When you have the other leg seated, the threaded rods will extend father than you want them to. You'll want to mark them so they can be cut to length. Place a washer and a nut on each threaded rod, and then tighten down the nut to pull everything tight. Depending upon the wrench you are using, and how much longer the rod is than it needs to be, you may find it necessary to stack up a number of washers, so that the nut is positioned where the wrench can operate on it.
You can bookend my 30 years of woodworking with two volumes. Roy Underhill’s “The Woodwright’s Shop: A Practical Guide to Traditional Woodcraft” (U of North Carolina P) marks the beginning. Today, Steven W. Semes’ “The Architecture of the Classical Interior” (Norton) makes sense of all the conflicting mishmash of “design speak” tossed about. Hope I have another 30 years in me so the Semes book will someday be a midway milepost in a long, rewarding journey.
If you’re more interested in working with wood rather than machining it, you will be relieved to learn that expensive powered machinery isn’t required to build furniture. You can also forget the dust masks, face shields and hearing protection since many of the safety concerns related to woodworking—the use of power tools—are eliminated. In this book, you’ll learn to set up a hand-tool woodworking shop, then discover the toolset, practice the skillset, and understand the mindset—effectively completing a comprehensive course in hand-tool woodworking.
I used the factory edge of the half-panel of hardboard as a guide for cutting the ply. I wanted to cut a 5-1/2" strip, and my saw cuts 4-1/2" from the edge of the shoe, so I wanted the edge of the hardboard 10" from the edge of the ply. So I set my combination square to 10", and used it to mechanically set the distance. Hint - if you need two things to be precisely the same length, try to avoid measuring them separately. Use some mechanical mechanism for setting the distance.
