I’m having an odd problem with my steel shot in the past few weeks.
My steel shot is old carbon steel, from the 80’s, and still working
just fine. After all those years, in the past few weeks, I’m having
the soapy solution all rusty. I use 920 compound from Rio Grande,
simply for the rust inhibiter, and normally, it works just fine. I
can leave the shot in the 920 compound mixed with water for weeks
without any ill-effects. Have been doing that since the 80’s.
All of a sudden, I’m having to change the tumbling solution more
frequently. I don’t know what is going on. I don’t want to get into
using steel shot storage solution, for it means extra steps, extra
rinsing off and more work. I use my steel shot constantly, except
right now, which is my downtime. I’ve used shot cleaner to clean the
shot, but I’m still getting rusty solution. Anything I’m missing? I
don’t want to dump my good ole’ carbon shot while it’s still good,
just to use stainless steel. Call me a frugal New Englander who likes
to keep things going as long as possible. I use clear Plexiglas
tumbling barrels and store the steel in a plastic container when not
in tumbler. I very rarely use the black rubber lined steel barrels,
only for larger work. Like to hear your thoughts.
