First, I have to admit I have never touched a v slot extrusion. I discovered this product in my searching for a low cost guide rail for a linear actuator. My question. Can I rip 2020 to a slightly narrower dimension without compromising strength. I would like to be around 18mm in one dimension. I have a non-ferrous blade for my table saw. The extrusion and wheels will guide the top of a pop-up camper as it is raised by the actuators. Thanks for your help!
