how to separate carbide from base metal

[devo]

I was wondering if any of you metal guru's could give some opinions on how to remove the carbide cutting edge from the base head of shaper and moulder heads like these:

I've been looking into this, and I believe they a silver brazed together ( I may be misunderstanding the process ). Using a torch works good on sawblades, but that's a lot of fuel to heat up a big chunk of metal hot enough to remove the carbide.

silver brazed is about the strongest isn't it ? got a big kiln ? i saw somebody giving away a whole kiln works on cl the other day, it was removed before i clicked on it

vise hammer and chissel works for me most of the time although make sure you wear gloves and safety glasses i learnt the hard way

Heat it up in a fire till its a light red colour & pick it out & bash it against something solid.

Thanks. I was thinking of heating them up in a hot fire. If nothing else it would preheat them and save some acetylene.
