Amazing
From the first time I saw this fence I knew I wanted one. It solved all of the issues I had with my old fence and more. The ball-bearing guides are smooth and make fine adjustments so much easier than the old tap, tap, tap...damn! method I used to have to use. Installation was easy and it fit perfect on my Laguna F3. I recommend watching the installation video from Harvey. Rails and fence are well made and feel like they will hold up for years. So far it is well worth the money.
Exciting new tool
The Big Eye rip fence is in my opinion the best fence in the market. It could have better instructions but if you’re determined to, you’d figure it out. Sliding it back an forth is silky smooth. The locking handle is not longer catching your clothes or a rib. Micro adjust should be a standard on all rip fences and the built in stops simplifies replication. It has made my StopSaw which I bought with the “Premium fence” was very good to start with even better.
Simply Outstanding
I have a Laguna F2 table saw and I never liked the OEM fence. The OEM fence would always deflect slightly at the last third of the cut. The Big EYE fixes that issue and so many more. I installed it myself in about two hours. It took me another hour-ish to set the clamping forces and calibrate the squareness of the fence to my tabletop. The fence now stays under 0.1mm deviation out of square the entire length of the fence. I couldn’t ask for anything more. The Big EYE has many features that are all nice to have. I particularly like the micro-adjustment wheel. One last thing —once you put the fence where you want it, you don’t have to worry about it moving slightly while you are applying the clamping pressure. Best fence ever!
BIG EYE is AWESOME!
I just finished installing a Big Eye B-52 on my Harvey Alpha HW110TC-52P table saw. It was very straightforward and just took a few hours including removal of the original fence, the Harvey blade guard and installing the new fence. It only needed minor calibration, and it's now ready to go. The fit and finish is beautiful, and it works just as advertised. It will be fantastic to have the fence locked at front and back, especially when handling large sheet goods. Thanks Harvey, I can't wait to get cutting!
Impressive build and easy to install
Well done Harvey! I installed the Big Eye B36 on my table saw and I am impressed. Packaging was bomb proof and assembly instructions were easy to follow. After calibrating blade and fence I had less than .002 run out from front to rear of the fence. Nicest part is the thumbwheel that makes fine adjustments very easy. No more tapping and realigning for adjustments. Once you have the desired measurement, effortlessly lock down the fence with “zero” movement. This fence system and the included fence stops are accurate, unobtrusive, and well worth the price. Bonus, the included two clamps for an out feed table fit perfectly with my dust extraction system and I did not have to mill new pieces. I am still working on incorporating my existing out feed table but I do not anticipate any issues. I am using roller lifts in the interim. I especially like the compatibility of this fence system with non Harvey table saws. Harvey engineering team hit a home run with this design.
great machine
Harvey really nailed the engineering and design of the big eye rip fence. It is easy to install, calibrate, and operate. Cutting on both sides of the blade is a big advantage that many woodworkers don't appreciate until they have it. The precision and repeatability are of the highest quality. If you are in the market for a rip fence this is the one to buy.
Best Fence in the industry!
The quality of this fence is head and shoulders above anything else I have ever been around. I've been doing woodworking for 20 years and this is the highest quality fence out there. A fantastic company to deal with in every way! I will be adding more of their equipment to my operation in the future.
Worth the wait in gold!
Just got it installed and ran it though a bunch of tests, this fence is phenomenal, truly nothing else like it, Harvey hit on all notes with this one, installation, adjustability, easy of use, super accurate, very appealing to look at and is filled with tons of features. I would give 10 stars if I could.
An unprecedented rip-cutting solution for table saws
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 Rail 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!

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.
The steel rods undergo surface hardening, ensuring long-term durability even with extended use.
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.
Dual-end Clamping controlled by the linkage mechanism
Front end clamping mechanism
Rear end clamping 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 accuracy of fence position remains within 0.02mm (0.0008”).
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 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 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 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.
*K9 glass is a crystalline form of silica and falls into the category of optical glass. It is renowned for its exceptional transparency, and the products crafted from it are referred to as crystal glass artifacts. It finds extensive applications in various fields, particularly in optical coating.

Customer Reviews
This thing is so smooth! Unreal how well built it is!
Well build, well designed, prompt shipping. Havent had enough use to give further critique.
Awesome fence
This fence is extremely well built. It was accurate and required no adjustments for the alignment. I installed this fence on a SawStop Industrial model. I did have to drill all new holes as the SawStop's holes are at 22mm below the top surface and the Harvey fence needs it to be a minimum of 26mm. This was a small issue that require drilling holes in the table top accurately. It is very solid and moves freely. I am pleased as punch about this fence. For me it is well worth the money to get this accuracy. I could not notice any deflection with this fence. I look forward to years of fun ripping.
Was not wanting to pay up but so glad I did. This fence is amazingly accurate. Put it on a ridgid saw and it fit perfectly with very lil modification.
I have been in the woodworking world for 30 years used different fence systems the one I settled on was Biesmeyer which is a very good fence system but when I installed the Big Eye 52” on my new Alpha HW 110 TC pro. I had no idea of what a true professional fence system was like this is no nonsense the best most accurate system I’ve ever used. The solid locking front and back is a woodworkers dream. The smooth non binding movement is something I did not think could happen but Harvey did it ! Also the stops on the fence is genius.
Great job Harvey!
Great fence extremely accurate fence with my age "76" it was difficult to read my old shop fox fence this fence is easy to read and adjust worth every penny great fence
Super sturdy and fits the table saw perfectly.
