Drilled hinge and bolt holes and trimmed width on two flap hinges. All hinges so far align perfectly. To match drilling 3/16 attach holes at square 'T' was drawn on workbench. 1/4" hole was drilled first, burr removed then the two mounts were aligned over the 'T' (the 1/4" hole and back-side of the mount square) and clamped together. One side of the hinge was prepunched, this makes sure both sides geometry is the same.
