found this (skip to 6:55 for the bicycle tubing TIG brazing):
Looking into the same. Will do some structural tests with it.
Btw normal/gas brazing uses silicon bronze as well, just with added zinc for better flow.
Look at the first pages of the Pron thread on here, this could easily be in there.
Spend some time making a new mitre clamp and flat mount clamp.
And used the flat mount clamp for some brazing (and added some brazing on the Ceeway insert).
Yeah stainless could give some issues, but I've brazed these "ebay-stainless" tubes in the past so didn't bother grabbing some silver.
I used these: https://www.ebay.co.uk/itm/293265076292
I'm not too happy with it too be honest... Maybe try it on the inside of the chainstay next time. Or just fabricate something else.
@Shame dank je!
That with the new violet CK headset would be even better (IMO).
Spend some time today on the internal hydraulic line and di2 wire in the chainstays. For the hydraulic line, I just brazed in a stainless tube.
For the di2 wire, I went with the replaceable inserts Ceeway sells. Not very happy with the result...
