Mounting
the second side wall gave us a first impression of what the spray booth would
look like in the end.
At that time we had realised that the cover panel would sag, so we decided to
reinforce it with one of the spare acrylic glass strips that had been left over
after cutting the side walls.
We
stuck the strip vertically to the front edge of the cover panel with some super
glue. Afterwards sagging was no longer an issue.
Once
the cover panel was mounted to the side walls, we adjusted them accurately and
screwed them to the ground plate.
