[TheForge] Free the Stake!

[Peter Fels And Phoebe Palmer]

I live by the ocean and know rust way too well.
The electrolytic method has enabled me to disassemble parts i 
never thought would come apart.
You can make the positive electrode from a sacrifice piece of 
iron rod and bend it to fit around the joint to be 
cleaned...suspended close by.
Be sure to use a strong, even hot, detergent soak on the joint 
first....pf
