How to use penetrating oil?

Posted by Wayne Boatwright on October 1, 2009, 11:30 pm

I have a 1940s era Hamilton Beach malt mixer and would like to replace the
power cord. In order to do so I need to remove the metal base cover.

The base cover is held in place by screws that are recessed into the rubber
feet and the screws are badly rusted and/or corroded. Only the screw heads
are exposes (and recessed).

I've used penetrating oil years ago on bolts with nuts where the threads were
at least partially accessible, but am unsure how to approach the current
problem.

Ideas?

TIA

Carefully drill off the heads, while applying upward pressure on the
rubber feet with a putty knife shoved between the rubber and the
baseplate. Idea is you want enough of the screw shaft sticking out to
grab with visegrips, and rotate out of the hole. Take the cut screw to a
hardware store, and find something 'close enough' in stainless, to
replace it.

Or, cut off the rubber feet and then maybe you can get some pliers on
the screw heads. Rubber feet can be bought at most quality hardware
stores.

Get the mixer in a stable position either on its side or upside down
and insert a screwdriver into the screw and push HARD against the
screw. At the same time apply a rotating force as if to loosen it but
not enough to have the screwdrive slip. Whack the handle of the
screwdriver with a hammer. Sometimes the shock of the hammer blow
will break the screw free.

You could also try an impact driver which you can get at almost
anyplace that sells tools. You will just need an adapter to get down
to the the right size bit.

I doubt any type of oil will work because it needs to get to the
threads an it won't be able to get around the rubber. You might be
able to just pry the feet off around the screw head then grab the
screw with vise-grips. When you put it back together a washer will
most likely hold the feet on if they get damaged.

If the cord is not damaged right near the base you can safely patch a
new cord on or just buy a replacement end.

Good luck!

I would try all those destructive suggestions later. Most of which should
work.

First I would secure the mixer upside down and fill the little recess in
the feet with the oil.

Protect the base and the surrounding area with lots of paper towels. The
oil needs time to seep and work the magic.

24 hours later try removal and repeat the process if needed.

Since this is an older unit, probably designed as a commercial model, you
may find brass or SS bore and screws which are just stuck and corroded from
age and use.
