Q

What is the purpose of a Miter slot on a table saw?

A

The slots support the many jigs that are used with a table saw. Also as a reference for the alignment of the saw. The blade and fence are both aligned to the slot, ensuring that all three are paralell.

Q

Is the protractor scale on the face of the saw accurate or not?

A

It is not accurate-check the actual angle of cut by making a test cut.

24
Q

What is the common size of a table saw blade in construction?

A

10 inches

25
Q

A larger hook angle produces what kind of blade?

A

A more aggressive blade. Example: A Rip blade has a hook angle of 20 degrees, while blades for cutting two-sided melamine have a negative hook angle.

26
Q

Two common shapes of a Carbide Tooth Table Saw blade are what?

A

Alternate bevel ground teeth for crosscuts and on combination blades as well and Triple chip ground teeth are used for fine cuts in hard materials.

26
Q

Two common shapes of a Carbide Tooth Table Saw blade are what?

A

Alternate bevel ground teeth for cross cuts and on combination blades as well and Triple chip ground teeth are used for fine cuts in hard materials.

27
Q

What are some kinds of specialty blades for a Table Saw?

A

Dado blades and moulding head cutters are used for creating slots and contoured edges in boards.

28
Q

What are the specs of a Ripping Blade on a Table Saw?

A

10 inches, 24 teeth and aggressive hook angle of 20 degrees.

29
Q

What are the specs of a Crosscut Blade on a Table Saw?

A

10 Inch Blades: Higher tooth counts, around 80, and a less aggressive hook angle

30
Q

Should you use a cross cut blade for ripping?

A

The crosscut blade when used for ripping will over heat.

31
Q

What are the specs of a Combination Blade on a Table Saw?

A

A combination blade is best used for general-purpose work since they can be used for both ripping and crosscutting operations.

A standard 10” blade has 40 to 50 teeth per blade and a hook angle of 10 to 15 degrees.

32
Q

The combination blade for the table saw come sin two kinds: Simple and Planer. What are the specs of a planer?

A

The planer blade has teeth that are in ten groups of five producing a blade with 50 teeth. In each group, there are four beveled teeth and one Raker tooth. The Raker’s tooth has a large gullet in front of it which clears away longer shavings from the ripping action. The Raker’s tooth is square ground, while the four crosscut teeth behind it are alternatively beveled teeth.

33
Q

What is a disadvantage of the adjustable dado cutter?

A

The wobble cutter as it is called can create a lot of vibration, and is more difficult to line up cuts.

34
Q

Why should the saw blade on a Table Saw not project more than a quarter inch?

A

If your hand slips and passes over the turning blade, you receive a slight cut instead of losing a finger.

35
Q

A

The saw blade can shake the stock, causing you to lose grip. This can cause your hand to slip toward the saw blade or the work can be forcefully kicked back toward you.

36
Q

What happens when you cut into loose knots or a ripping into a split section of wood?

A

Both actions can cause a loose piece to hurl toward the front of the saw.

37
Q

Is it a important to use a stop block when crosscutting short lengths?

A

Yes it is.

38
Q

List three protective devices with which a table saw can be equipped?

A

1) Anti-Kick back fingers. 2) Splitter. 3) Blade Guard 4) Feather Boards

39
Q

What are the two machine grooves on a table saw used for?

A

Miter slots, used to hold miter gauges. Supporting jigs, such as the cross cutting jig. Also used as reference points to check blade and fence for paralell.

40
Q

What does a handle lock on a Tablesaw do?

A

It locks the height and tilt adjustments on a table saw.

41
Q

What is the narrowest stock you can cut on a table saw without the use of a push stick?

A

6 inches

42
Q

How does the hook angle affect the cutting action of a circular saw blade?

A

The larger the hook angle, the more aggressive the cut. Finishing blades usually have a small or negative hook angle.

43
Q

When using a mitre gauge and fence to crosscut a number of short pieces to the same length, what other device must you use?

A

A spacer block to eliminate binding between the fence and the stock.

44
Q

When you check the saw blade to see if it’s perpendicular to the tabletop, where must you place the square against the saw blade to get an accurate reading?

A

Between the teeth.

45
Q

How do you check the saw blade to find out if the tilt of the blade is exactly 45 degrees?

A

Cross cut, put the pieces together and check for 90 degrees.

46
Q

Bench grinders are used by Carpenters to grind what?

A

Plane irons, chisels, hatchets and knives. One grinder wheel reserved for sharpening is best.

48
Q

Silicon Carbide wheel is used for what materials?

A

Non-ferrous materials such as aluminum, copper and brass. As these tend to plug up the pores in an aluminum oxide wheel.

49
Q

Diamond wheels in a bench grinder are used for what?

A

Grinding and polishing ceramic, stone and aluminum alloy.

50
Q

What two types of tools are used to dress a grinding wheel?

A

A Huntington wheel dresser and a Diamond wheel dresser

51
Q

What is the best grit for sharpening chisels?

A

80 Grit

52
Q

What determines the hardness of a wheel?

A

The Type and Bonding material.

53
Q

Why is it better to sharpen tools using a lower RPM?

A

Less likely to overheat.

54
Q

What does maintaining a bench grinder consist of?

A

Maintaining bench grinders consists of adjusting the tool rests and truing grinding wheels.
