Once the required length has been determined, the next step is to lay out the locations of the anchor bolt holes. 1. 2. 3. 4. 5. Use the following steps: Establish the building line points at each of the corners of the foundation. Pull a chalk line at these established points and snap a line for the location of the sill. Square the ends of the sill stock, (Stock received at jobsites is not necessarily squared at both ends.) Place the sill on edge and mark the locations of the anchor bolts. Extend these marks with a square across the width of the sill. The distance X in figure 1-2 shows how far from the edge of the sill to bore Figure 1-4.—Installing termite shields. the holes; that is, X equals the thickness of the exterior sheathing. After all the holes are marked, bore the holes. Each should be about 1/4 inch larger than the diameter of the bolts to allow some adjustment for slight inaccuracies in the layout. As each section is bored, position that section over the bolts. When all sill sections are fitted, remove them from the anchor bolts. Install sill sealer (insulation) as shown in figure 1-3. The insulation compresses, filling the irregularities in the foundation. It also stops drafts and reduces heat loss. Also install a termite shield (fig. 1-4) if specified. A termite shield should be at least 26-gauge aluminum, copper, or galvanized sheet metal. The outer edges should be slightly bent down. Replace the sills and Figure 1-3.—Installing sill sealer. 1-2
