How to make a garden swing seat support frame

Instructions

Step 1. Cut all the members

Cut all the members to length and with the angle cuts as described in the Individual Pieces (Page one).

All the lumberAny of the framing wood. used is 100×100 (4×4) stock and all the angle cuts are 26.6 degrees off squareA line across the face of a piece of wood (at right angles to the length) is a square line. A line deviating from the square line is off square. Off-square refers to how many degrees the off square line is in relation to the square line. For example, a line at a 5 degrees angle to the square line, is 5 degrees off square. except for the two diagonal braces which are cut at 45 degrees both ends.

There are directions below on how to make the angles if you do not have any type of angle marking tool.

fig.7 shows the cut lines at the top of the legs. fig. 9 below shows how to mark the cut lines at the top of the legs and fig.8 shows how to mark the cut lines at the bottom of the legs.

How to mark the 26,6° cut line at the bottom of the legs

(1) Square a line from x to y (fig.8) across the leg.

(2) Mark point z along the leg. The distance from z to x should be exactly half of the distance from x to y.
For example: if the distance from x to y is 100mm (4″), then the distance from z to x should be 50mm (2″).

(3) Draw a line from z to y. This is the cut line and is 26.6° off square.

How to mark the 26.6° cut lines at the top of the legs

(1) Square a line from x to y (fig.8) across the leg.

(2) Mark point z along the leg. The distance from z to x should be exactly half of the distance as that from x to y.
For example: if the distance from x to y is 100mm (4″), then the distance from z to x should be 50mm (2″).

(3) Draw a line from z to y.

(4) Mark point u 50mm (2″) from z along line zy. See fig.9.

(5) Square a line from u to v (fig.9) across the leg.

(6) Mark point w. The distance from w to v should be exactly twice the distance as that from u to v.

(7) Draw a line from w to u. This line should be at right angles to line zy.
