Place base logs (identified with a “B” designation) in the subfloor area for The sawn flat surface of the easy access. Most, if not all, of the base logs are bundled together in Bundle base log may vary, allowing #1. Refer to the bundle sheets to quickly find base logs. Base course logs potential variance in the are 5 5/8” high x 6” (approximate) width, with a flat surface sawn on the width of the base logs. For inside face of the log to provide for the construction of an electrical chase this reason, it is not (finished with furring strips and base trim by owner allowing for base trim recommended that the chalk variety). Base logs are set directly on the sub-floor, matching the center of line be snapped to match this the log wall to a chalk line marked on the subfloor. flat face. Always use the 2. Snap a chalk line 2" in from the edge of the subfloor around deck centerline reference. perimeter (Fig. 4-2). If the subfloor needs SLIGHT adjustment, you can alter the 2" dimensions slightly to make chalk lines square. This measurement allows the logs to overhang the foundation so that siding covering the perimeter sill will match correctly. (The ¾” T&G subfloor should be flush with the outermost edge of the perimeter sill.) Figure 4-2 Layout Using Chalk Line 3. Position Logs : First, measure and mark the base logs to reflect the centerline of the log wall. Measuring from the exterior crown (top) of the base log, put a pencil mark at 3¾” and extend it down to the bottom of the log using a carpenter’s square (Figure 4-3). Then, beginning at the front door, lay the base logs over the chalk line, aligned with the centerline mark. Move clockwise around the building perimeter, from left to right following the numbering on the log assembly overlays. Be sure locations of all door and fireplace openings are according to final plans. (It is possible to accidentally reverse a wall.) At door openings, use the top, or header portion of the door buck, as a spacer to insure correct spacing for base logs. Check the length of buck headers to be sure they are cut to the exact width of the door opening. (See Section 4.2 on page 4-8 after the First Course: “Install Door Bucks”). 4-4 © 2019 DIY Log Cabins, LLC DIY Log Cabins Construction Manual 4. Check Straightness : Stretch a string line between nails driven into the tops of the logs at either end of the wall (Fig.4-4). Use the string as a guide to assure that the log course is perfectly straight. If the logs have been positioned correctly and the subfloor is accurate, the base course should overhang the edge of the subfloor as shown in Fig. 4- 3. 5. Apply Sealant : Once you have verified that the base log course is accurately placed, move the base logs aside and apply construction adhesive between the subfloor and base log course to create a weather tight joint (Fig. 4-5). Apply 2 continuous beads at approximately 1” and 3” from the edge of the subfloor on both sides of the chalk line. Check for square and straightness, then set base logs back into their final position. Figure 4-3 Setting the Base Course Figure 4-4 Checking Straightness with a String Line 6. Toenail Joints : Toenail the logs together with 2-16d galvanized nails to tighten each butt joint and corner, being careful to avoid any log movement (Detail L-6, Pg. 4-36). The log overhang should be uniform all around the perimeter (see Fig. 4-3). Figure 4-5 Applying Sealant © 2019 DIY Log Cabins, LLC 4-5 4 Stockade Assembly 7. Install LogHog™ Fasteners : With the base logs sealed and in proper IMPORTANT! location, install LogHog™ fasteners in the base course and countersink heads Base log LogHog™ (screw down until tops of fastener heads are slightly below log surface) using fasteners should socket provided. Typical placement specifies 2 fasteners at each butt joint penetrate into triple and corner (Figures 4-5 & 4-7). This means that logs 24” or less in length 2x10 perimeter sill. should have at least four fasteners. Additional LogHog™ fasteners are In the unlikely event positioned every 36" on center and staggered, or altered from inside to that a log should outside of log (Figure 4-5). For logs over 24” but less than 72” in length, 2 need to be removed, fasteners staggered in the center third of the log are recommended (minimum (maybe the wrong of six fasteners). (Detail L-5, Pg. 4-33) log was fastened in by accident), the LogHog™ fasteners can be removed by reversing your drill and removing them. Figure 4-5 Setting LogHog Fasteners in Base Course When fastening the logs, alternate sides of the log when installing the fasteners. Fastening completely down one side first will tighten that side but may create a gap on the other side that does not pull completely together. This results in a log that is not seated flat. Left uncorrected, successive courses of log will tend to roll, and it will be difficult to bring the wall back plumb. When detected early, shims or washers may be used to lift one side of a single course to correct roll, but this is not recommended as a common practice. 8. Install Dowel Pins : After all LogHog™ fasteners have been installed and tightened, drill 1” holes approximately 6" deep (stack height of one log) at each butt joint (Figure 4-4) using a 1” wood drill bit (NOT SUPPLIED). Figure 4-4 Drilling at Butt Clean away sawdust, fill 1/4 to 1/3 with caulk, and hand press dowel pins Joint for Dowel Pin into each hole so that the top of the dowel is slightly lower than the top of the logs (Detail L-6, Pg. 4-34). 4-6 © 2019 DIY Log Cabins, LLC DIY Log Cabins Construction Manual 9.
