Tumbling help!
Hoping someone might be able to help me out with what I'm doing wrong please!
Have got myself a mini tumbler to save on polishing time, but my pieces are not coming out nice and shiny like I was expecting. I thought maybe it was the pins, so I painstakingly removed them all, but it made no difference.
Hopefully you can see the attachment. I'm using "PMC 960", and pieces made from the same stuff polished up beautifully when my tutor tumbled them! The shot is stainless steel of lots of different shapes, tumbled with barrelbrite.
I'd be grateful for any advice!
