INSTRUCTIONS FOR G2320 AND G2606

MOULDING HEAD

•Failure to follow these guide-

lines will result in serious

personal injury.

•ALWAYS WEAR ANSI

APPROVED EYE AND EAR

PROTECTION when using

this cutter.

•Never use on 1⁄2" spindle.

•Never operate with only one

moulding knife installed.

•Never feed lumber with the

rotation of the cutter.

•Follow the safety guidelines

set forth by the manufac-

turer of the shaper.

The moulding cutters have

sharp edges. Use care while

removing them from the

package. The oily film must

be removed from the knives

before installation to help

insure secured assembly.

The 2-knife moulding head is designed to be used on a vertical spindle shaper. It is made of the highest quality aircraft aluminum and machined to exact tolerances. The moulding head accepts matched pairs of interchangeable corrugated backed High Speed knives (not included). The moulding head will use either 60˚ or 90˚ cut corrugations that are spaced

⁄16" apart. The knives lock into position by wedge-type gibs for

maximum safety.

Do not use this moulding head on any machine other than one equipped with a

1" spindle for the G2606. The shaper should have at least a 1

⁄2 H.P. motor. We also recommend the use of

⁄4" spindle for the G2320 or

a power feeder when using this moulding head.

NOTE: These instructions and drawings are intended for explanation and clarification purposes only as they pertain to the moulding head. You must apply all safety measures as they relate to shaping operations and your specific equipment. Review and apply all safety measures before you use this moulding head.

STEP 1 — INSTALLING THE FIRST KNIFE

• Unplug shaper be fo re in st al l-

in g or adjusting cutter.

• Keep all guards and anti-kick-

back devices in place.

• Double check cutterhead to

insure it is tight an d secure

in spindle.

• Always inspect lumber and other

wood materials for cracks, knots,

or other imperfections that could

cause lumber to kick or shatter

while shaping .

1. Hold a gib in the moulding head and slide the knife into place along the corrugations. Make sure all of the corrugations in the moulding head engage the knife. See illustration to the

right.

2. Slide the knife into the moulding head

until it is centered along the body of the cutterhead.

3. While holding the position of the knife and gib in the moulding head, tighten

the gib with a

/16" Allen® wrench. Do not over-tighten the setscrews. Use only enough force to secure the knife snugly in position.

STEP 2 —INSTALLING THE SECOND KNIFE

1. Insert the second knife in the moulding head as in Step 1.

2. Take care to match the number of corrugations which are engaged on the

second knife so it is the same position as the first knife. This will ensure that both knives will be set to the same height.

3. Do not completely secure knife at this time. Tighten gib so the knife is held in position. Proceed to next step.

STEP 3 — KNIFE ADJUSTMENT

Match

engagement.

Make sure both knives are held

securely in position. Recheck all

adjustments and tightening sequenc-

es. Failure to do so may create a

serious safety hazard.

Disconnect electrical power from shaper. Install

cutterhead onto spindle and fasten as detailed in the shaper’s manual. Choose a reference point on the first

knife installed and adjust spindle height until this point is even with table top. (The reference point can be the bottom corner of the knife

or any feature that allows vertical alignment with the table top).

Adjust the second knife up or down until the corresponding point is at the same height with respect to the table. Now snug up the second gib. At this time, tighten all the setscrews in both gibs. Tighten each setscrew a small amount, then move to the next setscrew until they all are tight. Do not over-tighten gib

screws.

SPINDLE MOUNTING TIPS

• Mount the moulding head as low as possible on the spindle.

• Add a spacer(s) on top of cutterhead to ensure that the spindle nut does not rest on the cutterhead shoul der.

• Secure the assembly with a locking washer and nut or two nuts locked together.

• Ensure that your shaper is in tip-top running condition and that all guards are in place.

GENERAL PROCEDURES

The wide selection of knife profiles make the moulding head a versatile addition to your shaper. The moulding head operates on the same principle as other shaper cutters and can be used for straight edge shaping as well as irregular shaping. Since the moulding head is larger in diameter than most cutters, it must be oper ated at speeds ranging between 4,000 to 7,000 RPM. Please refer to your shaper’s manual if you are unsure about operating speeds.

Always feed stock against rotation. Cutterhead must come to a complete stop and

the shaper must be disconnect from power supply before making inspections or adjustments.

Remember, when setting up for either straight edge or irregular edge shaping, the electrical power must be disconnected. For straight edge shaping use the fence assembly. See fence adjustment section in the shaper’s manual to align fences. All guards must be in position and functioning correctly.

1. Select the appropriate knife profile and lock into moulding head

(See Page 1). Secure moulding head onto spindle.

2. Check rotation. Be sure moulding head is rotating in the desired

direction and that the knives are oriented correctly. See illustra

tion at right.

4. Position the outfeed fence for depth of cut.

5. Use hold-downs, jigs or anti-kickback devices to secure workpiece during the shaping operation. See the

shaper’s manual for particular safety information regarding this shaping operation.

6. Always make a sample cut on a piece of scrap wood before shaping workpiece. Readjust if necessary.

7. Follow recommended operating procedures for shaping end of stock. See the shaper’s manual for par-

ticular safety information regarding this shaping operation.

Make sure cutterhead comes to a complete stop and the power is disconnected before making any inspections or adjustments.

IRREGULAR SHAPING

Irregular shaping (freehand) takes a high degree of skill and manual dexterity to perform. The fence assembly is not used in irregular shaping and should be removed. Rub collars must be used. Choose the correct diameter for the

appropriate depth of cut. When doing freehand work, a starting pin must be used. The purpose of the starting pin is to support the work piece. The start ing pin acts as a pivot point and gives the operator more control during the beginning of the cut.

Rub collars can be positioned on top or below the moulding head, depending on the type of work. Plan ahead and determine which rub collar position will

work best for your particular needs.

6. Insert guide pin into table surface; choose appropriate hole posi-

tion. See owner’s manual for loca

tion. If a starting pin is not available, use a starting block.

•Always use a starting pin/block

and rub collar for freehand work.

•Use guards and hold-downs.

•Follow the safety guidelines set

forth by the manufacturer of the

shaper.

7. Inspect stock or pattern for any

irregularities which may cause a miss-cut.

8. Use some type of hold-down(s), fixtures and guards when performing freehand work.

9. The workpiece should be placed in the starting position (1) using the guide pin for support, as shown below. Gradually swing the work into the cutter keeping the work piece against the starting pin (

10. After the workpiece is supported by the rub collar, swing the work free of the starting pin (3). Always feed

against the rotation of the cutter.

11. Always make a sample cut on a piece of scrap wood. Readjust if necessary.

Make sure cutterhead comes to a complete stop and the power is disconnected before making any inspections or adjustments.
