Plastic welding

We've ordered polyethylene sheets and John is adapting his heat gun to be a plastic welder, so as to create a new water tank.
He's drilled a hole in the hull to let our mixture of diesel oil and water drain out, and plans to pull out the sections of rail we put into the bilge on top of the melted lead for ballast. Then he will refill the bilge with concrete and put the new water tank on top.
Our girls always complained that the water on the boat tasted of the fibreglass lining of the original tank, so there will be no more of that.
The diesel leak was extremely small, but he is welding a new plate onto the bottom of that tank as well.

As we wait for the arrival of the polyethylene sheets, we will get on with fitting the interior finishing skin to the salon, head and galley....nevertheless, this new wrinkle does likely mean a later completion date for this project.
