the screw, the best stuff I have found is called "Blaster",[or somthing like
that is in the shop right now] you can get it at auto stores and you shold
have some on hand anyway. Liquid wrench is ok too, WD40 is'nt much good in
my experiance.Leave over night, next day spray some more on and try it, but
dont force it. If still stuck take your propane torch and heat up moderatly
the surrounding area right around the screw, if carefull you can spray some
more pentraiting oil on it again,[turn your torch off while doing this so
you don't blow up] try again. Still stuck? Heat up again this time getting
as hot as you can,[couple of min. of direct flame not on the screw but
around the screw],then let cool some and spray the oil again and try, still
stuck? Heat up hot again then while hot give the screw all you got, as I
have tried everything else possiable if it breaks it breaks.I have a success
ratio of around 95% with most coming loose with the first heat. Now with
your hollow auger you have to wory some about getting the blades so hot they
will lose thier temper so try to keep the flame away from them, as long as
they don't turn blue you are ok.But if they have to come out for it to work
you may have no other option then to get them too hot.I feel if you don't
have to take a rusted screw out don't fool with it,as you do run the risk of
breaking it.Of course if it makes the tool unusable it has to come out,
though some people can't have a tool in thier shop that has a frozen screw
in it even if it affects nothing and must take them out on
principle........Again this is just what I have had good luck doing, Todd
