heres is my design for a 2wd monster truck style tttt. i plan to make the frame using brass but i dont know how to make the U joints to go from the gear that meshes with the motor gear to the worm gear for the back axel. the ones killer made look like exactly what i need but i dont know how to make them. i think that he works on a scale that would be impossible for me to do right. any help would be great. thanks.
