Prevent twisting x axis lr3

Happy Easter to you all. excuse my google english. I have a lr3 that can handle 1300mm wide material, I am experiencing some twisting in the middle of the x axis. I have an idea to print new braces that allows me to insert a 50-60mm x 2 mm aluminum tube through the center of the x axis I think this will make the entire x-axis more resistant to twisting, I will screw the pipe through the braces. I would like to hear your opinion before I proceed with this.
