Rad-E Spinner: World's First Radial Piston Spinner

::: Introducing the Limited Edition Rad-E Spinner ::: Made in USA
Hi, we're TFD. TFD is a small family business located in North Carolina, USA. We make unique tools and other gear. The Rad-E Spinner is our latest design. We're here to share this project with KickStarter's that appreciate great design because that is what the Rad-E is all about.

Only the first 200 units will be serialized with a signed Certificate of authenticity from TFD.

This unique all-metal spinner has the same cam-driven, piston  action as a tri-piston radial engine. This newest project is the result of many months of design iteration, testing, and design refinement.

First, let's talk all metal construction:

  • Brass pistons
  • Boca SR4 hybrid ceramic bearing (SI3N4 balls)
  • Stainless steel hardware, frame & connecting rods
  • Natural and Flame-anodized stainless steel finger caps (cupped and spiral cut grips)

Custom Engineered Parts:
Rad-E Spinner starts with the 6 custom fabricated parts (2 brass parts & 4 stainless steel parts). Cutting and shaping quality materials isn't easy, and materials were chosen after evaluating very low-friction interfaces for the piston motion.

As a mechanical engineer, I love engines, machines and anything mechanical (yeah, I know, very geeky, I'm just keeping it real!), so I wanted to make a cool looking spinner that incorporated moving parts.

We've designed the Rad-E to be easy to assemble and access the bearing,

Dual-sided piston pumping action!

This design originated from 2 ideas:
1. I really like kinetic designs that have more than one dimension of motion and,
2. I've always been fascinated by the mechanical motion of radial piston engines used in aviation.

Risks and challenges

This is our 4th KS project and we have learned and improved from each previous campaign to develop strong internal processes for getting things done. Also, we have partnered with reliable suppliers for raw materials and parts fabrication.

There can be issues that arise during any project, however, our experience will allow us to adapt to any challenges. We know that on-time product delivery is most important to our backers so this is our top priority throughout Rad-E Spinner project. Our schedule is designed to have ample time to meet fulfillment times listed in the rewards. As always we keep our backers informed and updated.
