Topic tags/keywords: blade tablesaw

Just started building cabinets. Right about now I’d give my left…. uh…. very important body part for a dado cutter. :)

Making multiple passes for each piece on the router table to cut a rabbet or dado gets old REALLY fast. I’ve never owned a good table saw before so I’ve never owned a dado cutter. I used a stack dado at a friend’s house a few years ago. Was a little fiddly to set up, but not terrible. I’m not sure I’ve ever even seen a wobble cutter.

This is for a Steel City 35990. (in case that matters). I have some blank ZCI standing by and I know I’ll want to cut a ZCI for dadoes.

What should I be looking for? I’m not going into cabinet making, but I have about 18 more cabinets to build after these 2 ….. then I figure the dado cutter would be a good thing to have and I’ll use it more once I get rolling into retirement at a better pace. :)

thanks for any input.

I have been happy with the onsrud dado set I got off of ebay.
It looks like there are none available right now but he usually has them.
I paid around $30 for the set I have.
I would compare it to some sets that cost over $100.
Here is the link to his store.
I have bought several other blades from him too and been happy with all of them.

Skip the wobblers…not flat cuts, very few high quality examples available. You’ll be far better off with a good dado stack. The Onsruds were a great deal while available at clearance, but I think they’re gone. The current best bang for the buck is the Delta 35-7670 set, that happens to be on sale from Cripe for $74 plus s/h.

The $100 dewalt/delta dado set got a good review from Scott. He’s the man to trust with blade advice.

I messaged onsrud on EBay and the dado sets are sold out and probably not returning. The Delta set looks good. I’m guessing that more teeth means smoother cuts. When looking at stacked dado sets I see mostly 12 and 24 tooth sets so I’m leaning towards 24 tooth. Looking around while typing this and it looks like I’ll get the Delta set, so now I have a question on how to USE the dado set…

Making rabbets, approximatly 1/2” by 1/2”. Using 3/4” birch plywood. I would assume this is a single pass operation on the table saw. Correct?

I like my Frued 8” Diablo set but, replaced the shim set with a set of magnetic shims I found at Woodcraft.

Good luck!

I agree with knotscott, avoid wobble dado blade. Look for a stacked dado with more teeth (finer cut gives less chipout) Try to do dado with one pass, any extra passes will create more chipout as well. When I work with Melamine (which is rare) I use table saw with one fine blade, makes two passes creating the width of dado I need, then clean it out center with router and smaller bit, or sometimes just a stanley hand router. (If you have a LOT of dado’s the cleanout method is more time consuming) I have found lately with this METRIC crap we have the thickness of plywood material varies. MY old 3/4” dado cutters are to large or too small for thickness of what and where I buy plywood. You sometimes haves to make test cuts.

When you do get that dado set ive found that a great way to have your set up correct everytime is to run what i would call a sample board. Make every possible dado with all the chipeprs on a single board. I labeled every chipper with a number. for example both blades on i took #1,2,3, 5 and made a cut, labeled it on the board, i took #2,4 made a cut and labeled it. This way you can take your stock that needs to sit in the dado and perfectly match it up with the widths on your sample board. In the long run its one heck of a time saver.

Thanks for the advice and tips, guys. I bought the Delta set from Cripe.
I like the idea of making the test board. This is going to arrive after I’ve left for Florida, but it will be here when I get back and that’s when I planned to go ahead on the bulk of the cabinets. This ought to make the process, faster, safer, and easier.

Appreciate the help.

Another option is to make yourself a jig and use your hand router with a downcut spiral bit. The jig will line up perfectly with your dado layout. One side of the jig would be set up to handle use 1/2” bit for narrower dado’s and the other side setup to work with a 3/8” bit. You can make a couple of these jigs to handle whatever dado sizes you need. The beaty is, the edge of the jig that the router plate rides on lines directly with one side of you dado. Then you flip the jig around, line up the edge with the dado line, and finish the dado.

I used this method for many years before I bought my CNC. I tried the table saw with a dial micro adjuster and it just took way to long and used a lot of plywood to get things aligned just right.

Although conventional wisdom says that wobble cutters aren’t as good as stacked cutters, I’m getting excellent dados with this Craftsman wobble cutter that a neighbor gave me 10-15 years ago. It has more teeth than any other wobblers I’ve seen and I think that’s why it works so well. I prefer it over my stacked cutter because it’s much quicker to set up and tweaking the cut width is much simpler.

Here is a sample I did this morning while setting up to run some drawer boxes.

I have to agree with Sawkerf, I have been using a wobble dado by craftsman for years, with no complaints. Funny thing though, my buddy has a wobble dado as well and looks very similar to Sawkerfs, mine does not have as many teeth and is shaped more like a traditional blade just thicker and of course smaller diameter. Funny I have not been able to find that one in sears ever since I got mine.

the fifty dollar mibro set from Lowes works very well…. I have used the same set oh 5-6 times a week for about two years or so, may need cleaning from time to time but sufficient for a pro, so probably for you to.

the problem with a wobble cutter, which I used once and never will again, is that the blade doesn’t move in a straight path, therefore it leaves an angled cut, and while you can work around it, it can be a pain if you’re trying to get a really precise fit.

Whichever you use though make sure you have enough room for the blade stabilizer as well as the nut.

I have found this to be extremely useful in making dados with a router.
I will actually reach for this jig before setting up the blades in the table saw getting the fence in just the right position, which is actually nice because you can just leave the saw set up to cut your parts.
