I'm new to this forum but not completely new to framebuilding. I started the process of building my own frame about 5 years ago, then due to one thing and another the project went off the boil.
However, I'm now equipped with a shiny new mapp gas torch and have been practising my silver and brass brazing. Which leads me to my question...
How are seat stays attached to the seat lug without affecting the seat lug filler?
As far as I know there are three options:
1. Use brass on the lug and silver for the stays
2. Use silver on both, brass on both, or silver on the lug and brass for the stays and accept that the lug may be affected temporarily
3. Shape the lug so that the stays attach directly to the seat tube underneath (though some heat is likely to flow the filler in the adjacent lug?)
I wasn't able to find any clear info on this forum or the web more widely - any quick hints appreciated!
