This event is being rescheduled.

Learn to work with slate and build a fantastic permanent feature!

Building a dry stone sphere is challenging task, much appreciated by people of all skill levels.  Carefully stacked stone spheres and similar shapes have been built by a number of wallers and stone artists, sparking wonderment and joy when viewing pictures and even more so when when viewed in person.  As part of our 10th Anniversary, we have decided the time is right for a stone sphere to be built at the Stone Trust Center at The Scott Farm.

We plan to build a 5′ diameter sphere sitting atop a granite pedestal as a prominent new feature in our Stone Wall Park.  We will be using slate donated from Camara Slate in Fair Haven VT.   Over two days we will be splitting, trimming, and stacking slate.

This workshop will be run as a joint 5.20 Feature Build and a 4.70 Walling Day.  This advanced feature will require quite a few skilled stone workers to complete it on our tight schedule.  The 4.70 Walling Day ticket allows wallers who are Professional Members and DSWA-GB Level II or Higher Certified to participate at a nominal cost.

For those with a less experience (pre-quisites still apply, see below), the 5.20 Feature Build Ticket will provide an in depth learning experience, and allow you to work along side more experienced stone workers.

To celebrate 10 years of service for the preservation of the craft of dry stone walling we are paying our respect to the artistic side of the craft with this build as a memorial to all those who have contributed to The Stone Trust over the last decade. For board members new and old, workshop participants who trusted in stone, the professional wallers who carry on the traditions of the craft and, for the next generation and our generous donors who have believed in the Stone Trust,  this sphere will be our memorial for what we have completed and give hope and passion for the future of traditional Dry Stone walling.

In this workshop participants will get to learn about and gain experience splitting and trimming slate, as well as how to approach stacking for complex features, and setting up guides for keeping the geometry true.

Splitting and trimming slate will be a big part of this project to prepare pieces to the proper size and shape.  Meanwhile several participants at a time will stack and heart the sphere, rotating in and out so everyone gets a turns to split, trim, and stack.

Sphere construction is very tedious time consuming work. With every course that is built the outside curve radius changes. The build will consist of a few participants at a time building and hearting each course while teams of other participants work on banker blocks (stone shaping tables) with profiles that represent the shapes needed. By elevating the sphere on a 2 foot high granite pedestal the lower part of the sphere will be at a comfortable building height.   Later we will introduce scaffolding for completion of the second half of the build. This sphere memorial team project, along with the historic Dutton Farm Wall Rebuild,  we will merge the ancient craft tradition of walling with the increasingly popular art movement found within dry stone walling.
