Q

The blade guides should be set forward until they reach the ______? of the saw blade

A

Gullets

21
Q

Describe the procedure for checking the blades tracking?

A

1) Adjust tracking control (behind the upper wheel)
2) While wheel turning, adjust control until the blades are at the centre of the tire, and stays there for 5 to 6 revolutions.
3) Once adjusted - tighten locking mechanism

22
Q

Purpose of control switch?

A

Turn the power on and off

23
Q

Purpose of the arm?

A

Supports all components above the tabletop

24
Q

What is the source of power for the band saw?

A

Motor and drive belt

25
Q

What does the drive wheel do?

A

Located at the bottom of band saw, gets power from the motor, and drive belt transfer that power to the saw blade.

26
Q

What is the upper wheel’s functions?

A

Upper wheel can be raised or lowered to adjust the blade tension. Can also be tilted to adjust for blade tracking.

27
Q

Tension control handle

A

Used to raise or lower the upper wheel when changing saw blades or applying tension to the blade.

28
Q

Function of: Blade slot and insert

A

Used when you change saw blades

29
Q

Function of: Tracking control handle & lock

A

Controls the tilt of the upper wheel, which adjusts the blade tracking on both the upper & lower wheels.

30
Q

Three basic parts of the upper blade guide assembly:

A

1) blade guide at each side of the blade
2) blade support at the back of the blade

31
Q

The function of a blade guide:

A

Prevent the blade from moving sideways or twisting when cutting a curve.

32
Q

The lower blade guide assembly has three basic parts:

A

Two side guides and one blade support.

33
Q

The function of a blade guard:

A

Blade guard protects you from touching blade above the blade guides.

34
Q

Table tilt:

A

allows you to tilt the table from 0 to 45 degrees

35
Q

Purpose of a wheel guard:

A

Upper & Lower guards protect you from the wheels of the band saw.

36
Q

Purpose of wheel tires:

A

Protect the teeth of the saw blade and provide traction between the drive wheel and the blade.

37
Q

What is lead?

A

When the blade starts to wander off the line of desired cut direction.

38
Q

Two reasons for Lead

A

1) Dull teeth - the blade will tend to cut toward sharp
2) Poor setup of the bandsaw - misalignment of the blade on the wheel

39
Q

The blade should have the bottom of the gullet aligned to:

A

Centre of the crown of the wheel, not the middle of the blade.

39
Q

How to secure dowel when cutting?

A

V block, with nail in centre to hold down the dowel. Nail will prevent dowel from turning as cut is made. or clamp a square block to each side of the dowel.

40
Q

Cross-cutting on a band saw?

A

free hand or mitre gauge

41
Q

How to start circle cuts on a bandsaw?

A

Start across the grain rather than along the length, grain will push blade out of the line of cut

1) Cut line is approx 6 mm from edge of stock

42
Q

Cutting the curve requires what?

A

A blade with adequate set to it’s teeth

The more set, the smaller the radius that it can cut.

43
Q

3 types of blades used with a band saw:

A

1) Fabric cutting blades
2) Metal cutting blades
3) Wood cutting blades

44
Q

Qualities of a metal-cutting blade:

A

1) 14 to 24 teeth per 25mm

45
Q

Skip tooth blade has how many teeth per inch?

A

1 to 6 per inch

46
Q

Regular tooth blade has how many teeth per inch?

A

4 to 10 teeth per inch

47
Q

Regular teeth have two kinds of tooth blades, name those two types

A
