I intend on making myself titanium connecting rods. Don't tell me its a bad idea. I'm already set on doing it. BUT, I want input on the exact shape. I'm assuming that the structure has to be a little different to downplay brittleness in titanium. Porsche factory did titanium. Does anyone have one that could take a picture for me?

Pictures from titanium project for vocational school, two years ago. I made about thirty of the rings just for fun. I wear one every day. It's the aircraft grade. And the secret to cutting Ti, I've found, is to use high speed three flute endmills (for milling ops) and high rake lathe tools. Reduce the chip load to .001 and it won't start to get "hard" unless you start to heat it up. So use coolant or plenty of cutting fluid. Nobody should assume that I'm unskilled just because I'm young. Thats REALLY annoying. And Ti is really easy compared to ultem or niobium zirconia, or even tantellum. Hell. 99% pure copper is more of a bitch to machine then Ti. I'll include a pic of what I can do with that. Now this is all assuming that you don't mind getting your arms cut to hell while you're standing at your machine, or that you have an enclosed machining center. Anyway, I got what I wanted. The pictures of the Ti rods. Thanks all. Too bad I was out of town and couldn't defend myself. Most of my closest friends are "old." As in grey hair. Their problem, too, is that they resist change. This works well enough, why do differently? Well. Twysted is right. I want my engine to spin really fast. SCCA doesn't have a rpm restriction. And Ury should think this is a great idea. Imagine the weight I'm shaving off.
