Next up the underframe/sill. As the instructions indicate label the solebar ends A and D (LT style) as they are not the same due to different holes in etched in the ends for the pipework.
The instructions suggest installing the solebars first and after some measuring I found it easier to solder one buffer beam to the underframe first.
I clipped the buffer beam to an inverted razor saw mitre box with some cereal box card behind to lift rivets from the box and provide an end stop for the underframe. The underframe was laid on a block of wood and then butted up to end stop. The buffer beam was adjusted until it rested on the underframe. Once satisfied everything was nice an central solder was applied
The solebars fit outside the body mounting slots in the underframe and to assist installation I cut some card to fit into these slots.
The solebar was clipped to the card and then moved up to the previously installed buffer beam. This was then tack soldered, a check to make sure it was vertical and then soldered into position. The single buffer beam also provides a guide to assist in keeping the solebar straight as there are no guides.
The other buffer beam was soldered into position followed by the second solebar. Again this was clipped to the card supports in the slots and hey presto! one underframe.
The cabs - built as per the instructions. Although ready formed some tweaking was required. To assist soldering the cab around the cab base I fixed the base to a block of wood with drawing pins to prevent it moving. The window frames were made up in accordance with the instructions.
And...... all looking good so far as nothing has had to be fiddled, fettled or faffed with to get it to fit.

Thanks for the insight JB. I'll have to keep an eye on these and at least it's an easy job to replace them

Watching this with interest. I've one in the pile and this might make me bring it to the top!

Been sitting in a coooool house (1840's with 2' thick solid stone walls built partially into a hillside) doing some more on the Bo-Bo.
As I require functioning headlights I drilled out the cast whitemetal ones with a 3mm drill and inserted some 3mm o/d 2mm i/d copper tube to accommodate 2mm tower LEDs.
Tube soldered into light housing - here ready for trimming.
A washer was used as a cutting guide and the excess cut flush with the washer using a piercing saw.
After trimming I used a countersink to clean the end. The light housing was cut off the tube and the process repeated for the five remaining lights.
I also temporarily fitted the truck mounts to check the ride height and thoughtfully washers are supplied in the kit for this purpose. In the end one was required at the D (driving ) end of the loco.
With roof plonked on -
The destination brackets were also folded up and installed - following the instructions as they are handed. And there is also an error in this photo.
The schoolboy error - the A end cab is sitting on the D end. Although the cabs look identical there is one very subtle difference between the A and D ends........
The destination boards will be resized in due course - so far I have Aylesbury, Baker Street , Chesham, Moorgate St, and Verney Junction. Missing are Harrow, Liverpool St, Rickmansworth, Uxbridge, Watford, Wembley Park and a host of others.

Hi John
Only in my marker pen as instructed otherwise they are not. However, Ken includes a line drawing indicating which ends of the footplate to mark up as A and D and it's also made clear in the instructions you should use a marker pen to mark up the relevant ends. The A end of the solebars are indicated on the fret.
There is also an indication on one of the inner corners of the cabs as to which is the A and D end but I found out after re-reading the instructions. It was just a case of revisiting the construction photos which accompany the instructions to identify the cab ends and duly scrawling on them with a trusty marker pen.
I know LT cars have A and D ends but didn't realise it also applied to the Met Bo-Bo....
. I have known better.

It may come to the top quicker than you think....
.This for me so far has been a nice kit to build - all straight sides and flat pieces. Made even better as the cab is already formed and there are no other curvy or tubular bits to faff over.
It's just a case of following the instructions and I've only made some modifications to suit my own requirements namely: the Canon motor; Slaters wheels for all round insulation and illuminated headlights. Another modification has already been earmarked in respect of the body mounting.

Little more progress...
Adding the handrails to cabs.
Here are the two cabs side by side with the difference between the A end and D end.
To ensure the cabs are at the correct end of the footplate I temporarily bolted the A end cab to the A end of the footplate and drilled a 0.8 mm hole. The hole in the footplate was opened out to 1 mm and a piece of 0.8 mm rod soldered into 0.8 mm hole in the base of the cab. This forms a locating pin to make sure the body will only fit one way onto the footplate.
Silly me - I've been using metric measurements and the wrong words if today's Times article is anything to go by. You would be forgiven if you thought it was 1st April but it's all summed up in the first sentence... Jacob Rees-Mogg spells out banned words to staff
Gilbert and Sullivan springs to mind -
I am the very model of a modern 19th century politician
I've information vegetable, animal, and mineral
I know the kings of England, and I quote the fights historical
From Marathon to Waterloo, in order categorical
A s for me I'd better start using rods, roods, poles and perches.

On the other hand......
We've become sloppy in our use of the English language because we've been taught that "it doesn't matter as long as you are understood" - (should be ".....one is understood.") Words in common use do not reflect their actual or original meaning, probably one of the best examples is "got" which an English teacher taught me years ago is unnecessary in any sentence as the actual meaning is associated, let's say in mixed company, with procreation.
As for using imperial units of measurement I have to agree that is the road to madness, although the Americans appear to be satisfied with their own units. In the past that has also lead to some interesting errors in conversion, though and the USA is a hugely bigger market than little old UK.
In any event, to excuse the vernacular, he's pissing in the wind.

As an apprentice Chippy, and at school before, I was taught both imperial and metric and how to convert it from one to another. I can remember helping my Father convert measurements when he had to start measuring stuff in metric because the architects drawings had started to be drawn in metric, apprentice showing Master 
we did have some laughs at that, but he soon got his head round it.
The building trade is good at confusion of standards, or should I say lack of standardisation.
Sawn timber seems to now be cut in metric lengths, 4.8m instead of 16'-0"( 4880mm) etc , boards or sheet material is still imperial, an 8x4 sheet of ply being marketed as 2440mm by 1220mm. why ?
When I built my workshop I set it out to use whole sheets of ply, 8x4 inside, set the studwork and floor joists out for imperial centres, but the bloody flooring came in as metric sheets 2.4 x 0.6
so had to make adjustments to the floor joists.

We glider pilots in the UK seem to be as perverse.
We talk about height in feet, speed in knots, distances in kilometres, achieved cross country speeds in kph and climb rates in knots (or hundreds of feet per minute, much the same).
My on board computer system is programmed for it!

As for misuse of the English language (and appalling spelling), of my pet hates is the construct "Me and my mate went down the pub"
And the confusion between "loose" and "lose"
Having been accused of being a pedant yesterday, it's probably not a good idea to get me started.

.....and the motion picture industry is as bad...... Film is 8, 16, 35, 65 or 70mm wide (plus defunct sizes like 9.5mm and 17.5mm) with perforations normally quoted in imperial and lengths of 50, 100, 400, 1000, 4000 or 6000 ft.
Time we aplogised for hijacking Dave's thread and returned to the subject in hand, although Dave started it himself so ya boo sucks.

As an old biker and getting older the only time the word loose was mixed up was when we had loose bikes and fast women
...or was it fast bikes and loose.....
