Step 1 Using tape measure and pencil, measure and mark up sleepers in following lengths and quantities: 1400mm (2); 1200mm (2); 1000mm (2); 800mm (2); 600mm (2) – 1 of each length makes 1 set of posts.
Step 2 Use power saw to cut marked lengths to size. You may need to cut from 1 side of post, flip it over and finish cut from other side of post.
Step 3 Lightly rub timber lengths with sandpaper to remove splinters and smooth out any rough patches.
Step 4 Working with 1 set of posts on level ground, test-fit how they will come together, using main picture as a guide. To begin assembling groupings of posts, clamp 1 pair of posts with bottom ends flush, predrill, then secure together with an even spread of 2-3 bugle-head screws.
Step 5 Remove clamp, then bring in another post and clamp it in position to first assembly, keeping bottom ends flush. Predrill and secure post to assembly with 2-3 screws. Continue using this method to secure remaining 2 posts to assembly.
Step 6 Repeat Steps 4 and 5 to make second set of posts.
Tip Mirror the layout of sets of posts so they look even on each side of a sitting bench or entryway.
Step 7 Using straightedge and pencil, draw a cross from corner to corner on top of each post, to mark centre point.
Step 8 Measure length of shaft of solar lights, then use drill fitted with spade bit to drill a hole in each marked position to required depth.
Step 9 With post assemblies in desired position, insert a solar light into each hole, ready to shine when night falls.
