Hey Nigel, that brazing job on the 3-into-1 is amazing.
It seems like the filler has to be filling some really large gaps between the cluster of tubes.
What equipment did you use to make those connections and what kind filler metal was used?
I have a thread about brazing already going at:

If, you have time to donate some of your expertise those of us interested,
some of us might want to copy your work.
Thanks,
Rich
