I am building some new cases and crates this summer for some quarter ton Prostar chainmotors. The crates will each hold one motor, and 4 crates will pack in a case. This is because sometimes they need to be divided up in a venue to speed things up, and we don't want to have to wait for one point to get going and have another waiting. So here's my question. The individual motor crates are being made of 1/2" plywood. I am dadoing the end pieces to receive the side pieces, and dadoing both to receive the bottom piece. Attached is a jpeg of what I'm doing. The question: Is 1/4" the right depth for these dados? Am I compromising the strenght of the wood too much by doing this? I would say critique the drafting as well, but this is highly internal use (I drafted it, I'm building it, I'm making the materials list and going on the trip to the lumber yard), so I don't have as high standards for this in terms of spacing out dimensions and making line thicknesses nice and whatnot with this drafting.
