Topic tags/keywords: dado blade

hello all
I have a question and i am in need of guidance. i am trying to use a dado set to make a 1/4 inch rabbet. I am having a problem with the setup. The outside blade of my dado set falls on the threads of my saw’s arbor. It is a older craftsman saw and the instructions state the maximum width which is 13/16 Surely it is not to wide as i am only cutting a 1/4 cut. my problem is the outside blade wobbles and gets off center making a poor cut. HELP!!!!!. This is driving me crazy any help would be greatly appreciated.

Sounds like your arbor is wore. The arbor should be a constant width from the base to about the very end. Does your jam nut turn on really easy and have a some play in it as you thread it on?

You may try a wobble type dado blade.

Hey, if your arbor is worn, as suggested, maybe you should opt for a router with a rabbeting bit installed…good luck!

Is that 1/4” the width or depth of your rabbet? If it’s the width, just use a narrower dado stack.

You should also check the diameter of your arbor in 2-3 places. If it’s tapered, or worn on one end, replace it ASAP.
