Greetings all, I cast a variety of small objects such as buckles,
buttons, and badges in lead free “pewter.” Typically I’ve polished
them using white rouge on a polishing wheel, but thats annoying when
I have many to polish so I have just purchased a vibratory tumbler
My problem is figuring out what polishing media to use, so I’m
hoping someone on this list can help me with advice.
The salesman at the shop were I bought the vibratory tumbler told me
corn cob would work - but this has not proven true. The cob had
little noticable effect - even over night. Then I tried adding in
some “brass polish” they sell for use with corn cob to polish shell
casings. Leaving this over night resulted in a little more
brightness - but still no real shine.
A friend told me he has had success using stainless steel shot, but
he has not tried anything between that and cob. Unfortunately the SS
shot is not cheap so before I go that route I was hoping someone
here might be able to tell me if there are other cheaper
alternatives that might work.
