That would be one of those jobs where even if I could (I could, but only really badly) I wouldn't want to. It would need to be back-purged, 'Cos Ti, and so would require one-off back-purging fixtures. And you'd have no idea what tubing was used in the first place and whether it was up to the job. If I was tempted to do the job, I'd make sure I charged more than the price of a replacement frame so I didn't end out of pocket.
I’ve spoken to Vernon Barker who have said they have experience with this and would do it for a palatable price, but they’re up in Derby and I’d rather not have the frame posted twice.
