Here's how to make a merbau garden screen
Determine location and screen dimensions for your space, then adjust Components list (above) accordingly. Using chalk spray, mark location where both End posts will be installed into the ground. Remove pavers. Use post hole pincer to dig both holes to 1000mm depth. Repeat to dig a 200mm hole for the half stirrup anchor at the midway point between End posts.
Measure, mark, label and cut all components (see list above) with tape measure, combination square, pencil and mitre saw. Sand sawn edges with sandpaper.
Assemble and attach all pine components according to Screen diagram (below). Use a drill, 14G smart-bit, impact driver and bugles to predrill and screw components together. Ensure all joints are square with speed square, and all parts are square and flush to front face of the screen frame.
Attach half stirrup anchor to Bottom batten at midpoint between End posts with decking screws.
Apply 2 coats exterior paint to screen frame. Allow to dry after each coat.
With an extra pair of hands, lift frame and insert the End posts and half stirrup anchor into the holes. Adjust frame to allow for a small gap between ground and Bottom batten (around 70mm). Ensure frame is level, square and plumb with level and hammer. Clamp frame into position.
Use bucket, shovel and hose to mix 2 bags of concrete at a time, as per packet instructions. Shovel concrete into all 3 holes until level with ground. Allow to set.
To clad frame, pin an offcut to Top batten to overhang edge of End post by around 10mm. Hang plumb bob over edge of offcut. Start with your straightest Cladding A component. Hold along bottom of frame, aligned and flush with Bottom batten and plumb bob. With a 10G smart-bit, mark and predrill 55mm in from both ends through the middle of Cladding component.
Use the predrilled Cladding A component as a template to mark and drill all Cladding A and B components, then return it to original position and attach with 50mm screws and impact driver. Check level, square and plumb.
To ensure all Cladding remains square and level, put 15mm spacers in between Cladding at both ends. Create a random pattern with Cladding A and B components until you reach the frame top.
Apply 2 coats of decking oil and stain. Allow to dry after each coat.
