I was out on site several times during the week and also on Saturday.
I have built all four frames over the week and added on the large cross beams on top.
I still need to insert some spacers under the frame and attach it to the wall.
As per usual it is grossly over engineered and very heavy.
I was quite pleased that I managed to build it out of existing timber that I have laying around.
Next visit - I will start working on the test stringers made temporarily out of particle board.
