Editorial Product Review:Amazon.com Item Description:Thanks to the clever folks at Bench Dog Tools, woodworkers everywhere can now enjoy the speed and precision of stationary routing without having to buy or build a router table. The 40-031 ProMax Router Table Extension bolts directly to the edge of most 10-inch table saws, thus providing a flat, rock-solid platform for mounting a router.
The roomy cast-iron extension measures 16 inches wide by 27 inches long, and comes with a durable phenolic insert plate for mounting the router, and a smooth-sliding fence. The table has an adjustable miter gauge T-slot and an accessory slot that accepts featherboards and other accessories. The fence has adjustable sub-fences, a dust-collection port for attaching a vacuum hose, and two integral jointer settings (1/32 inch and 1/16 inch) for jointing board edges perfectly straight. When not in use, the fence can be removed and hung on two hooks beneath the extension table, or left in place and used when cutting on the table saw. --
Joseph Truini What's in the BoxThe 40-031 router table extension comes with a full-feature fence, pre-drilled insert plate, and all necessary mounting hardware.

Wonderful Space Saver
I bought this when I replaced my 35 year old table saw with a Jet JPS10 Hybrid (both from Amazon). The installation was very easy, 3 bolts on the side of the table. I called ProMax to check if any other support was required. They assured me that the 3 bolt installation was all that was required.
I've been using it for about 6 months. One of the best tools I own.
1. It saves the space required for a separate router table.
2. It's incredibly handy, right next to the table saw. I now use the router table twice as much as before.
3. It's built like a brick outhouse. The aluminum fence is very easy to use and accurate.
I highly recommend it for any serious woodworker with a small shop.

Compatibility
This is obviously not a review, rather a question. Does anyone know if this compatible with a left tilt saw? I have emailed Bench Dog for the last 6 months but no response.

Well made kit
Exceptionally well made, clear instructions as to how to install. Configured for most table saws with a 4 or 3 hole install on a 27" table edge.
I can't imagine putting this on a contractor or lightweight hobbyist saw without extension legs to support the heavy cast iron base - to be fair the instructions recommend support legs in that situation.
Mine fitted my Grizzly Hybrid G4078 just fine and the very flat table supported by the mass of the saw gives an excelent router table in my limited space garage shop.
The insert plate comes with most "standard" router holes pre-drilled - an excellent full scale template gives drilling centers for most other routers on the market if you have one not covered by the supplied plate. The fence is solid for it's dimension. Includes fence inserts to allow use as a small scale joiner for preparing boards for edge glueing. Dust port works amazingly well for its simplicity.
Highly recommended.

'nother five - results for Delta LT 10" contractor
I agonized for months over the price, and finally did it. All the way.
I've added mine to a Delta Left-Tilt 10" contractor 36-982. There were a few minor problems on the install (nice tip on the extension roller). I pulled the left extension plate from my saw, replaced it with the Benchdog plate, and was then able to bolt the spare Delta left plate directly to the right side of the existing right extension plate. All of this takes up no additional space in my very small shop. That all took about a hour, fiddling with the roller, moving the saw, working the bolts, leveling, etc., mostly due to the weight, plus a small fudge factor for operator ineptitude.
Next I started to assemble the other parts including the miter gauge guide track. In screwing the track to the plate, I found that either the counter-sink holes for the screw heads had not been drilled deep enough, or they shipped screws with heads too high. In any case about 1/16 - 1/8 of an inch extended up into the track making it impossible to move the miter gauge bar in the track. I called BD and they attempted to talk me into drilling the countersinks deeper, but for $329, I expect them to ship properly machined components. I'll report back on how long it takes them to ship the replacement, and if it's any good. Worst case, I have a drill press and the correct sized drill so I can fix it if necessary, but if I have to jury-rig an expensive tool to make it work properly I won't be happy.
6/11 report back - BD shipped a properly machined replacement track (counter-sinks on original were not deep enough) immediately, and I had it in-hand inside a week. It now all works just peachy. I'm using my Biesemeyer rip fence, and my Delta and Kreg miter gauges. Nice. I came away with the impression that BD maybe has five employees; but they seem to know machine tool work when they set their minds to it. The customer service call went through Rockler, by the way. They took the call at the 800 number and sent an email to BD about the problem. The email was the only description that came with the new part.
The additional plate on the right causes no instability, so I haven't added the support legs. I had not installed the Delta right side wooden extension table, so now I have spare parts. With the saw now weighing in at over 300 pounds I don't see much vibration. The length of my table is now nearly 60 inches, and all of this took up not one inch more space in my shop.
A truing block I use to check my saw table can identify no problems with the Benchdog table anywhere, and it looks like they may have read some of the posts here because the sharp edges on my table were already rounded.
The phenolic plate is solid but not exceptional. Okay for something like a PC 690 router, but not something heavier.
I followed this purchase up with the Pro-Lift/PC 7518 router combo. It's evident that somebody talked to somebody, because the only evidence I see that the saw, the table, the lift and the router weren't all intended to always be assembled together is the BD table is a different shade of grey, and even that's changing as it gets waxed, etc. Seriously, the left-side Delta extension moves to the far right side with no modification; Delta even left pre-drilled and threaded holes to accommodate that change. I had to add some new lock washers, but that was it. The weight of the router and lift on the left just about perfectly balances the extra plate on the right. Vibration is trivial for either the saw or the router.
The fully depressed router doesn't even come close to interfering with the angle adjustment wheel for the saw blade. The router fence barely comes close to touching the router when hanging under the table. When extended the router collet extends well above the top of the table for changing bits. The only inconvenience is having to reach under the table and around the router to change the speed.
I have to use space as efficiently as I can, and I can't imagine a more effective way to add a router table.
