So I'm wondering if more teams do this? ^^ It's hard to tell from the picture but we welded thick wall aluminum tube (can't remember exact thickness) into the rail and then machined the weld flat and used a boring bar to achieve the diameter we wanted for the bearing. I feel like this would have prevented the damage to the rail in the original picture. What are your thoughts? Why don't other teams do this? Is it unnecessary? Do I just have no idea what I'm talking about? I am very curious.
