Billboard

Navigation: Details

Such a large billboard needs a good groundwork. The ground cover is removed, a baseplate made of styrene. The first fine hole is already drilled.

The pole of the billboard is attached to the base with large screws (prototype). This part of the model is made as a 3D-print. I choosed resin with the highest resolution as material. The inner diameter fits exactly the pole width, the outer diameter fits exactly in the base plate of above.
This construction was made by myself with OpenSCAD (https://www.openscad.org), the printing was done by Shapeways. There is a big improvement in quality since I ordered something a few years ago. If I had knew this I would have made some details a little bit finer.
I reflected often about how to mount the billboard on top of the pole - since I was afraid simply glueing it wouldn't be enough. My solution is a threaded rod from top to bottom inside the pole to clamp the billboard to the pole - works fine!
I needed something to look like a real world mount of the billboard to the pole. I ended up with this - a cover to place on top of the pole after having mount the billboard with the help of the threaded rod.
I soldered thin brass wires to these photo etched ladders as a mount.
I drilled small holes in the pole to fix the ladders with their mounts at the pole.
I added some electrical cabinets and some fake wiring stuff to look like the real thing.
These brackets are for the lights.
Light brackets in place, but without LEDs so far.
First LED is glued in and still working - only five more to go.
Completely cleaned for painting, LEDs covered with tape.
Airbrushed with Vallejo primer and now drying for at least 24h.
The billboard got a weathering with a white wash first followed by a black wash. The big ads where fixed with a removable foto glue.
Last step was adding the cow with some rods in her legs. (Picture taken free hand via tablet under normal room lighting.)
