The main structural members are 3/4" plywood. I was planning to use either Baltic Birch or ApplePly.
The first image is a perspective on the "complete" plan; I didn't add drawers yet, again because I'd like to see if I want to change the plan first after feedback. The top is from a 1.5-inch slab benchtop I yanked from a Costco steel-leg workbench. Not really needed for a stand like this, but why not?
The second view has the top hidden, showing the frame beneath it (made from 3/4" by 3" stock); I'm planning on using loose tenons. Again, maybe not necessary, but good practice for my first serious project in quite a while, and first crack at loose tenons.
The third image is a flat-on view of the back. I'm rabbeting the sides all the way down (1/2" in), and currently plan to use 3/8" thick stock rather than 1/4" just for added strength. This view also shows the second frame, made like the top one but with the appropriate dimensional change. This sits under the bottom plywood piece, adding support and thickness for the roller wheels I plan to mount.
The last view is one of the sides. It shows the rabbet at the top for the frame inset, as well as the dado 3/4" up from the bottom for the inset plywood bottom piece. The bottom frame sits directly under the plywood bottom, and is not inset into the sides.
I spent a fair amount of time on this model, most of it fiddling around with precise positioning of adjoining parts. Two tips I can pass on which would have avoided 80% of this time: First, working in perspective is great most of the time, but switch to a 2-D view in order to line up parts in the same plane
. Second, when you're moving a part into place to align with its "neighbor," be sure to drag the part being moved by the corner that you want to "dock" to the other part(s).
I don't recall that being mentioned in the tutorials I watched, but it turns an imperfect 15-minute headache into a perfect 3-second operation. No kidding.
I'll look forward to any suggestions or comments... but for now, I'm almost as delighted as if I were displaying the finished product!
