Had to secure frame to floor and wall, them mount support struts in place, and block them to wall for strength.
The struts are in place and leveled . Had to mount them 100mm lower as the SG is dropping that much and will enter the helix at about 1015mm.
So that's 12 m of framing (only 3m to go :) )
The blocks screwed to the wall will help strengthen the supports.
Now I have to remove both frames and cut out the insulation panels to be liquid nailed to the back
Then fix them back into position to fit another two sheets of plaster on the front.
Thank goodness the weather is much nicer now.
