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.
The edges of MDF are fragile, easily crushed or torn. MDF is also notorious for absorbing water through these edges, causing the panels to swell. In Sam Allen's original design, he edged the MDF with 1/4" hardboard. This edging is one of the complexities that Asa Christiana left out in his simplified design. I think this was a mistake. MDF really needs some sort of protection, especially on the edges.
Next is the shelf. Start with the 24x48" piece of MDF. Clamp this on top of the base, and pencil in the outside of the stretchers and the inside angle of the legs. Flip it over, pull out your trusty cutting guide, and cut it to width and to length. Cutting out the angles is simple, with a jig saw. It's not much work with a hand saw. If you took enough care with supporting blocks and stops, you could probably do it with a circular saw. Since I did have a jig saw, I used it.
The reason I'd cut out the rectangles in the vise support was that I'd intended to put a benchdog hole through each, and I wanted the thickness of the top to be the same for all of the benchdog holes. Where I messed up was in not cutting out the ends, between the bolt tabs. I'd intended to put a benchdog hole through there, as well, but I'd forgotten to cut out the segments prior to glue0up.
Dark colours appear heavier and create a feeling of stability, whereas light colours hold less visual weight and can appear unstable. When joining woods of dark and light colour, the visual effect of heavy and light suggest that darker woods work better when used on the bottom. A suggestion from my mentor to help getting proportions right was to spray paint mock-ups with a colour similar to the woods to be used later.
When the top is done, we want the edged MDF and the oak countertop to have exactly the same dimensions, and for their width to exactly match the width of the base.I could see three ways of doing this: 1, join the MDF to the countertop and use my belt sander to sand down their joined edges to match the base; 2, join the MDF to the countertop and use a hand plane to plane down their joined edges to match the base; or 3, use a flush-trim bit against a straight edge to route the MDF to the width of the base, then join the MDF to the countertop and use the flush-trim bit to route the countertop to match the MDF.
Put the countertop on the base, put the MDF on top of the countertop, and line up the marks you drew on each end of the MDF with the countertop below it. When you have it lined up, clamp things down, and route the edge of the MDF using a 1-1/2" or longer flush-trim bit, with the depth adjusted so the bearing rides on the countertop. I clamped a couple of scraps of doubled MDF at each end to give the router base something extra to ride on at the ends.
The engineering involved in building this garden bench is pretty simple, and we have provided some links to get a full cut list and plans with photos to help you along the way. Additionally, to the stock lumber, you will need wood screws, barrel locks, and hinges to complete the table. A miter saw or hand saw is also extremely helpful for cutting down your stock to the correct angle and length.
You are absolutely right on your advise. When I was agonizing over how to build a workbench my good friend turned me on to your book on workbenches. I was planning on having an overhang until I read your advise about building a workbench and not a table. So the entire front and rear surfaces; top, legs and bottom shelf are all in the same plane to clamp my work to. The addition of a sliding dead man was also something that I would have never thought of on my own. Thanks again for your advise.
“This hardcover book with internal spiral binding is 6.5in x 8in, a perfect size for carpenters and woodworkers to keep near their workbench or toolbox for quick access.The design of this book allows it to lay open flat, which allows for easy and frequent reference, and the interior photographs, illustrations and diagrams, make the learning process simple and fun for beginners, and provides useful tips for more advanced readers.
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.
Of all the machines in a workshop, we think two deserve their own books, not just because they possess the greatest potential, but when used incorrectly, are most likely to bite back. Bill Hylton and Fred Matlack’s Woodworking with the Router comes close to being the Router Bible. This tome provides an excellent overview of routers and bits while also explaining how to build and use jigs for router tables and handheld routing. Similarly, Paul Anthony’s Complete Illustrated Guide to Tablesaws gives entry-level and experienced woodworkers the information they need to safely use this workshop workhorse and accomplish more with their saws. Both books have excellent photos and great illustrations.
Workbenches have flat tops, though sometimes at the rear there is a cavity called a tool well that contains tools and components (and prevents them from falling off). One advantage of having the well set into the top of the bench is that, even with a variety of objects in the well, a large sheet of material can still be laid flat over the entire surface of the bench; the contents of the tool well offer no interference.
There are a number of tricks to using a router. First, the bit spins in a clockwise direction, as you look down at the router from the top. This means that when you cut with the router from left to right, the bit will tend to pull the router away from you, and when you route from right to left, the router will pull towards you. So, if you're hooking the edge guide along the near side of the board, route from left to right, and when you're hooking it along the far side of the board, route from right to left. Second, always test the position of your bit on scrap material. Your odds of getting it exactly right by eye are nil. Third, don't cut more than 1/4" deep on a single pass. We want a 3/8" deep grove, so make your first pass at 3/16", or thereabouts, and make a second pass to reach the full depth.
With the top laying on the floor, bottom side up, the next step is to flip the base upside down, and attach it to the top. I followed Asa Christiana's design, in using s-clips. When I stopped by my local Woodcraft, though, they only had two packages of ten, so I didn't use as many as I would have, otherwise. For the top I put four on each side and two on each end. For the shelf I put three on each side and two on each end. If it turns out that I need more, I can always add more.
One aspect of the Windsor Design that is hit or miss is the vice. Notice we have to use the singular when describing it because this is the first workbench that we have reviewed which features only one vice. To make matters more frustrating, the vice cannot be repositioned along the bench. That said, the vice does at least have the largest capacity out of any we reviewed. At 7” capacity, the Windsor Design vice can secure any size workpiece you may have.
