So to start off the day I got involved with the Plywood,We had to work out the correct measurements for it to be placed,Looking at the plans for the likely wet areas of the house,such as bathroom,laundry and toilet,The ply is used because the water does not get obsorbed by the wood,whereas with chipboard it goes all mushy and soft.The joists were glued with gorilla glue,then the plywood was placed down and sledged into place.When it was all flush,a chalk line was used to mark down the joist line underneath.At each end of the floor boards,the air compressed nail gun was used and at every 150mm a nail was put down.The next rows were nailed at 200mm,the nails used were 65mm galvs.Each board was put on the stands and cut with the skillsaw,I added 39mm(The leeway from the blade to the flat metal base,plus the 15mm that needed to come off the boards so they were flush with joists barriers.We had to work out the area of the wet area to see how many ply boards were needed.So 6780mmin length and 2000mm as the width,6.780x2.000mm=15.56m2,each plyboard =2.400mmx1.200mm=2.88m2,15.56m2/2.88m2=5.8,rounded to 6 so 6sheets required for the wet area.

The other half of the class started an exercise with the chizels making a box for the oil stone to be kept in,The bottom is to be super tight and the top,(lid) is to be loose.
