The top is supported by the top ends of the legs and the top sides of the top stretchers. Stand your legs on end on a flat surface (like my door) and see if they wobble. If you have an end that isn't quite stable, use it as a foot, where the leveler will make it's flaws unimportant. Check the top edge of each stretcher for straightness. If one has a bit of a bow, use it for a lower stretcher. It's less critical that the shelf be well supported along its length.
I love the opportunity Community Woodshop provides to take advantage of the tools, high-end equipment and hands on skills they'll assist you with when working with woods and metals. I'm not too sure about the Community part because I'd probably not come back because of the distance, however I do recommend learning to build shit on your own rather than paying a hefty price for the same materials that all furniture and fixtures and most jewelry are made of. They offer a wide variety of classes that teach you skills to build different items and use different tools.
I’ve seen antique cabinetmakers’ benches that are sixteen and seventeen feet long, more than three feet wide, and supported by a dozen drawers and doors—and that weigh as much as a felled oak tree. In contrast, jewelers’ cabinets seem to be on a dollhouse scale, with tiny tools to match. For most of us, however, space limitations preclude the biggest, and the smallest are just not big enough.
The first time you try your hand at the ancient craft of woodworking, you want to do it right. Learn woodworking basics with hand tools to a professional standard on a weekend woodworking course at Rowden Atelier. Ed Wild runs weekend furniture building courses for everyone from beginners who want to have some fun experimenting behind the bench, to those who are looking to develop specific skills as a furniture maker. Classes include tool handling, box making, and basic veneering, but to a certain degree, you can tell us what you want to learn - these short woodworking courses are partly bespoke.
@cahudson42 I bored the holes in my sandwich top with a 3/4" power auger bit with the drill in a portable drill guide that kept it vertical and in a way a bit like a plunge router. The guide screw of the auger was dead easy to centre over the laid out grid points. The holes are dead straight and clean sided. The auger bit was new which probably helped. As stated I have three rows from an end vise running the length of the front as well as from the front vise and holes in the front apron to support long pieces as well.
Another odd design feature of the Windsor Design is its dog holes. While this bench provides a variety of dog holes and even offers numerous pegs and dowels to go along with it, the dog holes are not spaced as closely or with as much variation as you see with many other benches. Ultimately, this means that smaller workpieces may not be able to use the dog holes and pegs as well.
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.
