The ring does show you've hit it hard enough, but if you want to eliminate
the ring, just put rivet tape over the piece and then smack it with
authority! If you examine the dimples with your eyes at close to the same
level, from a couple feet away, you can see if they are deformed. If so, hit
'em again and they will straighten out.

Subject: dimpling question
Sorry to trouble the group with a mundane (and hopefully simple) issue but I
couldn't find anything on the following in the archive:
How do you avoid creating a faint "ring" around a dimple? I get this effect
with the hand squeezer vice grips, c frame tool, and the pneumatic squeezer
as well. There is a faint outline on the dimpled material (0.032 thick)
around the perimeter of the male die, both with 3/32 & 1/8. If I reduce
pressure or don't strike as hard with the c frame I can avoid the outline
but don't seem to get a good dimple. Is this ring just a characteristic of
the dimpling process or is there some way to avoid it?
