Close up of torn canvas on a Slaters Plastikard Cattle wagon
I've had a few positive comments about the torn canvas on the roof of one of my cattle wagons, along with a request for the method I used to model it. I'm not sure how well the method would translate to smaller scales than 7mm, but this is the technique that I used.
1. The area on the roof where the canvas is to be to torn is scribed with plank detail using a compass point or needle, held against a steel ruler.
2. A fibre glass brush is used to clean any debris from between the simulated planks and to help create some texture in the surface.
3. Seperate a piece of toilet tissue into its individual layers.
4. This next bit will only work on roofs made form plastic, if you're using brass, then maybe cyanoacrylate would work, but I haven't tried it!
Position the edge of the tissue to the underside edge of the roof and apply Liquid Poly, cappiliary action will soak the solvent through the
tissue and fuse the tissue to the roof. Leave to dry over night.
5. Once the tissue is firmly bonded to the edge of the roof, you can then stretch it over the upper surface of the roof, over the other edge and attach it to
the underside of the roof. To stop the roof warping, make sure you extend the tissue so that the whole of the underside is also encased with tissue.
6. Use a pair of tweezers and gently tear away the tissue in the area where the planking was applied, leaving the edges torn and ragged.
7. Apply Liquid Poly to the whole surface of the tissue and gently press the tissue onto the plastic roof. One or two drops of Liquid Poly is all thats need to
saturate the tissue and bond it to the plastic. Allow to dry, somewhere well ventilated!
8. Apply rainstrips, if appropriate using Slaters Plastikard micro strip
9. Paint the roof with appropriate colours, using enamel paint, this sets the torn tissue in position.
10. Dry brush the roof with a lighter colour to highlight the texture of the tissue and the torn edges
I think that just about sums it up
Best wishes
