Stainless pins are sold by weight so you can order just the right amount for your tumbler setup. Stainless steel pins never wear out and will last a lifetime. These are perfect for use in a wet tumbler for polishing brass, steel, aluminum, or titanium. For rifle and pistol brass cleaning the .047" diameter prevents pins stuck side by side in flash holes, yet will pass through all flash holes one at a time.
*Stainless pins are magnetic for easy separation.
*Never wear out.
*Won't damage brass.
*The best wet brass cartridge case tumbling media.
*Quickly shines the dirtiest range brass to like new.
*Use in all brands of wet tumblers i.e. Lortone, Thumler etc.
Tips for Best Results When Cleaning Rifle / Pistol Brass
You will need:
New pins are very dirty. Tumble new pins alone in soap and water for at least an hour before first use.
You will spill pins. Keep a strong magnet handy to make cleanup much easier.
Deprime all cases before tumbling.
Use a wet tumbler which is coated on the inside with non-reactive plastic or rubber. To provide adequate agitation on larger tumblers, use a polygonal drum or one with inner vanes to help turn over the pins. This is not a problem in small diameter round rubber tumblers.
Use more pins than brass by weight with minimum 5:4 ratio or 1.25 lbs of pins per 1 lb of brass. Using a higher ratio pins to brass will clean a bit faster. Pay attention to the total weight capacity of your specific tumbler and don’t exceed the manufacturer recommendation including the added weight of the water and drum otherwise you can quickly wear out or overheat the motor.
Fill your tumbler with pins and brass but be sure to leave space to allow tumbling action. Add clean, hot water until the tumbler is nearly full. Cold water will work just fine but hot water cleans faster. Whether you use hot or cold just be consistent for consistent results. Add approximately ½ tablespoon Dawn liquid dish detergent per 1 lb of brass. The amount of detergent used is not critical but must be enough to ensure good suds remain at the end of the cycle. If you don’t see suds after you open your tumbler either you are not using enough soap or the soap is breaking down from running too long. Optional: To achieve the best possible shine add a very small amount of Lemi Shine dishwasher detergent powder. Start with 1/16th teaspoon per 1 lb of brass. The active ingredient in Lemi Shine is citric acid which dissolves zinc. If you use too much it will leach zinc from the brass leaving it permanently discolored. Increase or decrease the amount of Lemi used cautiously based on your results.
Necessary run times will vary greatly depending on tumbler diameter, RPM, weight of load, water hardness, temperature, amount of soil on the brass, etc. Typically 60-120 minutes is ample but some setups can take much longer for best results. In an 8 in diameter / 60 RPM tumbler we see excellent results in as little as 30 minutes.
Remove, rinse, and separate the brass immediately upon stopping the tumbler. As soon as the agitation stops the dirt will start to stick back on the brass so don’t leave it sitting idle in dirty water. This will also lead to further discoloration from citric acid.
Use a rotary media separator completely submerged. Stainless pins wash out of brass cases quickly and easily with very few turns when submerged. If the separator is not fully submerged water surface tension will stick the pins to the cases and separation will be very difficult. If you are running a large tumbler you will probably want to construct your own separator instead of separating numerous small batches.
Dry the cases. This is not complicated but our method is to shake dry in the separator and then pour them into the center of a large towel laid out flat. Gather the corners of the towel and roll them around to remove as much water as possible. From there we will air dry them several days in plastic trays with an occasional turn. Alternatively you can dry them in a food dehydrator or oven on the lowest heat setting, also giving an occasional shake. Oven drying generally takes only 15-45 minutes. Another alternative drying method is to rinse them in an alcohol bath. They will then air dry in just a few minutes.
