What is the preferred unit of measurement when using a scale? - ANSWER-Grams
Why should you keep the scale free of foreign residues? - ANSWER-Any residue left
behind adversely affects future use of the scale
If you must cut out a triangle from a thin piece of metal, which type of snips gives you
the best results? - ANSWER-Straight
When using straight snips to cut out a circle why should the cutting direction be counter-
clockwise? - ANSWER-To allow seeing the cutting line
Which type of snip can you sharpen when it becomes dull? - ANSWER-Straight
If you must enlarge a small hole in a piece of metal, which type of snips do you use? -
ANSWER-Aviation
If you are using the upper blade as a guide during a cutting operation, what kind of
snips are you probably using? - ANSWER-Aviation
What type of file do you use to sharpen shears or snip blades? - ANSWER-Single
What type of file is best suited for common filing operations? - ANSWER-Flat
What type of file is used for filing cutters and taps? - ANSWER-Triangle
Why is pressure on the back stroke usually not permitted when filing? - ANSWER-
Because the cutting teeth slant forward and the pressure on the back stroke will
probably break them off
When should you use a slight pressure on the back stroke when filing? - ANSWER-
When filing very soft materials
How should material for cross filing be positioned in a vise? - ANSWER-Near the vise
jaws to prevent vibration and, if the surface is straight, parallel to the top of the vise
When do you draw file a piece of metal? - ANSWER-When a finer surface is required
, What is the main precaution to remember when using a file? - ANSWER-Always use a
file handle
What are the correct uses of the flat chisel? - ANSWER-Chipping, and cutting sheet
metal, heads off screws, and flat stock
What are the half round nose and cape chisels used for? - ANSWER-The half

ANSWER-Pressing too hard against the wheel and allowing too much heat to generate
What type and pitch of blade do you use when you must cut solid aluminum? -

Which blade pitch gives the best results when you must cut a 12 foot length of angle
iron into 12 equal sections? - ANSWER-24 teeth per inch

inch
Why is it necessary for a hacksaw blade to have "set"? - ANSWER-To allow clearance
for the rest of the blade in the saw cut
What are the three types of blade set? - ANSWER-1. Alternate 2. Undulated 3. Raker
When using a hacksaw how can you position a stock to obtain the best results? -
ANSWER-Clamp the material in a vise, providing as much bearing surface as possible
so the greatest number of teeth on the blade will be engaged
Which stroke (forward or backward) is the cutting stroke? - ANSWER-Forward
What type of lever shear is used to make cuts on the inside of a sheet of metal? -
ANSWER-Scroll
Why is it possible to cut any length or width of cut with a throatless shear? - ANSWER-
Because the frame of the shear never obstructs the cutting operation
Describe the procedures for squaring a piece of metal with a manually operated
squaring shear? - ANSWER-Insert the metal between the blades and cut off
approximately 1/4 inch of metal; square the remaining edges by holding the trimmed
edge against the side gauge and making cuts one edge at a time
