Excellent sequence of pictures, the page has been download to my Engineering Tips folder.
Many thanks.

one_rod, would silver soldering work or has it got to be brazed?

Rob,

I used to silver solder my own, and it works just fine.

Not sure...... It was a very long time ago...... Did I work on a bandsaw with a built in electric butt weld device, to do that?  :scratch:

Yep. Those electric resistance welders are a great piece of kit. Do the whole job in about two minutes. Some even have a little grinder to clean up the weld afterwards.

Some big industrial saws had them built in, but portable units can be had. Trouble is that even tatty, second units tend to be eye-wateringly expensive.

I can't see any reason why silver solder shouldn't work, although I have never tried it myself.
If you have a worn out blade to play with then the easiest thing would be to cut it, solder it back up and run it on the saw for a while.
As you probably know, even if the joint fails nothing bad will happen. the blade simply loses contact with the drive wheel and stops.
Got to be worth a punt, if you have some silver solder laying around.
If you do try it, let us know how you get on.

EDIT:

Thanks John.
So now we know.

A major advantage of having the built in butt welder is the ability to break the blade, place it inside a work piece, weld it back and carry on with the project. Once finished , break the blade again to free up the work piece. This was handy for cutting openings in SS plate.
