Heh, this is an inneresting Q: Can a DIY sucka re-braze carbide to a
blade??

Why not? This guy looks like he's done it once or twice.

Notice how he stripped the teeth off the entire blade instead of
trying to replace just one or two teeth. I bet there is a good
reason for that.

If one joint failed, the rest may be ready.

My nit is that they never showed any additional silver solder being
applied. Is there enough after removing the teeth? I'd be wary of
that.


The way I misunderstand flux is that it floats oxides away from the
joint root and keeps them from re-forming in that important area.

Works for me.


(Flux is magical stuff that can result in gorgeous - looking joints.

Ayup.


It hasn't anything directly to do with controlling the temperature
rise.)

I'm with you.


At 6:33, he should have re-fluxed the joint. See how much more
nicely the next few joints look?

Agreed.


Nit mode: OFF

He is *right* about the 'white' flux. It is just unusable
because it oxidizes very quickly.

It's prolly only unusable for all of us, the amateurs.
