Hello

I've spent the day making two necklaces and soldered on a chain (successful with one not the other sigh tomorrow I have to buy more chain) but can I put them in the tumbler? I have a little one with steel shot. The necklace is 0.9mm thick sterling silver on a bar that is 3x2 (pre hammering size) ... Will I damage the birds if I put them in the tumbler with the chain attached... I cant remove the chain. Photos to follow so you can see...
