Hi folks,

I am embarking on what is a big challenge for me, building a set of bookcases based on a Wood set of plans. I wanted to check in on something and see if I could get some help interpreting the plans before I get too far along. I’ll include pictures of the plans to try to make my question clear.

The bookcase is made from 3/4” oak plywood. The plans seem to be calling for a 3/4” rabbet on top of the sides (A) but if a 3/4” top (B) goes into that rabbet, wouldn’t that mean that the top (B) would be sitting proud of the top?

See this picture of the plans for what I mean. I inserted a red arrow pointing to the rabbet in question and the test next to it says “3/4” rabbets, 1/4” deep. I wonder if that is a mistake and it should read 1/4” rabbet, 3/4” deep?

Here’s a picture from the plans that show the cabinet top detail. From the picture it does look like the top is flush with the sides which, I think, would have to mean that the rabbet is 3/4” deep?

Any help is appreciated.

The “deep” is referring to the depth from the face of the board, as if it was laying on its back. Not from the top edge while standing upright. Think of it as a 3/4” wide dado, cut 1/4” deep into the woods surface, only it happens to be at the edge of a board.

Thank you! Once you explained that, I can see that it makes sense. Just routed all the dadoes yesterday and so far so good!
