A high quality rip fence is essential for a table saw to achieve desirable cutting precision and safety. The most popular table saw rip fence in the market has been the “T-square” style design and it has been around for many decades. The “T-square” rip fence is generally working fine for the purpose, but obviously it is far from being ideal in terms of positioning accuracy, repeatability, and ease of operations. Woodworkers normally need to make several “trial & error” cuts before reaching a satisfactory precision due to the sloppy fence rail guiding, fence body deflection (cantilever), and structural displacement by locking force. The whole fence system is simply not rigid and stable.

With these issues in mind for long time, the Harvey team has been committed to design a completely new rip fence system for woodworkers to address the above problems. Now we are excited to announce our brand new development: The BIG EYE™ Rip Fence System!

The BIG EYE Rip Fence System (Patent Pending) revolutionizes rip cutting positioning with two major break-through structural designs: The Dual-axis Linear Guide System, and the Synchronized Dual-end Fence Locking Mechanism. The Linear Guide enables the fence glide on rails smoothly with Zero clearance and minimal friction, also it makes the fence gliding motion accuracy within astonishing 0.15mm (0.006”) throughout the full rail length. The Synchronized Dual-end Locking Mechanism allows for “Single Action” to lock the both ends of the fence which literally eliminate the deflective drifting of the fence body during cutting. These two major innovative designs dramatically create the exceptional rip cutting precision and repetition reliability.

Like other Harvey products, every part of the BIG EYE Rip Fence System is precision machined or ground from aircraft aluminum alloy, hardened steel or stainless steel. Every detail of the BIG EYE Rip Fence is dedicatedly designed and crafted for the best experience of users functionally and aesthetically. We truly believe the BIG EYE Rip Fence System will greatly improve your table saw cutting performance, working experience and the joy of woodworking!

The Dual-axis Linear Guide Rail System

At the core of the Big Eye Rip Fence System lies the Dual-axis Linear Guide Rail System, featuring eight rollers with bearings that effortlessly glide along the two hardened and ground steel rods with zero clearance. This innovative design replaces traditional bushing sliding friction with smooth rolling friction, resulting in exceptional accurate fence movement (0.15mm in full length). The system includes four fixed bearings and four adjustable bearings, eliminating gaps between the bearings and steel rods, thus maintaining parallelism between the fence and the saw blade and enabling clearance free gliding motion. To enhance the security of the fence during gliding, the guide rail ends are equipped with flip stops that can be easily moved out of the way, allowing effortless removal of the fence from either end of the guide rail as needed. The Sealing covers and felt on the sliding bases effectively minimize dust interference, ensuring smooth operation even in dusty environments.

The Synchronized Dual-end Fence Locking Mechanism

The innovative Synchronized Dual-end Fence Locking Mechanism enables simultaneous clamping of the fence on to the solid front and rear guide rail bodies. The synchronized dual-end clamping mechanism allows for “Single Action” locking, and prevents the fence from deflective drifts during cutting. With the fence locked in place, the accuracy of the fence position remains within 0.02mm (0.0008”!).

The Synchronized Dual-end Fence Locking mechanism allows for the fence's load capacity up to 300N, effectively preventing any displacement of the fence during cutting and ensuring safety. The Polished Stainless Steel Locking/Release Handle is uniquely installed on the top of the fence for intuitive and user-friendly operations. Compared to the traditional lower-mounted locking level, the BIG EYE Handle will eliminate the risk of user’s leg injuries by level collisions during work.

The Independent Clamping Force Adjustments

The BIG EYE Rip Fence System is designed to allow for independent adjustments of the clamping force at both ends of the fence using easy adjustment knobs.

The Versatile Fence Positions:

The BIG EYE Rip Fence System features a standard high/low fence plate to accommodate different wood thicknesses. The high fence is designed for cutting thick wood, while the low fence is suitable for thin wood. Switching between the two fence positions is effortless with the sliding scale. The fence plate can be installed on either left or right side of the fence body, facilitating usage on both sides of the saw blade. Additionally, the fence plate can be conveniently slid to the front of the saw blade, providing cross-cut positioning without the risk of kickback.

The Micro Adjustment, Fence Flip Stops and the K9 Glass Viewers

The BIG EYE Rip Fence System also features a Micro-adjustment knob for extremely fine fence positioning with ease. The knob is designed to be a intuitive hand roller.

To achieve your streamline repetitive cutting tasks of various sizes, the BIG EYE Rip Fence System comes with four (4) built-in Flip Position Stops for your quick and comfortable operations.

In order to make the position reading much more comfortable and easy, the BIG EYE Rip Fence System introduces a very special scale viewer: The K9 Crystal Glass Window. The K9-grade glass boasts an impressive light transmittance of up to 92% and exceptional hardness, ensures minimal visual errors (parallax) when reading measurements, offering superior durability and resistance to wear. The fence is equipped with scales in both metric and imperial units, providing measurement flexibility. The imperial ruler offers a resolution of 1/32", while the metric ruler achieves a resolution of 1mm.

The Universal Installation:

The BIG EYE Rip Fence System is designed with a special Slot-Style Installation, which slides the guide rail onto the bolts installed in the side of cast iron work tables for easy mounting on a wide range of table saws. The system is compatible with table saws with depth ranging from 685mm (27”) to 800mm (31-1/2”).

The BIG EYE Rip Fence has two models: B-52 and B-36 to fit for your 36" or 52" rail lengths.

The BIG EYE Rip Fence System is compatible with the most renowned table saw brands such as SawStop, Powermatic, JET, Laguna Grizzly, and more (Cast iron worktable is required).

The Building Materials:

The BIG EYE Rip Fence System is predominantly crafted from anodized aircraft grade aluminum alloys, hardened steel, and stainless steel, all parts are CNC machined or ground, offering excellent corrosion and wear resistance, ensuring longevity and aesthetically pleasing appearance.
