Hello all! Please forgive me if this topic has been visited, I was not able to find anything specific in regards to a builder.
I have a 96 Litespeed and I'd really like to have disc brake tabs welded to the rear. The fork is not a problem of course. I'm wondering:
A) who/where I should start (I'm in Dallas)
B) is it a bad idea?
I really love the frame and think the disc brake addition would make it even more of a "forever" bike. I've heard some things about welding titanium that make me a bit nervous, but would do it if the builder/welder was good at it.
Thanks in advance!!

welding a disc mount on is not a significant problem.
however, you will have a problem with rear-end spacing -- most rear disc hubs require at least 135mm. being a mid 90s frame with 130mm, you're out of luck unless you have the rear-triangle re-built with wider spacing.
but for the sake of discussion, lets say you get a disc hub with 130mm spacing. then you may have disc clearance problems with the stays -- on a frame never intended to have discs, a 140mm rotor might fit in there. maybe.
edit: i assumed you had a litespeed roadbike...if you have a litespeed MTB, getting a disc mount added will be no problem. a-la:
i'd suggest finding someone with a little more skill wielding a TIG welder, but you get the idea.

Niall Gengler welded one onto my Litespeed Unicoi. He's in western MA.

Had it done on a '95 Litespeed Obed.
Took several years finding someone with the ti experience but finally Jim Kish moved to the east coast.
Saved the frame from wallhanging.

Not sure where you're located, but TiCycles Fabrication (in Portland, OR) can do this mod (and the rear triangle re-spacing) with no issues.

Thanks guys. It is a mountain bike- the Ocoee. I'll check out your suggestions.

You would have better luck buying a new / used frame. I would bet its a 4-600$ job these days.

The bike has already survived 20 years with rim brakes, and I'm assuming no one has died on it. Why can't a rim brake bike be a "forever" bike?

Good point. I dunno- I'd just like it better with disc. I suppose I could just buy some really nice new V brakes. It looks to be roughly $400.
I wonder if a frame is built differently if the intention is to use disc brakes? I can't imagine anyone more qualified for this than Tom Kellogg or Kent Eriksen.

generally, for retrofits when the brake is located on the seat-stay, some sort of cross-brace is added.
if located on the chain-stay, i've never seen any supplemental bracing added -- apparently chainstays are beefy enough as-is.
