<VV> Removing head studs

[N. Joseph Potts]

Does this process use an air hammer, or just a regular hammer? Is one
hammering IN LINE with the stud, or applying torque (hammering on the SIDES
of the nut, or its FACE)?

        There is a way I've used with frozen nuts, prior to attempting
unscrewing. Some WD-40 (PB blaster not available) then, some hammering, with
a 6 point socket welded to an air hammer shank, more WD-40, more hammering.
If after hammering you see some rust mixed with the WD-40, it is working !
        A tightened nut has metal to metal contact in one side of each
thread and a gap in the other side. This gap is where most of the rust takes
place and it is softer than metal. With the hammering the rust is crushed in
small particles, which tends to run out mixed with the WD-40 or PB blaster,
making the nut less difficult to turn out.
        Don't sure if enough clear but, hope this could be helpful

        PS. If PB laster, WD-40 or querosene is not available... straight
water works too.
