A Girder to Far #3 - A Pier into Madness

Continuing the 3d printed bridge for the garden layout, we needed a concrete base for the 3d printed piers to sit on so after searching countless plastic bottle types I stumbled upon the ice cream containers and quickly realized it would suit my needs. I removed the bottoms of the container and slipped it into position, I packed the outsides with clay & small rock and proceeded to pour the wet concrete which is where the container sides started to bow outwars requiring some reinforcing with small sticks embedded in the clay. I vibrated the container for a few minutes removing the bubbles and covered it up for the night. When I removed the plastic this morning I was very pleased with the result. The second pier finished last night and when test fitting in place this morning the friction of the wood halfway down was to much, thus its halfway through receiving #40 sandpaper to enable a better fit. 

The rockwork has been redone somewhat, the white pipe has been removed and the water now dribbles down over the rocks. A concrete path has been hidden on top of the dam to allow people to walk over.

Cementing in a pad for the Pier, Ice cream containers are not ideal without reinforcing the sides I've discovered. 

The next morning, plastic formwork removed and im quite happy with the result, the exposed pier has been sanded back quite a bit due to a slight warp in the wood itself. Without sanding there would be no removing the printed pier.

Second pier almost touching the concrete, a bit more sanding to get it down flush

Playing with paint, also experimenting with various top caps with the lettering  '2024" & "Portland Railroad" embedded into the sides.
