Merrie Carlisle, more progress

LMS 5050, Merrie Carlisle

When we observe a real steam engine the viewpoint is usually low, however in the case of a model it's quite different, we view the model from above and one of the first things we notice is the space under the boiler between the frames where the inside motion sits and a Precedent displays her inside motion quite prominently. At the moment Merrie Carlisle has no inside motion, a very noticeable omission which needs to be remedied. I'm working on it and if I can make the motion work then I will, if not then it'll have to be simply cosmetic motion, non-working that is, either way it'll fill the gap.


The crew's working space...

I'm working on the loco crew now, they need to be designed so they don't both stand in the cab which is a very restricted area and even more so since the splashers are closer together than on the real engine, it's tighter by about a scale 5 or 6 inches, so watch this space...


The cab and backhead in detail.

The pale green floor area is Milliput into which a brass fret had been pressed to simulate the small wooden blocks that formed the lower cab floor on these engines, it'll work better when it's glued down and painted. There are two wooden inserts in the upper cab floor which have been made out of planking from a model ship kit. Most of the backhead detail owes something to castings from LGM. I think I've included everything you can see on the real thing though I never found room for the blower handle which I think was in the right hand corner somewhere.

LMS 5050 Merrie Carlisle progressing

The triangular ash hopper has a shield to prevent ash blowing up into the motion, the hole in it is not prototypical, it is for access to the body fixing screw.

The cylinder drain cocks can be seen below the front cylinder covers, their operating rods have been modelled as far as possible. The join between the working frames and the wider forward extension of the frames, which are fixed to the footplate, is clearly seen though is not obvious when the wheels are in place. The gap between the front and rear plates of both the buffer beam and the ash hopper are filled with Milliput. The void in the buffer beam allows the front coupling, which is pegged in place,  to be removed; these are fully working couplings supplied as a kit by CPL Products, the characteristic LNWR "T" bar is an added refinement. Note the front sand box nestling behind its outer cover, the lower part of the sand pipe is yet to be fitted.





Work on the detail in the cab is at an advanced stage.

 
The roof is soldered to the inner spectacle plate, both this assembly and the backhead can be removed so I can work on the detail, some of which you can see in this view of the engine. The lower footplate of the real engine consisted of a casting which accommodated wooden blocks a fraction over 1" square. I've not modelled this feature yet as I need some Scale Link 1mm square mesh which is proving difficult to come by. The idea is to push the mesh onto a flat piece of Milliput which, hopefully, will pop up through the mesh to form the "wooden" blocks!



Cab details progressing though there's still more to add.

 
Most of the castings used in the cab are from Laurie Griffin Miniatures and though they have all been modified in some way without them this sort of detail would not be possible.



Superstructure and frames pose on the wooden block that the engine is built on surrounded by the debris of a working session in the studio.



I bought some collarless handrail knobs from 62C Models which hold the handrail that runs along the larger vacuum ejector pipe on both sides of the engine. On the right hand side the hand rail operates the blower valve which is attached to the smokebox, this was done by turning a handle in the cab which I have not yet managed to model. Behind the chimney sits the smokebox regulator lubricator for which I have not been able to locate a suitable casting so I'll have to make one myself. The LNWR Society's re-publication of Bill Finch's book on building an LNWR Jumbo is invaluable and provides drawings of most of the details I've included in the model or have yet to make, Jack Nelson's book "LNWR Portrayed" is also useful to modelers
