A shed is a great project to earn your sawdust legs on. It is just some very basic carpentry skills. You could build the whole thing with a circular saw, hammer, utility knife, pencil, and tape rule. Find a friend or relative that has some decent skills to help. You could do it in a weekend. Keep the size on a four foot increment to minimize wastee. I would recommend a 12 x 12 or a 12 x 16 if you can. If you don't want to cut any rafters (which is really a simple process), you can order small triangle shaped trusses for the roof from your local lumberyard. If you are using T1-11 for the sides, get the real plywood based stuff, no waferboard. Same thing for the floor, use plywood (treated if you like). Cedar for the trim, not pine. The visqueen underneath is a good idea. Insulate the walls inside to help temper temperature swings. Build overhanges into the roof all the way around, 12" is nice. These really are a fun project. You can add a small window with a flower box underneath to make it look a little homey too.
Synopsis: No room in the garage? Basement not an option? Consider what Ken St. Onge did when he needed shop space: He bought a prefabricated shed and converted it into his full-time woodshop. Because a pre-built shed doesn’t need a cement foundation and is built in a factory, it’s much less expensive than building an addition or stand-alone shop on your property. It can have taller ceilings than a garage and bigger doors than a basement, both big pluses for a woodworker. You can put a shed just about anywhere, too. Here’s a soup to nuts look at Ken’s experience, so you can gauge whether a shop in a shed is right for you.
Regardless of which type of screw you use, you'll need to flip the panel and use a countersink drill to on all of the exit holes. Drilling MDF leaves bumps, the countersink bit will remove them, and will create a little bit of space for material drawn up by the screw from the second sheet of MDF. You want to remove anything that might keep the two panels from mating up flat. I set a block plane to a very shallow bite and ran it over what was left of the bumps and over the edges. The edges of MDF can be bulged by by sawing or just by handling, and you want to knock that down.
Some tools required for this project are hole saw, drilling machine, pencil, tape measure, clamps, etc. This tutorial explains every step properly with images so that anyone can make a wooden sofa sleeve easily. Those, who prefer a video tutorial, can visit the below link to a YouTube video that illustrates the process of building a DIY Sofa Sleeve Cupholder.
If you're using drywall screws, you'll want to countersink the holes. Drywall screws are flat-head, and need a countersink to seat solidly. If you're using Kreg pocket screws, the way I did, you won't want to counter-sink the holes. Kreg screws are pan-head, and seat just fine against a flat surface. Both drywall screws and Kreg pocket screws are self-threading, so you don't need pilot holes in the second sheet of MDF.

I know, if you had a workbench, you wouldn't be building a workbench. Even so, you'll need some sort of work surface, even if it isn't as stable or capable as a proper bench. The traditional solution is to throw a hollow-core door over a couple of saw horses. The advantage of hollow core doors is that they're flat, stiff, and cheap. I used a folding table and a hollow core door I had bought for a future project.

Learn how to use power tools, as well as traditional and modern hand tools, safely and effectively. Class assignments introduce basic concepts and techniques, to give you the skills needed for many woodworking projects such as mill board flattening and straightening, creating strong joints for connecting wood, and gluing boards together to make a panel. Students leave with a strong foundation for more advanced wood classes and a small end table. All tools for learning are provided.
I agree that even at 12x12, things'll be "cozy" inside. That's OK. Keep in mind that this will be a general purpose hobby shed, not just a wood working shed. Even 12x8 would be plenty big enough for building 1 meter wingspan bungee launched RC gliders. And for the electronics projects I do, I only need enough workbench space to do some soldering with a 3rd hand (for electric guitar pedals). If I need more room than the shed offers for wood working projects, I'll just roll the table saw down a ramp and do my cutting outside in the sun.
Have you got an old whiskey barrel at home that you haven’t used for ages? If yes, this project is for you. You can make a really beautiful coffee table from that old whiskey barrel in a few easy steps. Apart from a coffee table, whiskey barrels can also be used to build several other furniture items. But that is a talk for later. Here, we will discuss how to make a coffee table from a whiskey barrel.
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.

Much like the dimensions of a bench’s tabletop, the weight capacity will similarly affect what size of projects you can work on with your bench. A common weight capacity sits between 220 to 250 pounds. While this is okay, it will limit some heavier projects. Ideally, you should shoot for 300 pounds, though some benches can offer 500 pounds of weight capacity or more.

In the middle third of the course, you’ll build a tool tote that features dovetails joining bottom-to-end boards; rabbeted and copper-nail pinned side boards; shaped end panels and curved handles passing through angled mortises. This joiner’s tote also features a lift-out box for layout tools with lapped (or optionally dovetailed) corners and a sliding lid.
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.
