TIPS ON USING YOUR BANDSAW

For all cutting operations the upper blade

guard should be adjusted to just clear the

work being cut (approx. 3mm or

only does this provide the best operator

safety, but it also brings the blade guides

closer to the work giving more accurate

results and easier control.

Use both hands to feed the workpiece into

the blade. The work must be held flat on

the table at all times to prevent binding of

the blade. Use a steady even pressure just

sufficient to keep the blade cutting at full

speed.

Always use a rip fence or mitre guide

where possible to eliminate any sideways

slip of the work. This is most important

when the table is tilted to an angle.

Always plan work ahead. The tradesmans'

rule is "measure twice, cut once". It is best

to finish a cut in one continuous operation,

but frequently backtracking will be

necessary. Turn off the motor and allow the

blade to come to a complete stop before

backing the blade out of the cut.

Remember that the blade removes

material during the cut. This gap created

by the blade is called the kerf and must be

allowed for when cutting to exact sizes.

Plan your cut so that the kerf is to the scrap

side of the line you wish to cut. If

necessary, allow a little more for finish

sanding.

RIP SAWING

This term refers to the cutting of timber

with the grain rather than at a right angle

to the grain.You can rip wood freehand to

a previously drawn line, but best results

are obtained by using the rip fence. If the

table is level, set the rip fence to the left

hand side of the blade. This allows you to

use your right hand to hold the work firmly

against the fence. The width of cut

indicator on the front of the worktable

shows the distance between the blade and

the right hand edge of the timber.

When cutting a bevel rip, with the table

tilted at any angle up to 45˚, set the rip

⁄

"). Not

fence to the right hand side of the blade if

the width of the workpiece allows it.

With the fence on the downhill side of the

table it will help support the work against

slip. The width of cut indicator shows the

distance between the blade and the rip

fence at the table surface.

CROSS CUTTING

This term refers to the cutting of timber at

right angles to the grain. This type of cut

can also be made freehand but the mitre

guide is used to ensure accurate results.

The mitre guide can be adjusted to a 45˚

angle to assist during mitre cuts, and with

compound mitre cuts.

Make sure the work is held firmly against

the table and against the face of the mitre

guide. Be careful to keep your fingers

away from the blade, particularly at the

end of the cut.

FREEHAND SAWING

The ease with which many different and

varied shapes can be cut is one of the

most important features of the bandsaw.

Select a blade suitable for cutting the

smallest radius in the work you have

planned.

When freehand cutting always feed the

work slowly so that the blade can follow

the line you wish to saw. Make sure not to

drag the work off line forcing the blade

sideways, or twisting it.

In many cases, it is helpful to rough cut

about 6mm away from the line in difficult

curves and corners. In the case of very

sharp curves which may be too tight for

the blade, make relief cuts onto the face of

the curve so that these scraps will fall as

the final radius is sawn.
