[AT] semi O/T getting things un-stuck

[Gene Dotson]

    Here it is H.L.;    Gene



Removing a broken drill or tap in nonferrus metals (brass -
aluminum,
etc.)

At most any grocery store, buy a box of alum. Select a glass or
ceramic
container (made for
stove top use) or an aluminum pot large enough to place your
part in so
it can be submerged in
water. Remove the part and bring the water up to just below the
boiling
point of the water.
Add alum until no more will disolve, then place your part in the
solution. Keep the solution
at a simmer and you will soon observe a trail of tiny bubbles
coming
from the broken
drill/tap. Keep the solution at a simmer and add water as needed
as long
as the trail of
bubbles continue. When the bubbles stop, remove the part and let
cool
for inspection. You
should discover that the steel drill or tap has turned to a
rusty mud
which is easily removed
from the hole.

Some time back Bear Hood posted the formula for dissolving alum
in water in
a porcelain container and while still hot cooking the aluminum
part to
remove the steel screws etc.

Hi All,

I have an aluminium casting with steel and stainless steel
screws stuck in
it.  From years in the weather.  I have seen posts about
unsticking varius
carb and cylendar parts here.  Any recommendations are welcome.

Thank you,
Dave


On the tractor side of things, I ordered a battery warmer for my
Dynahoe.
When it is zero outside, the battery is too small.  Synthetic
oil and the
block heater help, but I only have a 1000 CCA battery in the
thing.  It is
supposed to have 2 in paralel.
