We made the datum line and made a lip from sheet metal, this is done to enable one to split the two moulds apart. After sanding down the plug and filling in the space between the sheet metal and the plug, we applied several layers of wax on the body to get it as smooth as possible. Then blue gelcoat was applied on to the body.
Now applying 4 layers of glass fibre on top of the blue gelcoat - just after the gelcoat become tacky. The Sheet metal lip was taken out just before applying the glass fibre layers at the bottom side of the plug. Timing with these materials are very important!
The bottom mould is taken off.
Top mould also has been taken off, but there was pollyfilla attached to the mould and we had to take it off before cleaning the mould. The white pieces seen in the picture is the pollyfilla which had stuck to the mould.
The two moulds on top of each other. Someone is inside...
What we have learnt:
- After shaping the body out of the high density foam - JUST APPLY PVA PAINT!
- Sand it down after several layers of PVA, if there is still bumps or holes, paint it again and sand afterwards until extremely smooth.
