One way my dad use to solder blades is prepare the ends of the blades
with a tapered lap joint. Apply flux and a piece of flat silver
solder, then using a set of soldering pliers that have been heated to
red hot with an acetalen (sorry for spelling) torch, then gripping the
band with the pliers.

His pliers where about 18" long, (end to end). The heating end was 1/2"
square iron stock.

Should only take 30 secs or so to solder the joint.

As for the black gunk, it sounds like you are getting contamination from
your torch.

Hope this helps. If needed, I could probably get a pic of the pliers.
Just let me know.

Just remove the dashes from my address

Hello
Not having great luck. I have some rolls of bandsaw blade stock. Any
hints
or tips greatly appreciated. Can flux go bad or get contaminated? It
seems
the solder melts but doesn't have that nice flow , but instead just
lumps up
into a nice cold solder joint. I cleaned the joints well , but when I
apply
the heat til it gets red hot I get this black gunk gathering at the
ends of
the blades. Is there a different flux for non ferrous & ferrous
metals? I've
silver soldered before with great success.Thanks.
