How to build a Bench Swing Support Frame
Step 2. Lay the legs on stools
Lay a pair of legs out in "A" frame position on three stools or supports. See fig.10.
Position the horizontal brace on top of the two legs.
The bottom of the horizontal brace should be 600mm (2ft) down from the top of the "A" frame.
Refer to the plans for more positioning dimensions.
Step 3. Fix the "A" frame
When the "A" frame members (two legs and one horizontal brace) are correctly positioned, they can then be secured together.
Use a 100x100 (4x4) nail-on plate where the two legs join and fix a U-shaped nail-on plate to the top of the "A" frame. See fig.11.
Also see 'making a U-shaped nail-on plate' in the 'Fastening detail' page.
Use galvanized bolts to fix the horizontal brace to the legs, one at each meeting.
Hold the horizontal brace to the legs with a couple of clamps prior to drilling the bolt holes.
