SNIP...

The modern way to shrink steel body metal is to use friction heat.  A
metal disk is attached to a disk grinder.  When the rotating disk is
applied to the body it heats the high spots hotter that the rest of the
metal.  Just what you want.  See an amateur video of the technique at:

Look for "Shrinking Disk".  Lots of other helpful metalworking
techniques there also.
