The holes we want to mark are the holes through which the threaded rod connecting the two legs will run. This threaded rod will run through the 3/8" groove along the bottom of the short stretchers,. The hole for the upper stretcher has to be positioned so that when the rod is running through this groove, the top of the short stretcher is even with the top of the legs. The most precise way I've found for marking the position of this hole is to use a dowel center. Fit the dowel center into the bottom groove, line up the stretcher, and bang on the end with a rubber mallet. The dowel center will leave a mark indicating the center of the hole.
This is my first post here but been lurking for a while. I am currently working in a 10x14 shed which has sufficed nicely until my recent purchase (sunday) of a new Craftsman table saw model OR35505. This I discovered ate a lot of space but with some reorganization and some good casters, it's going to work. I did add a window AC unit and will need to figure out some heat but hoping to have built a better shop with HVAC before it's too cold.
I live in VA and my workshop is an unheated, uninsulated garage. I work out there year round, even when temps are below freezing. I can't say it's comfortable in the winter (or when it's 100 degrees with 95% humidity) but I haven't had any major issues. I have had some big box green wood warp on me after I built a couple bookshelves and brought them into the house, but that was more a factor of the green wood than my "shop".
If you bought this superb polished table in a store, it would cost you a fortune, but our detailed instructions will help you make one for less than $100. And it looks like highly polished stone, but no-one would know it’s actually made from concrete with a wooden base. Also, you can embellish the top with leaf prints, like the table shown here, or personalize it with glass or mosaic tiles or imprints of seashells.

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.
