Hello,
I am new here, so nice to meet you all!
I'm looking for advice on a magnetic tumbler (Avalon PM200S) that I bought recently. I've tried the tumbler a few times now, and the results have been really disappointing:
10503
This cast silver piece in the picture is an example of what I'm trying to finish. With the tumbler I'm trying to get the silver even in color without any/hardly any residue from pickling. So my only goal is to get the silver clean. To my understanding magnetic tumbler is perfect for metal with hard to reach corners, just like this piece (the narrowest grooves shown in the picture are about 1,1 mm). I've had good results with Otec magnetic tumbler (with 0,5 mm pins), but a $6000 machine is not an option for me right now.
The Avalon tumbler came with "Vilux" compound and steel pins in two sizes, 0,3x5 mm and 0,5x5 mm. I've carefully followed the instructions and used 60 g of steel pins with 500 ml of water and 5 ml of liquid compound. The pins were cleaned prior to use. I've run the tumbler 10 minutes at a time, trying different speeds and both pin sizes separately. But even after 1 hour of tumbling the same piece the result is still uneven. I would've thought that 0,3/0,5 mm pins could reach 1,1 mm grooves just fine!
I've run out of ideas, so if anyone can think of anything that might help, please share your thoughts!
