These sorts of things are usually glued and screwed, but it's actually the glue that holds them together - the screws just hold everything tight while the glue cures. Screwing into hardboard or 1/4" ply is an exercise in futility, so I just used glue, and used my two 4x4's as long clamps. It would have been a bit easier, if I'd done this before I'd rough-cut the 4x4's, but it worked out.
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.
Of course, few benches can be ideal, and this one does have some drawbacks. That being said, most of the disadvantages of this bench are minor annoyances rather than deal breakers. For instance, this bench does not include any kind of storage whatsoever. Though, it does have the option of adding numerous additional features like a storage area. Still, for the bench, you would expect a drawer at the very least, maybe a shelf below the main table area.
Mine is similar but a bit more robust. The top is a sandwich, two 18mm sheets of WBP ply with an 18mm mdf filling. The legs are mortise and tenoned together, the ends glued and pegged, the stretchers are joined with long bolts so it comes apart. I stiffened it by adding a very closely fitted cabinet underneath (it had to go in dead square) and it is now absolutely rock solid.
Require the woodworker to be able to read the plans and to transfer images and dimensions from the plan to the lumber. The wood has been planed and all glued panels are completed unless over 14 inches. If panel required is over 14 inches, one glue seam will be required. The woodworker needs to be able to do some cutting, jointing, assembling and finishing. White Kits do not require planing. White Kits supply all of the needed hand-selected dimensioned lumber, but woodworking knowledge and tools will be useful to complete the project successfully.
Right now, there is a revolution in woodworking courses created by the closure of many state-run colleges. Our workshop has led the way and been the model for many of the private furniture making courses available to you today. Rowden Atelier is recognised as a Centre of Woodworking Excellence that produces exceptional furniture and trains exceptional woodworkers. With our range of specialist woodworking courses, you could be one of them.

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.
For most of the course, we'll be heavily focused on developing your skills using hand tools. As a developing woodworker, there is no substitute for putting in the hours of direct hands on practice it takes to gain an intuitive understanding of wood. The early part of this course focuses on working with hand tools as we believe they bring you closer to wood as a material.  You can rip a board on a table saw with out much thought to the wood itself, but you will understand much more about grain if you rip a board with a hand saw.  As the course progresses, machine processes are introduced as a pragmatic aid in expediting projects.  
I am new to woodworking. I'm learning as I go along, and I'm documenting as I learn, in the hope of being helpful to other novices. On the range from slap-dash to deliberate, my method is definitely on the deliberate side. If you have enough experience to be confident in using techniques that are more time-efficient, go for it. The techniques I'm using are those I thought least likely to go wrong, not those that would produce a product in the shortest time or at the lowest cost. You'll notice that I made a number of mistakes, spent considerable time on work I later determined to be unnecessary, and in a number of cases I used different techniques at the end than I did at the beginning. These are all the result of learning. I thought it would be better to demonstrate how I made errors, and how I corrected them, than to provide a set of instructions that presented the false impression that everything went together perfectly.
You can buy sandpaper, glue, and other consumables from them for a nominal price. Their hand tools are propitiatory though so you would have to buy a specific kind of orbital sandpaper, for example. You couldn't just get generic. They are reasonably priced though. There is literally a coffee can with money in it and prices written on the boxes with these consumables. If you think you might burn through enough sand paper on something, check the brand and price shop.
Had a great experience at the shop! My schedule is hectic and unfortunately can't make the classes, but I did do a private lesson with Bob.  In one afternoon, we created two cutting boards.  Bob was very detailed with breaking down the process and using the machines.  Honestly didn't expect to make two cutting boards but Bob was proficient with time.  I got really comfortable using the machines especially the table saw.  I learned how to use the planer, jointer, miter saw, table saw, drill press, router, disk sander, and random orbital sander.  Really recommend folks that are interested in woodworking with little to no experience to take the Safety Orientation and the Cutting Board class or private lessons.  Looking forward to my next project at the shop!
Let me see if I can come up with a couple details. The table saw is a TS3660. So I have heard, this should be the center of your shop. My jointer is a 6 1/8" Jointer / Planer JP0610 which is 45 inches in length. My router table is the kreg router table that takes up a 24 x 32 inch footprint. My bench is roughly 30 x 70 inches and my bandsaw is 3' x3'. I have other tools as well such as a portable 12.5 Delta thickness planer in addition to a wall mounted dust collector. To add to the list, I am just about to get a 10 inch makita sliding compound miter saw. I can see how space will be eaten up quickly. Any ideas as to how arrange these tools in such a small shop? I will get pics a soon a I
The next day, cut it flush. Use a block plane to ensure it truly is flush. This will be the top of the bottom layer of the bench top, so gouges aren't a problem. (Wiping up glue with a damp cloth can lead to stains and finishes applying unevenly. That won't be a problem here, either.) But bulges and bumps are a problem - they will keep the two layers of the top from matching up evenly.
The last thing is to semi-permanently attach the bolts for the vises. Given the amount of work necessary to get to the bolt heads, once the top is joined, I had intended to tighten them up so they wouldn't spin, and lock them that way with blue Loctite. (That's the strongest non-permanent grade.) That didn't work. What I found was that the bottoms of the countersinks weren't quite flat, and when I tightened the nuts down that far, the ends of the bolts would be pulled far enough out of alignment that the vise bases would no longer fit. In order for the vises to fit over the bolts, I had to leave the nuts loose enough that the bolts had a bit of wiggle - which meant that they were almost loose enough for the bolts to spin. So I put Loctite on the nuts, to keep them from unscrewing, and filled the countersinks with Liquid Nails, in hopes of keeping the bolts from spinning. I considered using epoxy, or a metal-epoxy mix like JB Weld, but I didn't have enough of either on hand. It seems to be working for now, though the real test won't be until I have to take the vises off.
In this class, John will explain and demonstrate safe spindle turning techniques for turning a bud vase or a carvers mallet, an essential tool for anyone wishing to sculpt wood or make hand made joinery. Objective Through hands-on learning students will gain experience and confidence using our new Laguna mini lathes. You will develop an understanding...
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.
