I'm going to be repainting my 1970's R531 frame this Winter. I'm thinking of adding some braze on's for water bottles. Two questions:
- where can I find a supplier of the braze-ons... or do I have to make them ?
- are special techniques needed to braze to a frame ? I know that using a low temp is important... but are there other concerns?
You can get braze-ons from framebuilding suppliers. Henry James (www.henryjames.com) in the US, or Ceeway (www.framebuilding.com) in the UK.
Bidon bosses are reasonably easy to apply if you have brazing experience. Use a relatively soft, neutral flame. I use silver solder (56%), as it keeps the temperature down. If these terms are meaningless to you, go to a framebuilder.

Say Suzy, what is your day job? That is the best first frame I have ever seen. And the paint is spectacular, too. Your explanation of the process makes it sound like you just point and shoot, which has never been the case for me, especially with HVLP. Any drips or drabs? -- Jay Beattie.

that is, without doubt, one of the most inspiring things i've seen on r.b.t. in a long time. i've toyed with the idea of building my own frame, especially since i did some braze-on repairs a while back, but i think you've just convinced me to have a go at the real deal. thanks suzy. awesome write-up.

To back up Suzy, braze-ons are nearly always silver soldered even if the main tubes are brass-brazed (as is usually the case: silver solder was only used for fussy tubing like 753, and by real obsessives for 531 to avoid heat distortion).
