Topic tags/keywords: stack dado shim table saw question dado groove

I have a Grizzly H7777 8” stacked dado set. The blades are not accurate in thickness as marked and I need to use the shims to get to the desired dado width. I have a lot of trouble installing the shims. They are thinner than the spiral groove in the arbor and usually fall into the groove instead of aligning flat to the chipper or end blade. Are there some techniques that I am missing? I would think any shim thinner than the arbor groove would have this problem. When I tighten the blades and shims the shim is usually deformed and takes up more space than it should.

Just use one between two adjacent blades, and you should be fine. You have to work them into position by hand. That said, it would be annoying to have to shim every cut. I only use them for oddball plywood dados.

I’ve run into this problem too, it’s a PITA, practice makes perfect.

I’ve had the same problem in the past. I’d suggest putting a very small dab of axel grease to ‘stick’ it to one of the blades. Install the blade/shim combo… Make your cut. Then simply wipe any remaining grease off before storing back in the box.

Hadn’t thought of the grease idea, but that would help ease my headaches sometimes, I would run the saw for a minute or so, then shut down and make sure no grease had been flung to where it would get on my work piece.

Has anyone tried magnetic dado shims like the ones eagle America sells. Eagle says they will never
slip into the arbor threads.

Collect magnetic business cards. Cut a hole in the middle, and “Bob’s yer uncle”.

i’ve found this method by the woodwhisperer to be quite useful. i’d just put everything on a piece of mdf to protect the teeth from the CI table he’s using:
