Tea Van [ Part 3 ]
Darjeeling Himalayan Railway Tea Van in 7/8ths
Tea Van Part 3Here is progress on the Tea Van base. One of the issues I found with aircraft plywood and the only drawback to its use is the inherent flexibility it has in one axis. As part of its design it is highly flexible in one direction and incredibly rigid in the other. After much playing around I used to rely on the larger support beams for rigidity and then realised that if I sandwich two layers of plywood cut in perpendicular directions the end laminate is rigid along both x and y axis and a perfect platform to build upon is created. The two images below show the layered effect and the final sandwich creates notches along the edge to align the rest of the build. |

I placed the two layers between foil so that nothing sticks to them as they dry and set aside overnight to cure under weight. (placed 20lb weight on top of the composite). Once dry I proceeded to add the remainder of the under deck details that will hold the axle boxes and couplers. I use small clips to hold all parts in place until the glue has fully cured. I try to keep the clips symetrical to help minimize any warping. |
