The powder coated pivots were collected first thing in the morning, and the results were great.
To secure the doormats to the grass we stitched in each corner.
The first fully assembled see-saw (minus the bell)
The bell issue:
It was a bit of a struggle to get the bells working. We tried out many different variations. The main thought was that the piece within the bell was not large enough, so thus had to move too far in order to hit the side of the bell and make a noise. Firstly we thought that a possible way to solve this was by having the central piece on string rather than stiff wire, so that this could move more easily. This did not work- it still did not ring, and it also was too difficult to attach the bell to the underside of the see-saw without the string being broken by the screw driver.
Next we tried making the central piece larger- making a mockup out of spare nails- again this was unsuccessful.
In the meanwhile, there was an issue with the third see-saw. This particular piece of wood was incredibly hard unlike the others, and so it snapped multiple screws and drills as the pivot was attached. Thankfully it worked in the end.
