Project PL16:
Having found more drawings on the PL16 family of pylons, I have decided to look into the possibility of making full scale model, with the option to scale them down to OO / N gauge and look at potentially selling 3D Prints of the towers in these scales. I have chosen the PL16 as it can suit most layouts from the late 1940s / early 1950s right up to the present day. A standard height tower in OO is roughly 34cm tall with an N gauge version being roughly 17cm tall.
For starters, I am currently designing the PL16 Scottish DD, this will then be followed by the Scottish D tower.
This is a long term project which will take time, but hopefully something useful can come of it in the end.
Attached below are the beginnings of the PL16 DD tower, with an outline one side and the bracing being done on the other.
