As a result of the my success recorded in my blog post of 13/11/2011 I managed to do two S wagons with the cantilevered loads and another K wagon with a load enclosed within its sides.
The timber castings for the loads came from two different sources to the load in the earlier post namely, In Front Models and some polyurethane timber stacks I found in a plain plastic bag a few years ago (in Toms Hobbies I think).
The end result is that I now have three cantilevered loads each with different timber stacks in one K wagon and two S wagons plus the normal load in the other K wagon.
Of course the next step was to see if the timber stacks extending out of the ends of the wagons would interfere with each other on curves. I placed the wagon with the wide central load projection next to a S wagon without timber then the others were coupled so that each central stack went between the two outer stacks on the next wagon.
Here is a video showing that there was no interference on my 762mm (30") curves.
The next obvious step is to tie down the tractors in the following S wagons. I will have to paint them and then tie and brace them as shown in an AMRM article by Graeme Brown some years ago (AMRM Issue 229 August 2001). I am sure that the VR way of tying down a tractor in a 4 wheel wagon would be much the same as it was done on the NSWGR.
I also want to try my hand at tarping a few wagons using the EZ Line to stretch the tarps 'tight' but I have loaned my Day of the Goods Train book which has the dimensions of the tarps in it to another modeller. I think a phone call might be in order soon.
