Garden Gate Project - Part 6 - cross bracing

Cross bracing for the lower section of the gate is essentially to aid long time stability. The bracing needs to be less than 45 degrees to each stile otherwise the braces are not actually doing anything. The timbers were milled and cut to length. I chose an angle of 40 degrees and marked out each cut. Then using the tablesaw and mitre gauge the cuts were done.
Mitre gauge is set at 40 degrees

The braces are left long at the moment.

As this exposes a lot of endgrain, engrain glue joints not being very strong, each end will have a #20 biscuit slot cut into them. A corresponding set of biscuit slots will be cut into the top of the bottom rail and the underside of the mid rail. Then the lower rail could have its top face bevelled to aid rain water run-off. A straight portion was left at each position where the bevel mates to the lower rail.

After initial glue up the braces will be trimmed to their final length and glued into place with the biscuits.
