Maunsell 350hp Shunter Body Kit
 
by Graham R 'Muz' Muspratt

Broadside view of the model
 
This kit is designed to fit on a slightly modified Lima 09 class chassis. It could also be fitted to a much-modified Bachmann 08 chassis. A very basic single sided A5 instruction leaflet is supplied which gives details on fitting the Lima chassis and body assembly.

Kit, as supplied:

  • Cast resin one piece body
  • Cast resin lower cab rear
  • Cast white metal, Radiator grill, radiator top, bonnet top, buffers, front and rear steps
  • Flush glazing

Chassis modifications
The Lima chassis, that I chose to fit as I happened to have one to hand, simply requires slight modification involving cutting the top of the Lima lead weight, bending slightly one of the motor bush holders to give clearance and filing back very slightly the front of the chassis to give a snug fit. The Lima fixing lugs at the rear of the chassis are retained. It is also designed to keep the Lima body fixing screw although I chose to replace this with an 8BA screw and properly tapped the cast resin lug in the body rather than use the Lima screw to self tap this lug for fear of the thread easily stripping in the cast resin.

The whitemetal front steps were then fitted to the Chassis as per the instructions and handrails fitted from 0.5mm brass rod.

Body modifications:
The body required very little cleaning up but care must be taken around the window openings, especially the front windows.

Rear windows -
The body as supplied has only two upper windows on the rear of the cab (which is how the class appears on most available drawings) however it is apparent from photographs that very early on, if not when built, the class has two lower sloping windows which overlook the buffers and coupling hook. I drilled and then filed these two windows using photographs for reference to the exact location.

Lamp irons (Bambi staples) and the pipe running vertically up the rear of the cab from brass rod were fitted. There should be a slightly larger gap between the fuel tank and tool boxes on the side, which I assume have been cast closer together to make the casting / mould easier as a compromise. I chose to ignore this especially as my model will be in Southern Black livery and the lack of gap is not obvious.

Overall:
This is a relatively simple kit resulting, with a little care, in a nice model. The cast components were on the whole clean, and fitted together well, although the front cab windows were not well defined. The instruction sheet was very simple and lacked any prototype backgrounds or history.

General notes on working with cast resin:
Cast resin is by nature quite a soft medium and files / drills quickly and easily with very little effort. I would suggest avoiding self-tapping screws and ensure that you use the correct tapping drill for the thread that you require otherwise threads can be easily stripped. Also avoid over-tightening screws.

Prior to painting clean the resin body thoroughly and I then suggest the use of a plastic primer. I use an aerosol from Halfords.

It is a common practice with white metal or brass kits, once a model body is washed prior to painting gently heat the body, in an oven, to ensure it is totally dry first and also to give a warm surface for the paint to adhere to. I must note here that extreme care must be taken with cast resign bodies with this practice otherwise warping could occur.
