Influence and inspiration is drawn from the works of Neolithic inhabitants of ancient Orkney. During the long bright summer days, the light on the landscapes inspires new designs, while the long dark nights of winter is the time when he is most productive in his workshop. Wood is obtained from sustainable sources and is processed on site with our own sawmill, from log to finished piece. The traditions and culture of the islands are an important part of Michael’s life and his work reflects his affinity with Orkney and its heritage of craftsmanship. All this results in Michael creating unique, tactile pieces to enhance any home or other surroundings.

As part of the Neolithic inspired range Michael makes ‘Petrospheres’. These are the stone balls found here, in various areas of Scotland and occasionally further afield. Nobody knows what they were for, child’s toy!, a show-off piece, or just because!,  but what we do know is that they are very beautiful and intriguing. Some are very simple and others are extremely intricate and ornate.

Michael uses mainly English boxwood to turn the ‘petrospheres’, although he has used other timbers like the yew and lately Lignum Vitae sourced from old wooden bowling balls. Boxwood you will see all round the UK. It makes excellent border hedges and ornate garden layouts quite often seen in large country house as well as topiary. It is used in instrument making and is a very dense timber which lends itself to making the little boxes (will take a thread) and gives a fantastic finish to the petrospheres.

He begins by turning a sphere. He has made a jig that goes on the headstock of the lathe to then hold the sphere for him to decorate. Some are 6 sided and some are 4 sided. As well as the different patterns, he has hollowed a couple with threaded lids, also added plugs and buttons of other timber and done some decoration using pyrography. Each one is sold with a little stand, but they are difficult to put down once in the hand.

Recently a petrosphere was sent to a foundry where a mould was made and then cast in solid bronze. A limited addition were cast and these are for sale along with the wooden petrospheres in our Gallery or on our website.
