Dimple the chainstays on a Ti Serotta?

Framebuilders Thinking about a custom frame? Lugged vs Fillet Brazed. Different Frame materials? Newvex or Pacenti Lugs? why get a custom Road, Mountain, or Track Frame? Got a question about framebuilding? Lets discuss framebuilding at it's finest.

Dimple the chainstays on a Ti Serotta?

Hello All:
I recently picked up a '96 model Serotta Ti. Tire clearance is surprisingly tight: 23s just barely fit and 25s rub. Is it possible to dimple a Ti frame once its built? I really like 25s on the chip-n-seal around here and have a multiyear stock of them.
I've read what I could find through google and it seems that adding a crimp or a dimple to steel chainstays for tire or chainring clearance was pretty standard in years past (when tubes could handle it) but I don't see much discussion about titanium. For old style steel it seemed to just involve a clamp with a support for the side of the tube you don't want to dimple and a die to give you the dimple shape you want.
If it is doable, can you give me some idea what I should expect to pay? I imagine it might need to be re-aligned afterward as well.
Thanks in advance,
Jim

It is in steel .. but that was usually done by the tube mill to the tube set then put in the box..

in Titanium contact a TI frame builder .. Serotta an obvious choice ..

As a metalworking proceedure, seems a cut away and a patch welded to be flat

where it was round can be, theoretically, done .. to a already welded frame

if you worry most about cost , live with it as it is. or sell it and get one featured as you now realize you need.
