Assembling a Trestle Section Construction Jig To accurately position the bents I created a construction jig. I created a full-size CAD drawing that I had printed at Staples as shown in Figure 1. The bottom view is the one I will use to position the bents properly, as I am building this “upside-down,” much like […]
Part 5 – Building the Beam Assemblies The Beam Assemblies There are two beam assemblies each made of eight 3/8” x 1½” beams spaced equally with angled braces as shown in Figure 1. These rest on short bents attached to a full-height bent. Bents #8 and #12 rest on these beams. Two additional beams run […]
Odd-sized Stories and Bent Assemblies After a break for the Holidays and the generally unpleasant freezing weather, I’m back at it. In this installment, I’ll be building the odd-sized stories, adding the mud sills and assembling complete bents. A spreadsheet was used to calculate the height of the bottom story for each bent, as I’m […]
Mass Production of Bent Stories To efficiently build a large trestle such as this, I will take advantage of the many identical assemblies of bent stories. Of the 20 bents, four are less than full height. I’ll handle exceptions like those individually. In this article I will describe how I build the bent stories in […]
