Clamp boards together then use countersink bit to predrill and countersink for screws. Use 30mm screws to join boards.
Apply undercoat to backing board assembly. Allow to dry.
Use pencil and straightedge to draw a 50mm grid on one face of backing boards. Stop grid 150mm before one of short sides to allow for legs to be attached.
Using a drill fitted with 16mm spade bit, drill a hole where each of grid lines intersect. Place backing board assembly on another sheet of MDF prior to drilling to prevent spade bit damaging other face when it breaks through. Take care to keep the drill vertical so holes are straight.
Using mohair paint roller, paint each side of backing board in selected colours. We used Vivid White and True Blue on faces and Orange Vigor on edges. Lightly load roller with paint to avoid getting drips in holes. Apply at least 2 coats, allowing to dry after each coat.
To create leg, first cut 1 leg base with a 45° angle on each end and 2 leg uprights with same angled cut on one end only. Screw leg uprights to leg base so there is a gap between them of 32mm. Make gap centrally located on leg base. Undercoat, allow to dry, then paint half of leg in Orange Vigor and half in Black. Slip leg over bottom of backing board assembly 100mm from the side. Predrill and screw leg to boards. Repeat for other leg.
To quickly and accurately cut shelf pins, set up a stopping block on your bench 245mm from saw blade. Put length of dowel on saw until it hits stopping block, then cut. Repeat to make all pins.
Lightly sand pins to remove saw marks. To paint ends, first dip a sponge in paint, wiping off excess. Dab end of pin on sponge to cover with paint. Reload sponge with paint as required so there’s sufficient paint to achieve an even finish. Apply undercoat first, allow to dry, then use selected colours on ends. We used Black and Orange Vigor.
Place pins in holes. You may have to redrill some holes if paint has dripped down and covered them.
