Posts in glass

I fitted the window from the other green house to ours, so that it would auto-open based on the internal temperature. I had to get a piece of the ridge extrusion as that is the other half of the hinge. I shall now refit the old window in another place as a manual alternative. I also managed to cut the pane of glass or the back center bit that matches to the two roof angles in the middle. I traced out on some card the green house roof angle, then just by eye scored the glass and it broke perfectly.
