This involved a fair bit of fussing around as I wanted to run the power saw along a straight edge to give a good cosmetic result.

Jim and Sandy turned up just as I was about to make the cut, so Jim very kindly held on to one end to avoid damage at the completion of the cut.

After coffee, I installed the hanger board on to the street level landing and then went on to install a supporting batten on both the street level floor and the landing.

I also modified the stringer template to suit.

Also the 22 mm offset board against the stud frame.

Finally I marked up some scraps of the 30 mm plyboard to reinforce the undercroft stringers where the "meat" of the stringers is only 90 mm.

I will cut these to shape at home during the week.

I will also be busy cutting the first run of stringers based on the template that I am also taking home.

Wednesday/Thursday

Cut out the 3 stringers.

I did not bring a saw home with me - so the final cuts will need to be made out on site.

Friday

I worked out on site and did a few construction jobs during my breaks.

Firstly I glued and nailed the reinforcement 30 mm plywood pieces in place at the top of the second undercroft run.

Next I completed the cuts in the 3 stringers, tidied up any rough spots and fettled them in to position against the landing and street level floor.
