Step 1 Screw 4 castors to base of drum in evenly spaced positions.
Step 2 Paint pine in 2 coats of Domino and apply 2 coats of Grey Look Deck to the timber cable drum.Allow to dry between coats.
Step 3 For seat back, cut pine lengths.
Step 4 Hold first length of pine against drum. Using a square resting on drum, check it is perpendicular. Use 75mm screws to fix pine to rims of drum at each point.
Step 5 Butt next length of pine to the first, check they’re flush at the bottom, then screw in place as before. Continue this method to fix other lengths of pine in position.
Step 6 To mark the gentle curve shape of the seat back, cut a length of metal strapping long enough to go around seat back. Temporarily screw strapping to 1 side of the seat back, about 800mm up from ground. Wrap strapping around seat back to form a gentle curve that is about 100mm higher at the middle of the back, then bring it back down to the same height as it as the starting point. Mark this line with a pencil, then remove temporary strapping and set it aside.
Step 7 Using a jigsaw and wearing safety glasses, cut along marked line.
Step 8 Paint cut ends. Let dry.
Step 9 Where the top rim of the drum meets the seat back, screw on metal strapping using button-head screws. Cut another 2 lengths of strapping and fix in place at other rim and near top of seat back.
