Forest Products Research Laboratory conducts a wide range of experiments on timber.
M/S of a man in what appears to be a library. M/S of the man taking a block of wood from the shelf. Panning C/U of blocks resting on a shelf like books, all labelled. M/S of a technician examining a block under a microscope. Extreme C/U, looking down the microscope lens, at wood particles. Exterior. Two technicians are inspecting samples of weathered wood hung out on frames. C/U of a weathered section of plywood. Interior. C/U of the plywood being gouged by heavy blade. Various shots of technicians in a workshop testing the strength of weathered wood panels.
M/S of a technician placing wooden baton in a tube in a machine - it is subjected to steam and great pressure. C/U of the steamed baton being placed into a mould for a spade handle - it bends easily into shape. M/S of two technicians placing a wood bar into a bigger bending machine. Various C/Us of wood being bent, C/U of a graph being plotted. M/S of a technician lifting the bent wood from the machine. Extreme C/U of a match being placed in a vice, a machine lowers a weight onto it. C/U of the technician operating the machine. Extreme C/U of the weight bending, then snapping the match. A similar experiment is carried out on a larger scale - a sturdy wood pole is subjected to pressure to test mine prop endurance.
C/U of a scientist examining wood. C/U of maggot-like death watch beetles chewing on samples of wood. C/U of wood with dry rot. C/U of wood in a high pressure tank, we see it rapidly absorbing blue preservative. A technician is seen operating a finger-join cutting machine, C/U of zig zag joints fitting neatly together. M/S of a technician testing the strength of roof rafters to destruction in a large machine.
