Is anyone else excited about \"How To Build a 4-Link\" in 4W&OR? Maybe it's just me, but I really enjoyed last month's article on the basics of multi-link design, and this month's issue they really got into some in-depth discussion. I know there will be SOME folks here for which this info is too "basic", but I'll bet the majority of folks will really learn something and maybe get excited enough to consider tackling a project like that??? On a related note: It's cute that they suggest drawing all this stuff out on graph paper, but I think after about two iterations of designs that didn't work I'd be fed up with THAT system. Anyone know of a very "simplified" CAD-type program that could help with the early design work? I dunno...plug in the CG, and a few constraints....link positions and angles, and maybe have it calculate the IC, Roll Centers and maybe even show the predicted wheel travel arcs???? Am I asking for too much here??? /forums/images/graemlins/grin.gif I could probably build an Excel spreadsheet to do most of it, but it would probably take me longer than the graph-paper way!
