A while ago I invested (cheap route) in a HF dual drum rock tumbler and got the SS pins needed along with lemishine and dawn. At first both drums cleaned equally well with equal bling. I stopped for a bit because I ran out of brass to clean. Well the drums and pins sit for a few months and I recently purchased some 9mm and other brass. I start to get everything done and now with the wet tumbling I notice that one drum is leaving the brass a darker yellow than the normal bright yellow of the bling we all like.
It also looks like the brass was clean but almost like a "film" of some sort is keeping some of the dirt still on the brass. So I ran a batch through the other drum and it removed the rest of the dirt/film? It is only the one drum and to the best of my knowledge I haven't run any steel in either nor have I mixed the pins from one drum with the pins from the other drum. I had even added a little bit more lemishine and dawn and the results are still the same. Any thoughts as to why this is going on? Dirty pins? contaminated drum? I have no clue at the moment. |

Is the inside of drum a polymer? Was it left in storage room or garage all summer? Might be breaking down from heat
I would recommend more dawn, not anymore lemishine. Try a few more small batches. Likely the drum will cleanse itself of an outer bad layer. I only say this from experience with my FA drum. ;) But my film was more black in color. |

Not poly just the hard rubber that they use. The drums were not stored in a hot location either not just sitting in my living room. Not sure if this will eventually wash out or not.

Too much lemi-shine will leave a dull color.
I've let my pins sit for weeks and never had this problem. Same tumbler. My pins are from stainlesstumblingmedia.com. I'd run just the pins and dawn to clean things up and try again with less lemi-shine. |

View Quote rubber, poly, whatever . All break down with heat. But as other poster said, too much lemi not great. If you are cleaning post lube/size, I let my brass soak in dawn/water first to get bulk of lube off first (unless I am rushed). |

when is the last time you cleaned your pins? Dont laugh...they get dirty too. Run a load with no brass and some dawn, bet the water will come out black and then you will be back to nice clean brass.

Here's what I've been doing lately.
Clean your pins as suggested above. I have a FA wet tumbler. Run 1 hour in Dawn and pins, dump the water and replace with fresh Add car wash and wax soap and 1/4 teaspoon lemi-shine Run additional 1-2 hours |

Nope none of the cases had any lube on them, only doing pistol at the moment. Will try cleaning the pins and see what happens. will update when I can about this. have to work 12 hr shifts the next 2 days.

Not had ANY issues unless too much Lemishine was involved. You will get far better results using less Lemishine than more. |

How much Lemishine are you using?
The SSM folks recommend 1/4 tsp, but that seems to be too much. |
|
[#13]
I use one 45 caliber casing, of course it depends on how big your tumbling drum is. My drum is about14" long and 6" in diameter. IMHO you really have to use a lot of Lemishine for the results to be negative. Also the theory of the pins getting dirty IMHO does not make sense. Why if you use Dawn or any other detergent to tumble would your brass come clean but your pins would not? I have used the same pins for over a year and have never cleaned them.

Just got back from work, I use 1/2 of a 9mm case of lemishine per drum per cleaning cycle.

Always best to start with the smallest amount that gets them to the "tint" of shiney that you want. |

I use 1/2 tsp per gallon of water and it shines them up very bright!

I see this occasionally, it's most noticeable with nickle plated cases. It may be due to insufficient Dawn. I think the pins do get dirty as well. Put your hand in them and you'll see what I mean.

Been busy here so sorry about not getting back to everyone about this.
Recently some have mentioned that the pins are dirty, and others have suggested it is because of the water and how much lemishine. Either way I put a healthy squirt of Dawn in there and ran it without any brass in it. Low and behold the water came out dirty. Not totally filthy like I just did a batch of brass but still dirty enough for me to go ewwww. Now here is where I started to do some thinking, The brass I bought was range pickups from someone that has access to basically a private range. I was thinking what would make the pins dirty? I have tumbled a good amount of brass and never really had a problem like this. Then I got to thinking what if it could be because someone had shot reloads? normal jacketed reloads should offer no problems at all since it is very similar to factory ammunition. The it occurred to me, What it the person was shooting lead cast reloads? The lube for the projectiles... It makes sense if you think about it. the lube is basically petroleum based and I would figure that there would be (SOME) residue left inside the case. Figure after several batches the pins could get dirty as a result. The dawn would remove it from the case for the most part but not entirely but also coat the pins. What do you guys think? |
|
[#22]
I fire cast reloads in 357, 7.62x39, 300 blk, 9mm, and 45 ACP and then wet tumble the cases.
I never had that problem. Scrub out the inside of your drum, or run another pins/dawn/Lemishine batch. See how clean water is afterward.

If your worried about the drums on the HF unit, just replace with 4" PVC pipe. Use a plug on one end, and a pressure test plug on the other. My buddy had to do this, as his drums got flakey after awhile.

I use 15cc of lemishine with 7lbs of water, just shy of 1 gallon.

We reloaders measure Lemishine by using pistol cases. For me with a Thublers tumbler a 45 ACP case. The closest I've come to measuring is using my wife's measuring spoons. But I also use the turkey basin/pan for lubing brass. |

Someone mentioned using PVC pipe instead of the rubber tumbler drums. Offhand I tend to think that the rubber drums for some reason get a little goofy and are leaving something on the cases. Currently I am in the process of making my own PVC tumbling drums. As I am sure all of you know is that PVC pipe is smooth on the inside and that you need to add something (usually 1/2 in pipe) cut lengthwise and bolted to the main piece to help in the tumbling motion.
One person said that someone they know used some of the plastic from hangars and I found out that the 2 plastics will not bond together properly and come loose. So I thought of another way. I had bought a 2 ft length of pipe and cut it so I can make 2 drums that would fit the whole length of the HF rock tumbler. I had a leftover piece from making the 2 drums. I cut 6 pieces lengthwise from the leftover pipe and am cementing them in at this time. The thing that dawned on me is that since I am using remnants of the same pipe I can cement them in and the bond should be better but also the curvature from the outside will match the inside of the pipe and lay nice and flat. Once I get them all in I will snap a pic or 2 with my i potato. and let you know how sturdy they are. |

I think I know why one of your drums is cleaning better than the other. I too have a HF tumbler and noticed early on that the plastic tab that keeps the drums from running into the ends of the metal frame didn't do its job well. If there isn't something to keep your drum from hitting the side of the metal frame then you will have circular scratch marks on the top of your aluminum lids. I simply put a small piece of plywood against the wall and shoved the HF tumbler up against it. That way the plastic nut will hit it and keep the drum from scraping on the metal frame. If you need pics I can provide some.
Long story short... I bet one of your drums is not turning as much as the other one. That's why one of the drums brass isn't as clean. |

If that PVC cement does not hold (it should), use JB Weld it will never come loose. A while ago someone posted that using JB Weld will turn your brass black because JB Weld contains metal. This is FALSE, there is no metal in JB Weld.

V View Quote i made the mistake of using JB weld in a tumbler. it does turn black. i also placed a cured bunch of JB weld from the mixing tray next to a neodymium magnet, and they did attract. also the stainless pins can gain magnetism if you use a magnet to transfer. any metal particles that adhere to magnetized pins will be in the drum when washed. |

I stand corrected here is the MSDS sheet. It clearly states that it contains a small amount of iron. I cannot see how it can be listed as an insulator however. I mixed up a small batch of it and after it cured it was attracted to a magnet. I did check it with a digital Fluke and it registered 0 ohms so it is non conductive.
I still maintain that my two drums are working fine with no black or dark brass coming out of them. V |
