I was wondering what the best way to go about getting tie rods made is. i plan on ruinning heims but for the material in between i have some questions. i was told to go wioth a 1" od and thread the ends for the heims. As far as the material goes is 4130 .188 wall tubing the best? i can get 1' od bar stock form work be it aluminium or 316 SS and some other type of SS, hastaloy and a few others i cant think of right now. what do you think. i really like the 316 ss or aluminium idea but will they be as strong at the 4130 tubing? all the machining is no problem so the fact that the tubing is hollow and easier to thread isnt a problem. any opinions?
