What is the purpose of the peel ply?

chris asked me to blog on that topic. we nomally use the peel ply when glassing so i have been thinking about the reasons. First of all, we will be less sading after peel it off unless there is peel ply wrinkle. The other reason why we use the peel ply is that it's holding the shape of the hull because once it's laminating, it would be very tight. Third, it will protect laminted parts from dirt,dusty and any other things because they might be exposed many days, also there are red lines so we can see that it's peel ply which means we can look after laminated parts.

Before we vacuum the girder, we made a list what we going to need then we can work step by step. It is called stack

we talked about how we going to hold the topside foam after take off the nails so some people came up an idea then chris wrote on the cardboard. Chris explained about make some block to screw on the frame. As you can see the sketching how it going to be done

Girder

Kenny and I made the girder. Before we make it, we asked to Chris how it is going to be done. First of all, we discussed that what is the purpose of the girder so we answered that question.

- support to the cockpit sore

- firm / strong 

- streight / stiffness

- balancing

Chris also explained that he went up the middle of cardboard which two saw bench were holding each ends. The weight prssure the middle bending the cardboard so we need something support it. That is why we make the girder.

How to make the girder.

First of all, we need loafting this so we got all measurements from the Autocad then we figured out the thickness of planking as well as cockpit sore. After lifting off on the foam, we prepared to vacuum it.

The last work of the hull. Fill in the gap and sand it before the glass on.

This is the process which is setting up the deck frame. It is the same way when we set up the frame.

 we should remember that the centerline must line up. we need to keep the frames plumb. This is done with a level. Each frame is numbered and the location of this must match the grid.

This is the picture which we were gluing all the planking. Before we take those planking out, we should mark something like letter or number on the planking we can know which one was it. Then some people glue the planking and others put these planking back. After that we make sure take glue off which is squeeze on the planking.

After dry the glue, we started sanding to make sure it fair and take glue mark off. You must need the glasses, earmark and mask because there are lots of dusty when you are sanding. It takes 2~3days because it will take whole day for sanding and then you glue into the nail hole as well as gap and then the other day we are sanding again. One tip is that if you make own sanding block which make it comportable for using yourself, it will be much easier and quicker.

This is the picture finished the sanding. It looks more clean, smooth and fair.
