Looking forward to using the fence
Installation instructions were good, if you take time to read them. Didn't order the side table, after 4 attempts now have a solid side table. Should have purchased years ago.....

Great Fence to own
This fence is very heavy compare to my orignal that came with my saw. I like the ease of adjustment of the fence. Just turn the inset screws and you are done.

Crème de la Crème
The Biesemeyer Commercial fence system is the gold standard of the industry and is the most highly copied table saw fence design on the market. The Biesemeyer came onto the scene in the late 70's and has steadily set the pace ever since. This simple "goof proof" and rugged design turned the woodworking industry on it's ear and changed the methods most craftsman had developed for ensuring precise cuts. The "Biese" is a true "set it and forget it" fence, that results in accurate repeatable cuts within 1/64" within seconds. Biesemeyer offers a rugged "T-Square" design that features heavy gauge steel on it's rails and guide tube. It utilizes a unique cam lever clamping system that locks down firmly on the front rail, and ensures unmatched fence parallelism repeatedly. Once the fence is initially adjusted parallel to the blade, it'll consistently lock down that way without fail. All the user needs to do is align the cursor and lock the clamping system down with single stroke.

The Biesemeyer broke the tradition of fence clamping systems that locked front and rear. The "dual lockers" are known for their firm rigidity and lack of deflection, but also for their tendency to skew from parallel due to the need to align two pivot points, as opposed to Biesemeyer's one. The Biesemeyer system is elegantly simple, and the key to it's performance is the rugged steel design. The fence "T-brace" features a 16" wide cross brace of heavy 3/16" steel that holds the fence true by clamping to the front guide tube, also made of heavy steel, that's mounted to heavy steel angle iron which mounts to predrilled holes in the cast iron table of the saw. The fence lifts readily off the table when not in use by simply releasing the cam lock. The fence itself glides on nylon pads, and parallelism is adjusted with two allen screws located on each end of the T-brace. The adjustment is very simple and only requires minor tweaking to adjust.

The Biese offers the benefit of reliable and stable settings that are easy to achieve. Deflection is minimal at the far end of the fence, 42" away from the pivot point, but is not non-existant at that point if yanked on with heavy lateral force. You may find upwards of ~ 1/8" flex at the far end if pulled hard enough, but note that the cut occurs at the front of the saw blade which is closer to 15" from the pivot point, and any amount of deflection from normal use at that point is nearly undetectable. Grabbing the end of the fence and yanking is not an accurate or realistic indicator of actual deflection of this design in use, but is unfortunately a common practice for many doubters of the design. The Biesemeyer Commercial fence is the stock fence on the famed Delta Unisaw (the long time choice of Norm Abrams), and on several of Delta's upper end hybrid or contractor saws, as well as the Craftsman 22124 hybrid saw. Every major manufacturer of cabinet saws or upper end hybrids or contractor saws offers a copy or knock-off of the original Biese design of some sort. The PM Accufence, Jet Exacta II, HTC, General T-Fence, King Industrial, Steel City industrial fence, Grizzly Shop Fox Classic, Woodtek, Canwood, etc. It's simply an elegant and effective design that's been a huge boon to average home-users and pros alike. From the first time I laid eyes and hands on this one, I knew that this is how a fence should look and feel.
