In my previous posting on the house I’m building for St. Williams, my friend David Woodhead noted that he could see some interior bracing in the second photo. (Not only a good ear, but a good eye, David!)
As the above photo shows, I’ve added bracing in the four corners as well as a couple of pieces along the two long sides. I cut pieces from strip wood – the size is not important except that it should be fairly large since it’s structural.
After adding the trim, but before gluing the four walls together to form the structure, I added the large strip wood braces to the inside of the two end walls. I lined this up on the joint between the laser cut wall and the 6″ x 6″ corner trim. Meantime, I measured and drew a vertical line on the inside of the two side walls to locate the mid-wall braces. Their exact location isn’t important but by making sure they will be directly across from each other, they can be used to support interior baffles that will prevent visitors from staring through the house and seeing that it’s an empty shell.
The interior bracing and corner trim also make it easy to glue the side walls into place against the end walls: I simply add glue to the brace and press the side wall against it, tight against the corner trim, with everything set on my glass surface.
Finally, note in the first photo in this post that it’s a good idea to number the adjacent corners of each wall before trimming away the interlocking tabs. Tabs tend to be keyed – they only fit the correct adjacent wall – but once they’re gone it can be easy to mix up the relationship. With numbers, one can match up the edges.
