@Dave Gidman My silbrazing weapon of choice is a Rothenberger as it is an excellent gas torch. Pharael.
Well I have to admit to only using waterglass a couple times for sealing, but that's the advantage to owning a pretty complete shop as well as being a certified welding instructor. Also a certified Master engine mechanic and in a past life was also a certified master engine machinist. So when I have an issue with something I usually try to just fix it once LOL. However it will seal and I never had a leak issue nor one with cracking either, it looked like clear nail polish after the first heating cycle. I had the waterglass on hand for making paper tubes for rocket engines at the time. Again, the big thing is this is not a project to learn brazing on so an alternative and reversible repair would be the way to go first would be my suggestion.
I understand and I didn’t mean to offend you or anyone. It is a good and valid repair no doubt, especially with your experience but it’s not just about the repair it’s about me learning a new skill. Upping my game as it were. But also knowledge. I’d never heard of sodium silicate as I’ve said but I have now and It would never have crossed my path if I hadn’t asked the original question. in future it might be the way to go and I’m extremely grateful for yours and everyone else’s contribution to this discussion. No doubt others will find this extremely interesting a have i. I’m on my own in this stove endeavour. I don’t know anyone else who’s interested apart from the folks on this brilliant site. So it’s all a learning curve for me. I’ll try brazing till I’m confident then sort the stove as best I can. I’ve got plenty of others to fiddle with but now thanks to this post I have a plan. Regards Dave
