I usually cut the head and threaded portion off leaving a "slug." THEN I use the 20T press and a cold chisel/drift cut off short and slightly smaller in diameter than the slug. Press with MINIMAL heat applied to the axle.

Somewhere in the Ford literature Ford says to NOT heat the axle prior to straightening - and for steel this grain size transition point typically happens around 400F. Most welding of steel is best done between this temperature and the transition temperature of about 770F. So I stay below 400 using welder's temp crayons.

The slug is pressed out doing minimal compression - the tool doesn't "mushroom" itself, and you can re-do the attempt at increasing levels of press - keeping control of the process.

Thermal cycling and Oil of Wintergreen is your friend. Lots of Oil of Wintergreen in PB Blaster.

Heh. Saying this reminds me of the book "The Sand Pebbles" and the movie with Steve McQueen.
