    Billy, do you mean sizing or resizing.. ( sometimes i get hung up on
    semantics and want to reply "use a good ring sizer!) however i
    believe you mean resizing the band,,in which case unless you have a
    sparkie, puk or some other laser or noble gas assisted welder you
    should probably just recommend the purchase of a new Ti ring to fit (
    18-30 bucks wholesale for a plain band -or there about) from the
    first contact with the customer.Alternatively you can cast one,
    using cad/cam, rapid prototypeing with metal powders, or outsource
    the casting from a number of companies. In the general application of
    jewelry repair titanium isn't workable it can be stretched to some
    degree using great care..but with the extra time and procedure it's
    cheaper to replace it, as the metal's structure makes it prone to
    cracking, .If you really just want to try it out, one of those -on
    the inexpensive side- stretching units with multiple rolling dies
    and a horizontal lever that you pull, for stretching stone-in-place
    rings, or milling small lengths of wire, etc. would be a good bet,
    compared to the indo-pak stepped mandrel and planishing hammer type
    unit.. then there's the refinishing steps..If your bench time is in
    the 17-20 dollar an hour range for repair work then its simply not
    cost effective.good luck
