Smooth Gliding Fence Offers Multiple Stops
Additionally, the fence glides smoothly throughout its complete range of motion and tilts both ways with the traditional stops at 45 and 90 degrees to handle bevel operations. This also allows you to quickly reproduce multiple cuts at any angle.

Steel Knife Cutter Head for Speed; Cast-Iron Table for Accuracy
One of the most innovative aspects of the JJ-6CSX's design is the triple-bladed, high-speed steel knife cutter head, which delivers rapid cutting and a superior finish for high-quality results. The blades are part of an exclusive auto-set quick-change knife system, which allows you to replace or change all three blades in a fraction of the time other machines take.

The jointer also features a cast-iron table with a precision-machined finish, so you can count on the accuracy of each pass.

Powerful 1 HP Motor and Rabbeting Ledge for Versatility
Equipped with a powerful 1 HP motor, the JJ-6CSX easily handles a wide range of jobs. A built-in rabbeting ledge also lends versatility, while a heavy-duty, one-piece steel closed stand includes mounting tabs for increased stability, so you can easily handle different wood types and sizes.

User-Friendly Controls and Features
Designed to be extremely user-friendly, the JJ-6CSX features industrial push-button controls conveniently placed throughout for easy access. In addition, the center fence controls are conveniently mounted to allow quick adjustments, and a built-in dust chute with four-inch port quickly connects to your collection system for efficient dust and chip disposal.

About JET: A History of Sharing New, Feature-Rich Products
Opened in 1958 after the founder of the company, Leslie P. Sussman, took the first Boeing Jet Airplane trip from Seattle, Washington to Japan, JET began as a small dealer that sold air hoists and trolleys out of a single hardware store in Seattle. Over the years, JET has carried everything from snowmobiles, transmitter radios, and forklifts to nylon stockings, but by the early 1970s, metalworking had become the base of their business line. And by the 1980s, JET had expanded into the realm of woodworking. Today, you'll find that JET offers a wide range of popular woodworking tools that are backed with best-in-class features and excellent service.

What's in the Box
One stand with motor, one stand cover with mounting hardware, one dust chute with mounting hardware, one 12/14-millimeter open end wrench, one 8/10-millimeter open end wrench, one 3-millimeter hex wrench, one bed assembly, one fence assembly, one cutterhead guard, one belt guard, one V-belt, four 1/4-20 x 1/2 pan head screws, four 1/4 flat washers, one lock handle, flat washer, and lock nut for the fence, one fence handle, three lock bolts, 3-3/8-inch lock washers, two handwheel assembly, one can of touch-up paint, manual, warranty card, and two push blocks.

This jointer replaced a very old Delta which had handwheels located under the tables. I liked the Jet because the handwheels are located in front of the tables. Some people find that adjustment levers work best for them, but I have always prefered handwheels because its easier for me to make small adjustments.

The unit arrived in excellent condition. There were no scratches, dents or missing parts -great job Jet! It was packaged in two boxes with the contents of each identified on the outside of the boxes. By the way, the instruction manual is located in the (larger) box that contains the jointer table and various other parts. The smaller box contains the base, and the base door. Everything is tightly packed in styro containers and wrapped in plastic bags. Jet even packs a small can of paint, two wrenches and an allen wrench to adjust the cutters (however, mine were set perfectly at the factory). The instruction manual is well written and has good picture references.

I put the unit on a shopmade mobile base that I made and had used sucessfully with the Delta jointer. I like it because it lifts the unit up about 2" and does not slip when you apply pressure or work with heavy wood. (I found the plans in a "Shop Notes" magazine a couple of years ago).

The unit went together with no hitches. The fit and finish is great. Everything lined up perfectly. The back fence was set correctly at the factory to stop at 90 & 45 degrees, so no correction was needed. I installed the belt, dust chute and belt guard and went through the steps to set up the infeed and outfeed tables. The outfeed table also was already adjusted correctly and this saved a lot of time. After that I ran several soft and hardwood boards through and was very pleased with the results. The units 1 HP TEFC motor ran remarkably quiet and the cuts were very smooth. The dust collection chute also worked fine with my shop system.

I would highly recommend this unit if you are in the market for a good, easy to set up and operate 6" jointer. Happy woodworking!

Picked one up a couple months ago.

Everything was right on. Assembled it according to the instructions and it cut like a dream. I tested it out with some scraps of oak I got at my wood supplier. Great finish and perfectly straight after running them through a couple times.

Machine has little vibration. Not too loud. Plenty of power.

Like every machine that has the typical 'fan belt', the vibration can be reduced with a link belt, along with a reduction in noise. Hearing protection is a must with any wood cutting operation, just as important as safety glasses.

I went a long time without a jointer and have greatly increased the quality of my work with it. If you are looking to add a nice piece of equipment to your shop to help you produce better results, I would recommend this jointer.

This machine has all the right features. First thing to do is coat the fence and table surfaces with Slip-It or a non-silicon wax. It's a night and day difference when the wood easily glides across the table and when you have to force it.

For a 6" jointer it was the Jet or the Delta. For me, the Jet had the edge with the hand crank adjustment of the infeed and outfeed tables.

Update: Did some rabbiting cuts with it and it worked great. Seemed alot easier and safer than using a router. Finish on the cuts was excellent. Hogged out about 1/4" in a single pass in hard maple with no problem.

Hope this helped.


We gave Jet another try....   February 19, 2003

We operate the Jet 6" jointer in our wood shop and we have found it to be a solid tool for the last 9 months. It replaced a craftsman unit from the 50's. Reading some of the reviews, it seems Jet is still suffering from a boonedoggle from a few years ago with a poor decision to keep up with demand for their large machines. They decided to use what is called "green" castings so that they could keep up production of their equipment to meet demand. "Green" means they used castings that weren't left to rest for about a year and instead used castings that were probably 2 to 4 months old. Being green the metal internally shifts. They ground these to tolerances, built up the machines and shipped them out. Then the consumer got it and found that the tables, fences etc. were twisted, warped and out of tolerance due to the metal shifting to its final position. We learned about this with a Jet cabinet saw bought 3 years ago. we had the table ground to spec twice in the first year! [(it was so bad the fence would bind!) Out with the Jet and in came another Delta Unisaw.]
This jointer has served us well and we really can't find any
real flaw with it except that the in-feed / out-feed tables are short for handling longer boards, we modified ours to extend our In/out-feed tables to help handle this problem when we run long boards which isn't often. We choose this unit over the Delta due to the "twist" adjustments instead of the handles on the Delta. The setup was fairly simple but we did spend some time getting it all aligned, we use a dail indicator to get all our tools dead perfect. So far the machine has maintained the accuracy of our set-up. Very important! The fit and finish is very nice. The blades are decent but we now use Freud blades with better run times between sharpening. Also watch out if you decide to go with a used Jet, chances are it is being sold due to being warped and twisted. So if you choose Jet equipment stay with new - our cabinet saw is out there somewhere.


Great Jointer for a Small Shop   September 12, 2003

I've had this jointer for more than five years now. It's a fantastic tool--my favorite in the shop.

Setup was a breeze--this was the first power tool I've had to set up on my own. Other than a little help from my wife to lift the jointer onto the closed base, I was able to assemble and tune the Jet by myself in less than an hour. The tuning was just about effortless, as everything was tuned within spec right out of the box. I refined a couple of things (blade adjustment and outfeed table-to-blade alignment), but those were the only adjustments, and wouldn't strictly have been necessary.

The Jet is very quiet compared with other jointers I've used--in fact, when my dust collector is running you can't tell the jointer is even switched on.

The Jet has plenty of power to cut thru just about anything. I regularly take up to 1/16" off of 3/4 to 3" stock in both hard and softwoods, and the jointer plows thru this all without breaking a sweat. I have used it to take off as much as 3/16" (not that I would recommend this with any jointer). I've done a little planing of hardwood and softwood boards up to 5 1/2" wide. The Jet does a great job of planing, but (as with any jointer, I would expect) you must feed properly to ensure you take off the same amount across the face of the board. I generally prefer a thickness planer for this task. I have not used it for rabbeting.

The front-mounted handwheels are blindingly simple to use, and very smooth. I much prefer them to the Delta 37-190's lever-adjust system as it's easier to make fine-increment changes. The only gripe I have about adjusting the tables is the 1/8" safety lockout mounted at the back of the jointer. You must loosen two knobs, then pull the lockout while you turn the handwheel if you expect to take more than 1/8" in a pass, or make rabbets. This isn't a problem, per se, but you must be careful not to accidentally force the handwheel when the lock kicks in or you'll damage the table mechanism.

The fence is very easy to use. It slides manually, but it moves very smoothly on machined surfaces, making it simple to adjust the width of the exposed blade. The angle is also simple to adjust. Occasionally the fence grab lever/knob will catch your knuckles while jointing pieces that are around 6" wide (especially when beveling), so I remove and reinstall the lever as necessary. The fence has stops for 45 degrees and 90 degrees, so making bevels is a simple setup. The 45 degree stop can be pivoted out of the way for making bevels of less than 45 degrees. The fence tilt mechanism is well-built with heavy cast-iron and sheet steel parts. All knobs and levers are heavy-duty and provide plenty of leverage for snug lock-downs.

Dust collection has been very effective. I discarded the 4" plastic dust port that came with the unit and installed a shop-made 6" port over the 6"x6" dust chute. Now chips never accumulate in the stand or on the tables and dust is virtually eliminated as well.

I've had the knives sharpened three times now. The jackscrew blade adjusters are great--easy to get a fine tolerance. Removing and replacing the knives is a no-brainer.

In five years of moderate use, I've not had to do any tuning other then adjusting blade height to compensate for sharpening. This is a very well-made and well-finished tool, and I recommend it wholeheartedly.

I have owned this machine for about 2 years now and it works as well today as it did when I first purchased it. I did spend a great deal of time checking out other brands but kept comming back to the Jet. Finially I went home with one and have been very pleased ever since. While some review complain about snipe this is easily controlled by properly adjusting the height of the out feed table which is covered well in the manual if you take the time to read it. Both infeed and out feed tables are controlled by large hand wheels and are easy to make even fine adjustments. The levers on other models made it difficult to make small adjustments. In use the machine is quiet and steady. It has plenty of power and it really can produce large amounts of saw dust! An dust collector is almost manditory with this machine. With the large 4" dust collector you can be sure that all of the saw dust ends up in the DC rather then on the floor. Fit and finish is perfect. The standard fence is top quality and easily adjusted for perfect 90 and 45 degree settings. The only better 6" machine may be the Powermatic 54A with a 20" longer table but it will cost you 35% more then the Jet. You really do not need the longer table as you can quickly make any 8' board straight as an arrow with the Jet. Just take the time to set it up properly once and whenever you change the blades.
