Default Large Dado Cuts

Hi. I am beginning a project to build a rolling kitchen island. Before I bought the materials I hadn't noticed the required 3 1/2" dado cuts required. I don't have a workshop, I live in a condo and have use of the basement. I have a Skil router that I have never used and have been reading about ways of doing these cuts for two days now. If this was an inch cut I could totally visualize accomplishing the four of them, but it's not, it's three and a half inches wide, 1 1/2" deep in a 4x4 post. I'm just not sure if there is a particular method and/or bit. Suggestions for methods, guides, videos or books; anything to help accomplish a task that I have never witnessed. I do not have a table saw that is equal to this task, and for all I know, perhaps I don't have a router that is equal to it either.
Thanks.

Do you have a hand saw, a sharp chisel and a hammer?

I’d just saw almost to the 1 1/2 inch mark, hit the chuck of wood in between the cuts with the hammer knocking it out, and use the chisel to pare the rest of the wood out, test fitting the joining piece as you go to get a perfect fit.


In woodworking there is always more then one way to accomplish something.

Hi Buddy and welcome. I've done it the way Terry described many times. Usually making the many kerfs with a circular saw. You can use a router to finish the notch to a perfect depth and smooth bottom but I would only notch the center 1 1/2" first and then move outward from there or you won't have enough surface area to rest the router on.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Chuck, if I determine that I can adjust the depth of my very old circular saw, that is what I will do.

Welcome Buddy,

As you can see help is here and always willingly shared. You've connected with some very skilled craftsman and the advice is always helpful and from experience. Looks like it's time to go through the material Stick referenced and see what that router can/will do. Of course always practice on some scrap first but you'll find the router to be a very accomodating tool when used properly. Just make sure you read all the safety and proper use material carefully as it can be a problem when used improperly and be downright dangerous. Proper cutting direction and depth of cut on a single pass is key to safety. When removing a large amount of wood is necessary always make multiple passes, each cut going deeper or further into the cut than the last pass. Trying to take a lot in a single pass is dangerous and not nearly as clean as multiple passes. Again, read Stick's attachments and save yourself some grief. Having maybe caused some fear/concern, and that's a good thing, you'll find when used properly that the router is truly a wonderful and versatile tool capable of many uses.

Enjoy the project, keep safety first, and learn in baby steps.

You can pick up a small table top bench saw off craigslist and store it under your bed for future projects. I was able to find one for $25 dollars and a miter saw for $15 dollars. I needed them for one time job I was doing at the condo and didn't have access to my workshop at home.

Unless I'm reading your original post wrong, you're trying to make a 3.5 inch wide dado or grove the length of the 4x4. A 4x4 is only slightly thicker than 3.5 inches. So I think you might mean you are cutting a 1.5 inch wide groove across the 4x4. Is that correct? If it goes the full width of the 4x4, then I'd buy a hand saw, and probably a Japanese pull saw, mark the depth of 1.5 inches on both sides of the 4x4, and cut the outside edges of the dado first (just shy of the mark), then make many cuts with an ordinary saw, or even a circular saw, and then chipping out the remaining pieces with a very chisel. Then use a chisel to pare the bottom flat all the way across. Don't use a mallet for the final flattening. Wiggle the chisel back and forth and take very light bites. Use a straight edge or ruler to check for flat, and for the exact depth of cut.

This might be the time to add a couple of tools, such as a combination square and GOOD chisel set. These will last your lifetime, travel easily and you'll find many uses for them. A speed square is cheap and can guide a hand or circular saw to make square cuts. You can get a lot of projects done with a decent circular saw and a straight edge. Mine is a Makita, but there are many other brands, including AC or battery powered ($$$$$).

The more I do, the less I accomplish.
