pliers squeeze, pincers cut or pull |
|
pincers squeeze, pliers cut or pull |

Pincers provide a mechanical advantage that's used to cut, pinch or pull an object. The force applied to pincers is concentrated to a point or to an edge of the tool which allows pincers to be brought very close to a surface. Pincers are typically used for removing objects from a material to which they've previously been applied, for example, to pull nails from wood.
These tools are called:
planes |
|
files |
|
chisels |
|
rasps |
Wood chisels are used to shape or smooth wood surfaces. They come in a variety of widths and can be used with hand power or tapped with a mallet when deeper cuts need to be made.
Measuring tools provide a convenient and easy way to compare object dimensions against:
a standard |
|
perfection |
|
a drawing |
|
each other |
Measuring tools give easy access to the wide variety of standard dimensions that are used to categorize and classify objects.
What is a caliper used for?
making perfectly vertical lines |
|
ensuring that surfaces are level |
|
transferring distances between objects |
|
measuring thickness and irregular shapes |
Calipers are similar to micrometers in shape but instead of measuring distances, calipers are used to transfer distances between objects. An outside caliper is used to transfer outside dimensions while an inside caliper is used to transfer inside distances. A vernier caliper is an extremely precise caliper (down to \({1 \over 1000}\) inch) that allows measuring / transferring either inside or outside dimensions.
Which of the following types of saws would you use if you needed to cut the wood quickly and weren't concerned with leaving rough edges?
coping saw |
|
crosscut saw |
|
rip saw |
|
hacksaw |
Wood saws are categorized primarily by their teeth. Crosscut saws utilize knife-shaped teeth that cut across the grain of the wood while rip saws cut with the grain using chisel-shaped teeth that rip the wood cells apart as the cut is made. The kerf (slot) made by by a crosscut saw is much smoother than that made by a rip saw but a rip saw cuts much faster. Coping saws are a type of bow saw used to make detailed often curving cuts using replaceable blades with fine small teeth.
