A few years back, we received several fir floorboards recovered from demolition at the Riverview Hospital site. The institution was constructed around 1913 and the boards looked worn, scratched, and were full of old square head nails. The tongue and groove planks were in different thicknesses, but we were able to pair up some matching sizes.
In order to focus on the floorboards, we tried several table designs including wood frames and legs. In the end, we settled on steel hairpin legs from Rusty Garden (on Amazon) in 2 sizes: 12″ and 16″. The footstool would fit underneath the coffee table. Minimal sanding of the boards removed any burrs or slivers. A mix of 30% thinner plus 70% polyurethane was used to seal the wood in a thin layer without gloss, giving it a light sheen and a handworn look. The fitted boards were glued with PL polyurethane.
The sizes are: table, 40″x 20″x 18″tall; footstool, 22″x14″x14″tall.
