Stainless Steel Signal Coins

Happy Weekend Everyone!

We're still battling winter up here in the northeast. My driveway is a disgusting mess of ice and sleet but it won't be hanging around for long as 50F temps move in this week. Spring will not be denied for long.

Projects continue to barrel along at a terrific pace. I am developing a new spinner/fiddle item and that project is well underway for the middle or latter part of April. The upcoming K4 Keytons are actually close to ready, just need to do some more anodizing on them, but they will be next up. And there is a wide assortment of other things all happening at once. I need to get back to working on the next steel tools but unfortunately there is still just one of me, so progress at the grinder has been slow this past week.

In the meantime, my favorite new toys are rapidly evolving and some very cool stuff is on the way... starting today! And Spin Coins are no April Fool's joke I can assure you. Dang these things are so much fun, I literally cannot put them away. :)

The first Spin Coin offering is the Disko Signal Coin. These are the first of my SpinTool series which will include spinning coins, spin coin game pieces called RaceCoins, also ArtKoins and some new and different fiddle tools and fidget toys. Lots of busy fingers ahead for everyone I think!

These first batch of Disko Signal Coins are made of 303 stainless steel. Measuring in at 1.5 inches in diameter, same as a silver dollar, they are a full 1/4 inch thick, plus a little more added on for the foot. The deep rifle knurling makes for a positive grip and the coins spin smoothly, riding on a beautiful black 1/8 inch ball bearing made of silicon nitride.

The low center of gravity combined with the heavy 36grams/1.25oz weight provides a satisfying spin and the hollowed out bottom pushes the weight to the outside, further contributing to the stable gyroscopic effect. Any initial wobble will usually right itself quickly as it settles in, turning for a very long time. I have so far measured an amazing 8+ minutes on tempered glass in the best of my many spin tests. Not too shabby at all.

I have given these coins multiple steps of tumbling, etc and have arrived at what I feel is the optimal finish for resisting scratches. In addition, each Spin Coin comes with a small velvet pouch to help keep it safe from scratches in your pocket. I recommend these as perfect candidates for coin pocket carry.  

The mirrored center is mesmerizing as the reflected light causes it to wink and throb with every tiny wobble and bump. You will not be able to put these down for long, absolutely addictive... Of course, although tiny, they can also be used for closeup inspections of your face and as a signal mirror as part of a survival kit.

The Disko Signal Coins will run $70 plus shipping and I will offer first class mail for international orders again to help keep costs down for our friends around the world. The batch is limited in number and these are probably the only mirror coins that I will make for a while as I move to other variations, so I will make it a one per customer limit on them please. Thanks again for stopping in and hope your weekend is going great.

Sold out, thank you so much everyone!

Silicon nitride according to description ;)

"Silicon nitride bearings are both full ceramic bearings and ceramic hybrid bearings with balls in ceramics and races in steel. Silicon nitride ceramics have good shock resistance compared to other ceramics. Therefore, ball bearings made of silicon nitride ceramic are used in performance bearings. A representative example is use of silicon nitride bearings in the main engines of the NASA's Space Shuttle!".

Turns out Peter's been creating parts for a space ship.
