A company called "Magnaflux" ?used to make equipment for checking
cylinder heads for cracks. They had a powerful magnet that latched
onto the head. A little puff pack then was used to spray powdered iron
in the suspect area. The powder built up around any discontinuity in
the magnetic lines of force, and showed up cracks even when they
weren't visible otherwise. Tom

Is there a way to make dowel pins show in a ground D-2 die part that
has
two
5/32" pins that blend in perfectly? I use the random punch method
now. I've tried holding them up to the light to no avail.





A speaker magnet and grinding dust will do the same job
