SAWING TECHNIQUES

Starting:

It is best to begin the cut at a point or corner because it

isdifficult to smoothly blend in start and end points when start-

ing on a side. When cutting out circular shapes, saw into the

pattern line in a crosscutting (acrossthe grain) direction. If the

starting point must be on a curve, make it an outside curve.

Burrs and knobs are easier to sand on an outside curve.

Sawing:

Feed the piece to be cut slowly into the saw blade while

maintaining downward pressure on the piece. Do not force

it into the blade-let the saw blade do the work. The speed

at which you feed the wood into the blade depends on the

type of wood you are cutting. Harder woods should be fed

more slowly than softer varieties. Feeding too quickly into the

blade may result in the blade burning the wood, bending or

twisting of the blade while sawing, a rough edge on the cut,

or the wood jumping on the table. Do not apply sideways pres-

sure on the blade. The downward pressure on the wood may

be applied by hand or the hold down foot.

Straight-line Cutting:

A small amount of set isformed on one side of most scroll

saw blades due to the manufacturing process used to produce

them Because of this, most blades do not cut straight

parallel to the blade. The set causesthem to cut afew degrees

more to one side than the other. To saw a straight line, the

work should be angled approximately 2to 4degrees to com-

pensate for this. This may be accomplished freehand or with

a guide board. The same technique should be used for straight-

line ripping. Besure that the saw blade isfollowing the layout

line and not the grain when ripping. (See Fig. 3)

FIG.3

Turns and Corners:

Scroll saws are capable of producing 360

turns

while cutting. The kerf left after a turn is approximately

1/2 the width of the saw blade. When you want to

cut a point, simply turn the piece the desired amount

while maintaining downward pressure on it. It is not

necessary to cut past the point and then restart, like

the normal procedure for a band saw. When cutting

curves, slowly follow the pattern line, turning the piece

as you go so the teeth are following the line. It may

be necessary to install a smaller blade when trying

to saw an extremely tight corner or radius to prevent

the wood from jumping on the table and to prevent

blade breakage. (See Fig.

Bevel Sawing:

Bevel sawing is sawing with the table tilted, creat-

ing angled sides on the project. This sawing technique

may be used to create inlays, decorative letters, or

to put shapes into animals or other objects to be

carved. To bevel saw on the Hawk, loosen the table

tilt assembly knob and tilt the table to the desired

angle. (See Fig.

Stack Cutting:

Stack cutting saves time by cutting two or more

pieces simultaneously. Simply stack the work pieces

on top of each other and draw the pattern on the

top piece. The pieces may be held together with dou-

ble faced tape or nails may be driven into the scrap

areas. Cut out the pattern on the top piece and dis-

assemble the stack. Be sure that the saw table is per-

fectly square with the blade before sawing. (SeeTable

Squaring Procedure) If it is not square, the pieces will

not be uniform in size. The stack should not exceed

2/1

in height. (See Fig. 6)

Sawing Inside Openings:

Sawing inside openings is a common and frequent-

ly used process on scroll saws. It is cutting an open-

ing on the inside of the work piece without cutting

through the piece. To do this, drill a small hole that

is large enough for the blade to pass through near

the pattern line of the inside openings. Release blade

tension by flipping the cam lock handle to the blade

change position. Remove top of blade from the top

blade holder (See Blade Changing). Insert the blade

through the drilled hole in the work piece. Install the

top of the saw blade back into the top blade

holder.Retension the blade by flipping the cam lock

handle to its original position. After the cut isfinished,

remove the blade from the opening. NOTE: Discon-

nect electrical power supply before making any ad-

justments to the machine. (See Fig. 7)

FIG. 5

FIG. 4

Compound Sawing:

The compound sawing process involves cutting on

two or more sides of the work piece. To do this, sim-

ply layout a pattern on two adjoining surfaces. These

patterns may be identical or different. After the pat-

terns are laid out, choose which surface to saw first.

It usually will not make any difference which surface

you choose, but consider the sequence before

choosing. The side that will give the least amount

of scrap pieces after it is cut should be first. After

the first side is cut, return the scrap pieces to their

original locations so that you have a prismatic shape \

to cutout the second surface. It may be helpful to

nail, tape, or glue these scraps back on the piece.

(See Fig. 8)

Inlaying:

To create inlayed projects, select two pieces of

hardwood that contrast in color (walnut and oak

work well).The two must be exactly the same thick-

ness. It is recommended to use 1/4"thick material,

but any thickness up to 1 inch will work. Draw the

selected design on one of the pieces. Nail the two

pieces together with the pattern on the top face.

Be sure the nail s do not penetrate through the bot-

tom of the project as this will scratch the saw table

FIG. 7

surface. Drill a very small pilot hole (#60 drill bit) in

a corner of the pattern. Slide a #2 blade through

the drilled hole and install it in the top blade holder

FIG. 8

(be sure the pattern is still facing up). Tension the

blade and tilt the table approximately 3-1/2° (tilt the

table less for thicker material). Tilting to the left will

cause the bottom cutout to be the insert. The tilt

angle must be increased when using coarser blades.

Holding down firmly on your project, begin the cut.

Always saw in the same direction from start to fin-

ish. Saw around the pattern to the pilot hole and

remove the blade. Separate the pieces and press the

insert into the outer piece. Tap insert to set firmly.

PROCEDURE FOR

CHANGINGTHE BLADE

Step 1:

Release the Cam Over handle (HA-74) by flipping it over.

Now place the 'Lshaped quick change hold rod (HA-6S)be-

hind the upper blade holder (FA-4S)by inserting it with the

shortest end in the vertical position and the longer end fac-

ing the rear of the saw in the open hole on the top of the

upper arm. (Fig. 9) This is to help hold your upper blade

holder in a stationary position. Place the 9/64" T handle al-

Ien wrench (ES-86)into the allen head cap screw on the right

side of the upper blade holder and loosen the allen head

cap screw. Remove any pieces left of the old blade. The

blade is now ready to be removed from the lower blade

holder.

Step

Located in the V notch of the lower arm is a small, barrel

shaped blade holder (FA-46)(Fig. 10). Remove it by slidin

the blade holder forward and slightly turning towards the

front of the saw.This allows the blade to slide forward out

of the notch in the arm. When the blade is free from the

lower arm notch, slide it to the left or right to remove it

from the V notch. ow place the saw blade holder on end

in the oblong notch located on the baseof your saw.Using

a 5/16"open end wrench on the flats of the sawblade holder

(FA-46),loosen the saw blade holder and remove the old

blade. Insert the new blade (teeth pointing down) between

the two halves of the barrel of the blade holder (FA-46).Be

sure to touch the bottom of the blade to the top of the

center screw of the blade holder.

Step

You are now ready to put the blade and holder into the

V notch of the bottom arm. Holding the blade holder (FA-46)

in your hand feed the blade through the open slot in the

table top making sure the teeth are facing the front of the

saw. Slide the blade holder in front of the lower arm until

the blade will slide between the open notch in the lower

arm, Now slide the blade holder' (FA-46) back into the V

notch of the lower arm. Pull the blade tightly into the V

notch by pulling it through the hole in the table top with

the thumb and first finger of your left hand. Placethe 9/64"

T handle allen wrench

(ES-86)

into the allen head cap screw

in the upper blade holder (FA-4S)and pull down the upper

arm with pressure applied by your right hand while hold-

ing the T handle allen wrench (E5-86).Lowerthe upper blade

holder over the top end of the blade until the top of the

blade rests on the center of the allen head cap screw and

is touching the roll pin in the middle of the holder. (Fig.11)

Tighten the allen head cap screw securely with the T han-

dle allen wrench

(ES-86).

Step 4:

Remove the 9/64" T handle allen wrench and the 'Lshaped

quick change hold rod from behind the upper blade holder

assembly. Tension the blade with the Cam Over handle

(HA-74) by flipping it back to it's original position. To check

the blade tension pluck the blade like a guitar string You

should get a crisp ping sound from the blade if it is ten-

sioned correctly. If you don't receive a crisp ping, loosen

the Carn Over handle (HA-74)by flipping it back to the blade

change position and turn it like a knob, making sure the ten-

sian rod (the metal rod that holds the two arms together

at the rear) remain stationary while you turn the Carn Over.

Tighten only 1/2 turn at a time. Retension the Cam Over

by flipping it back to the original position. Check tension.
