Well, not these plans. You have the option of building a very functional and spacious lean-to shed on different foundations. Your foundation choices are: concrete slab, a wooden floor supported by concrete piers, or a wooden floor supported by skids. That lost option also means that your lean-to could be mobile as well so you won’t have to decide where you want to permanently put it.
The reason I'd cut out the rectangles in the vise support was that I'd intended to put a benchdog hole through each, and I wanted the thickness of the top to be the same for all of the benchdog holes. Where I messed up was in not cutting out the ends, between the bolt tabs. I'd intended to put a benchdog hole through there, as well, but I'd forgotten to cut out the segments prior to glue0up.
If you remember, when drilling the MDF I finished the holes from the other side using a Forstner bit. It made for a clean hole, but the positioning wasn't as precise as I really wanted. So for this, I decided to clamp a length of scrap MDF to the back side, and to drill straight through. My Forstner bits were too short, so I bought an extender. And then I found that the spade bits I was using gave a cleaner exit hole. Whooda thunk?
Next is the shelf. Start with the 24x48" piece of MDF. Clamp this on top of the base, and pencil in the outside of the stretchers and the inside angle of the legs. Flip it over, pull out your trusty cutting guide, and cut it to width and to length. Cutting out the angles is simple, with a jig saw. It's not much work with a hand saw. If you took enough care with supporting blocks and stops, you could probably do it with a circular saw. Since I did have a jig saw, I used it.
A better solution would have been to route a rabbet into the side, so that the added strip always had thickness. The way I did it means that the strip I glued in is very narrow, and hence very weak, at a certain point. In this case, that's not a problem, because it's going to be sitting under the countertop layer. I also noticed that because I had only clamped the strip down, and not into the edge, there was a noticeable glue gap where the strip butted up against the MDF. Again, in this application it isn't visible. But if I was doing something like this on the top of a table, I'd make sure to cut a clean rabbet, and to clamp both down and in.

Through demonstrations and practice you will learn how to build a Simple Table Top. Square wood using the Jointer, Planer and Table Saw, then learn how to use the Festool Domino Joiner to keep perfect registration during the glue up. This will be a group project where everyone will help build a single table top. The goal is to gain experience and confidence...
I love the opportunity Community Woodshop provides to take advantage of the tools, high-end equipment and hands on skills they'll assist you with when working with woods and metals. I'm not too sure about the Community part because I'd probably not come back because of the distance, however I do recommend learning to build shit on your own rather than paying a hefty price for the same materials that all furniture and fixtures and most jewelry are made of. They offer a wide variety of classes that teach you skills to build different items and use different tools.
If you bought this superb polished table in a store, it would cost you a fortune, but our detailed instructions will help you make one for less than $100. And it looks like highly polished stone, but no-one would know it’s actually made from concrete with a wooden base. Also, you can embellish the top with leaf prints, like the table shown here, or personalize it with glass or mosaic tiles or imprints of seashells.

As you can see in the image, this shelf goes on both sides of the corner wall. It looks beautiful and can be used to organize books, trophies, pictures frames and many other things. The strength and design of the shelf depends on how properly you build it. First time workers definitely need some guidance to help them with the process. Therefore, I am including this basic video that I found on YouTube that demonstrates the process of making corner wall wooden shelves.
Out of all the shed books I have read, this book stays by my side while I hammer in the yard. The book is well written by what appears to be a non professional book writer (A Good Thing). It reads as if you are getting advise in laymans terms from your neighbor "The Craftsman", a welcome change from the DIY books, that assume a level of expertese. The level of detail is high and discusses gotcha's, advise, and trade "secrets" that could have only come from years of personal experience building sheds.
