3D Grappling Hook shape skewing *PLZ HELP*

I am in an entry level game design class and I wanted to do something cool as far as movement mechanic for my game. I followed a rather decent tutorial by Sykoo on youtube (https://www.youtube.com/watch?v=MR1XK-q265E) on how to make a functioning grappling hook inside of unity.

Seemed awesome... Seemed doable...

However once you start banging the hook object around a playfield the shape of the hook obj begins to distort and grow in size.

I have read through a number of tutorials at this point recommending parenting to an empty game object. I have tried parenting the various components to empty game objects, but that hasn't changed anything for me.

I have been thinking about using an Instantiate approach, but I am a little lost with that process...

Any ideas or suggestions on how I can get this working correctly?

I have attached a picture of the object before and after a few "hooks" to illustrate my woes.

Thanks!
