I need a new dado set and have been looking at various blades. Which one would you recommend? Standard stacked set or a wobble blade and why?

Thanks,

Ray

Stack gives the flatest bottom.

The day I got rid of my wobble was a great day...

Flatest bottom - would be a finger joint/box joint set. I have a two-piece set made by Forrest for making box joints on the table saw (drawers, etc)

What do you plan on doing? Wobble are going to be easier to adjust. As long as you get the shoulders cut where you want them you can always go back with a router and clean up the bottoms. A router bit like this works great

That being said, I don't remember the last time I used a wobble. My Freud 8" set has served me well (2 blades 6 chippers)

When I got my stacked, I tossed the wobble. I addition to the roundish bottom with the wobble, I found it was harder to accurately set.

Go stacked, not wobble. Wobble makes an inferior cut that usually needs touching up. Probably ok if you are doing rough lumber projects but for furniture or well made projects, stacked is the way to go.

Got it. I'll pick up a new stacked set. The one I have is circa 1960 or so and chipped a bit.

Thanks to all

High quality cuts? Freud stack. Have to fuss a little with added or removing the chipper blade and the shims to get an 'exact' cut width. But you can get an exact width, especially important if fitting plywood (that is NEVER to its nominal size) into the dado/groove.

Quick but not as clean cuts on the shoulder(s) and not necessarily a truly flat bottom would be a wobble blade. Some cut 'better' than others, but most (all?) do not do as clean of a cut as a 'good' stack dado blade.

If it matters to you or the cuts, double check even on a stack dado blade as some sets have the 'outside' cutters with rather aggressive 'scoring' teeth that WILL leave noticeable score/groove marks on the bottom of the cut.

For the best flat bottom dados/grooves without scoring marks, check for a 'box joint' blade set.

Forrest blades are usually good to very-good, but usually seem to bit more expensive than even ' very good' Freud blades.
