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.)?
First, we need to drill out the holes for the screws that will hold them together. While the two layers of MDF are glued, the countertop and the MDF will only be screwed. The oak countertop, like any natural wood product, will expand and contract with humidity changes. If it were glued to the MDF, the difference in expansion of the two layers would cause the countertop to buckle and curl.
The end vise will have both jaws made out of 1-1/2" thick oak. The front vise has its moving jaw made of 1-1/2" oak, but uses the edge of the bench as its stationary jaw. So while for the end vise, if we mount it lower, we can make both the jaws deeper to compensate, for the front vise we cannot, so we want it mounted as close to the edge of the bench as possible.
This trade and technical college currently serves over 15,500 credit students from its campus in downtown Los Angeles. Through the Construction, Design and Manufacturing Department, full-time students can enroll in a daytime certificate or an Associate of Science program in cabinet and millwork. Evening programs for current craftspeople include a certificate program in construction technologies and an Associate of Arts in cabinetmaking and millwork that provide students with the skills they need to work in construction or manufacturing.
I live in the second rainiest city in the country, Pensacola, so I am used to dealing with wet. I literally work out of my garage (read storage area, small woodwork area, washer/dryer...car? ). I wheel bigger tools and table out to the little covered area in front of the garage. I have an 8 x 10 aluminum shed that is strictly garden stuff storage. I mention this for two reasons.
Frame making may look simple but it is a skill that escapes many. For a frame to properly do its job it has to be perfect, any mistake can be a distraction that takes away from the artwork it surrounds. This class will focus on skills essential to making square or rectangular frames. Skill building concepts will include how to break down and mill...

Students will make two pens at the lathe, one of solid wood and one of your own design built up from several pieces of wood. Since turning pens is a quick process, we will have time to teach you how to choose woods, how to prepare and mount wood on the lathe, and several of the more popular finishes. We will cover safe operation of a lathe, demonstrate how to use common woodworking tools, practice tool sharpening techniques, and discuss options for what kind of lathe you might want in the future, from a small pen lathe to more robust machines that can handle much bigger projects. Bring clothes that can get dirty.
As I was handling the 2x4's, during the routing, I realized that I really wouldn't be happy with the look of the bench, if it were made from these unfinished boards. They had stamps, pencil marks, and more importantly, incipient splinters left by the saw, none of which I wanted. And I was remembering what other shop furniture made from unfinished pine had looked like, after a few years in the grime of a shop.
I don't see anywhere you mentioned the over all length of the bench top. A piece of 1 1/2" x 25" x 8' glued edge oak at Lumber Liquidators costs $192 including tax. Two piece is almost $400! Would that be better if I use two IKEA 1 1/4" x 25" x 74" solid Beech ($99 each plus tax) on top of a layer of 3/4" Birch plywood. That would be 3 1/4" over all.
My first attempt at making a cutting guide didn't work. What I ended up with worked fine for cutting panels, but the guide-strip was too narrow, and when the saw was extended fully for rough-cutting the 4x4's the clamp heads got in the way. So I made another. Actually, I made two more, so that I could cut one into shorter pieces that would be easier to handle.
Remember those fire safety tips you used to get in grade school, about the dangers of oily rags? It was linseed oil they were talking about. All oily rags are dangerously flammable. Linseed oil will self-combust. Linseed oil doesn't evaporate, it oxidizes. The oxidization generates heat, and the increased temperature increases the rate of oxidation.
The source above is not exactly a tutorial, but it gives you a basic idea of how the author built a Quirky Pallet Art to enhance the look of their old house. You can also find another tutorial at the link below. It shares a step by step procedure for making a wooden pallet sign. The final product is not exactly the same as the one above, but the basic idea is the same.

From the image above it seems that you do not require a big tutorial to help you to build this candle holder. All you need is a wood panel, a hook and some nails/screws and do exactly what you see in the picture. Attach the hook to the wood panel using two screws and then, attach the panel to the wall using more nails or screws. That’s it. I hope this gets the job done.
I marked out the one hole location, drilled a shallow 1/16" hole into the top. I then put a 1/16" bit through the hole in my template and into the hole I had just drilled. I lined up the template, and drilled a second hole, then put another bit through that. From then on, I worked entirely from the template. With two bits through the holes pinning the template in place, the other holes in the template would be precisely located (or so the theory goes) on a 4x4" grid.
I decided to finish the top with a number of coats of Danish oil, followed by a coat of wax. I applied the first coat of oil in the usual manner, making sure to cover the edges, and down the holes. I applied a coat oil to the top side of the shelf, as well. Wipe it on, let it sit wet for half-an-hour, then rub it off. Wait a day or two, add a second coat, and then again for a third.
In each Practical Woodworking Class, the daily mix consists of intensive lecture, demonstration, and student practice lab time.  Lecture periods are interactive, informative, and intensive but are also an enjoyable experience.  Generally, each joinery and fabrication process is demonstrated in several ways to reach or achieve the same results.  For example, processes are first demonstrated with the use of hand tools. Next, the same joint or procedure is done with simple hand held power tools (such as the router). Then, the entire process is demonstrated with stationary equipment such as the table saw, drill press, and mortiser. Students choose whichever production method works best for them and is in keeping with their plan to equip a home workshop and/or around their existing home tooling.

Thanks Chris! I found this page while looking for a link to your e-mail address. I recently finished your erudite volumes on workbench design, and am about to embark on my own bench inspired by your take on the Holtzapffel design. As my vices and planer arrive, I’ve been agonizing over whether to use SYP or rough maple for the top. I don’t have a big budget, so all-maple is not an option. But after reading your ten tips here, I’ll stop agonizing — all SYP it is! This is, after all, my first of what I hope are at least several handmade benches. Your scholarship and craftsmanship are truly inspiring.

Get perfectly, consistently spaced and centered shelf-pin holes! Economical and practical, this jig can be used on assembled or unassembled cabinetry. Re-designed handle includes two storage compartments for self-centering bits! Ideal for adding shelves to new or existing cabinets. Drills holes either 1-7/16" or 2-1/2" from edge. Insert shelf pin in top or bottom position to extend jig for continuous drilling. Shelving Jigs measure 20" long Additional Self-Centering Bits available. 

Put the upper panel of MDF on your glue-up surface, bottom side up. Put the bottom panel of MDF on your other surface, bottom side down. (The panel with the holes drilled in it is the bottom panel, and the side that has the your layout diagram on it is the bottom side.) Chuck up in your drill the appropriate driver bit for the screws your using. Make sure you have a freshly-charged battery, and crank the speed down and the torque way down. You don't want to over-tighten the screws, MDF strips easily.
 I have always wanted to share this wonderful woodworking world with like-minded people from all over the world. For the last six months, I have started sharing Japanese woodworking information through videos and photos. Because of the huge amount of interest, I started organizing one-day workshops for people visiting Kyoto, letting them experience Japanese woodworking tools.
An excellent introduction to woodworking is to use crates as your main material. The boxes are already formed, which means less assembly work for you—yet it looks impressive once your project is altogether. With this crate coffee table, you still get to practice your skills adding the casters and the center box. Finish with a little stain, and this table is ready to roll. You can find the full tutorial at DIY Vintage Chic. 

I agree that I might quickly outgrow a 12x8 shed. Lowes also offers a 12x10 Rancher (same style, but more room), but the 12x10 is 9 feet, 4 inches high, and my community only allows a maximum height of 9 feet. The 12x8 is exactly 9 feet high. I'm afraid of getting "out of spec" if I exceed the height limit and then getting in trouble with the Home Owner's Association. Having said that, 12x10 would be about the biggest size I could get for the available area in my back yard, so even if I hire a shed contractor to do this, the shed would have to be 12x10 or smaller.
