The plywood is Forestry Stewardship Council-certified Occume from Joubert. It was important to us to choose, as much as possible, materials that do not contribute to the destruction of the world's forest habitats. The FSC is an international non-profit organization. Here's what they have to say about their certification program:
FSC certification is a voluntary, market-based tool that supports responsible forest management worldwide. FSC certified forest products are verified from the forest of origin through the supply chain. The FSC label ensures that the forest products used are from responsibly harvested and verified sources.
We bought the plywood at Westwind Hardwood in Sidney, BC.
The lumber is Vancouver Island Douglas Fir. We bought most of it at Westwind as well. We have purchased some at Coastal Pacific Forest Products, just south of Chemainus.
The epoxy and the glass cloth is from Raka Epoxy, in Florida. Raka epoxy is a 2:1 formulation (West System, by contrast, is 5:1) with both fast and slow hardeners. We choose our hardener based on the season, and especially the shop temperature, and on how much working time we need.
We're also using some Raka cold cure, which is a 4:1 formulation. The cold cure makes it possible for us to keep working down to about 0 degrees C.
