The curved sling brace was cut out of one piece of timber 5 m long x 500 mm wide x 200 mm thick. It weighed 600 kg and to make it more manageable sections were cut away from the beam with the woodmizer saw mill to reduce the weight. The pieces that were cut away were not wasted as we turned them into knee braces.

Sling Brace Frame #1
Sling brace with the curvature cut on the Robinson Bandsaw. Each beam weighing roughly 250 kgs. |
All joints are transferred up from the template, this is known as 'rafting'. This ensures all five sling braced frames which make up the ribs of the structure are identical.
