I just bought a dado blade set and going by the directions for a 3/4 dado it said for me to use the inside and outside blade and 4 of the 1/8 chippers,,which I did and it does cut a 3/4 groove but its not as tight as I like it to be,,im really new at using the dado blades,,so if anyone can help me get a tighter fit I really would appreciate it,,thank you

Hey Jeff, Most dado sets that I know of should have a set of shims. Try leaving out a chipper and use the shims to match the dimensions of your cut. I’m relatively new to woodworking, so others may have more practical ideas. Hang in there. Future replies to your topic probably will help more than mine. Good luck with your project and keep me informed.

The answers above solve the problem. If you have the 1/16” chippir, install it in place of one of the 1/8” chippers, then use shims to get the width to where you want it.

I’ve also found that I need to test a dado cut every time I set one up, even if I’m using the same set of blades. I’ve not figured out why there would be subtle differences in dado width for a given combination of blades but there have been. I now always make a test cut in the same material before cutting a project piece.

If your inserting 3/4” plywood into the dado slot, it will fit very loose. 3/4” plywood is a little thinner than 3/4”. Just a reminder.
