Didn't think it would work, but tremendous success today in removing a wood screw with a destroyed head. I think my failure in the past has been to use a smaller gauge extractor than required? It beautifully cuts a reverse thread - and out it came, even with a cheap Stanley impact driver. 😁
I'm now a believer.
Thanks for sharing that bit of D.I.Y. extraction. It's always good to see that the extraction bit really works.
Extraction of a different kind.
The white hollow threaded section of a broom handle snapped off at the broom head. I found the remainder difficult to extract with various tools and risked damaging the black internal thread.
Anger intruded and then tried a make or break approach.
I located a bolt slightly bigger than the internal diameter of the white section and heated it up with a MAPP gas torch - and inserted it. Hot internal gasses kept trying to expel it so I eventually kept it in place using a vice.
Let it cool.
Liberal WB 40 applied between the white and black plastic.
Then unscrew the bolt - with the broken piece firmly attached.
I was rather chuffed.
Thanks for looking.
