From plug to mold
 Home   Dinghy   
 
After the plug is waxed, a layer of white gelcoat was sprayed on the mold and a number of layers of glass were applied.
 
I heat formed 2 inch PVC foam and glued it to the layer of glass. The entire shell was then rough sanded.
 
  • This is what it looked like from the back end. Foam was added to make a stiff sandwich construction because the vacuum infusion method can load the mold if one is not careful.
  • The foam was covered with another layer of glass to make a sandwich construction.
 
This is what the mold looked like when removed from the plug.
