Straight-grained, but less “interesting” wood: more useful for construction

Sunlight helps us to SEE: but it can affect the colour of wood

Branches cause KNOTS – which may be a problem in Structural Timbers

Be “suspicious” of wood that’s got blue, black or whitish deposits on the surface!
21
 
22
Even slight magnification helps us to SEE so much more, and to make judgments about the Wood

Musical Instruments are frequently made from Wood: which is both attractive and resonant

Pine resin has a very pleasant aroma

34
Mouldy Wood often has a “musty” or “mushroomy” smell to it

TOUCH

37
All timbers have texture - which influences what they are best used for
38
Slow-grown Softwoods have a much more “even” and “solid” texture

Feel the whitish stuff on the surface... Is it slimy?
41
Feel the whitish stuff on the surface... Is it slimy?
Or is it sticky?
42
Dried Resin on the surface of Pine can appear as whitish patches

What are these timbers’ Moisture Contents?
52
 
53
“EMC” is the only “correct” Moisture Content for any timber in service

…it’s a collection of Circuit Boards that measures electricity!
57
The tiny, uninsulated pins that are supplied as part of the Meter are often worse than useless
58
For greatest accuracy, we need to use a Hammer Probe with long, insulated pins…
