ok heres a picture of my nami with my custom bumper it took about 15-20 mins drawing it up on CAD and 2.3 min's to mill using a prototrak cnc mill it can be mounted on top of the frame or the bottom the screw holes are counter sunk and slotted for adjustment and the bumper is designed to bend during high impact its easy to bend back. i can pretty much program the mill for any design. i chose that design as a test. the aluminum is feather lite aircraft grade. rear bumper coming soon.
thats a sweet bumper man , i also work in a machine shop on a cnc mill and other machines. i looked at making a bumper like that but i was abit unsure about hitting sumthing really hard and bending the chassi plate because the bumper is so solid . so i went for a plastic one that gives, a fair bit . but good work anyway , it will be cool to see what u make next.
