Topic tags/keywords: design dado rabbet

How deep should dado/rabbets be in a side panel of 3/4” plywood bookshelf? I wasn’t sure if there is a rule of thumb to follow when determining the depth of the cut.

3/8”. rule of thumb is the depth of the dado is half the thickness of the side.

I always teach 1/3 the thickness. I’d be interested to see what A1Jim does on his. A tie breaker? :)

Yeah, i’ve always done about half the thickness…are these dados to hold the shelves?

I agree with ,,rance
a quarter inch deep dado (in three-quarter inch stock )will hold the shelves fine, and not weaken the sides
But once it is glued up, it probably doesn’t matter
The two bookshelves I built the dado’s were, one third the thickness of the sides

I’m in the 1/3 camp. I use a router with a template bit and jig. Rout back to front, turn off router at end of cut and remove. Do not back out, the joint won’t be has tight. I don’t cut all the way across the sides because I round over the front edge of the bookshelf.
