[ARC5] Penetrating Oils

[Robert Eleazer]

A friend sent me a discussion of experiments with various types of penetrating oils.  It seems that after trying various well known and not so well known off-the shelf products they found that the best penetrating oil for freeing frozen screws and things was a 50/50 mix of acetone and any kind of automatic transmission fluid.  

I have a new unused bottle of an unknown type of auto transmission fluid (label is worn off) and I may just mix up a batch of the stuff and see how it does.

And as for my rusty NC-270 tuning cap, I have located a replacement.
