I am just bringing this thread back to the top for new members to see. There is some great information and pictures on making your own tumbler, stopples and cutting your own copper. I found it tucked back 9 pages and the last reply was over a year ago.
Sure am glad you did! I am just getting started tumbling and this forum has the answere to most of my questions, even a few questions I didn't know I needed to ask yet! Thanks to all who have contributed!
looks like some great info in the thread. I plan to tackle this project myself due to $ issues. Now I can hunt for bottles in the woods & 2 speed electric motors at yard sales!
Does any one know about how much copper wire in length equals in pounds? I ask, because everyone refers to how much you need in pounds and I want to know how much length I would need to buy to attain the poundage that is required. I have been using glass beeds for a while and the work pretty good. But, I think I want to move to copper for the sake of time and electrical costs. It takes forever with glass beads and that equates to higher cost per bottle for tumbling. I try to save money, too, by running my machine only at full capacity.
I think I answered my own question. This website gives a conversion from feet to pounds: http://www.arcorelectronics.com/uninsulatedwire/Bare_Copper_Wire.html
I've never measured the wire. I just bought a bunch of it when I could afford it and then started cutting. I probably have around 25 pounds cut now that I use for tumbling, but I still need more. You loose a little bit of copper each bottle that you tumble when you clean out the cannisters for emample so replenishing is required after a time. If you can get it, it's best to get bare wire because stripping coated wire is a pain. One suggestion is when you are digging to save all of the scrap copper and brass that you find. I turn that in at my local scrap yard and get good money for it, right now over $2.00 per pound. I can turn in 20 pounds or so in a 2-3 month period. It helps to pay for the good uncoated copper wire that I then cut.
How much copper in pounds (obviously it depends mostly on the length of the bottle) do you use for a 4" and 6" canisters? I did some calculations (assuming the canister half full with copper shot) and got 14lbs for my 6"x28" canister and 6.5lbs for my 4"x28" canister. What do you think?
