Me,Tom and Phil went out to Mt Bigs school with Dave today to work on an extentionFirst off we stopped off at Placemakers to pick up a few items such as nails,6 sheets of ply,H4..My jobs were to get measurements of the studs lining up with the rafters that slope on 8 degrees.Skilsaw was used on an 8 degree angle to trim the top of the stud so it would fit into place.4 inch nails were used to hold them in place.Dwangs were 355mm in length and were hand nailed in as the nail gun had no battery left.The ply on one side of the building was nailed off and finished.Now that the studs are all in place along with the dwangs it is ready for ply.

We then returned back to class,All of the house walls are now erected in place.I measured the large opening in the lounge for the big window.Turned out that the top of the opening was out 15mm and the bottom was out by 60mm,Which is a massive problem!,I used a sabre saw to cut through the nails holding the studs in place.Ear protection was used while cutting.Once these were out we re-marked the bottom plate.Hammered the studs to the right spots and nailed them into place,ready for the window to be put in.

Cam and Matt then picked up that the top plates on the exterior wall on the wet area side was out by like 5mm.This was fixed so now we have to string line our internal walls and then get them all plumb.A peice of 4x2 was used to move the exterior wall while we got the doger block all sorted and in place.

Exterior Walls.

One of the main walls in the hall way.

All walls are stood.
The walls went up quite fast as the numbering made it easier,We later on found out that the linen cupboard wall was not made up,So we are now in progress with the making of that wall.The internal walls are braced from the top plate to the exterior top plate.

So this morning,We went up stairs to have a quick revise over the different timbers we use in our country ect,After that we then went on to learning about the different treatments for timber that we use for our builds.H1.2,H3.1,H3.2,H.4 and H.5The higher the the number the more protected the timber is against Boreing,Fungus,Dampness basically rotting.H5 are used for piles and fencing along with H4.

H1.2 is mostly used for framing,It is protected from the weather above ground,But with an exposure to moisture.It is protected from borer and fungal decay.

H3.1 and H3.2 is exposed to weathering above ground level with periodic wetting,basically protected against Fungi and borers.
Also used for decks and external beams as long as it does not touch the ground.

H4 is exposed to the weather in the ground or in fresh water,ground contact or conditions of severe weathering,mostly used for fence posts and landscaping timbers.

H5 The highest treated timber,Used for ground contact.To be used for piles posts for decks.

We were given a small chart with a summary as to what each treatment does.Once we had been in the class for an hour we moved back to the EShed where we done our first Wall assessment.After this Me and Tom set out to correct yet another few walls,The first one have the lintel put in the wrong way and the second being that they used 90x45 for a lintel over a wide space when 6x2 was ment to have been used,plus gal nails were not used for the lintel.I cut the 6x2 up to the correct length,1670mm then used galv nails,nailed in at 300mm centers,4 nails for each 300mm row.Each row to be shot in different directions.This is done so the lintel has no way of coming apart at all.

After this I then finished nailling in the Second top plates,After the walls were plumb,A few others went around and used the plumb bob,We then braced From the inside and removed the outside braces as they will be an obstacle later on in the build.

We all started with 1 hour session in class in regards on how to use a plumb bob and how to straighten our frames using bracing.I never knew how to use a plumb bob or what it was untill today.It is quite an interesting tool to use.It is set up at the top of the Top plate,A nail is nailed in for the string line for the plumb bob to be attached to.The string is to overhang over the timber.A 100mm gap is something managable measurement to be used.A rule is then used to measure from the inside of the string to the outside of the exterior frame at the top plate.Once that measurement is gathered then the next one is to be taken from the bottom plate.If it is 103mm at the bottom then it is out.which would mean the bottom plate is sticking out an extra 3mm.

Dodger block-3 blocks with the same width and a string line with a nail at each end.

If there is rain and or wind then it is practical to use a bucket fill of water(Plumb bob in bucket) as this stops it from moving when trying to get the measurements.This is a highly accurate way of finding plumb for the walls.

Spirit level and straight edge is used at each corner of the building to get level,then bracing is nailed in at the top and can then be used as a guide to move the wall backwards and forwards.So that the right position can be found,Once this is done then you can brace to the boundary joists to keep it in the correct position.For the bigger spaces.Such as the lounge,bracing will come into the middle of the room(sercured to blocks to the floor) as the outside of the house will need to be wrapped with builders paper.It is also vital that the internal walls are inside the house before the last exterior wall is sercured in.

After being in the class room we went out to the workshop to continue squaring up the remaining walls.Once we had done that,Me and Brad,were given the task of setting up a dodgem block,on the outside of the wet area exterior walls.We removed a quarter of the tacked nails in the bottom plate then used a block and ran it between the string line and bottom plate to see how much we had to move the plate.At 600mm centers we nailed the plate down,A dogyu was used to move the bottom plate to the right spot.Then the nails were used.
