27th June

Tools used: hammer, clippers, air stapal gun

today was spent on putting up chicken wire across the roof to stop the building paper from sagging.

This was done by rolling out a roll of the wire across the bottom. [first length already done] The second length was rolled out across the entire length of the roof, then stapaled along the bottom run. The sides were snipped. Then 2 of us stretched the wire up to the top purlin and was stapaled. This was repeated the entire length. Then the side were stretched and stapaled.

Then the process was repeated across the other side. Same for the end

26th June

Tools used: radial saw, hammer, 8m tape, drop saw, dog tail, straight edge, level, F clumps, gas nail gun, hand saw, hand plain

First part of the day we started on calculations on the length of the roof clading and the number needed to cover the build.

First we went over the roof over hang / 600mm + 30mm [facia width] + 60mm over hang of the roof clading = 690mm

Then we added this to the run [half the width of 7.2m = 3.6m] = 4.290m or 4290mm
then to find the length [or hypotanuse]  4.290 divided by 20 degrees cos = 4.565m [take of 10mm of the roofing iron sheet to give us 4.555m]

Then to find the area of the roof we took the length of the build 15.5m added .690 [over hang] x's 2 = 16.88m / then the side - 7.2 + .690 x's 2 = 8.58m / x's these together 16.88 x 8.58 = 144.83msq

Then to find the area with the pitch 20 degrees we took 144.83m x cos 20 degrees = 154.125msq [this is the roof area of our build]

Next we worked out the number of sheet required. Each sheet has a cover of 760mm [which means its the width after over lapping the sheet next to it]. We took the length of one side - 16.88m divided by .760 = 22.210 / x's 2 = 44.42m plus 1 full length per end which gives us a grand total of 46 sheets @ 4.555m / off cuts go to opposite side.

We then worked out  the paper quantity. Rolls are 1250mm wide [cover 1m] rolls come in 50msq
50msq x's .8 = 40msq / pitch roof area = 154msq divided by 40 = 3.85 round up to 4 - so 4 x's 50msq rolls of paper.

Rest of the day was spent building. Demolotioning our close couple roof exercise, as well as de-nailing each member. Then went through the build nailing the bottom of the trusses to the top plates. We run a string line and blocks to check the walls were straight, adjusted when required using F clumps to pull any truss down down, then nailed from the bottom when we could and top on the other ones with a gas nail gun.

 

Last we had to adjust a stud where the kitchen units are going, by cutting with a hand saw no more than half way through the stud [internal part of the bow] then we nailed a member to 1 side [min of 300mm member from the cut - 1 each side] 2 nails at the top / 2 nails at the bottom and 1 in the middle. Then the stud was pushed to straighten. Nailed the bottom off [same as the top part] checked with a straight edge / nail the top of the other member at the top / when checked if straight a wedge was put in the cut / checked again / when straight the bottom part was nailed in / wedge knocked off.
Finished with a hand plain taken any edges off.

25th june

Tools used: drop saw, radial saw, hammer, square, bevel, 8m tape, rule, pencil, level, hand saw

Today we continued with the close couple roof exercise.

We finished measuring the rest of the rafters, as well as marking out were they were to go on the ridge and top plates. The bird mouths were cut out and rafters nailed in place. Then we plumb each end with a brace being put up to keep the roof plumb.

Then we split into 2 groups to work on each end. We had the out rigger end, with the other group on the purlin end.

We were shown how to calculate the raking frame to get the lengths and angles. Then we cut them out by hand, with abit cut at the top so the ridge can set on it.

From here we cut and put in a jack stud to support the raking frame, with 2 other, to support the out riggers.

Then the out riggers were measured and cut and nailed in place, with the flying rafter nailed into the ends of the out riggers.

20th June

Tools used: hammer, router, F clumps, drop saw

Today I finished off the tie on the window lintel, by marking out the out line of the tie then clumping the tin plate around the mark. Routing it out, then nailing the tie in place to set flash.

After lunch we started on the 'Close couple roof exercise'.
1st we measured the length of the frame to get the length of  the  ridge board + the extra 300mm each end for the gable over hang.

Then we were given the angle of 30 degrees + 1m for the run - .013 for half the length of the ridge board = 987 divided by 30 degrees cos = 1.140 / then we added an other 300 for the over hang / 1287 divided by 30 degrees cos = 1.486. This was the length of the rafter.
Then we cut each rafter with a 30 degree angle at each end. Measure down 1140mm using a bevel to mark down for the birds mouth, which was 18mm with the other end running square from this.

We braced it, running a member down from the ridge to the frame to hold it in place.

18th June

Tools: hammer & nails, gas nail gun, router, 8m tape, pencil, radial arm saw

Safety gear: muffs and boots

The morning session we went over the different parts of a roof again.
Then had to draw up a 3D plan of a man hole in the ceiling, naming all the parts
  • Ceiling joist
  • Trimming joist
  • Trimmer
  • Curtail joist
  • Load bearing wall
The rest of the day was spent on the build. Finishing the purlins along each side, starting with the 2 rib purlins.
I carried on with putting in the last half of the lintel with John. Cut to length and nailed in using the gas nail gun at 50mm in from the side and at 50mm intervals down [skewed] 300mm apart.
Then we put the tin plate on to router out the shape of the tie.

13th June

Tools used: 8m tape, fold rule, knife, pencil, straight edge, corking gun with gib adhesive, screw gun, small saw to cut out small holes in the gib, hand saw to cut bigger holes

Most of the day was up at the other build carrying.

We had to clear and clean areas we were going to store and hang the gib. When the gib turned up we had to unload it into the house.

From there Mark and Cam show us how to put up the gib, doing one wall in a room. Cutting the gib to length [being hang horizontal - only need 2 sheets per wall], then showing us to measure from only one side to cut out holes for the hot points, and also around windows.

Plus also learnt about the bracing element, were the screws were put in at 50, 50, 50, 75, 75, 150 from the top and bottom of the sheet, and at 200mm spacings

12th June

Tools used: hammer, nails, gas nail gun, 8m tape, pencil, radial saw, straight edge, level, calculater
Safety gear: ear muffs, safety boots
 
First hour was spent with Matt learning about how to calculate the pitch and lengths of  roof [trusses]
using sine - cosine - and tangent. There are 4 formula's you can use.

Rest of the day we finished of the rafters for the trusses [at the ends]

Then went through and nailed the end trusses to the outside of the top plates with Z nails [1 each side]
   Z nail

Where the other jack trusses meet we had to chisel out abit of wood so the brace plate would set flash
[1 nail on the bottom / 2 x 25mm galv nails on each side of the plate 8 nails]

Myself and another student went around to check the outside corners were plumb using a straight edge and level. One corner was out so Mark explained the Dwangs  were pushing the stud out. So we removed the 2 dwangs. Put a clump on and screw it up until the wall was straight - using the straight edge to check. Re-cut 2 dwangs . checked they fit properly, then nailed them in using the gas nail gun

11 June

Tools used: Hammer, 100mm steel nails,8m  tape, pencil, gus nail gun, drop saw
Safety gear: ear muffs, safety boots
  
Morning session was spent going over the different parts of roof framing

Roof board -
Common rafters -
Cliets -
Hip rafters -
Jack rafters -
Ceiling joist -
Cripple rafter -
Out riggers -
Short hip rafter -
Collar tie -
Load bearing wall -
valley rafter - 

Rest of the morning and afternoon was spent putting up the end trusses. Because they are numdered [marked] on the truss plans we hand to put the right trusses in the right place and also the right distance apart, then tack them off.

Due to a couple of these truss rafters being used, new ones had to be cut using the drop saw

To nail the jack trusses together we used 100mm steel nails [2 top and bottom]
Cam explained if you were putting the jack trusses up by yourself you would nail a block in the bottom of the truss you are going to join the truss too.

5th / 6th June

The 5th we spent all day doing our first aid course 8,30 to 4,30
Most of the morning we concentrated on how to do CPR on both adults and baby and the ABC's - check airway, breathing and circulation.
Then we went over choking, how to dislodge whats stuck in the throat or airway. Again on both adults and babies.
The afternoon we went over burns [different types] and poisons.
We also got up in groups to talk about different aliments [the group I was in, had heart attacks]

The first have of the 6th we finished off the first aid course 8,30 to 12,30
we covered bleeding, shock etc..
Then finally we had to put it all together we a scenario of up to 3 things wrong with the victim

The rest of the day was getting our work on frames up to date and sent in to be marked
