The Shifting Sands loco fleet has had its first new acquisition in some time, a rebuild of the well known Knightwing 4mm scale industrial diesel kit, based on a Kato chassis.
But first, some background. My attempt with this kit for use in O9 was back in 2005, inspired by an 009 version seen in the 'Railway Modeller'. At that time I couldn't see a way of using the brilliantly moulded chassis sides in O9 as the wheelbase was too far out and they were too high. So I scratchbuilt a chassis frame around a Kato 4w chassis. I then encountered a problem, the loco was too short to effectivelly operate with Microtrains uncopling magnets, the magnets were strong enough to stall the motor slung between the axles! A massive rethink saw a new chassis frame built, and a short bonnet added the other side of the cab to use up the length. Being honest, this new chassis was never my greatest work and this has been a somewhat unloved loco ever since...
I moved on. The next loco off the workbench was the model of Kirklees' diesel 'Jay'. Building this, on the same chassis, resulted in some experimentation with the Knightwing chassis parts, which I cut-and-shut to fit the Kato wheelbase. This was achieved by cutting immediately in front of the cab steps and then in front of the rear axle spring hangers. Re-arranging the parts with some plasticard to replace the steps gave a 28mm wheelbase chassis, although at that stage a very long one. This was eventually used under the rebuild of the former 'Yellow Perril' as SMR no. 3.
As an aside, illustrated are a novel use of Knightwing axlebox covers, cut out and shaped they feature on my 1/24th scale Lister RM3... This set we spare from a 4mm scale conversion made years ago.
So on to 2008, the latest Knightwing conversion was an attempt to use as much of the kit as I could to make what is effictively an enlarged version of 'Jay'. Perhaps more suited to somewhere like Perrygrove or the Bure Valley than a seaside line, it has proved a very effective conversion. Hopefully the pictures will show the work involved without too much explanation. |

Back to 2005, my first O9 Knightwing conversion underway. |
As completed the loco looked very different after a change of plan. |
The increased length was matched with a scratchbuilt 'short' bonnet. |
First experiment rebuilding Knightwing sideframes to fit the 28mm w/b Kato chassis. |
The same chassis as used under SMR no.3, albeit shortened a little. |
Adapted Knightwing axleboxes used on my 1/24th Lister project. |

Cab end view showing the dropped door bottom, awaiting a dropped footplate. |
A week or so later all sorts of little details are in place, air pipes are from Replica Railways... |
headlights are from the kit, whilst air horns are from A1 Models. |
The windscreen wipers and door handles are from brass wire shaped and blackened. |
Before paiting the headlights were repositioned ahead of the bonnet rather than either side. |

Colours are Humbrol Brunswick and Lime greens, the latter from a genuine 'old' Hull produced tin! |
Test running with passenger stock, Cumbria just sneaking into the frame. |
Headlights are created by painting the inside silver and using a blob of Araldite to form the 'lens'. |
Test running was keenly observed by Mr Sooty, chief loco-catcher... |
