[TR] Useful info...penetrating oils and their effectiveness

[Doug Mitchell]

Triumphant ones,

I received this from a friend of mine and thought I'd pass
it along to the list.
Someone last week was talking about trying to get bolts
loose. Something
we all have a problem with.

The April/May 2007 edition of
Machinist's Workshop did a test of penetrating
oils where they measured the
force required to loosen rusty test devices. Buy
the issue if you want to see
how they did the test. The results reported were
interesting. The lower the
number of pounds the better. Mighty interesting results
for simple acetone and
tranny fluid!
