Something besides WD-40. Is neither a good penetrent or lube. Liguid
Wrench or what ever great penetrating oil your country has.

Bad...

For two weeks, I dropped every day WD40 (penetrating oil)... I
hammered a lot... Even tried to heat (not too much, but some "hobie"
people said it was useless).... The edge of the corner casting begins
to distort... Corrosion must be here, between the corner casting and
the beam. Nothing moved.

Please help !

I now see two possibilities :

- use other more agressive chemical products : somebody spoked about
"diesel oil" ? Acid (wich one) ? other ?

- cut the aka at the edge of the corner casting, and then "extract"
the inside piece. But how to extract It ?!?

- other solutions ?

Cheers.
