Introduction – Materials and Cutting List
The Porch Swing.
This seat has an adjustable seat-back which angles back to give varying degrees of comfort depending on whether or not you want to sit up straight or lie back a little.
As with other Buildeazy projects, it designed with the home handyman or DIYer in mind. All joins are secured with bolts and/or screws and nails. Because of this, the project only requires the most basic of tools to undertake a professional job.
A bit about the measurements
The measurements throughout this projects are given in both millimeters and inches.
The metric (mm) measurements are given first, followed by the imperial(inch) measurements in brackets.
For example: 50mm (2″)
Note: The metric (mm) sizes given in this project do not convert exactly to their corresponding ft and inch equivalents.
This project gives the dimensions in both metric (millimeters) and imperial (inches).
The abbreviation for millimeters is mm and the abbreviation for inches is “.
The metric (mm) measurements are given first, followed by the imperial (inch) measurements in brackets.
Example: 100mm x 50mm (2″ x 4″).
However, the metric (mm) sizes do not convert exactly to the equivalent imperial (inch) sizes because the measurements are rounded to their respective commonly called sizes.
Example: A piece of 2″ x 4″ wood in North America is the equivalent of a piece of 100mm x 50mm wood in Australasia.
2″ x 4″ is not exactly the same size as 100mm x 50mm.
In fact, if 2″ x 4″ was converted into millimeters exactly it would be 101.6mm x 50.8 mm, and nobody really wants to be calling those sorts of sizes..
Also note that in North America the narrower side of the wood is called first (2 x 4), where as in Australasia the wider side is called first (100 x 50).
When the same piece of wood is made smooth (surfaced, dressed, planed), there is an even bigger discrepancy. 1 1/2″ x 3 1/2″ in North America compared to 90mm x 45mm in Australasia.
A project built using metric measurements will be approximately 1.6% smaller than the same project built using imperial (ft and in) measurements.
In this project the imperial measurements are suited to North America. The metric measurements are more suited to Australasia.
There are two different types of lumber used for this project. 90 x 35 (1-1/2″ x 3-1/2″) treated pine for the frame and 90 x 20 (3/4″ x 3-1/2″) hardwood for the seat slats and back slats. Also a small amount of 145 x 20 (3/4″ x 5-3/4″) treated pine for the arm rest.
If the sizes vary in your area, just make allowances accordingly.
The 45 x 35 (1-1/2″ x 1-3/4″) pieces required are from 90 x 35 (1-1/2″ x 3-3/4″) stock ripped (sawn down lengthwise) in half.
Any other smaller members that are required can also be cut from standard stock.
As well as the lumber in the list below, you will also need…
Two 3600mm (12ft) lengths of galvanized chain
10 galvanized coach (carriage) bolts 10mm (3/8″) x 120mm (5″) long.
A handful of 100mm (4″) nails.
A few 75mm (3″) nails to hold the two end frame members together while drilling and bolting.
92 wood screws approx 35mm (1-1/2″) long for the seat slats, back slats and arm rests.
