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.
There is a mandatory safety class you have to take where they walk you around the shop and make sure that you know how each major machine works and general shop safety. You also have to sign a waiver saying you are participating at your own risk. You DO NOT have to take that safety class if you are signing up for one of their classes. They will cover those basics during the class.
One you have the vise jaws shaped so that the vise moves freely, mark and drill holes in the fixed jaw for the bolts that will hold it to the bench. With these drilled, reassemble the vise and mark the location of the holes with an awl. Disassemble the vise and drill the holes through the stretcher, then reassemble the vise and bolt the inner jaw in place.

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.
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.
Fundamentals Of Fine Woodworking With Taeho Kwon (Evening Class) The secret to fine woodworking can be found in the pursuit of the fundamentals. With high-tech machines and power tools, these fundamentals can be overshadowed. In this class we will learn the values of design, drawings, mock-ups, sharpening, care and use of hand tools, tuning up a bench...
You may even want to put yourself in the picture. If your workshop space already exists, find a large piece of cardboard, wallboard, or plywood that’s about the size of the workbench top you envision. Find a couple of stools or chairs, perhaps a few books, and turn them into stanchions to support the “benchtop.” Is it too big for the space? Is it large enough for the tasks you envision will be performed upon it?
After I left the magazine for a new job, I did all of my woodworking in my small two-car garage, but it was a struggle. Power, lighting, and temperature control were limited. And because I shared space with our cars I was always moving machines around, often while in the middle of a project. On top of that, my tool and machine collection had long since eclipsed the space. For all these reasons, fixing up the garage wasn’t an option. My finished basement is a family room, so it was out, too. An addition to the home or a stand-alone building would have been too expensive. I had to find a better path to a shop.
