Finger Joint Question.


I have a question about finger joints. I have an extreme limited exposure to woodworking. However there are a few projects I would like to try. I have read some of the sites and even watched some of youtube videos. There is one project I would like to do which requires 3/4 inch wide finger joints (making a beehive box). However the table saw I will have access to will only cut a max of 1/2 dado cuts. People have mentioned making two passes but never went in to detail of what is require. Can someone give me a little more detail on how to do this?

Thanks for any input,

Well, there is one easy way to do it; make the project with 1/2 fingers instead of 3/4.

Seriously, I'm not being sarcastic, trying to cut a finger wider than your cutter is going to require a much fancier jig than your standard box joint jig, and multiple setups means increasing the number of chances for something to go south. If your parts can be divided by .5 evenly, use 1/2 fingers, if not, use 1/4

I'm not understanding the limitations of your saw. If your saw will only raise up to a height of 1/2" it would make thinks simpler to make the box out of 1/2" material. If though you can raise the blade up to a height of 3/4" then the smaller the dado you use the better. It would make more pins making the joint better. 1/2" wide would do you fine.

On a joint like that the height of the dado is usually set at the thickness of the material you are using.

height vs width

As suggested the height should be the stock thickness. The width can be the maximum of your dado capability on your saw, OR your router bit width. It's a personal choice, but equal width and height fingers may look better to some folks than to others. However, for your beehive box, I'd make them all the same for simplicity sake.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)
