Humble script request

These are very cool springs. They make great electrical connectors in medical devices, and electronics.
Of the many patents, Peter J Balsells is one of the main creators.

In one patent, the springs are not just a simple helix of steel which is pushed into a groove, circular or otherwise.
During the winding, different angles are created in the steel.
Contrary to this, the thesis formula appears to be symetrical in the z axis...

For a script, I would make the assumption that the spring runs along a straight line, not a circle, and then use flow. (?)

One iteration would make one coil, of 1/w offset.
To script along a circle, I think would require another equation, which would rotate each coil around a polygon, (or circle).
The polygon would have the same number of sides as number of coils.
Or the circle would have to have the correct circumference to accomodate an integer number of coils...

Michaels method looks excellent for viewing the circular canted coil.

A script would be fairly easy, I think.

Hi Brian, does that one match the script above? It looks like they have different names - CantedCoilSpring.js versus CantedToroidalHelix.js ...

Sorry, it is the same htm.

I've dropped toroidal thoughts for now.

Wrote a canted helix script, but of course it does not work.
It sort of worked for a while, but now I've completely broken it. :-)
I always get messed up with t = 1/(number of something). And number of coils per unit length.

Got the CantedHelix script to work.
It was necessary to adjust the formulas.
(The use of w had to be modified.)

Picture:

I suppose it could be turned into a toroid, without too many hours of work?

Hi Brian, yeah what about using Flow to bend it around a circle like you showed earlier in this thread?

Flow should work great!

I'm curious if the skewed helix is the same as a canted one...

The script does't set the length like the MoI helix command can...

Yes, these are very cool springs! Making a lamp that can twist... Still very much in progress.

The script works perfectly in combination with the Flow function.
Thank you very much, both of you.

Best,
Morten
