Blender Nugget: Using Array and Curve Modifier without the Curve deformations (shrinking/fattening)

Hopefully this posting helps on any other soul looking to do something similar.

So, I was on a seemingly small journey: A spring (or repeating/merged object) that arrays and follows a curve without deforming terribly:

I just used a screw modifier then arrayed it and fit it to a curve, but it deforms on sharp curve edges as shown above.

This is what the object looked like in edit mode.

I tried reducing the screw iteration to 1 on the circle and then I parented it to a plane, and then made the plane to take the array and curve deformations and used instancing like is shown in this Youtube video:

But, even using this method I could not seem to figure out how to make the screw piece mate up to itself. I was sure the solution was fairly simple. But this didn’t look like it…..

Until I came across this forum posting which got me 99% of the way there:

Everything was working great until I added the skin modifier on a very small spring and it looked like this:

I kept scratching my head until I realized I had seen this problem before. The SCALE was way too large.

Just had to go into edit mode and scale down the skin (using CTRL+A) by like 100 times and I finally got what I was looking for: A spring that arrays and follows a curve without deforming terribly: I took things to an extreme here below

This is the curve I was trying to actually get my results on:
