Garden chair project by Les Kenny
This is a very comfortable garden chair and it doesn’t look too bad either. It would pretty much look good in any garden.
Made out of mostly 140mm x 35mm (1-1/2″ x 5-1/2″) wood, it is a very solid, wide, and deep chair with decent size arm rests. You can laze back in it and do whatever you do when you sit in such a chair.
Note: About the measurements.
- These instructions are given in both metric (mm) and standard (inch) measurements.
- The metric measurements are given first followed by the standard in brackets ().
- In some cases the metric measurements and the inch equivalent are not an exact match. This is for practical reasons.
- Just use one or the other and you will be fine.
- The metric measurements are suitable for Australasia, and the inch measurements are suitable for North America.
- The rest of the world should be able to work out something between the two.
Wood sizes and source
Three different size woods are used in this project.
140mm x 35mm, and 190mm x 35mm, and 90mm x 90mm treated timber.
North America (standard)
1-1/2″x5-1/2″, 1-1/2″x7-1/2″, and 3-1/2″x3-1/2″ treated Lumber.
Actually, there is also a bit of 25mm x 25mm (1″x1″) strip needed as well.
At the time of writing some Lowes stores in North America stocked 1-1/2″ x 5-1/2″ and 1-1/2″ x 7-1/2″ Pressure Treated Lumber in 8ft, 12ft, and 16ft lengths.
Bunnings in Australia stocked 140mm x 35mm and 190mm x 35mm treated timber in various lengths up to 6 meters long.
90mm x 90mm (3-1/2″ x 3-1/2″) should be available in most places.
What the sizes mean
140mm x 35mm means wood that is 35 millimeters thick by 140 millimeters wide.
1-1/2″ x 5-1/2″ means wood that is 1-1/2 inches thick by 5-1/2 inches wide.
Materials you will need
8 meters (27ft) of 140mm x 35mm (1-1/2″ x 5-1/2″) stock, that allows for a little bit of wastage. Always cut the longest pieces first and cut the shorter pieces from the off-cuts
1800mm (6ft) of 190mm x 35mm (1-1/2″ x 7-1/2″) stock.
1200mm (4ft) of 90mm x 90mm (3-1/2″ x 3-1/2″) stock
2400mm (8ft) of 25mm x 25mm (1″ x 1″) stock
Infill of choice for the back of the chair. That can be strips or slats of wood, wrought iron, just about anything to fill an area 530mm (20-1/2″) by 210mm (8-1/4″). Imagination needed.
About 40 wood screws 75mm (3″) long.
Some glue and a smidgen of small nails for the infill (what ever you put in the back opening) and also for the cleats.
90mm x 90mm (3-1/2″ x 3-1/2″)
• 2 @ 564mm (22-1/4″) for the front legs.
190mm x 35mm (1-1/2″ x 7-1/2″)
• 2 @ 900mm (35-1/2″) for the rear legs.
140mm x 35mm (1-1/2″ x 5-1/2″)
• 2 @ 742mm (29-1/4″) for the arms
• 1 @ 672mm (26-1/2″) for the front piece
• 1 @ 600mm (23-1/2″) for the back piece
• 2 @ 606mm (23-7/8) for the side pieces
• 5 @ 478mm (18-7/8″) for the seat pieces
• 1 @ 530mm (20-1/2″) for the lower back rail
• 1 @ 800mm (31-1/2″) for the upper back rail
25mm x 25mm (1″ x 1″)
• 2 @ 600mm (23-1/2″) cleats for ‘under the seat’
• 2 @ 530mm (20-1/2″) cleats for the ‘infill’
Fix every join with glue and screws.
Use two screws at each meeting.
Pre drill the screw holes.
Pre drill the screw holes through the face piece of wood only. That’s the piece that will
display the screw head. Not the piece that is being screwed to.
Use a drill bit the same diameter as the screw.
