Step 2: Assemble the camera mount
(Mine are 3” apart.)
Mark the holes.
Drill pilot holes for the wood screws.
Screw the angle brackets in place.
Position the camera, with its lens centered between the brackets.
(Leave clearance for the wingnuts – read ahead.)
Mark the position of the camera’s threaded, tripod hole.
Drill a 5/16” hole for the 1 ½” x ¼” bolt.
Test-mount the camera, using one wingnut on the bolt to snug-up the camera.
