Tin the inside of the slots on the front piece, add the rear piece first, then the wood and then with a hot iron zap the front piece from the front, it should solder to the frame tabs and hold it all in place.

...the wooden 'filling' was glued (epoxy, ta) to the outer buffer beam after the buffers had been fitted (modified LGM castings.) [The buffer stocks have had a small collar soldered to the ends to improve appearance and the locating tube removed from the rear. The buffer heads are held in place by soldering a small washer to the stem and trimmed as appropriate. the buffer movement is contained in the wooden portion of the buffer beam.]

Final assembly of the rear beams was done on the chassis. The inner beam was soldered to the end of the chassis, checking for squareness in all planes. The outer assembly was glued into place, again checking alignment very carefully (I used a 1.7mm drill through the coupling hole to help.) The wooden portion had a notch cut in the top to allow access to the locating tab with a soldering iron tip. Soldering adds much more strength to the sandwich. Angle iron strengtheners, as prototype were, added. The designer had kindly added etchings for the triangular gussetts (hero,) also added.

The slots in the front buffer beam etchings are in the wrong place. The frames are wider at the front of the loco than the rear and the slots are to suit the rear only. It's an easy fix though. I had to make some locating tabs like this, from material the thickness of the chassis plate;

and assembled the front buffer beams by soldering the locating tabs to the rear beam and glueing and soldering the front assembly in place. I added a strip to disguise the locating tab as the angle iron strengtheners thus;

The slots are in the wrong place by a distance equal to the thickness of the chassis plate (x2) so the front beam can be easily soldered in place now, again carefully checking alignment.

The coupling hook on the rear of the loco is very long, as when the loco was rebuilt the original drag box was used. This necessitated a very long hook to reach it. It was fun to build prototypically.

It'll be at Telford on the Modelling Competition/Sunday Display stand all weekend for inspection. See you there?.......

Possibly, but easy mistake to make. What happens when no test build. Easy to sort though.....

Many more good bits than mistakes.

......I've managed to fit up the footplate to my W or A6 chassis. It was easy as the footplate is a sub millimetre fit. Good design again. I suggest to anyone making one of these from my (and Mick's) parts to put the outer part of the buffers on the chassis AFTER fitting up the footplate. That way you won't have to realign any buffer beams later. They do fit perfectly but best to use the footplate as a jig. It is also very important to get the chassis perfectly straight and square. Also if you're adding all the cylinder head details you'll need to cut away sections of the footplate to accommodate them. Sorry about the poor pictures......

...a bit more progress today. I have made some brackets to fasten the chassis to the footplate (body) thus;

And will take some steps to disguise the screw head later (don't like screw heads on view!)

I then fitted up the valances to make a nice crisp chassis/footplate on which to build upwards.

Next the chassis sections above the footplate....

...so over the last few days I have sorted out the brake hangers which on a lot of NER locos seem to double up as the footplate support brackets. The ones on the etches are good but I have detailed them up a bit and and attached them to the chassis in the half etched locating holes. There are an additional two brackets on each side that are not on the etchings. Just draw round the brake hangers provided and cut them out. They're the same shape. Here's all fitted up.

Lovely work as always Nick. You're right about the brackets, from what I've seen they are all designed in a similar format, supporting the footplate and carrying thebrake hanger. Generally the front brake hanger is smaller and doesn't but the remaining two do. Although this is not exclusive. Great to see these details as most NER prototype kits just provide a simple fold up U shape bracket which is no where near correct,

I had to do something similar when I built my 4mm DJH Q7 a few years ago I was fortunate in that Arthur Kimber (NorthEastern Kits) send me a scale cad drawing of the part to work off.

....I have built the steps.

Although the front steps have backing plates on the etch, they aren't handed (oops!) It's and easy fix though filling the slots (I used old boiler band strip) and putting the treads on the rear.

These were then fitted up to the footplate and I have begun adding all the angle iron and strip that's present under the footplate to hold everything in place.

More to come as the work progresses.

I know but still annoying. I can see what I did, I rotated the part rather than flipping the part :rolleyes: School boy error :D

Ahahahaha!

Don't worry I'm sure captain cockup will be visiting my door shortly after I send the D16 etch off..

Although in theory, just needed to put the half etch on t'other side?

And that is exactly what I have just now done on the master etch work.

However, when I look up out of the stable door I find the horse is already halfway across the paddock :eek:

Nick,

Those internal cross shaped slide bars, do they come with the stuffing gland and cylinder rear bolted plate attached and can you remember the part name or number from Laurie? I've had a quick look at his list and they're not jumping out at me.

I need a single set and crosshead for a three cylinder project on the go at the moment please. I presume they come as singles but expect they'll be a pair, no problems if so as it's a three cylinder engine so the spare one can go on the second engine.

I also need three valve covers with stuffing glands but not quite the same shape as yours, they're a much simpler affair. Without pictures on Lauries bits for NER stuff I'm flying a bit blind.

Best

The slide bars come attached to the stuffing gland and the cylinder covers are separate items. I just bought his NER 4 bar slide bar Stephenson motion set, well 2 sets actually. I know he sells individual items as I've had them in the past. You'll probably have to ring him.

Good luck

Oooh pictures, I'd heard LG had done that but couldn't find them the other day just a text pdf. Will have a good ferkle around tonight:thumbs:
