Best way to cut dados, tablesaw or router?

[Dino Makropoulos]

John, with Jim, I'm pretty excited to use the FESTOOL MFT to cut dados. For simple operations, I'll stick with the table saw, but for sliding dovetails and matched dados for carcase sides, the MFT is the way to go.

Jason.
There is not "simple operations" using your table saw.
90% of woodworking mishaps are from "simple and fast cuts" or dados.
Just find ways to make your dados simple on your MTF and router.

The main reason I hang on to my big old (1963) 12" Craftsman RAS is cutting multiple repetitive dadoes in panels as wide as 20". Otherwise the TS, routers, CS and 12" sliding miter saw do it all.

Used both methods and prefer TS. You do need a high quality dado blade for good results, but a good dado blade can easily cost more then a good router.

John,

IIRC, you already use a Festool CS and guiderail, maybe the MFT as well. If so, you are a router away from a nice dado set-up that works expecially well for mirrored dadoes. I find the ability to have repeatable set ups is very useful. Many times, you can dry fit the joint to your satisfaction without even moving the cut-piece, or, even if you do, it can be repositioned with perfect repeatability. On big work, there is less chance of unwanted movement that could spoil the work, or worse, hurt the operator.

The upside to the TS is speed when you have a higher volume need, but, if the work is big, you need a big square footage to be safe.

I've done both (all three, actually- TS, Router with guide or jig, & Router Table). Never did it on the RAS I no longer have. I prefer the router table (i've got 18" between the fence and the bit to use), mainly because it saves me the setup time involved with removing blades and installing stacks. I just pop the appropriate bit in set the fence and rock on. Anything specialized I'll use jig and guide and a plunger. If it is a tall bookcase or Ent Cent, then having a sliding table saw with supports and presests comes in real handy with a dado stack. I get great results with all of them, and like many have said, quality cutters yield good results, no matter your preferred style of plowing.

I used to do dado's on the TS but have gone exclusively to the router. Infinitely faster to set up and much more accurate when done with a router and jig.

Like Ray, I have switched from the table saw to the router. Although I have probably cut a couple of hundred dados on various table saws, I was never really comfortable doing so. So I agree with Ray that the router is "Infinitely faster to set up and much more accurate when done with a router and jig.". To that I would add that a guided router is much safer.

actually it depends on the task at hand. this leaving yours and rays coment at 50/50. different tasks require different procedures. with this one could do it either way but would or may not be the best way.....jack

Have used the TS, Router,and RAS. Find the RAS quickest while not the safest, the cut I get out of it is the poorest (one of those craftsman wobble jobs). My router cuts the cleanest but is the slowest to setup (don't have one of the guides everyone seems to argue about, they may be quicker to setup then my jig). The TS is what I go to for non-stopped, I like the cut and control I have, the TS being what I grew up using I may be a bit biased. Of course if there were a router guide manufacturer out there somewhere looking to donate a guide to the Bob fund I might change my mind.

I have used both the TS and guided router to cut dados. Until recently I used the TS most of the time. A couple of months ago I tried the Festool guide rail on a MFT and the OF1400 router. I got dados that are every bit as accurate as those on a TS, and I felt the setup time was shorter using the router setup. There is less chance of messing up a cut using the guided router, IMHO. I think there are occasions where one method might be better than the other, so having both available is a plus. When dealing with large panels, it seems easier to me to move the router over the material as compared to muscling the panel through a TS. I think in the future I would use the Festool guided router setup as my first choice.

Probably fodder for another thread--I have found a small--I think--6+ inch---"wobble blade"--perfect for my frequent need to cut 1/4" grooves for drawer bottoms.

Works well on mostly on TS, seldom on RAS or occasionally, the need to use a guided CS. Quick set-up. Always test!

I use both...for long dados (think vertical plywood carcase walls) I use the TS....for crosscuts, I use the router and a guide.
