How to build a peaked top arbor

Building instructions continued

Fix the laths to the rafters

Nail the 50mm x 50mm (2″x2″) laths to the rafters.

Begin the first lath 30mm (1 1/4″) down from the tops of the rafters and space all the rest 100mm (4″) from center to center.

Ensure the laths’ overhang is the same at both ends.

Fix the arbor top in place

Now it’s just simply a matter of lifting the arbor top onto the posts.

It is reasonably heavy so it will probably take at least two people to lift it up to the posts and position it correctly.

Once positioned, it can be nailed in place.

Make the frame for the lattice

The lattice frames (one each side of the arbor) comprise the posts, the beams and the lower blocks.

Complete the lattice frames by fixing a 100mm x 100mm (4″x4″) block approximately 1550mm (62″) below each beam.

Fit the Lattice 

The objective is to sandwich the lattice between two pieces of wood (stops) that are fixed to the frame.
The frame is the posts, beam and lower block.
25mm x 25mm (1″x1″) square stops are used in this project.

1. Firstly, fix the stops around the inside of the frame to one side only.
2. Insert the lattice.
3. Fix the stops against the lattice on the other side (see drawing).

Finished!
