Hi all,
Looking for the voice of experience, I'm having a very difficult time making some repairs to a maple syrup arch. It sprung several leaks in one of the float pans due to age and years of I'll just add a bit more solder to fix it type repairs. My plan involves Stainless to Stainless and Stainless to Copper brazing. I started by removing the pan from the side of the arch and striping out all the globs of old solder and then grinding all the parts clean. Problems started on reassembly, I had a good fit up when I started but it went out the window with heat warping. I also had problems with the braze wetting and flowing.
I'm working with approx 16 gage SS (316 I believe) , some copper plumbing fittings & a sheet copper patch. I have several grades of silver braze and black flux to work with. I have better adhesion with the lower percentage silver braze then the higher (I expected otherwise). I did clean everything with stainless brushes and new abrasives. This thing is a clamping nightmare, I was thinking about placing some rivets and filling over them the help with the fitup & warping.
Any tips ?
