20-degree leg angle but also their 5-degree splay. Cut and fit the ties and braces, half-lapping the tie ends where they lap over the legs, notching the brace end lo fit over ihe lie. and notching the beam to accept the brace end. which is cut off at 55 degrees. Once the A-frame pans are cut and test fitted, drill for the various assembly bolts (Yl and for the lag screws ('/.) that anchor ihe braces to the beam. All the carriage bolts and nuts are V18 thread, with the boll lengths ranging from 10 in. on down to about 2*/a in. You may find il easier to just buy 1(1 in. long bolts and then use a hacksaw to shorten them to the sizes required. Note that we've counterbored a pocket for the nut and washer on each assembly boll. gltOMT V1E.VM Swing Hardware Whether you hang the swing from a beam on your porch, a beam in your living room (yes. some folks prefer a swing to ihe couch!), or ihe beam on the A-frame, the hardware required is the same. You'll need a bom 15 ft. of machine-link chain (St. which is sold at most hardware and building supply stores. But rather than just buying a 15 ft. length and then culling the chain yourself, take advantage of the cutting apparatus al the store to have the chain cut into the exact lengths required. As shown in Fig. 3. you'll need two pieces each in three lengths—27 in.. 24 in. and 36 in. You'll also need six connector links (Tl, four 4 in. long b\ s/u.-!8 eye bolts (U). eight matching nuts (V) and eight washers (W). We've given the washers and nuis separale pari numbers, since there are not just one each, but a pair of nuts and washers on every eye bolt. The lag hooks (X) screwed into the bottom edge of the beam hang the sw ing. Finish Our swing was finished with several coals of a marine-quality spar varnish. But keep in mind that even the best spar varnish won't last forever, so you'll want to store your swing inside during long periods of inclement weather. The A-frame was painted wilh an opaque slain, lo mute ihe unpleasant greenish tone of the pressure-treated wood. ftJi May/June IW3 53 |
