The response to the fall of our mighty oak was swift and resounding: first, grief, then grit. How could we find a way to honor this tree by giving it another life? Alongside an outpouring of memories came a slew of ideas. Could its wood be crafted into something usable? Could those who loved the tree take pieces for themselves?
A team was assembled to discuss exactly that. Chief Operating Officer Keith Powell, Middle School Head Lauren Railey, Carter Innovation Studio Director Cassie Kise, and Middle School English Teacher Charlie Raymond spent several weeks exploring how best to honor our beloved tree. Beyond this introduction to our first careful steps in repurposing the tree, a blog series will keep you informed around the status of Founder’s Oak.
The Science of Reclaimed Wood
An essential early step in the reclaiming process is curing. Wood tends to twist and check as it dries. A robust curing process allows wood to wick moisture and settle into its final shape and hardness, all while protecting against rot. Proper curing will yield bone-dry wood that won’t continue to change–wood that is ready for cutting.
“We think of wood as dry on the inside, but it’s actually pretty wet,” said Charlie, who worked as a furniture maker prior to becoming a teacher. “When you go to a store and buy a milled piece of wood, you’re relying on that wood to be straight so you can build something out of it. The best pieces will stay straight only if they have gone through a careful drying process.”
A tree as large and complex as Founder’s Oak will yield cuttings of different thickness. While the smallest pieces are expected to dry over the course of a single season, the trunk and large branches might need to be stored for five or more years. At the end of this process, the dimensions of the cuttings will have changed. Additionally, some of the pieces we set out to cure may have been lost to rot.
“Our particular kind of valley oak–quercus lobata–can be difficult to work with,” Charlie continued. “We can’t predict how much usable wood our tree will yield. Every piece of it is important to try to get as much as we can out of it.” That’s why it’s so important that we be strategic at this stage in where and how we cut the logs to cure.
Enter Nick Harvey of Bay Area Redwood, the expert we’ve hired to oversee the harvesting of the tree. Nick has been on campus managing a process that could span two months. “At this point, most of the smaller limbs have been separated from the main trunk. The branches off the main trunk are called “secondaries”. The largest ones are as wide as tree trunks themselves and will take years to cure. The smallest pieces will be the first pieces ready for processing.”
Once all of the smaller branches have been strategically cut and cleared away, Nick will partner with Kyle Dowd from Golden State Portable Milling on the milling of the main trunk. “Milling day will be a big day. Maybe a big two or three days,” Charlie commented. “The actual cutting of the main trunk will be noisy, but we won’t schedule it for a weekend. We’ll schedule it for during the week so that the community can see and be a part of what’s going on. It will be part of student learning.”
Speaking of Student Learning…
Summer conversations also focused on how to involve students in all aspects of recycling the tree, from these early harvesting steps, to curing, to cutting smaller pieces, and–eventually–to crafting. Though the viability of many ideas still needs to be assessed, one suggestion is to enlist students to help create proper storage conditions on campus and to have them oversee the curing of parts of the tree.
“Rain is not an enemy of this process, but sunshine is. It can twist and warp the exposed side and not the other. A better technique is to find a shaded area to stack the wood with space between each slab so that air can flow. Sometimes, slabs need to be treated against insects. We could involve students in discussing what chemicals might be used to treat the slabs against decay,” said Charlie.
Carter Innovation Studio director Cassie Kise shared similar thoughts about timing for next steps. “People don’t realize how time-intensive fabrication is. As Americans, so much of the supply chain process is taken out of our purview that we don’t understand how long things take to make. It’s important that we employ patience and instill those values in our students as well.”
Though fully recycling the tree will take a series of years, discussions of early craft projects are also underway, as are more general discussions about how to better integrate woodworking into the curriculum. “Ultimately, the tree will dictate what we do with it,” Cassie continued. “Once we gain an understanding of the materials we have to work with, it’s our job to expand the conversation to other members of our community, especially students. We also need to emulate our values as an institution. For example, wood that isn’t used to craft an item might integrate with our ecosystem in the form of mulch. Finally, we need to honor the spiritual legacy of the tree–the nostalgia and love encapsulated within it and how that should play into its second life.”
Though he acknowledged the tragedy of losing the tree, Charlie also underscored that Founder’s Oak deserves our respect. “Overall, this should be seen as a great opportunity to build our profile as an experiential school. We’re already doing that in the Carter Innovation Studio, in the art department, in our middle school Focus Days, and in our electives. Working with Founder’s Oak represents a huge opportunity to reinforce this.”
Seventh graders took experiential education to a new level for the past three weeks by getting off campus every single Friday. On September 18, they visited the Conservatory of Flowers and Botanical Gardens in San Francisco to investigate plant adaptations for science class. On September 25, they took a hike to Borges Ranch in Walnut Creek where they tested their stamina and resilience in the autumn heat,
