The primary difference is body thickness and maximum stock capacity:

COMPASS RG-1: 1" body thickness, handles stock up to 2" thick, weighs 4.2 lbs

COMPASS RG-2: 2" body thickness, handles stock up to 4" thick, weighs 5.5 lbs

Both models share identical roller systems, pressure ranges, and mounting mechanisms. Choose RG-1 for typical cabinet making and furniture work with thinner stock, or RG-2 for heavy timber work and thicker stock applications.

Yes, the COMPASS Universal Roller Guide provides superior performance compared to traditional featherboards. The dual roller system offers smooth feeding with reduced friction, while the Independent Suspension Mechanism (ISM) provides even pressure that featherboards cannot match. The one-way bearings offer significantly better kickback prevention than featherboard fingers.

Each of the two rollers is fitted with an independent pre-loaded spring system. This allows each roller to move independently, adapting to slight variations in workpiece surface height or flatness. Unlike fixed featherboards that create uneven pressure points, the ISM maintains consistent holding force across the entire workpiece, eliminating chatter and improving cut quality.

The COMPASS Universal Roller Guide provides adjustable holding force from 15-22 lbs (70-100N). Adjustment is tool-free using the self-locking cam knob. Start at the zero position, then rotate the knob clockwise or counter-clockwise to increase pressure. The cam mechanism locks automatically, maintaining your set pressure throughout the cut.

The COMPASS Universal Roller Guide is compatible with any woodworking machine equipped with standard 3/4" x 3/8" x 1" T-slots, including:

- Table saws (all brands with compatible T-slots)

- Band saws with table-mounted T-slots

- Router tables with T-slot systems

- Wood shapers with compatible mounting surfaces

This includes Harvey's Alpha and Ambassador series, as well as SawStop, Powermatic, Delta, Jet, Grizzly, and most other professional woodworking machines.

Installation is tool-free and takes 5-10 minutes:

1. Loosen both locking knobs on the unit

2. Turn adjustment knob to zero "0" position

3. Insert T-block into your table's T-slot

4. Position workpiece against fence

5. Push roller guide toward workpiece until rollers contact surface

6. Tighten both locking knobs to secure position

7. Rotate adjustment knob to apply desired pressure

8. Test by gently pushing workpiece to verify secure hold

Detailed instructions with diagrams are included in the owner's manual.

Vertical orientation is possible but requires modifications. The standard design is optimized for horizontal mounting on table surfaces. For vertical applications on wood shapers or other machines, custom mounting adapters may be necessary. Contact Harvey Woodworking technical support for specific vertical mounting guidance.

Yes, the Independent Suspension Mechanism (ISM) is specifically designed to handle workpieces with slightly uneven surfaces. Each roller adjusts independently to maintain even pressure despite surface variations. However, extremely rough or warped stock should be jointed or planed before cutting for best results and safety.

The COMPASS Universal Roller Guide features a directional arrow on the body indicating proper feed direction. This arrow must align with your workpiece feed direction. If the arrow points the wrong way, flip the entire unit over and reinstall. The one-way bearings only allow rotation in the feed direction for kickback prevention.

One-way roller bearings (CSK10PP type) provide significantly higher reverse resistance, preventing the rollers from spinning backward if the workpiece starts to kick back. This creates a mechanical safety barrier that standard bearings cannot provide, making cuts substantially safer than featherboard systems.

Adjust pressure based on material density and workpiece characteristics:

- Softwoods (pine, cedar, fir): 15-17 lbs (70-80N) - light pressure

- Hardwoods (oak, maple, walnut): 18-20 lbs (85-95N) - medium pressure

- Dense hardwoods (purpleheart, ebony, rosewood): 20-22 lbs (95-100N) - maximum pressure

- Thin stock (under 1/2"): Lower pressure to prevent deflection

- Thick stock (over 2"): Higher pressure for stability

Start with lower pressure and increase gradually until workpiece is secure but feeds smoothly.

Yes, using two COMPASS Universal Roller Guides provides enhanced workpiece control, especially for longer stock or wider cuts. Position one guide near the cutting area and another further back along the feed path. Ensure both units are set to similar pressure levels for balanced support.

The 6-1/2" roller travel distance allows the guide to maintain contact with the workpiece across a wide range of positions relative to the cutting tool. This extensive travel range means you can position the guide optimally for different fence positions and workpiece widths without needing to remount the unit.

The COMPASS Universal Roller Guide requires minimal maintenance:

Daily: Check roller rotation and remove dust buildup

Weekly: Inspect polyurethane tires for damage and verify locking knob tightness

Monthly: Lubricate moving parts and check bearing function

Annual: Professional inspection for high-use applications

The anodized aluminum construction and sealed bearings provide long-term durability with basic care.

 For resin or pitch accumulation on polyurethane rollers:

1. Disconnect power from machine

2. Apply mineral spirits or dedicated pitch remover to soft cloth

3. Wipe roller surfaces while rotating by hand

4. Remove residue with clean, dry cloth

5. Verify smooth rotation before resuming use

Avoid harsh solvents that may damage polyurethane material.

With normal use, polyurethane roller tires typically last 3-5 years before replacement is needed. High-volume production environments may require earlier replacement. Replace tires if you notice:

- Visible cuts or tears in material

- Flat spots from prolonged pressure

- Reduced grip effectiveness

- Uneven wear patterns

The COMPASS Universal Roller Guide enhances safety but does not replace standard safety equipment:

- Safety glasses for eye protection

- Push sticks or push blocks for maintaining hand distance

- Hearing protection for extended operations

- Dust collection system for respiratory safety

- Blade guards where applicable

Always maintain 6" minimum hand distance from cutting areas.

While the one-way roller bearing system provides excellent kickback resistance, no device can prevent 100% of kickback incidents. The COMPASS Universal Roller Guide significantly reduces kickback risk but must be used in conjunction with:

- Proper fence alignment

- Sharp cutting tools

- Appropriate feed rates

- Correct blade height

- Proper workpiece support

Always follow comprehensive safety procedures for your specific machine.

Minimum workpiece length should be at least 12" for safe operation with the COMPASS Universal Roller Guide. This provides sufficient material length for:

- Proper positioning against fence

- Secure contact with both rollers

- Safe hand placement distance from cutting area

- Stable feed throughout cut

Shorter pieces require specialized jigs or fixtures for safe processing.

To verify correct pressure:

1. Set initial pressure using adjustment knob

2. Gently push workpiece by hand - it should resist movement but not be locked

3. Workpiece should feed smoothly without excessive force

4. Check that workpiece maintains firm contact with fence throughout travel

5. If workpiece deflects or lifts from table, reduce pressure

6. If workpiece slides too easily, increase pressure

Perfect pressure allows controlled feed while preventing kickback.

Workpiece chatter typically indicates:

- Insufficient holding pressure - increase adjustment

- Uneven workpiece surface - joint or plane stock before cutting

- Worn or damaged rollers - inspect and replace if necessary

- Loose locking knobs - verify both knobs are fully tightened

- Dull cutting tool - sharpen or replace blade/bit

- Excessive feed rate - slow down feed speed

The ISM system specifically addresses chatter, so persistent vibration suggests one of these correctable issues.

The COMPASS Universal Roller Guide offers several advantages over traditional featherboards:

Superior Features:

- Rolling contact vs. sliding friction for smoother feeding

- Independent Suspension Mechanism providing even pressure on uneven surfaces

- One-way bearings offering better kickback prevention

- Infinite pressure adjustment vs. fixed tension

- Tool-free setup and adjustment

- Higher pressure range (15-22 lbs) with precise control

- More durable construction with longer service life

Featherboards remain useful for certain applications but the roller guide system represents a significant technological advancement in workpiece control.

Yes, the COMPASS Universal Roller Guide is fully compatible with riving knives, splitters, and overhead blade guards. The guide mounts to the table surface T-slot and does not interfere with overhead safety equipment. Position the guide to provide support without obstructing the riving knife path.

The COMPASS Universal Roller Guide is primarily designed for rip cutting operations where the workpiece feeds along the fence. For crosscut operations with a miter gauge or sled, the guide is typically not needed as the sled provides workpiece control. However, it can assist with certain angled cuts or pattern work on router tables.
