Here is a pic of the S3 .8mm wall head tube. The lugs are a little loose, but I have some 45% silver that should fill the bill. Who will be the guinea pig in the quest for lightness?
I silver brazed brians rear triangle last night and hope to finish it today, with the exception of all the filing and sanding. I noticed that the polished stainless dropout faces were being marred by the skewer, so I will return them to a sanded finish. I believe that that the softer faces provide a better grip fot the skewer though.
