Center Strap -
There is no buckle assembly. The 1 inch wide tubular
webbings are grommeted to the side gunwales. A smoothed 1 inch by 3 inch
1/8th thick aluminum shim is 'swallowed' by the tubular (not flat) webbing.
The shim is secured by stitching. A 2 & 1/2 inch to 3 inch piece of 1/8
inch diameter climbing cord (cotton cord at any hardware store is also
acceptable) is looped through the webbing and stitched into place. During
assembly this loop is secured by the center brace support (version 4.1).
Measure carefully to make these loops taught and benefit from additional
tension.
Center Brace - The center brace bracket is a little different. The photo is bad, but I
wanted to show there is no nut. I tapped the aluminum and wood and drove a
10/32 flathead screw through. Then the aluminum and wood was clamped and
glued. The thread was permanantly locked into the bracket also. That is
how it's a little different...
Mid Brace Squares - My brace squares float over the screws on the
brace side of the braces. This modification eliminates riveting and
trimming the angle squaring braces. One drawback: the top midbrace squares
need to be notched 1/4" to allow the stringer notch to pass through. The
floating design works on the end braces too.
End Gunwale - Four securing straps are used instead of two. The two
additional straps provide additional security and are used to eliminate the
aluminum to wood snaps on the mid braces. The side gunwales use an end tab
of 1 & 1/2 inches providing great stability, but do not allow the use of
midbrace to end gunwale snaps (the tab gets in the way.). Four straps help
alleviate this shortfall.
