Topic tags/keywords: question tablesaw dado freud

After searching out several old threads on dado sets, I picked the Freud SD208, $84 on Amazon

I want to set up for a 3/4” dado, but I am not 100% sure how to place the chippers, and frankly, I have a healthy respect for that much spinning metal and I have no desire to screw it up.

I know that you need to offset each piece in the stack so that you don’t have any carbide on carbide contact. I can do this two different ways for the chippers right next to the outer blades:

Between the teeth:

Or straddling the teeth:

Is one of the ways correct? The instructions say to “align the chipper with the two open spaces on the outside blade,” but as far as I can tell the teeth on the outer blades are all spaced equally – there’s no “open spaces.”

Once know how to start, I’m pretty sure that I can get the rest of the stack from there.

On an educational note, what is the purpose of the protrusion in front of the chipper tooth with no carbide on it? Is it just balancing the weight?

I align them as you have in the first photo. I’ve never had a problem.

The protrusion in front of the carbide in the chipper, as I was taught, is a limiter to reduce the amount of wood that can enter the carbide area. It’s the same concept with the large hunks of steel behind the carbide on router bits.

I’m no expert but I do it as shown in the second picture. Also haven’t had problems. Side note on the instructions – on mine the summary they give of what combinations of blades, chippers and spacers to use for various widths of cut is wrong (in some cases by 1/8 inch!). I check by hand so don’t really care.

Run test pieces as 3/4 ply is not 3/4 thick. YMMV.

As long as the chipper teeth do not touch the other teeth you are good. If the teeth from one blade touch another you will see a gap between the plate part of the blades and this will cause problems when you try and tighten the stack up. You will bend the blade as you try and get the gap out.

1+ Chris’ comments. I stagger the chippers to keep the set balanced.
I usually us a 3/4” dado setup (2 outer blades and 4 chippers). Always use both outer blades, never just one.
Notice how the teeth are set on the outer blades—- one is the inner blade, and one is the outer blade.
You can tell by looking at the angles of the teeth. Place the blades so the angles face inward toward the chippers. This helps to score the wood for clean cross-grain cuts like tenons.

You will get a lot of use from that set. I use mine on every project.
