Curved plank

I wanted to enhance the round shape of a round gravel surface and at the same time create a background for plants that otherwise easily disappear in the green surroundings and made a curved plank. I painted the front of the plank with brown pigmented oil that is usually used for wooden decks, but left the edges and back unpainted because I think the sun reflects back more light unpainted.

I am very pleased with the construction, which feels very stable, and am now looking forward to planting more plants next to the plank.

This is what I did: (Please also consult a construction expert for best results)

1. Measure the distance from the posts that will hold up the plank to the adjacent surface and between the posts and for support for the posts. Mark with a stone for example where the posts and supports will end up. To measure where the holes for the rear supports that have the task of stabilizing the plank will end up, I screwed joists at a 45 degree angle to the posts.
2. Dig deep holes for casting the plinths that will hold the posts and their supports. The recommended depth is frost-free, but I settled for about 45 cm depth.
3. Saw paper tubes to be used to align the posts straight (I didn't have much tube at home so I divided the short piece I had into three smaller pieces about 10 cm high).
4. Mix coarse concrete and fill the holes for the vertical posts. I waited to fill the back holes with concrete.
5. Place the three paper tubes at the top of the concrete for the vertical posts so they can be used as support when the post shoes are set in the concrete. Place the post shoes in the concrete, I used small pieces of wood between the paper tubes and the post shoes so that the post shoes stand straight up, I had also screwed a shorter wooden rule into the post shoe to make it easier to align (with a spirit level) the post.
6. Let the concrete burn according to instructions.
7. Screw post shoes at the bottom of the joists (point 1.) for the rear holes.
8. Screw the vertical posts into the cast-in post shoes (point 5), use a spirit level to ensure they are straight.
9. Mix coarse concrete and fill the holes for the rear supports and make sure that the post shoes on the supports are properly embedded in the concrete.
10. Let the concrete burn according to instructions.
11. Screw crossbars between the posts at the top of the posts. At the bottom, the concrete casting fulfills the same function.
12. Screw flat irons onto the vertical posts, I used 2mm thick flat irons between the posts and screwed these into the posts in the same round shape as the shape of the gravel surface. These flat irons are used to hold up the boards that are screwed into the flat irons, I chose to put one flat iron at the bottom and one at the top of the plank.
13. Drill holes in the flat irons with a drill bit at the desired distances between the planks. This step can also be done before screwing the flat irons onto the posts.
14. Screw the planks into the flat irons.
