Header tube assembly pieces

grabcad

This is a different approach I sometimes take on modelling headers or any tubing for that matter. The parts in this file are made for 1.75" tubes, but you can model it to whatever you prefer. All the pieces are 1" long on the centerline and are modelled after popular bend radii- on centerline, 2" 2.5" 3" 4" and 6". I got the idea from a kit of modelling blocks which snap together like Legos and are produced especially for physical modelling of headers. You can read about that product here: http://www.icengineworks.com/ Using these kits for physical models is a huge help and in some instances helps me make functional 3D models. The plastic blocks have notches every 30 degrees around the edge on both ends for keeping better track of what you are doing before cutting pipe. I have added these points to the model pieces for mating purposes. It's not for everyone, but not everyone does this kind of work either. :) I hope someone finds it useful.
