Product Description

Amazon.com Product 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 Box
The 40-031 router table extension comes with a full-feature fence, pre-drilled insert plate, and all necessary mounting hardware.

5.0 out of 5 stars A great idea that is well executed., October 8, 2004

I ordered this router table extension wing to mount on my DeWalt DW746 tablesaw (on the left side). Although the Amazon site indicated shipment in 1-2 weeks, I waited nearly two months for mine to arrive. When it did arrive, everything was in perfect condition and all of the parts that were supposed to be there were included.

As I unpacked this router table wing, I was very impressed with the quality of the casting. I wish every piece of cast iron equipment I own was finished so well! The assembly/instruction manual was ok (I have had better and worse). Mounting this wing to my saw (by myself) was not a problem. Although it is HEAVY, I followed the advice of another reviewer and mounted the center bolt first and then followed with the other two. Even without shimming it, I would say that I was able to get this wing 99% even and flat to my saw table. Once the table was flat, installing the miter track and assembling the fence were a snap. All together it probably took me 1 1/2 hours to unpack and assemble (I was being very methodical).

I am very pleased with all aspects of this unit. The only manufacturing problem I found was that one of the t-knobs used to tighten the fence down to the table was a bit cross-threaded. One quick call to Bench Dog solved that - a new one was shipped to me immediately.

I have to say that I am thrilled with this purchase, both for the great design and for the excellent quality of the workmanship put into it. I will not hesitate to buy from Bench Dog in the future.

5.0 out of 5 stars The Fit, the Finish, the "Adjustability" Makes it 5 Stars, December 26, 2001

This review is from: Bench Dog 40-031 ProMax Cast Iron Router Table Extension for a Table Saw Includes Fence and Insert Plate (Tools & Home Improvement)

I received the RT-250 about a week ago...This is EXACTLY 27" deep, front to back. The big advantage for me is that I did not have an extension out the side of the saw. Now I do, and it doubles as a router table. A very precise one at that... I had to use the installation kit, which is $15. ...The great thing is that I went from being able to cut only a 9" wide board on my table saw, and still use the fence, to being able to cut an 18" board, using the fence that came with the router table.
I am able to use the crosscut fence, that came with the saw, on the face of the router table also , because the slot in the router table is exactly 3/4", the same size as the one that came with the table saw.
The router table, comes with adjustable screws all along the 3/4" fence track, and they are about every 2 inches apart. You are able to adjust the play in the track, so your fence rides PRECISELY along it...The ultimate router combination with this table is the new Bosch 1617EVSPK, which is a combo pack, with a plunge base, and a fixed base, and the motor, very easily, slides out of one and into the other. Why is this so compatible? Because the plate that comes with the the RT-250 is made out of thick plexiglas. (Unless you buy the optional heavy metal one for $90) The manufacturer advises you to not leave a heavy router of more than 2 HP, installed in the plexy plate for long periods of time. If you are not using it for awhile then remove it. No problem the plexy mounting plate is held into the table with only 2 heavy screws, so for long term, you simply remove the plate. That of course leaves a big hole in the table. Something you can fall in when making table saw cuts. The solution, save the money from buying the optional metal mounting plate, and buy the Bosch 1617EVSPK. The motor is easily removable from the super light fixed aluminum base that you leave mounted. Then you have the option popping the motor into the separate and included plunge base, thereby giving you another handheld router to use. Then the hole it leaves is a little two inch one. (Approxiamately)
If you want to not change your settings, and keep the motor in the table for a long period of time, that is not a problem. Yu can remove the motor, with just the two screws holding the plexy plate into the table, and later on reinsert it, while still maintaining perfect settings. The router mounting plate is just that precise.
As a matter of fact,in keeping with Bench Dog super critical tolerances, they give you 12 under that table mounting lugs that are fully adjustable, which press against the underside of the router mounting plate, just to make sure you can adjust the plate PRECISELY FLUSH to meet with the router top face. Phew, you have to respect that kind of precision. Something hard to find in the world of tool making. I guess that is why Fine Woodworking rated them number one... It went from the worst condition tool in my shop, to the nicest showpiece...There are not linear measurements with the RT-250. At first I was disappointed. How am I going to get the Bench Dog fence parallel to the edge of the table. Then I read the directions, and I have to agree. It doesn't make any difference. The fence has to be true to the bit, not to the edge of the table. You can even loosen just one screw on the fence , and make fine adjustments with it.
(You can use a T square to make it perfectly parallel to the edge of the table. That is only neccessary if you are ignoring the router fence, and using the crosscut-t-square fence that comes with your table saw to move your work past the router bit, in the 3/4" groove/track in the router table.)
I love the included plexy mounting plate. With the Bosch fixed base which will stay permenantly mounted to it, the two large maple handles that come with the Bosch 1617, show right through the glass... What is important? The fact that you can get this table to mount precisely to the your saw. Perfectly flat, perfectly level, and smooth with the top.
Even the mounting nuts and bolts that hold it from underneath to the edge, of your saws table, are adjustable due to the adapter plate that comes with it.
The optional attachments make this even a more valuable addition to your shop. The Bench Dog feather lock, and
panel lock options, give you work tie down, and feathering capabilities you would have a hard time replicating on your own. I know featherboards are makable, but the combo, with precise fitting flanges mounting into your router table, with a simple twist of the knobs, and standard table saw grooves, make these something you will want to get for your other equipment as well. No super reaching clamps to have to contend with... Last note, the fence is easily removable, and stores quickly using the two hooks which are provided for that purpose. So if you are using it for routing, or turning it around to use it as a long distance fence from your saw blade, it is quickly and easily removed/replaced with just a twist of the two large wing nut locking knobs located on the top/sides of the fence.
If you're short on floor space, need a precise router table, and need an extension for your existing table saw, or are willing to replace the extension you have, then this is the one for you.
Have you ever experienced the frustration of spending a lot of time getting a perfect setting, then quickly cutting your piece, only to have to spend a lot more time getting your next setting, then making a mistake, and needing the first setting all over again? The solution, get multiple tables.
Set em, then set em aside. Go on to the next table. You won't lose any settings. Makes short of a lot of work. The RT 250 makes for a nice addition for that.
That is what the RT-250 is, my third table. Professional router instruction books tell you that three tables are recommended just for that reason. Yes, that and a separate handheld. That is what I now have.. precise, fine fit, and finish, make this a welcome addition to your shop. I am sure it will last for a long long time. Happy woodworking! I hope this was helpful.

5.0 out of 5 stars great fit for my unisaw!, April 21, 2005

This review is from: Bench Dog 40-031 ProMax Cast Iron Router Table Extension for a Table Saw Includes Fence and Insert Plate (Tools & Home Improvement)

like most of the reviewers I have a very small shop which was one of the main attractions of this piece but after using it I wouldn't use anything else even if I had the space. Another reason was, it is probably the easiest way to install a prolift onto a unisaw, originally I was going to install it in the right extention table. first the casting is very nice, thick, heavy, and all edges are crisp but not sharp, the overall finish is impressive. the fence is also a surprise, the extrusion is thick(3/16ths) and solid, the harware is nice and it is a joy to use. The dust port works well and with the accessory slots the fence is very versitile. I can't comment about the router plate because I used the prolift. the installation was a breeze, the table was exactly the same depth as my unisaw top and fit snugly between the rails of the biesemeyer, I didn't even have to remove them. the instructions were clear and more than enough and the the installation was quick, about an hour(if you don't consider this quick you have issues), it didn't even need shiming, please look at the pictures I posted of it installed on my 1954 rockwell unisaw. Now the performance, man is this thing solid, the table weighs 55lbs the prolift with Porter-Cable 7518 router weights 34lbs together thats 89lbs, now attach that to an already 400lb unisaw and that puppy isn't going any where. vibration is like nill and it really translates into a super smooth cut and the prolift gives you so much control. The flatness of the table when used with the prolift make the cut super consistent. You can also bring the biesemeyer over and use it as a guild or a stop, its great. only two minor gripes, one the hard anodised aluminum miter slot works fine but I wish it were just a slot in the cast iron and two when used with the prolift the clearence for the blade angle wheel is a little tight on the unisaw (see my pictures). Overall I say BUY IT and a prolift it is well worth the money and the wait. Again even if you have the space for a dedicated table I still think this works better, besides that is space that could be filled by another machine I mean really! also made in USA big plus.
