Riding Mower Coin Tumbler

[LawrencetheMDer]

Each year I find 1,000-2,000 coins while metal detecting mostly beaches and I've been searching for a large but inexpensive way to clean my found coins via tumbler. No luck. Coin tumblers run $150 or more - a large chunk of my change. So I searched for a cheap way to build a large coin tumbler; one that could handle at least a 1,000 coins. My solution: The Riding Mower Coin Tumbler.




Here is a picture of my Riding Mower Coin Tumbler - I have attached, by 2 - 30" pull-cords, a 2 gallon plastic container to a back wheel of my Craftsman riding lawn mower. I filled the container with about 900 coins and off I went...nothing happened. The coins simply slid along the smooth bottom of the container as the wheel turned and I couldn't go fast enough to enable the coins to tumble. To solve the problem, I placed a coil of 1/2 copper tubing tightly inside the container so that as the container turned the coins would hit the copper tubing and start to tumble, it worked. After 20 minutes of cutting the yard, I checked the coins and found them to be much cleaner and also found a large amount of fine powder in the container - coin crud residue.



Thirty minutes is about enough time to tumble about 1,000 coins, although they still need to be washed and dried. Feel free to improvise on my invention. If you decide to replicate my findings, I should warn you - use a secure container; otherwise, you might be using your metal detector to find coins that you're already found. Also, DO NOT replicate this type of tumbler with your car or truck.

My double drum tumbler was right at $52 from Harbor Freight, but you've got one heck of an idea there

LOL!

I'd say this is Red Green approved, but you didn't use duct tape.

How much does a riding mower cost? [emoji4]

...THATS Yankee ingenuity !

 

[smokeythecat]

Cool. Pure genius. I don't have a mower anymore. Bought a tumbler a couple years ago.

 

[dsdigger]

Awesome, and where you don't have duct tape, bungee cords are the next best things and ideal here. If you have to mow, might as well take advantage of the wheels spinning! Top cool invention of the week!

Thats where all the coins from the beach went. Great

 

[Stretch Da Truth]

Pretty cool idea!

Def MacGyver approved! If ya gotta mow the lawn might as well clean them coins.

Funny you've been doing this I've been using a square plastic peanut jar for the last few years attached the exact same way.

You run it dry or wet? What 'stuff' ya put in with the coins?
(Bought mine fro doing some ball milling)

Weed eater fail, coins flying everywhere.......just sent the girlfriend to the grocery store, two small jars full of coins and some wire ties, I'll let you know how the grocery cart experiment works out.

That's creative, 2 thumbs up

Put them in a jar and let Terry Soloman stare at them a while...they will shake themselves clean....

Square is better. Great minds think alike!

The coins have a lot of sand still on many so I don't have to add an abrasive, like sand, to the coins. I tumble them dry. 45 yrs ago I worked in Industry and we'd tumble clean certain auto parts and add a scoop of sand to act as an abrasive, sort of like sand-blasting. 30-35 minutes seemed to do the trick. Crushed my 3 middle fingers on my right hand by a forklift (with my weight and forks weight) as I was riding the forks lower from just dumping a container of car parts into a large tumbler 5 ft off the ground...had gloves on and just knew when I pulled my glove off I'd find totally crushed fingers...but I digress, another story another time.
