we managed to finish setting up all the frames on thursday, and today we are strip planking.
an interesting note: we layed a couple of strips yesterday afternoon so that today we will be able to have more people working on strip planking, otherwise there wouldnt have been any space for all of us to work.
when we set up the frames we mathed them up with the centreling and parallel to one another, but what we didnt do was correct the twisting. so thats what we did yesterday. and on wednestday we finished setting up the last frames 0-3 i think, the ones right at the bow.

Work Experience
last week i did work exp as our timetable states.
i worked at Kevin Johnson Boatbuilders, doing mosly sanding... and a bit of laminating with vynalester, which was very simmilar to polyester but not quite as bad.
what was different though waas the glass we used, we were reinforcing the joing of a transom that had been extended. we used 1 layer of chop strand and then 3 layers of DB and one layer of choppy after wards again to finish it off. i asked why, and they said the choppy was to give a better bond to the previous layer.
sure it was strong but it was also very heavy!!!
and the transom was made from 16 layers of glass. the first thing i said when i saw that was it is heavy!

Gougeon frames
ok so a while ago i bought the Gougeon brothers on boat construction book, i got a second hand copy of the new revised (fourth edition) i think the latest is the 5th edition.
and i read through the frames chapter. it was kinda interesting to see different ways to set up frames etc but from having set up cnc cut frames i and really see how inaccurate and slow some of the old ways are. altough they have their benifits. and reading about them has definitly made me improve my understanding about different ways to set up frames.
im not really sure about what else to blog about so for now ill just leave it at that.

Half ship model
i spend most of wednesday working on my half ship model. im at the point where there are a few places that need more sanding but the overall hull shape is nearly correct. ive also sanded the transom to a 10 degree angle with a radius. it looks ok, but i think i could have done it better if i had slowed WAY down. i was going pretty slowly already but i think i should have gone even slower. today (thursday i planed to to to uni to finish off my half ship model but i decided to stay at home and catch up on my blogging and a few other odds and ends that needed doing)
First week back semester 2 setting up frames
ok so over the last week we started setting up the frames for our boat construction.
on wednesday i spent the latter half of the day with a couple of other guys. we started cutting up the cedar that we are gonna use to strip plank the hull of our boat.
this required lots of setting up on the spindlemoulder we ended up using 2 blades (1 or 2mm thick i think) set at 8mm apart with an 8mm gap between the bottom one and the bench top. with this way we are cutting 2 planks at a time and we are wasting minimal wood. (overall very efficient).
we also spent wednesday dismantleing teh old frames that Chris' class used to make their boat and we stuck all of them through the speed sander. some of the other students also used a template to copy cut (router) slots into the old frames so that we would just beable to slot them all together (check that they are all level, true, straight, horizontal, etc) and screw them down, then start planking.
on thursday we finished cutting all the cedar wood (i think we ended up with nearly 50% more planks then Chris' class used on their boat, and we cut all of it in under 1.5 days. aparently it took them a week to cut all their planks).
that same day we started setting up the frames and realized that some of them had not been sanded/routered so we had to do that too. about half way through setting up the frames we noticed how inaccurate Chris' class had set theirs up because all of their lines on the floor (stations) were off by up to 4mm!!!
im really glad we are setting up ours differently...
on friday John and i started setting up the deck frames and started using the ....... arg ive forgotten the name! the tool to check heights of different things, where u look throught the sight and check the cross hairs, and some one else holds up a pole with a steel rule (or simmilar) for you to read off.
so this week we are doing dayskippers (which ive already done so im working on my half ship model), and on friday we should be able to finish setting up the frames so they are ready to start strip planking. yay
