The bench I will be describing differs from both of these in a couple of areas, the most significant of which is the top. Allen's top was made from three layers of 3/4" medium density fiberboard (MDF), topped and edged with 1/4" hardboard. Christiana's top was just two layers of 3/4" MDF. My top is two layers of 3/4" MDF edged with 1/2" oak and topped by a 1-1/2" thick edge-glued oak Ikea countertop. My top is more expensive in both time and money than either Christiana's or Allen's. If you're looking to build something fast and cheap, I'd recommend Allen's approach over Christiana's. The hardboard significantly increases the durability of the top.
I ended up making a number of practice cuts. The first revealed that I hadn't tightened the screws on the edge guide enough. The second revealed that the design of the edge guide provided very little support at the end of a board, because of the cut-out for the router bit. In the "Getting Started in Woodworking" video, they had screwed a piece of hardwood to the edge-guide, to provide a continuous -- and longer -- bearing surface. I may do that myself, some day, but I didn't have the materials at hand, so I clamped some 2x4 scrap to the end of each board, to provide a continuous bearing surface past the ends. The two grooves in the long stretchers and the side groove in the short stretchers have identical layout. I made practice cuts in scrap until I had the edge guide set correctly, then I cut them all with that one setting. The bottom groove of the short stretchers uses a different setup, so it was back to the scrap, before cutting them.
Of course, I, on the other hand, with my Ikea oak countertop, probable went overboard in the other direction. Since I needed to trim the countertop to width,I figured I'd take off a couple of 1/2" strips to use for edging the MDF. I clamped the countertop to my bench base, and used the long cutting guide. I'd asked around for advice on cutting this large a piece of oak, and was told to try a Freud Diablo 40-tooth blade in my circular saw. I found one at my local home center, at a reasonable price, and it worked very well.

I would say take the shed, you'll find some use for it. I have contemplated this question also. I have a 20' x 11' basement shop, thats quickly loosing space. If you live in an area with a harsh winters (say the Midwest), does it make sense to heat the shop through the week if you are only working in the shop on the weekends? Or do you run the heaters just when you are working in the shop? What kind of heaters are recommended (radient, wood stove, etc.)?
My bench is MY BENCH. In other words, it’s a thing of evolutionary beauty. I built the top 10 years before deciding on and designing the base. I spared no absurdity. It is supremely stout and the much maligned drawers are accessible from either side. The larger drawers have dust lids and can be extended to provide support for large workpieces or as a step for climbing on top of the bench. The top alone weighs more than most Roubos. So NYAH! Did I mention that I designed it to fit in with the Arts & Crafts vernacular? Who said you can’t build your bench to be furniture? Beautiful as well as useful shop furniture? Just sayin…
Those bums even have a stipulation that you can't connect any utilities to a shed. My plan is to adhere to the letter of the law if not the spirit. I plan to run a buried 20 amp power line out to the shed (this will be done professionally and properly according to whatever is required by the law), but it will require a manual connection to a junction box on the outside of my house to complete the circuit. That way, I can argue that the electrical connection is only temporary and is little more than a safe and buried version of an extension cord.

I like the idea of re-inventing the wheel. I choose to believe that while others may have considered these improvements, they just never got around to trying them out. Brain gets bored with status quo. So, I try to keep Brain happy with the occasional foray into uncharted territory. And I must say Brain has had some really good results. Thanks, in part, to you, and the Roy. You never know where a good idea might come from so I’ll check in once in a while. That and make sure to build it in Sketchup first.
I’m building my second bench. I built the first years ago with wood from old machinery pallets – mostly oak and maple. Mortised the legs into the base, and pegged ’em with 1″ dowels. Of course, the legs warped a bit, but that made everything tighter and stronger. The top is 2″ thick Ash, one board cut in half and joined side to side. Wrapped a maple apron around the top, and I think I screwed the top from underneath to the leg braces. Solid. Over time, built a cabinet under for 3 drawers and a small cabinet door. Works for me.
I built my first platform bed by following the steps mentioned in the tutorial and the end result was everything I expected. It was as beautiful as comfortable and strong. It only cost me around $60 to build this one from the scratch. And if I can build it, anyone can. What you need is a little bit of woodworking experience and a lot of confidence. Collect the items as suggested in the video and start working now.
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.
