You might think that penny slots just cost one cent to play. Many people have stories about winning big with penny slots. She was offered a steak dinner to make up for it. Some penny slot games are linked to massive progressive jackpots.
These can be truly lucrative, in the tens or even hundreds of thousands. But again, before you get excited, make sure that you read the terms and conditions to activate the jackpot. Usually, you will need to wager the maximum amount on each spin, or at least have wagers on every available payline. Since the engraving is only. Rather that turning the OD on the lathe I rotate the B axis while keeping an end mill rotating in a fixed position near it.
By varying the distance from the B axis to the end mill axis I can get very consistent diameters and excellent concentricity. The final photo shows a dial test indicator measuring the runout in the die blank after this operation. There was no observable runout. I used carbide engraving cutters at 10, RPM spindle speed to cut the images into the dies. Then, the larger areas of the images are removed using a 0.
More detail is added using a 0. The toolpaths for the engraving started as black and white raster images provided by the artists. I used ArtCAM to convert those images to vector outlines, then did my layout on a rectangular work area that would 'wrap' onto the surface of the die blank.
I used V-cutting and smart-engraving tool pathing to generate the toolpaths, adjusting the vectors slightly as needed. I customized the default ArtCAM post processor to use the Haas mill's G mode, which substitutes B axis motion for X axis motion, effectively wrapping the design onto the cylindrical die. The original illustrations were drawn specifically for this machine by a number of artists.
The images for the front sides, and the artists were:. I assembled the components I've built to date and produced and was able to produce several pressed pennies. However, much work remains to be done. I still need to fabricate the image selection mechanism, that lets the user pick what pictures they want on their penny and control the rotation of the die carriages and timing of the coin drop.
After that I'll make a case to keep the moving parts safely away from users, and create a more ornate handle. Question 1 year ago on Introduction. Hello, congratulations on the magnificent work. I would love to build a machine like yours. Would you sell the project in Solid Works? Question 2 years ago. Is there any way I could purchase some of your pressed pennies?
I am getting into making them as jewelry and even the fishing lures to sell locally. I would like matching sets for earrings and then jut some in both horizontal and vertical orientation for necklaces, keyrings, bracelets, etc.
Email me at justondean at gmail dot com if you want to sell some off. I'm still sitting here in awe after viewing your fabulous Instructable. I hope you don't mind, but I've added a link to your Instructable to my latest project, making Pressed Penny Wind Chimes. Your Penny Crusher is beyond cool. I'd like to give you a free one year PRO membership for the use of your impressive project link on my Instructable.
Just acknowledge this message to let me know you're still with us, and I'll send the code for the free membership your way via private message. Kudos, bravo, and all the well-deserved applause! Reply 6 years ago on Introduction. Does take awhile longer, but if it's commuter hours, or a freight train and you get the timing right I haven't done this before.
If the sole point is to produce medallions starting with a penny, there is a simpler solution, one that a vendor at a Renaissance Faire I used to attend had in operation for years. It used a tower with a ratchet mechanism to raise a striking die. The die weighed a few pounds, and the striking surfaces could easily be interchanged to get different patterns. You could even create movable type, if you wanted to go to the trouble of making hardened steel type small enough.
I thought about building something like this but was worried the dies would shatter on impact and had difficulty modeling the required energy. I'll have to look for pictures of what you're describing, or just try jury rigging something together. Don't know anything about the types of steel in the dies, but I know he would haul the striking die up maybe 15' or so with a hand-cranked ratchet, it would slam into the other die and the planchet, bounce a couple of times before stopping.
I think the two steel pieces were abut 6" overall in diameter, tapering to around a half inch where they came together. The striking part was probably about a foot long, maybe as much as pounds. I think he only struck copper or maybe bronze, not silver, but wouldn't swear to it. It generally only took the one strike to make the new image. Not sure he used pennies, i think he might have had his own blanks. I'd think something tempered more like a hammer or anvil, rather than real hard would reduce the chance of shattering, and still be enough harder than copper to do the job.
Have fun! This reminds me of the way one can make grommets. So depending on how thick and malleable the material is, it may not take as much strength, but enough weight of the die block to a waiting slug below. Just making sure the guide along the path to the slug is direct and relatively friction-free would be good.
Great project! Patting yourself on your back by using machines unavailable to almost all individuals reading your post is also great! Try letting some know where they can obtain dies at a reasonable cost and you might impress someone! I was looking in on penny crushers for camp thinking you could make a fishing lure with one.
A simple spoon or a small fish that a ring and hook could be attached later. What do you think? Penny lures. I think I'd want something other than copper to be used though. Not many fishermen dry their lures once they're done for the day -they'd corrode pretty fast. Perhaps you should ask mblem to make a die for your logo s and just run a few thousand blanks of suitable material and make the lures yourself, to sell directly to the bait shops for resale at the counter.
Otherwise, you need to be able to punch holes, add hooks and swivels, all while in front of the penny press. Not a kid friendly task let me tell you. I like the penny lure idea, but if you only need a handful of them I'd probably just hammer them out with a small ball peen hammer.
A neat little "mystical" feel. Probably why as an adult Im a sucker for Silver Dollar collector coins. I was just thinking the other day how the penny has been removed from our currency that press machines may make a return, adding that old mystical feel to that "rare" penny you find All of a sudden that jar of pennies I have as a door weight might easily be turned into magical dabloons to my kids and the neighbors kids It was so fun to see this coming together at Pier 9, and kudos for doing some of the heavier engineering I've seen in a personal project.
As a kid in HS I worked in the. Introduction: Building a Penny Crusher. By mblem adventures in chiminage Follow.
More by the author:. Pressed pennies have been around for over a century, at least. They started out by folks very dangerously placing pennies on train tracks and carving their own designs on the flattened surface.
When penny-pressing machines came around, pressed pennies started to gain even more popularity. These 10 facts about them will teach you all about these souvenirs.
To some, it may seem a bit silly to pay cents just to get a smashed penny with a design on it, but to others, it's an engaging hobby.
Some things are worth much more than the monetary value that's placed on them. Where did you get your first pressed penny? Do you still have it these days? At the World's Columbian Exposition , held to celebrate the th anniversary of Columbus coming to America, there were four different squished penny designs to choose from. This was the first recorded instance of elongated pennies. Flattening pennies on railroad tracks has proven to be very dangerous.
Many folks have been fatally struck by trains in the process, such as one Louisiana resident, as reported by the Daily Mail. The pennies can also turn into deadly projectiles that shoot from the tracks as the train whizzes by. Keep yourself safe and get your flattened pennies from the machines!
According to statute 18 USC Section , in brief, it's illegal to mutilate coins with the intent to use them fraudulently, but since pressed pennies are made as souvenirs with no intent to pass them off as currency, they get the green light. Instructables user mblem calculated that it takes 5, pounds of force per roller to properly squash a penny.
