Beam / post braces

The beam/post braces are fixed to the top of the posts and to the underside of the head beam.
Two per post, so a total of sixteen is required.
The beam/post braces are decorative rather than structural, as the posts concreted into the ground are support enough for any sideways movement. For these beam/post braces you will need 16 lengths of 4×4 sawnRough sawn; Not gauged, planed or dressed. treatedPressure treated. Refers to lumber that is treated in such a way that the sealer is forced into the pores of the wood. Refers to lumber pressure sprayed with chemicals to lengthen its life expectancy for outside use or inground applications. pieces of lumberAny of the framing wood. at approximately 16″ long. (It’s up to you whether you replace these beam and post braces with something more fancy.)
At the end of one of the pieces of lumber cut a 45 degree angle (fig 5). Measure back 14″ from the long point of the cut and pencil mark another 45 degree angle inward. SetHow much the teeth are angled out on a circular saw blade. your circular saw blade at 22.5 deg. and cut along that pencil mark.
Repeat this on all 16 pieces of lumber.
FixTo secure with nails or screws. all 16 pieces in place as per fig 5 with 4″ galvanizedCovered with a protective coating of zinc. nails.

It is sometimes wise to drill the nailA short nail with a large flat head used for securing roofing felt, plasterboard, sheet metal to wood etc. holes first with a slightly smaller drill bit to ensure no splitting of the lumber occurs.

Making the hub

The hub is the piece of lumber that goes to the very top of the gazeboA freestanding, roofed, usually open-sided structure which provides a shady resting place. Usually square, hexagonal or octagonal shaped. If on the roof of a house, it is called a belvedere. roof (apex).
The eight roof rafters are fixed to the hub.

Get a length of 4×4 sawn treated lumber 2ft long.
Make a pencil line down the length of the lumber 1 1/4″ in from the edge as per fig 6. Do the same along all four edges.
Set the angle on the circular saw to 45 degrees and rip-cut down the four pencil lines.

You now have made the hub.

Metric version:

Beam/post braces 

The beam/post braces are fixed to the top of the posts and to the underside of the head beam.
Two per post, so a total of sixteen is required.
The beam/post braces are decorative rather than structural, as the posts concreted into the ground are support enough for any sideways movement. If you prefer, you can replace these beam and post braces with something more decorative.
However, for these beam/post braces you will need 16 lengths of 100×100 sawn treated timber at approximately 400mm long.
At the end of one of the pieces of timber cut a 45 degree angle (fig 5). Measure back 350mm from the long point of the cut and pencil mark another 45 degree angle inward. Set your circular saw blade at 22.5 deg. and cut along that pencil mark. Repeat this on all 16 pieces of timber. Fix all 16 pieces in place (fig 5.) with 90mm galvanized jolt head nails.
It is sometimes wise to drill the nail holes first with a slightly smaller drill bit to minimize the chance of the timber splitting.

Making the hub

The hub is the piece of timber that goes to the very top of the gazebo roof (apex).
The eight roof rafters are fixed to the hub.

Get a length of 100×100 sawn treated pine timber 600mm long.
Scribe a pencil line down the length of the timber 30mm in from the edge fig 6. Do the same along all four edges.
Set the angle on the circular saw to 45 degrees and rip-cut down the four pencil scribe lines.

You now have made the hub.
