    I am looking for a chainstay crimper to borrow, I would be willing to pay shipping both ways and provide a deposit if needed.
    Thank You

    I'm still looking to borrow one, like I said I would pay for shipping and a deposit if needed.

    I'm not sure if this'll get you where you need to be, chainmaker. But this is how I buy myself a bit of chain clearance.

    A bolt holds the dropouts at their proper width. Then I spread the mid-portion of my chainstays with a scissors jack.

    I do it slow and gentle. And I flip the jack over, back and forth, in order to keep the stresses as even as possible.

    If there's any 'distortion' of the frame, it's below my ability to detect.

    Thanks, that's how I spread the dropouts...never thought to try it up higher.
