If you are asking why laminate, there are a couple of reasons: 1. Laminated struts tend to be a bit stiffer than a solid piece of wood since the grains do not run exactly parallel from one lamina to the next 2. Laminated struts are not as likely to split as the crack stops when it reaches the lamination 3. Laminated struts off the ability to hollow out the middle to save weight or allow a chase to run wiring or hydraulic lines. For example, I laminated the spruce landing gear struts on my Pietenpol. I used a router to hollow out a groove in the two middle laminations that allowed me to run my hydraulic brake lines INSIDE the strut (see picture below) 4. Laminating allows you to make curved parts such as the bows that support the metal around the cockpits, as shown below: Or the curved cutout in the centersection (if you don't use a flop): So my question is, why would you NOT want to make laminations? They are strong, they are very stiff, they are light and they are fun to make. What's not to like?
