Does anyone have instructions/ pictures on how to build a ceap alternitive to the Ryedale? and do you think it is possible to build such a contraption to sort for silver?

Here is a link to my home-made sorting device. It worked fine for sorting 1/2 million pennies, but I can't see the point in using it for silver. Sorting for silver is so fast by hand using edge sorting that my device (and probably most homemade devices) could never keep up.
I bet a Ryedale would be faster than edge sorting (it would certainly be easier), but maybe not by a huge margin. But that is moot point because right now the Ryedale only does pennies and nickels.

Also I am currently using a Ryedale assisted sorting method that has sped up my sorting by about 35% and I am considering going to a "quick" 1 pass Ryedale only sort that will be an improvement in speed to my original sorting method by 70% (but a decrease in accuracy). |

| Like horgad said, edge sorting is so fast when clad of the same denomination are mixed in. That white silver streak just jumps out at you. |

Horgad - please expand on what you are talking about....I'm very interested. Ryedale and I have been doing some silver dime and half experimentation. |

I am not sure which part that you want me to expand on, but I am guessing my sorting processes. However, there is nothing groundbreaking there at least not to someone who has sorted as many pennies as you. 
Original Pre-Ryedale Method (about 30-35 minutes per box)
1. I won't go into the gory details of the process but it was about 1/2 hand sorting and 1/2 assisted by a coin discriminator and coin chute. (see picture in previous post)
Old Method (about 20 minutes per box):
1. a single pass through Ryedale with zinc target
2. followed by what I call a "slow pour" of the zincs to find old wheats and Indians by hand (takes like 1 minute)
3. followed by a hand sorting of the coppers
New Method (about 10 minutes per box)
1. All this does is eliminate step 3 from above. I will do step 3 later after the copper penny supply drys up or not at all depending on the market. The whole point being to get my throughput up as high as possible while the coppers are still available. |

Silver1234,
In your original posting in this thread, by "machine" do you mean coin sorter, or do you truly mean a machine in the generic sense that can sort arbitrary metal (not limited to coins) by composition? Just curious...

I mean machine for coins. I have seen some sorting machines to pull out the copper pennies that are made for $30-40. I think I can put one together simular to those, but I just need to find a cheap working coin comparitor. I never plan on hoarding the shear number of copper coins that would make getting a Ryedale worth it. I am trying to hoard silver as well and seeing the low percentages thus far I figured a machine to help sort would make it easier to go through so many coins.
(If yopu are keeping score I have sorted $930 worth of halves and found 3 40% silver, as for pennies I find a wheatie every $2)
On my own I have discovered to use edge sorting (IE just looking at the edge of the coins while in a stack to see if there is one without the copper clad center) So, I am glad to see other people doing the same thing. It is pretty dam fast!
I belive it is feasible to make a silver coin sorter. After some discussion with the company that manufactures the coin comparitor I think it could be set to do so. However, would it be faster than edge sorting for halfs? I am not sure and would it make economic sense to build such a contraption to find 1 in a 1000 silver dimes, quarters, and nickels? I suppose you would have to be doing a very large volume to justify such a machine and expense of building one? |

Our homeschooler group in NY has adopted the project of developing a cheap penny sorter out of cardboard, tape, and posterboard. The current design argument is over whether or not the sliding coefficient of friction increases, decreases or remains constant as the speed increases. Two consulting electrical engineers disagreed so we will ignore them. Gravity fed prototype to be built sometime this weekend. Our group found its first indian head penny yesterday while weight sorting ( at copper roll 140 ). |

You might want to play with magnets...eventhough Zn and Cu are non-magnetic...the megnet does affect the behavior of a moving Zn and Cu coin.
Also, the coef of friction is probably no dependant on velocity. The coef of friction is different when comparing static and in motion...it is lower when in motion. |

Homeschool group progress as of Saturday night - cardboard cut and slotted, ski jump design cut and pieces taped. The road bed is next followed by the coin tilter. Both are poster board we will get tomorrow at the store. The coin tilter is critical in that if the mass of the coin can bear down partially sideways during the entire slide to jump, the friction coefficient will slow down the 3 gram coin faster than the 2.5 gram. The 3 gram will go into the copper pit and the zinc will leap over the copper block wall into the zinc pit.
As usual during the building process, the kids get board, drift away for awhile, go ice skating, surf utube, and stop by periodically to checkup on progress. The parents carry on the project, try to get the kids back on board, and explain what might happen next. I guarentee if this can be adjusted to reliably work, we won't be able to keep them away.
Tourney64 Would the machine have to do the same denomination or would it have to be mixed coins? - Each friction sorter would only seperate two weights of coin. Barriers could utilize boundaries to elimonate too light coins. Too heavy coins above 3.5 grams in theory would get remain in the ski jump ramp path and block other coins but slanting could stop this.
Thanks c140cessna, you got two of them interested in induced electricity and magnetism. I'm going to sort for awhile to relax. |

Enjoy your homeschooling experience. It was the best years that our family had while we homeschooled our son for his last six years of school. Wonderful opportunities around every corner. Glad to read your involvement with coins and this project. |

| If it was worth to machine sort silver, all major coin handling services would have pulled them all out of circulation already. If its not worth it for them, its not worth it for us. |

the friction will also depend on what is on the coin and how slick the coin is.
machine sorting silver would only be practical if you were able to get large quantities of dime or halves...and I do mean large. the cost of the machine would have to be justified by the amount of silver being pulled.
There are many ways to separate zinc from copper. some more accurately than others and some faster than others. You just have to decide the volume you want to do a month and what method will justify the cost. If you are only doing a box a week than a Ryedale is probably overkill.
If you are gonna do $2000.00 a week than more than 1 Ryedale will be required.
Also if you are a hand sorter and can't tell the difference between 1982 zinc and 1982 copper by the "ring" test, then you need a $10 scale.
I started with 1 Ryedale and now have a small fleet, I also have more than 1 coin counter to pre-run the pennies to clean out the junk..ie bent, stuck together pennies along with the dimes, nickels and other non penny coins.
I started small and as my resources increased and my ability to pick up and dump larger and larger amounts of pennies I increased the number of machines to do the work. Most were used and will fetch 90% of what I paid for them if I wanted to sell.
So think and plan ahead...try to get used equipment when you can...this will allow you to by more machine for the least amount of money and also increase your re-sale value.
Edge sorting is fast...I can do a box of halves in about 15 minutes and have picked up a box from one bank, edge searched in a store parking lot, and dumped across the street in less than 30 minutes.
Silver dime machine sorting will involve a precise machine not because of the silver, but because of how thin they are. You don't want to be clearing jams all day due to them trying to stack.
Silver halves are so large that a machine would probably be more costly just because of the size issue. |
