Crafting Eight Large Rafters for a Church Spire Using Medieval Tools & Techniques

posted by Jason Kottke   May 13, 2019

In the spire of a Swedish church built around the end of the 12th century, eight large rafters (that are in spectacularly good shape considering they’re 800 years old) appear to be fashioned from the same tree using a technique that had not been documented before. So, using only medieval woodworking tools and techniques, a team set out to prove that those rafters could have been made in that way.

The woodworkers’ search for a proper tree to use (starting at ~2:55) brings to mind the recent kerfuffle over the replacement beams for the Notre Dame.

Finding a suitable tree for this experiment is not necessarily easy. Where do you find a tall, straight, even pine tree with no branches for at least 13 meters off the ground?

They eventually found a 195-year-old tree with 11 meters of no branches.

The pace of this video is so leisurely that it feels almost meditative at times, watching this massive log slowly yield to the woodworkers’ effort and ingenuity. Recommended if you’re feeling stressed about the pace of the world.
