Reflection

For glassing, by the time the team had got to the forward part of the boat they have developed a lot of skill, they could do a better job of the floors and got alot faster and more organised.

The gerder was done very well, they had a good vaccum, there was no spanning and there a good amount of resin on.  They learnt that where they put the hose was not the best spot for it to be.  They placed the hose which had mesh around it directly on top of the other mesh in the stack, this can cause a problem because once the vaccum is turned on there is so much preasure inside that bag that it will force the hose down and may create a dent/hollow in the laminate.  A much more effective way of placing the hose would be to create a dart and put the hose through the tip of that dart so when the vaccum is on it has no direct contact with the laminate.  The flange that was put on the gerder was next to perfect, what they did was they pre wet there glass out and layed it on there peel ply then grabbed a long metal straight edge and put some duraseal over the top so that the sglass doesnt get stuck to the straight edge, so they lay the straight edge down and put the glass over the top and turned the gerder over and placed it on top of the glass and coved it in.  This was a very good method of putting the flange on and i think it turned out perfect.  Thanks Chris.

On the blister which "Ugly Chris" and i were working on had made a mistake when we cut the top side and forward deck peice, we cut the foam but we cut to fit but what we hadnt taken into acount was that becase there was that blister we would hav to bevel the topside so that it can come in and we can plank the foam blister over the top of it.  But because we didnt allow for that we moade a bit more work for ourselves, to fix the problem we had make the first 2 strips lay inside on the top sides which was a harder task.

Ahh now vaccuming the deck, where do i start... we put down the glass on the forward part of the deck, completed that no problem.  Now the transom part and started on that and glassing that was ok, putting the vaccum bag down was the problem.  We put the vac tape down, put the bag over it, turn the vaccum on and watch, but, not a lot was happening, the vaccum was hardly working so we were going around trying to find where there was a hole that air was getting in.  Then "good looking Chris" went over to the transom and realised that there was resin on the vac tape and bag which wasnt sticking together.  After a couple minutes of playing around Chris desided to cut off a part of the transom and try and stick the vac tape to the temporary frame instead which didnt realy work either, not a good evening.  In the end after several attempts by Chris he desided to leave it and see how it was in the morning.  Later on we realised that there was a simple saw cut through the foam and that was the cause of not getting a vaccum.

  1. This is a very good reflection on the process used during the build. I can see from this you have learnt some valuable lessons on construction.
