I sourced a Mahogany Astragal from a local mill shop and glued it to the leading edge of my work- ing door. Although French doors typically open inward, requiring
the astragal to be installed on the outer edge of the inactive door, on this project the French doors opened out onto a patio. We thus installed the astragal onto the active door.
GLUING AND CLAMPING You’ll need three 4-ft. clamps for gluing: for the top, middle and lower joints. It’s always smart to dry-fit your parts first and correct any mis- takes before spreading glue on everything—trust me, I've learned this lesson the hard way! Once you’re satisfied with the fit, remove the Dominos, apply glue to all parts, and assemble. Prior to tightening the clamps and walking away, take some time to check for square. I use two methods:
• A framing square
• Diagonal measurements: Measuring for equal diagonals
