I have all the parts to make a brass tumbler to use Stainless Steel media. I have some nagging questions if any care to opine:
1. Are all pins in a given size range equal?
In researching online for the most economical source, I find a difference in the quality of the pin ends. Whether due to worn shear dies, or lack of a finish de-burring operation, I'm wondering if those pins with a visible end burr will adversely affect, enhance or have no effect on my brass polishing effort. (They are a lower cost.)
2. Container size verses pin and brass ratio?
My home brew version utilizes a one gallon heavy wall, plastic chemical jar. (roughly 5 1/2" dia. X 10" tall) My batch expectations are for 60 to 80 45-70 brass but also do regular batches of 45 colt among others, I can adjust the quantity down if too many for my jar.
Given the lightest brass load for that jar size which in turn (I assume) means the largest media volume:
How many pounds of pins to buy is hard to visualize. 4 to 5 pounds?? Having not seen this media, pictorially it doesn't look like much volume in 1 pound. I'm guessing less than cup?
My dad did some rock polishing when I was a very young and one thing I remember him saying was the rocks must tumble in the media, but not fall, or they could chip or crack against themselves. To accomplish this, he would ensure the rocks were fairly equal in size and adjust the volume of them and or the polishing media.
Obviously my brass is not going to chip or crack but the tumbling verses falling still applies to maximize the media contact and polishing action.
Thanks for your time and advice.
