How to build a Bench Swing Support Frame
Step 6. Stand the frame upright
Stand the frame upright and balance the beam on the top of the other "A" frame with the beam overhanging 100mm (4"). See fig.14.
Ensure that the beam is at right angles (90°) to the "A" frame and then secure by nailing through the U-shaped nail-on bracket into the beam.
Step 7. Add a brace and make secure
Add the diagonal brace and fix in place with 100mm (4") galvanized nails and nail-on plates. See fig.15.
For further reference on fixing, and nail-on plates go to the 'Fastening detail' page.
