I'm building a cart to hold my 60 lbs mitre saw. I'm using 3/4" Sande plywood. I plan on building the box using glued, pocket hole butt joints illustrated below. Keep in mind that I do plan on adding a shelf about 2/3 up from the bottom of the base.
My question is, which is the better design for the cart, given the weight that it will hold. Originally, I was planning on Option 2. However, every video and plan I can find for similar carts uses option 1. To me, option 2 puts less force on the joints themselves and takes advantage of plywood's great compression strength qualities. Whereas, option 1 puts a lot of shear force on the joints. Maybe it simply doesn't matter and that's why I'm only finding examples of option 1. Either way, I want to make sure there's nothing I'm missing anything in either design.
