Anyone have a clue which spring that the flyer arm uses? I am just curious and would like to know. As I recall the spring wire is about .187 diameter with the coiled diameter about 1"

Michael,
The spring has a diameter of 35mm, the wire is 5mm thick, total length is approx 285mm and there are 18 coils .

Gentlemen thank you for the mm dimensions & the inch conversion.
Thank you,
Michael
P.S. Anyone got a part #?

Hi Michael. If I'm thinking what you're thinking then you probably know it's not just the spring specs that you will need to simulate the charactistics of the flyer. It's also the placement, angle and positioning of the spring within the arm. I guess you know that already.  |

Charles,
You're absolutly thinking what I'm thinking. There is that very particular subtlety about the way that spring behaves that I am trying to find out here. And I know that you know what I mean Charles.

I stick by my guns the X2 solves that problem and more.

EDIT: Fine, I give up. Shoot me down all you want. I just don't want people to use this forum to do things that if not illegal are completely unethical.

I'm not sure but I think most of the patents that pertain to the majority of the design are expired.
Most of the latest patents are for subtle improvements.
That’s why in the last 5 years there has been an explosion of rigs on the market. All of which in one way or another were “reverse engineered' from the original; Steadicam.
Can you show us the statute about reverse engineering, I have never heard of it.

Also the, “for profit” applies to using it in a commercial fashion. Although unlike copyright law, there is no criminal action associated with patent infringement.
It is simply a means to build a case in a civil suit. And as such, it is highly unlikely that anyone would pursue it.

There are no patents attached to the flyer, Tom, and since Michael attended a workshop AND flew the rig, I think he has a pretty good idea of how it works.

Tom--I seriously question your comment on ethics. There is no one on this forum that is unethical or a thief. The Steadicam patents have expired, If you can figure out how to make one, you can. By your statement, your copying of an Ultra sled is unethical. By your statement, Cody's 3 spring design is unethical. Mikko's flyer type arm is unethical. Perhaps Charles GPI Pro type arm is unethical? Think before you speak, for God's sake!

My comment on ethics is based on if someone were to try and start mass-producing and selling something like that. I just don't approve of people profiting off of other people's inventions. It drives inventors out of town, stifles creativity, and is purely bad. I'm not suggesting anyone here would try that, I just want to make sure that I don't help someone do something I consider unethical.
I need to do some more building apparently, because my temper is still apparently coming out where I have no intention of it coming out.

Tom,
Forget temper. Temper is for changing the hardness of metals. This is a discussion of rig building and the subtleties of engineering machines.
I have written extensively on this subject in other threads but I’ll review it here.
The spirit of a patent is to give an inventor time to make money off of her invention. The reason patents expire is to promote commerce. If patents never expired it would stifle innovation. So the patent is a sword that swings both ways.
On the one hand it promotes innovations by protecting; and then it promotes it by letting others join the process.
Can you imagine if the airplane patents would not have expired, or the automobile. We would all drive model Ts and in black.
There is nothing inherently unethical about copying other peoples work even while the original patent is still active. There is a provision in patent law called an Improvement Patent. So even active patents are somewhat fair game.
Remember the purpose of patent is to promote innovation.
