The best man from my wedding is looking for a lugged steel road frame with racy geometry that can have disc brakes. I'm looking for a fun winter project and would like to surprise him. I have two frames in mind, both similar quality: nice but not too nice. I have a 700c disc fork ready to go. I just need to get the disc brake tab, reinforcing strut and cable guide brazed on to the rear.
My question for you all is: Is this a tough job? I have heard from a few interested local frame builders and they either won't work on anything but their own frames or all quote ~$200+. That may be the going rate, but it puts the whole project over budget. Is that reasonable?
Are there any other options? Like going to a welding shop? I know this is a long shot, but felt I had to ask. I don't want to be cheap, just want to understand the cost. How labor intensive is this? I understand it requires more precision than adding, say, a cable guide, but the cost differential seems pretty high ($25 for the cable guide vs $175 for the brake tab).
