scribble Posted June 28, 2007 Share Posted June 28, 2007 (edited) I just received my new lyman 1200 auto-flo tumbler new, it came with 3 small bags of green media. I decided to try there media out on some dirty 45 cases. I have had the cases sitting on the shelf in an akro bin for 2 weeks. I started the tumbler with 250 cases in it and set the timer for 2 hours. I came back to find the cases were dirtier than when I started and the bowl looked like the media has melted to and stained the inside. I started with a Lyman orange bowl inside and ended up with this: O and I tried cleaning it but nothing work, I even tried a heavy scotch bright pad but it wouldn't touch it.

RePete Posted June 28, 2007 Share Posted June 28, 2007 The staining is normal. My 1200 is 25 yaers old. The treated corncob is the best - in my book. Link to comment Share on other sites More sharing options...
Joe4d Posted June 28, 2007 Share Posted June 28, 2007 mine too, cept it's red from thier red media, and by the way in case you havent figured it out, Dont use Lyman media, especially the red. It disolves into a dust and it will destroy the motor. Just buy the bulk, about $15 for 25lbs untreated corncob and get a bottle of midway, flitz, or dillon media solvent.

scribble Posted June 28, 2007 Author Share Posted June 28, 2007 I just got off the phone with Lyman and they told me that the green stuff is the polish compound in there media that is sticking to the case. They also said I didn't tumble them long enough, they said minimum to tumble is 4 hours. I guess I will try and tumble some more tonight and go from there.

valkabit Posted June 28, 2007 Share Posted June 28, 2007 I have some of Lyman's walnut media with a reddish rough on it, the walnut is sort of a coarse grind. It's really done a great job for me, I have polished cases that had been reloaded maybe 6-8 times without a cleaning, and the cases really gleam now. There was a reddish dust on everything (cases and bowl) so I just ran the cases thru some old corncob media with no polish in it, and everything came out shining (15-20 minutes). I'm assuming the red dust was just from the rouge on the walnut, and will not hurt anything. Link to comment Share on other sites More sharing options...
scribble Posted June 28, 2007 Author Share Posted June 28, 2007 I am familiar with dust left behind but this is like a melted on rough coating. I washed it and even scrubbed with a scotchbright pad and it didin't even fase it. I heard back from LYman by e-mail that they think a large clump of compound and media formed a ball and adhered itself to the bowl internals. They are sending me a new bowl and more media.

valkabit Posted June 29, 2007 Share Posted June 29, 2007 Yea, your picture shows something I've never seen before. It's great that they are sending you a new bowl, not so sure if it's great to get more of that media. Link to comment Share on other sites More sharing options...
scribble Posted June 29, 2007 Author Share Posted June 29, 2007 Ya I agree on the media part. I tumbled some corn media that I normally use in there with teh casess from the original batch and some nu-finish and a good portion of the green sludge was removed but there is still alot of etching in it from the first tumble. The brass came out nice and shinny this time, but I am not going to turn down another bowl to replace this one. Link to comment Share on other sites More sharing options...
DaG Posted July 4, 2007 Share Posted July 4, 2007 A bag of rice is the best media I have found so far. DaG Link to comment Share on other sites More sharing options...
Hairtrigger Posted July 4, 2007 Share Posted July 4, 2007 Mineral Spirits will take that stuff off. I get the same when I add too much polish Link to comment Share on other sites More sharing options...
scribble Posted July 4, 2007 Author Share Posted July 4, 2007 I noticed after tumbling several loads in it with ground walnut the residue is mostly removed. Link to comment Share on other sites More sharing options...
