The lumber sizes referred to in this project are the nominal sizes. The nominal size of a piece of lumber is the size of the lumber before it is dressed or seasoned and is the size generally referred to when purchasing from the lumber yard. The actual size, or dressed size of the lumber will be less than the nominal size. For example, a piece of 100×50 lumber when dressed may be 90x45actual size. Please make necessary allowances.
All the timber used in this project is 100×50 stock suitable for exterior use.
You will need……
100×50 lumber suitable for exterior use : 18 metres (allowing for wastage)
8 only m12 galvanized coach bolts 110mm long
2 only m12 galvanized coach bolts 150mm long
1 kg 90mm galvanized flathead nails.
Below are the precise sizes and angle cuts of every piece of lumber required to construct the garden seat. Always cut the longer pieces first and then cut the shorter lengths from the off cuts.
All timber illustrated below is 100×50 stock
Garden seat plans
Garden seat assembly instructions
Cut all pieces of timber to lengths and angles as shown in previous page. All angle cuts are 10 degrees off square.
Lay out one of the end frames flat on the ground with the two legs (A) first, followed by the leg brace (B) and the seat support (D) on top of the two legs, and then the back support (E) on top of that. Position as shown in the plan ensuring all ends are flush. (refer fig.1 in the plan)
Hold the frame in place with clamps and drill and bolt all adjoining pieces. (4 only 12mm bolts at 110mm long and 1 only 12mm bolt at 150mm long.) That’s the first end frame complete.
Make up the second end frame in the same way as described in step 1 and 2 but as a mirror image of the first.
Stand up both frames and nail the spreader (C) in place. See fig.1 & 2 in the plan.
Commence nailing the seat slats (F) to the seat frames beginning with the first slat flush with the front edges of the legs and overhanging the sides of the legs by 150mm. see fig.2 in the plan.
Continue nailing the rest of the slats to the seat frames, spreading them out evenly (approx 10mm gap between slats.)
Constantly check that all slats are overhanging the seat frames by the same amount and that the seat frames are square and parallel.
Nail with 90mm galvanized flathead nails.
Finish! eazy with a ‘Z’
