Drilling & Tapping Installation Holes

Older Model G1140 Edge Sanders does not come with the installation holes shown in Figure 2. These models will have to be drilled and tapped as described in the following instructions.

To drill and tap the installation holes:

1. Unplug the sander!

2. If you are installing the radius attachment onto a Model G1140 Edge Sander, remove the end table, main table, table adjustment mechanisms, and the sanding stop.

3. Use a center punch to mark the installation holes shown in Figures 3 & 4.

4. Temporarily bolt the long support bracket into the two holes indicated in Figure 5 and use a center punch to mark the location of the third hole.

5. Drill pilot holes with an ¹⁄8″ or a ³⁄16″ drill bit.

6. Drill the holes through the platen and the rotation plate with a 7⁄16″ drill bit.

7. Drill the installation hole in the stand using a 5⁄16″ drill bit.
   Note —Always use cutting fluid when drilling and tapping sheet metal (the stand and rotation plate). When drilling or tapping cast iron (the platen), cutting fluid is not necessary.

8. Thread the stand installation hole with a 3⁄8″ tap.
   Note— For every half turn of the tap, back off a quarter turn to clear the chips and prevent the tap from breaking.

Assembly

To install fretboard radius attachment:

1. Slide the slot in the short support bracket onto the rotation plate and loosely attach the bracket to the platen with two 3⁄8″-16 x 2″ hex bolts, four flat washers, and two hex nuts. Note—Some machines may require the included 3⁄8″ thick shim between the bracket and the platen.
2. Attach the rotation plate bracket to the short support bracket with (2) 5⁄16″-18 x 1⁄2″ hex bolts and (2) 5⁄16″ flat washers (see Figure 6), then align the hole in short support bracket with a hole in rotation plate and loosely secure it with a 3⁄8″-16 x 1½” hex bolt and a 3⁄8″ flat washer.
3. Plumb the short support bracket as shown in Figure 7 and tighten the bolts.
4. Install the long support bracket with three 3⁄8″-16 x 1″ hex bolts and washers.
5. Plumb the long support bracket and tighten the bolts.
6. Remove the upper right motor mounting bolt.
7. Install the cross brace as shown in Figure 8 with three 5⁄16″-18 x 2½” hex bolts, six flat washers, and three hex nuts.
8. Slide the horizontal adjustment tubes through the guide rails as shown in Figure 9, with the threaded holes towards the outside of the machine, and tighten the hex bolts.
9. Slide the height adjustment arms into the locking plates, as shown in Figure 10, with the hanger openings outward, and tighten the hex bolts.
10. Place the swing arm into the hanger openings as shown in Figure 11.
11. Adjust the height adjustment arms until the swing arm is seated into the hangers and both ends are an equal distance above the sanding belt.
12. To use the full surface of the sanding belt, slide the horizontal adjustment arms so the swing arm is diagonal across the sanding belt surface.

OPERATIONS

Operation Safety

Warning: Damage to your eyes, lungs, and ears could result from using this attachment without proper protective gear. Always wear safety glasses, a respirator, and hearing protection when operating this attachment.

Warning : Loose hair and clothing could get caught in machinery and cause serious personal injury. Keep loose clothing and long hair away from moving machinery.

NOTICE
If you have never used this type of attachment or equipment before, WE STRONGLY RECOMMEND that you read books, trade magazines, or get formal training before beginning any projects. Regardless of the content in this section, Grizzly Industrial will not be held liable for accidents caused by lack of training.

Attaching the Fretboard

There are several methods of attaching the fretboard to the radius attachment. These include screws, double stick tape, friction pins, clamping, or a vacuum system. These instruc-tions only cover attaching the fretboard with double- stick tape.
To attach the fretboard to the radius attachment:

1. Use a jointer to flatten the back of the fretboard.

2. Mark a line down the center of the back of the fretboard.
   Note —This centerline is important. If it is off-center, the radius of the fretboard will be off-center.

3. Place a strip of double-stick tape on either side of the holes in the swing arm crossbar. Note—Only use high-quality, film type, double stick tape. Reinforced and foam-backed double stick tape will not hold the fretboard securely.

4. Line up the swing arm crossbar holes with the centerline on the fretboard and carefully stick the fretboard to the crossbar.

5. When finished radiating the fretboard, remove the tape residue from the crossbar with WD-40®, or an oil, such as gun oil.

6. Clean off the oil residue with lacquer thinner or an alcohol-based solvent.

Adjusting Radius

This fretboard radius attachment is capable of creating radiuses from 10″ to 16″ by adjusting the distance from the swing arm shaft to the sanded surface.

To adjust the radius:

1. Loosen the button head cap screws that secure the swing arm shafts to the height adjustable arms as shown in Figure 12.

2. Adjust the height from the bottom surface of the fretboard to the center of the swing arm shaft to the desired radius.
   Example: To achieve a 16″ radius on the fretboard, the distance is shown as X” in Figure 12 would be 16″.

3. Repeat Step 2 on the other end of the fretboard.
   Note —To create a compound radius, the distance from the fretboard to the swing arm shaft will be different on each end.

Sanding

To radius a fretboard:

1. Adjust the height adjustment arm so the cross member is parallel with the sanding belt as shown in Figure 13.
   Note —Notice how the swing arm shafts in Figure 13 are different distances from the fretboard (to create a compound radius), but the fretboard is parallel with the sanding belt.

2. Use the leveling knobs to fine-tune the height so the swing arm can have free motion.

3. Turn the sander ON. Lower the fretboard with the leveling knobs and swing the swingarm. Continue with this step until the fretboard is sanded across its entire surface.

4. Check the fretboard for the desired radius with radius gauges.

5. If the radius is incorrect, increase the distance between the swing arm shaft and the fretboard to make a larger radius; shorten it to make a smaller radius.

6. If the radius is correct, continue sanding the fretboard to the desired thickness.

MAINTENANCE

Lubrication

This radiusing attachment requires minimal main-tenance. For optimum performance, lubricate the swing arm shafts with a general-purpose grease, as needed.

Cleaning

Cleaning the Model G0577 is relatively easy. Vacuum excess wood chips and sawdust, and wipe off the remaining dust with a dry cloth.

Warning: Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury.
