When a customer asked me to put a "village Green" on his O scale, high rail layout I said okay (without knowing what I was going to do.) He wanted something like the green he remembered as a boy growing up in western Massachusetts.
I had a large space in the middle of the O scale village. We had scratchbuilt about a dozen structures that ran down either side of the village. By placing a "green" in the middle, it split the center of town into two main streets and visually looked more realistic.
I started by cutting an oval from a sheet of 1/4" thick Foam Core board and cutout the pond area in the middle. I glued the foam core down to the road surface and held it in place with weights until the glue dried.
I cut several rows of stones from a Scenic Express urethane foam wall and glued them to the edge of the Foam Core.
The whole green was painted with earth colored paint and finely sifted sand and scenic foam were sprinkled into the wet paint. After the paint dried I sprayed the whole area with dilute matte medium adhesive and added more grass and fine sand.
The statue is off the top of a bottle of Jack Daniels. I painted him and put him on a wood base. He's got a pigeon sitting on his hat.
The benches are store bought. The fence posts are made from 3/16th square stripwood with a map pin stuck in the top. Holes were drilled in the sides of the stripwood to hold the brass rods.
The "lake" is a painted bottom with Magic Water poured on top. Several ducks were placed in the pond.
This was an easy project that adds a lot of life to the little village.
