Setting up

1st step after the briefing on task duties was setting up, which Deon is responsible for.


It involved clearing and prepping the floor. laying down the girders / gussets, setting up frames and creating a brace so the frames wouldn't move.


Vaughn gave us a demo on how the cnc works. He used it to cut out the frames. Each frame was cut into two so we could get the most of the mdf were using. I liked the cnc because of its precision and how clean cut and accurate it was.


The frames were then taken to the lofting floor where a team assembled them with great accuracy for the join had to be precise. Some had to be redone because the gaps between the joins were to great. cL showed us that a good way to test the join was to fold a piece of paper and and try to wedge it in between the gap and if it slid in it needed to be redone.


I then went onto autocad and got all the measurements needed. So we could start to mark out on the ground where the girders and gussets needed to be.


We started with finding the most convenient place to build the boat. This is so we can make the most of the working space we have.


Then we drew a CL 5.7m down the centre. We drew it at 5.7m so that when we lay the centre guider on the line we would still see 100mm of the line on either end of the girder. This makes it easier to transfer the CL onto the centre girder.


We then used a long trammel to draw a straight line across the fp that measured 800mm out from the centre line on either side. Repeated the same method on the ap. A straight line was then drawn from each ends of the 800mm lines from the fp to the ap on either side. (The markings looked like a rectangle with a line threw the middle going from the fp to ap)


We then started marking out the stations.


The side girders are placed (800mm offset from the center line on either side). The foreid point of the side griders started about 50mm foreid of station 6 and goes all the way to the ap. This is so when joining the angled girders the joint wouldn't be on a station. Reason cause it could cause some problems when assembling the frames.The angled girders started at the cL of the fp and ended at the foreid point of the side girder. Same on both sides.




Then after checking a few times and we were happy of the positioning of the girders. We gathered some weights to hold the girders down for when we glued.


Swept the ground one more time then started applying a glue called no nails ( which takes 24hrs to dry) to the girders and placed them into position. After all girders had been glued and placed into position we started placing the weights on top to keep the girders from moving while we waited 24hrs for the glue to dry.
