    Default Ovalizing tubing

    Yo!

    Looking for some tips on how everyone is ovalizing their tubing.

    I've always put tubes in a vise with soft jaws and squished things into dimension. This works pretty nicely especially with larger diameter tubes but I've found that as the ellipse gets more pronounced the ends of the major axis begin to get pointy and in some cases the top of the minor axis gets flat or even a bit inverted. see attached photo.

    Before I go down the road of making some fancy bending jigs I thought I'd ask if anyone else can share their method on how to make some nice ovalized tubing? How do the big factories like columbus do it for their chainstays?

    Hey Cole the question must be asked — why, or to what end, are you changing the shape of a factory supplied tube? Perhaps order them the way you want them?!

    Hi Richard,

    looking to do these things in house for more control over the process.
    I also would rather use raw stock then rely on suppliers these days.

    That being said I definitely have a habit of going too deep on these projects : )
