I have a couple of questions about dado sets some of you more experienced woodworkers could answer for me! I have a generic Craftsman 10" table saw that I want to add a dado set to. I found in the operators manual that I have to use a 6" NON carbide tipped, Non adjustable 1/2" wide max dado! What I need to know is what a "non-adjustable dado is, never heard of one! What is the reason I can't use carbide tipped dado sets. Also, why only up to 1/2" width, looks like there is plenty of clearence for a wider set! While I'm at it can you tell me the benefits of a "wobble" dado over a stacked dado! Any other comments about what to look for would be appreciated too!

Best regards, Joe
