I loaded 22 lbs. of brass & 25 lbs. of media for the first run.

Ever notice how many and how far pins bounce when you're pouring a scoop of brass/pins from the tumbler into the separator/rinser?  A dedicated, well lit, rinse station is your next step.  |

I did notice how those pins like to jump all over the place.  Rinsing wasn't so bad but I do need a better method for separating the pins.

| I have one of those and it did work well for separating the pins. Most of the pins that escaped did so while transferring the brass /media from one container to the other. |

Don't be afraid of discussing your wet tumbling plans with your friends.
I was telling a guy at work that i was about to order stainless steel media, He looked at me, slapped my in the back of the head and said, "Hey stupee, I can get you all you want, I work part time at a place that uses the stuff all the time. and rotate it. It doesn't go bad, but we just throw the old away. How much you need?" I said maybe ten pounds and he said, "No problem...."

| Question: is it beneficial to ever run the SS pins without brass to "clean" them? I'm thinking after 10 or 15 brass cleaning cycles it might be a good idea just to put some Dawn in the drum and rotate the SS pins by themselves for an hour or more. Would this be productive for any reason? |

Would this be productive for any reason? I personally think it would be a waste of time. i rinse my pins every time i tumble so no more dirt gets stuck on them than on the cases they tumble. everything comes out looking new. there would be no need to wash the pins. but this is america (for now) and if you want to wash them go for it. |

I've noticed that some of the brass I'm washing a 2nd time isn't coming out as bright as the brass came out the first time. I'm putting some of it through a 2nd wash after trimming 5.56 to 300BLK, to scrub off the lanolin and polish the cut edges at the mouth. I'm thinking it's either a difference in the Lemishine (the first wash was months ago, I'm using a newly bought case of Lemishine), or something to do with the amount of Lemishine I'm putting into the mix because I'm washing brass that's already technically clean. If I put in the normal amount for a regular wash - I get some of the brass showing a lot of copper, or distinct coppery spots or areas. When I put in less it's looking dull. I'm scratching my head here over this. I washed about 80K rounds with the 25LBs of pins I have, and one of the other things I'm wondering about is whether the pins have polished the cut ends enough that they're just less aggressive. I need to change a few things and document the changes to compare the results, I guess. Anyway, I don't believe the pins themselves are dirty. It's like the old question of whether my bath towels get dirty or not. The only thing they ever touch is me right after I get out of a shower, and at that point I'm the cleanest thing in the house. |

if you are tumbling lube off you have to use more soap, i have done many experiments and i now double the usual amount of soap if i am tumbling lube off. lemi shine is what makes the brass bright if you uses too much and don't get it rinsed off it can cause the orange tinting. if you are doing really large batches you can run into that problem. -- been there done that too. ETA what i do if i get some turning orange or not bright is put them in a 6 quart container fill with hot water dump in some lemi shine and stir with my hand they turn bright almost instantly then i rinse right away with cold water and they are good to go. |

Silly question....
Let me start and say I am still gathering all the parts to build, but just had a wild thought.... Anyone ever put a very tarnished BCG in with there media? was just curious how well it would clean up, and just lube it when done. Stupid or genius? Thought of this as I am cleaning my CMMG .22 conversion kit

I wouldn't want to be the one expecting the finish on the BCG to be unaffected. Feel free to ignore, post pix of the mayhem. |

So after reading this thread and then eye balling the 'exercise' equipment I've got collecting dust in the basement I came up with this dry tumbler for free. I may go with the PVC setup after a few runs.
Total cost on this project $0(if you saw my reloading table build you know I've got a ton of extra 2X4s laying around) and about an hour of my creativity, and several eye rolls as I explained it to the wife. 
There is about 400 5.56 cases in there and I can run it up fast enough to get sufficient tumbling w/o the setup trying to jump ship. Now to pick up some corn cob from Grainger and some NuFinish from auto-zone. How much corn cob per case count do you guys do? Thanks Harv |

I love it!!! excellent use of exsisting stuff i bet you could do something similar with a wet drum set up.

Yea a PVC setup with hard plastic screw on caps will probably work just as well for a wet setup. Treadmill can carry a 200lb+ person so I could probably turn a friggin Rubbermaid trash can if it was actually round instead of cone ish shaped.

I don't know whether the QC is less important for the pins they sell to us, but I expect the chromium/nickel content is a lot higher in the more non-magnetic pins I've got. Just throwing this out there. And I keep a batch of the mags from HDDs in my sink drain to catch the ones that I can. |

I've almost gathered up everything I need for a tumbler but I'm still trying to figure out the pulleys. For example, when you order a 4" pulley,is that 4" number the out side diameter of the pulley? So if I have an electric motor that runs 1750 RPM, do I order the pulleys at one at 11/2" and one at 4" or do I need a larger one because that number is actually the inside diameter of the pulley? Thankns in advance.

Thankns in advance. Paul when you pick pulleys it is the outside diameter and the shaft diameter. so if you have a 1/2" shaft motor your pulley for it would be 1 1/2 x 1/2 and for the shaft or driven pulley you can use 4", 4.5" or 5" x what ever size shaft you are using i use 1/2" shafts. |
I'm still making adjustments to mine. I was having issues with the drum bouncing because it was slipping on the drive axle. I added a pulley to the idler axle so they now both drive. Seems to have fixed it.
I need to add some rollers to keep the drum off the ends of the frame, finish some welds and it's ready for paint. |

I need to add some rollers to keep the drum off the ends of the frame, finish some welds and it's ready for paint. I had a problem with the idler shaft too. My large drum wasn't too bad but the small one would slip and bounce. I'm using 3/4" shafts. I replaced the rear shaft with 5/8" drill rod. I used 3/4 OD x 5/8 ID flanged bushings in the pillow blocks. Then I used some 3/4 OD x 5/8 ID bushings on the shaft where the drum caps ride and covered those with 3/4" heater hose. Those are kept in place with shaft collars. Now the bushings spin a little on the shaft, the shaft spins a little in the outer bushings and the pillow block bearings spin a little. Pretty much no drag on the idler now, runs smooth and no heat issues with the bushings after 4 hours. |

I need to add some rollers to keep the drum off the ends of the frame, finish some welds and it's ready for paint. I had a problem with the idler shaft too.

Pretty much no drag on the idler now, runs smooth and no heat issues with the bushings after 4 hours. I forgot to add that I also changed out the shafts. I originally started with 1/2" pipe shafts because that's what I had in my shop. They proved to be too light to support my large drum- it weighs 95 lbs when fully loaded. I recently found some 3/4" solid stock on a job site so I remade the shafts. I turned down the ends on my lathe to 1/2" to fit the pillow blocks & pulleys I already had. The increased shaft diameter made it necessary for me to change pulleys to get the drum RPMs back down to where they needed to be. Today I added roller bearings to keep the drum in position and I should finish the wiring tonight. |

ok guys i wanna build one of these kind of a small desktop version. something a few times bigger then a rock tumber but WAY smaller then what most of you are buliding. Im gonna try it dry first maily because of weight and money. this is what i have. the motor is out of a sewing machine and is a 120v 60hz 0.7A. my guess from what i can find is it is just around 1500rpm. im not sure on what to do about pulleys. that site in post one lost me as soon as i clicked on it. not good a math. the two pullys i saved from the sewing machine are .35" and 3.25" and the drum i am gonna try and use is 6" in dimatier. i also have a new unused paint can i can use that is 6.75" in dimatier. my thought was to mount the larger pully right to the end of the drim and the drum sitting on some casters the pulleys and belt have teeth so tention on the belt shouldn't have to be perfect.
what say you?

You should be able to use what you have. If the motor is actually 1500 RPM, the small pulley is attached to the motor and the large pulley is attached to the drum, then your drum RPM would be 1500 * (.35/3.25) = 161 RPM. If you intend to use a drive axle like I did on mine then the diameter of the axle and the drum come into play.

here are a couple of screen shots on how to input the info in the calculator
what you have to remember is rpm 1 is the input rpm diameter 1` is the size of the motor or input pulley or the shaft size in the second calculation rpm 2 is the output rpm of the driven shaft or drum diameter 2 is the diameter of the driven pulley or in the second calculation it is the diameter of the drum You have to remember you need to run the calculations 2 times. you need to solve for the shaft speed first then take that number and input for rpm 1, the shaft size for diameter 1 and drum diameter for diameter 2 and solve for rpm 2 in the first example is to solve for the driven pulley rpm motor rpm -- rpm 1 1500 motor pulley diameter 1 .35 driven pulley diameter 2 3.25 = pulley or shaft rpm so if you had the pulley right on the drum your speed would be 161 rpm and that is too fast in my opinion 
now if you take that info and set up with a shaft using your example here is the results rpm 1 = shaft rpm or the result of the first calculation 161 diameter 1 is the diameter of the shaft you say .5 diameter 2 is the diameter of the drum 6" solve for rpm 2 and you get 13.5 rpm 
if you need more help ask and i will do what i can Originally Posted By Logicgear:

Another great build. looks like that turned out great. Congrats.
now we just need some bling brass pics

OR a smaller pully if im gonna run an axle. casue if i re did the numbers right then if im using a .50 axle then i will have to run the belt right to the axle with no pulley because the calculator said with a drive pulley of .35" i would need a axle pulley .53" on a .50 axle with a 6" drum |
