Machining question for you. How do you take a tube, and roll the edge over inside the tube? Like this ![http://www.streetperformance.com/ART/PRODUCTS/100636/th9959324FLT.jpg](http://www.streetperformance.com/ART/PRODUCTS/100636/th9959324FLT.jpg) I can picture it two ways in my head. Spin the tube and use an arm with a roller die to slowly push the material inside. Or A press method. You would have to sleeve the tube most of the way up with the top part of the sleeve having a raised shoulder to the weidth and shape of the roll over you want. Then use a die on the top. I picture a cone shape first. So that the material will start to bend inwards, then once it gets to 90degs or so from the wall of the tubeing, you need another die with the opposite cone shape and a matching female shoulder to the sleeve inside the tube. to press it inside the tubeing. any machinests out there?!?! ---

Vot likes them and wants to learn how to fab stuff up so we got talking. We have a good idea and might roll with it at some point. The edge rolling thing we figured was out of our hands, not to mention the machinery we dont have and the natures of titanium, will further complicate/make it impossible to do.

I like titanium in general. I really like the color of it when its heated and blues. But im refusing to drop 5 bills on that. ---

You need some very rigid machinery, machined dies and forms, and specific rollers to spin titanium. I work with titanium often enough that I have some specific tooling, but even I wouldn’t waste my time spinning it unless it was something super specific. I mostly machined/weld it. And the color effects are anodized, not burned in. Use DC voltage in the 24-120V range and cathode/anodes in solution. Actual voltage determines color. Heaps of info on anodizing titanium online. ---
