Introduction: An A shelter of vines or branches or of latticework covered with climbing shrubs or vines. A walk through Garden structure that can support plants and generally complements the landscape. or a A structure with open wood-framed roofs, often latticed and supported by regularly spaced posts or columns, and covered by climbing plants such as vines or roses, shading a walk or passageway. Pergolas are distinguished from “arbors,” which are less extensive in extent and structure.?
This structure might be called either an arbor or a small pergola, but we will call it an arbor. What’s the difference?
Definition of an arbor
A shelter of vines, branches or latticework covered with climbing shrubs or vines. A walk-through garden structure that can support plants and generally complements the landscape.
Definition of a pergola
A structure usually consisting of Being of equal distance from each other at all points. colonnades supporting an open roof of girders and cross rafters. A structure with open wood-framed roofs, often latticed and supported by regularly spaced posts or columns, and covered by climbing plants such as vines or roses, shading a walk or passageway. Pergolas are distinguished from “arbors,” which are less extensive in extent and structure.
This arbor is also designed to be very sturdy, as in a lot of cases an arbor can be a rather flimsy garden structure. This arbor consists of 100×100 (4″x 4″) posts concreted into the ground, 200×100 (4″x 8″) beams checked and bolted to the posts and 100×50 (2″x 4″) rafters fixed to the beams.
About the Timber, lumber. The hard fibrous lignified substance under the bark of trees sizes
The size of the wood referred to in his project is the The finished (dressed) size as opposed to the nominal size of a piece of wood., which is the size of the wood after it has been Surfaced; planed; smooth; even surface; gauged. (smooth, planed, finished).
For example: When a pieces of wood 2″ x 4″ rough size (called the The rough-sawn size of a piece of lumber. Before the lumber is surfaced, planed or dressed. The nominal size is usually greater than the actual dimension. e.g. 100x50 (2 x 4) actually equals 90x45 (1 1/2" x 3 1/2").) is dressed (smooth, planed, finished), it becomes approximately
1 1/2″ x 3 1/2″ in size, which is the actual size.
All measurements throughout this project are given in both Standard/Imperial inches, and Millimeter measurements. (Abbreviation for millimeter which is a metric unit of length equal to one thousandth of a meter. 25.4 mm equals one inch.).
The measurements are given first in inches, followed by millimeters (mm) in brackets ( ).
1 1/2″ x 3 1/2″ means wood that is 1 1/2 (one and a half) inches thick by 3 1/2 (three and a half) inches wide.
And the equivalent in metric…
90mm x 45mm means wood that is 90 millimeters wide by 45 millimeters thick.
The plans and Any of the framing wood. requirements
Below are the plans for the entry arbor with Any of the three linear measurements, length, breadth and depth. in both metric and Standard. Feet and inch measurements. (ft & ins). The plans include front Side view of a building., side elevation, flat plan, and also a 3D view.Lumber requirements.
Use lumber suitable for exterior use.
Posts: 4 pieces 3 1/2″ x 3 1/2″ (90mm x 90mm) @ 9ft (2700mm) long.
Beams: 2 pieces 3 1/2″ x 7 1/2″ (190mm x 90mm) @ 7ft (2100mm) long.
Rafters: 4 pieces 1 1/2″ x 3 1/2″ (90mm x 45mm) @ 7ft (2100mm) long.

1.) The arbor posts
Dig four holes 14″ (350mm) square by 24″ (600mm) deep.
Position the holes as shown in the arbor plan (Page 2). A mixture of sand, gravel, water and cement which hardens to a stone like condition when dry. the posts in place and wait until the concrete cures (usually the next day) before cutting the tops of the posts to the required height.
For a detailed description of how to position the posts, mix and pour the concrete, and cut the top of the posts (including the An L-shaped cutout with one side, that is always at an end or side of a member, unlike a notch that is a U-shaped cutout.), go to here,
and although it is for a different arbour, the method is the same.
2.) Cut and trench the arbor beams
Mark and trench (checkout, rebate) the two beams. The dimensions are shown in the Arbor plan (Page 2).
This can be achieved by setting the blade on a circular saw to the required depth and making repeated saw cuts across the A supporting member. where the trench is to go. Finish by chiseling out the grooves with a sharp chisel. The more saw cuts, the easier the chiseling.
3.) Position the arbor beams
A metal rod that has a head on one end and threads on the other and is used to fasten together lumber. The most common bolts used or referred to in projects within this website are coach/carriage bolts and hex bolts. the beams to the top of the posts with 12mm (1/2″) Covered with a protective coating of zinc. Are round headed bolts with square shoulders that resist rotation when located or driven into place. They can be called coach bolts or carriage bolts depending on which part of the world you live in. The head end of the bolt does not need a washer, but the other end of the bolt (the nut end) usually does./carriage bolts. Use two bolts at each meeting, eight in all. (See picture.)

4.) Cut and trench the arbor rafters
Cut the five rafters to length (see the arbor plan (Page 2) for dimensions) and then clamp them altogether.
Next trench (checkout, rebate) the rafters in the same manner as the beams were trenched in step 2.
5.) Position the arbor rafters
Position the rafters in place on top of the beams. (See the arbor plan (Page 2) for dimensions). The rafters can be fixed in place with 4″ (100mm) (galvanized nails through the top of the rafters into the beams.
That’s it. Enjoy!
