!

There are some tidy castings that make up the cylinders. The covers come over wide and the instructions advise to trim afterwards. I prefer to cut them as close to the right size as possible. That ensures that the cylinders are actually the right size. Getting the slide bars in the right position took a little patience. I put in the glands first, then used the piston rod to ensure the made up assembly put the slidebars in the right position. - the hole to locate them is... generous. I'll put on the drain cock linkage once I see how the assembly fits to the running plate.

Lovely piece of work Tony.

With cylinders, I sometimes use this simple "jig" to line them up and hold them square for soldering. A screw of suitable gauge for the holes in the front and rear plates, longer than the depth of the cylinders. Washers and nuts are then added and adjusted until it's all square, then tightened up. Bob's your uncle. It is particularly useful where the front and rear plates are separate and you are meant to add a wrapper to each side, and get it square. No chance! I think I first used it on the Scorpio large Prairie. Not a bad kit and it makes a nice model if you put the effort in, but the design is "so last century".
Cheers,
Peter

Tony,
Those are the David Andrew's Stanier 2 6 4 cylinders, so bear it in mind when you get to that. I trust you will write up the build on here, as I would love to see your take on it.
Cheers,
Peter

I'm on to the body now, and there is something quite therapeutic about pressing out all those rivets, I use the GW model tool. The windows surrounds should be a bit more rounded, but I couldn't think of a way of doing it neatly. There is an etch for the cab edge beading, but I replaced that with half round brass wire.
P1050402.JPG

I made sure I had a stock of these when I heard that HobbyHorse was going to stop trading. Enough for my remaining kits in the cupboard...

Assembling the cab on to the running plate. To start with, I just tacked the cab parts into position, checking for
square in all directions, and I did take them off again a couple of times before committing to seam solder the joints.
P1050410.JPG

My rollers struggled ( well me really ) with the boiler - it was quite springy and I couldn't get the middle to come in. So I had to resort to various bars as well as brute force! The instructions say to anneal the lower edge for the firebox, which I did. I think it would have been impossible otherwise, although I generally prefer to form without annealing if possible. I marked a line at the centre of the reverse curve for the firebox to give an idea where the bending bar should go..
P1050411.JPG

It was a bit of a fight and in the end I resorted to all my bending tools, from top to bottom, skirting board ( to pull out the lower firebox edge for starters- originally made for putting the tumblehome in 4mm coach sides ), aluminium bar, for applying pressure, laser printer roller - used inside the boiler to pull in the bits that weren't round enough, more skirting board - convex curves are pressed in to the convex depression using, the ex printer silver steel bar, and finally the home made folding bars... What didn't help was that it seemed the front firebox former is too narrow by about 4mm. That confused me for a bit!

It's not perfect, but boiler bands and handrail knobs added. I try and do as much work on the boiler as I can before it goes on to the running plate and cab.
P1050420.JPG

The running plate assembles nicely up on a cradle.
P1050417.JPG
Once the boiler is permanently attached to the running plate, the cradle is cut away with a slitting disk. Plonked on the frames, it starts to look like an O1. I'm enjoying building an LNER engine at last...

Hi Tony,
Very nice.

It looks like the boiler could quite easily be made detachable via screws through the saddle and cab, but for an all black unlined loco, I guess that doesn't bring much to the party in terms of easing the painting.

Cheers,
Peter
