A critical part of the wall assembly in our new house are the window bucks or forms that will be set into the wall LOGIX ICF (insulated concrete forms) before the concrete is poured around it. Because the window bucks have a lot of arches and curves they needed to be built exactly as the windows. I will first build mock windows from laminated plywood which were a half inch oversize. These will be used to shape the bucks and also help reinforce them during the pour. They will be removed to make room for the windows when the concrete is cured. We used our MultiCam CNC router to cut the plywood pieces from which we would build these shapes. We cut sixty four pieces using twenty-five sheets of half inch plywood. The CNC router did the task in less than two hours.

I assembled one test window buck using 2x4's as spacing. Now that the test is complete and successful the rest of the twenty three window forms will follow.
