Wood Tools Flashcards
Along with timber, wood tools can also occasionally be used on which materials?
Along with timber, wood tools can also occasionally be used on polymers
If wood tools were used on metals, ceramics, or hard composites, how would they be damaged?
If wood tools were used on metals, ceramics, or hard composites, they would be immediately blunted and ineffective.
What are the four main stages of working with timber?
the four main stages of working with timber are:
Squaring - to give at least one flat surface and one straight edge
Datum edge marking - to remind where to measure and mark from
sawing, chopping and paring - to remove and shape the wood
Preparing for (and) finishing - gluing, sanding and applying a protective/aesthetic finish
What does the ‘squaring’ of timber involve?
Squaring timber uses a planer to cut one surface so that it is flat and often involves also creating a straight edge as well.
Why is datum marking important before machining timber?
Datum edge marking is important before machining timber because
it records which face and edge are the flattest and straightest. This means all marking and measurements can be more accurate and reliable.
What are the two shapes used to mark out the datums on a piece of timber - the face side and face edge
the face side has a LOOP which leads to…
… the face edge and V-SHAPE on that edge
The two datums marked on timber member (piece) are used for what?
to measure and mark out from with try-squares, gauges, or steel rules.
Between the assembling and the surface finishing of timber products, what process is usually expected?
sanding is usually required between assembly, and definitely before, any surface finish is applied.
When sanding, the various coarseness or ‘grit’ being used should get rougher, or smoother?
When sanding, the grit should get smoother with each pass - from smaller numbers like 80 grit, to bigger numbers, like 600.
In which direction should timber be sanded?
Timber should be sanded in the direction of the grain?
Often timber surface finishes require particular coarseness or ‘grit’ to be sanded before they are applied. Where can this information usually be found?
Timber surface finishes which require specific sanding before hand will state the grit on the tin ro container.
