In this episode, Dom tries to fix a leaky sea pool near Mousehole.

Dom Chinea tries out water dowsing so he can fill his new pond. He and engineer friend Sam Lovegrove fix some church bells and then put a surf lifesaving club's quad bike back on the beach.

Dom Chinea builds a drift car with engineer Sam Lovegrove. At home, he gets a digger in to make his new pond, and he and Sam have a go at gig rowing after fixing the club trailer in Hayle.

The workshop gets a new wall and floor. Meanwhile, Sam Lovegrove mends Dom's vintage motorbike for a nail-biting cliff top trial. Plus, cider, an orchard and an auction are on the menu.

Dom finishes the summer with new refurbished windows sealing the weather out of the workshop. Later, he and Sam head to St Agnes to buy Cornish tin to cast a workshop sign.
