Project Coronation – Tender part 2
The tender chassis is now effectively done – Not a lot else to say really so here’s some pictures.

Project Coronation – loco chassis, part 2
So progress continues on my Coronation build.
The front frame is as far as I can go for the moment. (I don’t have the cast bits for the loco yet. If you are wondering about the cylinders they are a separate sub assembly.
No problems with the pony truck so far. The kit provides for both the earlier and later types. This is the later one.
The bogie is compensated. As the bogie is the only part of the loco that traps the wheels in place I have used some old/rejected wagon wheels for the moment. I ideally only want to put wheels onto the axle once if I can.
Without the wheels in the way.
I couldn’t resist a temporary mock up to see get a better feel for the loco. I’ve used a High Level Road runner + gearbox. The main drivers don’t have their springs in place yet so its sitting a little off at the moment.
Project Coronation – loco chassis, part 1
I am currently embarked on building a test build of the forthcoming Brassmasters Coronation or Duchess kit. Way before I got distracted with Brettell Road I always thought that if Brassmasters ever did a Duchess i would have a go at building one as 46235 ‘City of Birmingham’. Well now they are and so I am!
Of course its a personal opinion thing but I never really liked streamlined steam locos. While the Duchesses were a little more thoughtfully designed than the god awful GWR efforts I always thought they looked a bit like an upturned bath tub and have to admit the A4’s did look a fair bit better. However with the streamlining taken off the Duchesses were ‘it’. The steam locomotive version of the Concorde moment. To my eyes, at least, the pinnacle of steam loco perfection.
Anyway enough hero worship and on to the model. Starting with…
The main sub-frames. The loco frames come in 3 sub sections related to the wheels. A driving wheel section, a pony truck section and a bogie section.
The chassis upside down, test fitting the main coupling rods.
The main frame with the brass overlays fitted.
The front or bogie area sub-frame.
More to follow.
J94 Project – Done!
When I picked up my nearly finished J94 kit it came with an already assembled Branchlines Gearbox. Try as I might I just couldn’t get on with it. For some reason it seemed to have very little torque but this wasn’t sacrificed for speed as it didn’t really have much of that either (perhaps the energy was being used up by the noise it generated?). So admitting defeat I swapped it for a High Level Road Runner +. What a difference that made!
Another little problem I came across was the lack of space between the inside motion and the springs I fitted on the front 2 axles. I had used a short handrail knob in the same way that the advocates of CSB systems use but it was all just a little bit too tight for comfort. So I ditched that and just soldered a couple of springs to the inside of the chassis – Number 10 guitar springs for the center axle and number 12 for the front bearing on the top of the axles. Anyone with any kind of knowledge of how things should be done are probably reading the rest of this post from behind a sofa but it works so that’s fine in my eyes!
Anyway its done so here’s a few pictures.
Here’s a very short video of the inside motion at work
Below are a few evening images.
Another little video – this time a spot of shunting. There’s a few stutters which I am hoping a little more running in will iron out.
Finally one of those unplanned shots you sometimes get when you are focussing on something else and they just catch your eye. A simple line up of coal wagons.
J94 project – something a little different.
Several years ago now DJ models appeared with much fanfare (Although only in one place if we are being completely honest) and announced a brand new J94 model. This was of interest to me as 2 of them were used by the NCB in the local area. While it would have been a nice to have I was never going to go for the RTR effort but i did hope that if it was good enough it might see a few unstarted Brassmasters kits appear which would be a little more up my street.
In the end this didn’t really happen so the idea was kind of abandoned until the good folk at Brassmasters mentioned they had a unfinished test build of their kit somewhere. Money changed hands and a slightly different style of project was formed to what I’ve done in the past.
So this is what i was presented with (albeit with a Giesel chimney that i replaces with a RT models casting) and a little box of spare parts. I’ve never finished a half started loco kit before and with no instructions and not knowing what bits I didn’t have it was going to be a bit of an adventure.
The easy route would be to just add the body detailing and finished what I had but the chassis was missing most of its representation of valve gear and I didn’t have any of these bits in my little box of spares.
The chassis as supplied.
My friend Les supplied me with a copy of the original instructions (which sort of helped a little) and members of the Scalefour Society forum kindly provided pictures of the etches, some finished models and some prototype pictures so I set to work.
The detailed up body, using prototype pictures as a guide.
The Chassis. I used a Brassmasters inside motion kit, shortened by 3mm and simplified. The prototype locos seeming to have a much more rudimentary arrangement than the LMS locos the Brassmasters kit is intended for. I also couldn’t use the original central pivoted rocking beam compensation so I have sprung the front two axles from a central pivot on either side instead.
21st July 2011
I have always liked the MJT torsion bogie and (given that I need so many) decided to etch my own, incorporating a few changes to make building them quicker. In the end the center wire was replaced with 2 pins and these merely hold it all together and dont use any form or torsion control at all. The control now comes from the cross wires between the brake shoes.
These bogies are now available from Brassmasters,click here for more information.
