On return from holiday at the end of August I decided to start a new project that has been in the planning for a while now. Having completed the ex-Ashover coach in LCLR condition and with a micro-diorama in mind, I needed a typical LCLR locomotive to stand with it. Having done some research into the various options I had settled on no.4 'Wilton' in it's Humberston condition. It still had the original bodywork when I visited the LCLR at Winthorpe in 2013 but has since been rebodied in a different style.
Having looked into various options on Shapeways for an 009 3D print Simplex chassis I eventually opted to scratchbuild the whole model, but incorporating the 3D printed buffer/couplings designed by David Malton that I had purchased some time ago. Building the model in this way allowed me to incorporate most of the bonnet into the chassis, giving the opportunity to add strength. Construction started in 30 thou styrene on the 30th August.

The cab was added from 30 thou styrene and 10 thou material overlaid on the bonnet sides to create the effect of the side sheeting overlapping the chassis frame. Surplus brass from A1 Models kit frets was used for the bonnet top and (presently removable) cab roof to gain strength in thin material. Details were built up using styrene rod for rivet heads, the exhaust and grease points on the axleboxes. The grille material on the front is from an ancient piece out of an MTK kit, inelegant but so is the prototype... The buffer/couplings were fixed in place and the plate around the bottom added from brass strip.
Underneath the model there is a little bit of cheating going on. It is of course a dummy loco and rides on two Farish wheelsets. These are held in brass 'U' shapes drilled to hold the pin points, then attached to a length of styrene girder. Further bits of brass add strength either side. The axleboxes were fabricated from 20 thou styrene strip (20x80 and 20x20) and shaped once set to the distinctive Simplex shape.
Just as I thought the model would be ready for the paintshop, something was bugging me about it. I'd mostly worked from indistinct images, downloaded and printed on copier paper. I was not convinced that I had the boltheads on the frame in the right places (or enough of them) and looking at pictures of the loco as rebodied eventually confirmed this. Why I hadn't done this previously I've no idea... Going to add them I realised that the scrap of 20 thou styrene rod I had been using had been used up... This led to an order with 7mm Narrow Gauge Association Supplies being made on Sunday morning, arriving on Wednesday this week.
I was then able to correct the bolt head detailing and then spray the model in primer.
I also realised that I had not added a cab door handle, and that perhaps the bonnet top needed a representation of hinges...
There are a few tidying jobs to do but I'm pretty happy with the result, hopefully it won't be long before the blue paint is required...
