I recently broke a tap in a newly made aluminum power steering bracket for my 1929 Ford Hot Rod. Several methods of removing the tap failed. Upon a bit of research I discovered that the tap, drill bit, or even a steel screw/bolt can be removed effortlessly by boiling the aluminum part in a water and alum solution without destroying the aluminum part. This was so simple and worked very well.
