I got this old Craftsmen Dado blade set from my father and I don’t believe it’s to blame as I’ve seen it work first hand and know people who use Harbor freight ones with success too!

My pattern seems to be to try a practice piece of wood with success and than when I need it to work get what you see in the picture. Total blow out of the plywood!! Does anyone have any suggestions on what’s causing this? I try to spread out the chippers as well as offset the teeth, so the identical ones aren’t side by side!

Thanks!!

If you use a utility knife and mark the cuts going all the way down past first veneer, it should give you a better result. Suffice to say sharp blades are essential. It doesn’t look like it is caused by wobbly dado.

Have you installed a zero clearance insert plate on your table saw just for the dado blades? That should help. But in my opinion; the Craftsman dado blade is junk compared to others. I purchased a dado set at Rockler with their 20% coupon a few years ago (under $100) and it made a huge difference. Don’t remember the brand. You get what you pay for.

+1 for Julian. The better the dado set, the better cuts they make. I have tried using cheap sets and got really poor results.

I don’t have a zero clearance for it, just the stock rigid one. Wouldn’t I need a zero for each width? It good just be cheap and dull like suggested. Just weird that it’s not consistent.

Sharp blades are key, especially for the side cutters, one of which looked like it got a little hot!

Sharpness/quality like others said. I got an ‘ole craftsman wobble dado that cuts cleaner.

I can certainly understand the sentimental value of that set, but the proof is in the pudding….that ply can be tough to tame, but that’s a horrible cut. At the very least clean it up, and see if you can good techniques for sharpening a steel saw blade with a file. Add a higher quality dado set to your wish list….

Been using THAT set for a few DECADES, no problems like that. Might just need a sharpening??

Zero clearence inserts do help, though.

Been setting mine uo on the arbor, so that the teeth on the outside cutters match the wat the face out. Won’t worl too well in the both lean out to the sides at the same time. Might also take just a bit of the set off the teeth…

Same set that Vermont American put out, just VA had more cutters.
