The DadoMax makes easy, accurate router dados. Setup is easy and it makes tight-fitting dados regardless of material thickness. The DadoMax is constructed of high-quality materials, and has a large enough surface that there is no worry of the router tipping. It comes in a metal case and includes replacements parts for items that might be easily lost. The DadoMax adjusts to a variety of straightedges, and you can buy the DadoMax without a straightedge if you already have one.

I only gave four stars because:
  • The DadoMax slid easily on some parts of the straightedge and tended to jam on other parts – probably a slight variation in the width of the straightedge. A little wax might take care of the problem.
  • The DadoMax didn’t come with any instructions. While not too difficult to figure out, an explination of setup and adjustment should be included.
  • You can get the same function with comparable accuracy with a simple shop-made jig. $139 seems like an expensive replacement for the shop jig.

————————————————————————————————————————————————
I was very surprised to find that there were no instructions for setup or use. I know a lot of guys don’t like to read instructions, but it seems like anything that needs setup or adjustment should come with instructions. Here’s a quick run-down for setting up and using the DadoMax:

First, adjust the DadoMax to the width of your straightedge. It should be tight enough that there is no “slop” but loose enough to slide easily. The two knobs on the left allow you to adjust the guide.

Next, adjust the spacer throat to match your router bit. Loosen the screw with the hex key that is provided, and make sure the throat is exactly the size of the diameter of your router bit when the DadoMax unit is fully closed.

Install the provided router bushing and make sure your baseplate is centered on your router.

Set the DadoMax to the thickness of the material using an actual piece of the material that will fit in the dado. The spacer throat is stepped so router bits of various sizes can be used. When using a ½” bit, the stock fits on the outer step as shown. For a 3/8” bit fit the stock on the middle step, and with a ¼” bit use the inner step. Set the DadoMax fairly tight using the adjustment screw, and lock it in place using the jam nut.

Mark the location of the dado on the workpiece. Place the DadoMax on the straightedge and align with the location marks. The DadoMax has three alignment marks, again depending on which router bit you are using. I’m using the longest alignment mark with the ½” bit.

Set the router on the DadoMax, and slide the router along the straightedge and back. The DadoMax will allow the router move slightly toward and away from the straightedge. On one pass press toward the straightedge and pull away from the straightedge on the return pass. The resulting dado will be a tight fit for your your material.

I didn’t have my straightedge clamped tight enough on my first dado, and it moved. The second attempt resulted in a tight dado. Be sure your clamp is tight so you don’t ruin actual parts!

Excellent review. I’m surprised that there wasn’t a War and Peace size novel inside full of warnings, cautions and general covering of the @#$. Usefully the lawyers attempt to alleviate all liability to protect the company.

Interesting I guess I’m missing exactly how it works.

Jim, the router bushing sits in the “throat” in the middle of the tool. When you set the tool to the thickness of the material, it opens the throat so that the bushing can move a little bit towards and away from the straightedge. You make a pass with the bushing close to the straightedge and a return pass with the bushing away from the straightedge, so you are cutting one side of the dado with each pass … so, for instance, you can make a tight 45/64” dado with a ½” router bit.

Thanks Peter
I didn’t get that before but you explanation made it perfectly clear. There are a number of shop made jigs that work the same way, I just hadn’t seen a factory made one that works that way. Thanks.

Jim, I’m with you – this works fine, but I’m not sure it’s $140 better than my shop jig.

Router, the video does a good job of explaining. Still, it seems like some kind of instruction should be included – not everyone with a router is a YouTube user!

I have one of those but they called mine Dadowiz??
Wonder if it changed hands or the patent is gone?
It seems to be selling for $86.00

I with you Peter – there should be instructions included with product, regardless of how simple it is to use. Very nice reveiw. could this also be used for making mortises (short, deep stopped dado!)- I guess without the instuctions they do not tell you the limitations.

http://www.woodline.com/instructions/Dadomaxmanual.pdf this is the link to the instructions for the dado max

I just noticed this thread while nursing my “Dadowiz” back to health.

It’s really and ovepriced gadget. I’m glad I have it but what was I thinking?

For what it’s worth, there is no reference mark to adapt this thing for stopped dados which I am rather fond of.
The clamp that comes with it has slot for Tee screws but they seem too small for standard T slot screws?
the manual or the websites offer no explanation of what the slots are for.

I just received my Dadomax and am kind of disappointed. Instead of the two knobs allowing adjustment to fit a straight edge, my version has just a single hex nut that secures the sliding bar to the edge of the Dadomax. Full disclosure; I haven’t tried it out yet, but it looks a little flimsy conpared to the ones in the video and the instruction sheets.

Looks like the Dadomax may be a thing of the past, but the Dadowiz is very similar and is availalbe here.
