today we finished off the last off the purlins around the house. we had to start putting the purlins in at the  bottom instead of the top of the studs on each 7.2m side of the house because the ridge of the roof was not straight on these sides. so same again the purlins were put in on a chork line that was marked for each purlin at 715mm from top to top of each purlin. we staggerd the longer purlins so they were not all nailed into the same studs so they wouldnt have to much stress. the nail patern was a nail at the top and bottom of the width of the purlin into the studs to leave room for the bolts that go in the midle of the two nails. today we used hand tools, hand saw, radial arm saw, chork line, ect.

today me regan and jesse were straightening up the purlins that were naild off incorrectly. they were incorrect because the meshys were spose to be 715 mm between the bottom of the purlin above to the bottom of the purlins below. we began straightening them up by running our eyes along and finding the bows in the purlins. once we found were the bows were we messured and moved up or down and renaild to the 715mm. we found that we needed to saw 10mm off almost every end to get them straight and correct.
today we used the drop saw, hand saw, hand tools, chork line and 4inch nails.

chisel

today i finished off my hand tools exercise. we had a plan that had different types of joints on each end and the finished product had to have a square in the middle that was 300 mm on all for sides.
after i finished that i joined the other people on the house and finished nailling off all the hip raffters.

thurz 17th work ex

At work experience today we used a digger to dig 3 holes that were 2.2 meters deep and then craned in 3 poles that were 280 mm diameter s e d poles for the support of a hay shed. When we were craning them in we used a string line off the corner post that was already in to get the exact depth the poles needed to be. Then we used sol plates to hold the poles steady while we braced them up using spear timber a nail gun pegs sledgy and a straight edge spirit level. Tomorrow we are going to poor 1 meter of concrete in each hole to support the poles so the don't sink  and to make them permanent. Then once the concrete is in we will fill the rest of the hole with dirt and the start building the roof

oil stone case

we were given 2 peices of d4s timber at 300mm long. d4s= dressed 4 sides. and told to turn them into the oil stone case that was on the instruction sheet.  once i had marked the stone size onto the wood i chiseled around the edge about 3mm inside the my mark to keep the edge from chipping off. to do this i used a rule and pencil to mark out the messurements and to guide me where to chisel and how deep to go. after chiseling the center out for the stone to sit in i did the same with the top peace of timber exactly the same. the bottom of case had to be pressure tight to keep the stone in and the top of the case was 1mm looser so the stone was easy to access. after case was made i put the top peace back in the vice to plane the top to make it prezentable and so it matched the task sheet. the messurments were 35mm in center form each end and then planed 5mm 45degree pitch ether side of center.
