Maximum tube node should be selected as shock mounting place it helps in proper distribution of load. Some expensive machines are end mills and abrasive belts.Įven though nodes are the strongest point, too many nodes are not allowed at one point (3-5 tubes). End mills and lathe are most common notcher machine. Harbor freight pipe benderĪ proper fitting and tight notch are extremely important for strong weld joint. ![]() HF “kinker” is infamous for terrible bend on tubing. Do not use pipe bender to bend the tubes because the dies do not fit correctly. You don’t have to worry about heat stress to the tube.īent should be done accurately according to analysis else it will result into negative effect. Some of the tubes are AISI 1018, AISI 1020, AISI 1022, AISI 4130įor fire wall and other roll cage member, bent steel tubing is better than welded lengths of tubing. ![]() Diagonals work best if it is connected to major load points ie spring suspension mount.Īdd additional cross members to the chassis. It is seen bent tubes are better than butt welds (which should be avoided), but still not as good as node formation.Īdd diagonals in roll cage if it is already made and is too flexible. In comparison to straight tubes, bent tubes have more chances to get buckled. In order to avoid from bending which is more worst then compression and tension, tubes should be arranged to form triangles with the major loads applied at the intersection of tubes.
