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.

The glue used,Gorilla Grip Express Glue,Takes an
hour to cure,To clean up the glue before cure,use bulldog cleaner,If the glue is swallowed,never give water,and do not induce vomitting,Seek medical advice,try to avoid getting the glue on your hands as you may have a skin reaction,For more about the medical side of things refer to the packaging or the website,www.holdfast.co.nz.This glue can be used on various materials.

Today we nailed the last of the piles down,We re-checked the spot levels on the sole plates and they were level.After that we installed the bearer to the top of the piles.Bracing was nailed to the piles so we could get the bearer level.A string line was put on the side with a block of 4x2 at each end and run another block down the line.Once these were all leveled,the barrier joists were nailed on.Our diagonals were out by 5mm so Matt and Cam Hit the bearers and got them to 17.091 making the bearers all square.We then started cutting up the joists,so 45mm at each end taken away so (90mm in total) from 7200 making the joists lengths 7110.To get the amount of joists needed,15500 length of the building divide by 450mm=34.4,rounded up to 35 and another one added for the one for nothing,so 36 in total.We managed to get all the joists cut to the correct lengths and tacked in place.Me and Brad started installing the blocks for the walling.The blocks width are 140mm,and we were to have them centered at 600mm,670 for the first measurement then used the running measurement to carry on,670,1270,1870 and so on.

Joists being put in place.

Joists all in place,along with blocks.

Our results for the day.

The blocks were made up for the potential manhole,The joists were cut and a square structure was nailed in.Next time we are back at tech we will be strapping the joists into place making the structure stronger.

Blocks for walling being installed.

The powertools I used today were;Nailgun and Radial arm saw.

Bearers being shaved then Joists being installed.

Before using the radial arm saw I checked around for potential hazards,such as off cuts,nails,anything that could get in the way whilst using the saw.I wore eye and hearing protection.I also never leave the saw untill it stops spinning,that    
way I know it cannot harm anyone.





When using the nail gun,I wore ear muffs and nailed into strong bits of timber,not to close to the edge causing the nails to fly out.I also made sure nobody had their hands in the way.
