Creating a Custom Modification to Armor - How?

[9raxus]

I am attempting to create a piece of armor that has a custom upgrade that is available at the armor workbench. I am unable to achieve this despite trying to emulate examples found in the Creation Kit.

 

What I have achieved so far:

 

** Creating the piece of armor itself

** Creating the armor modification (OMOD).

** Creating the recipe for the armor modification

** Attaching the recipe to the armor modification and attaching the armor modification to the piece of armor (supposedly, based upon examples in the creation kit).

 

What I can't seem to do is get that piece of armor to appear at the armor workbench menu and, by extension, the upgrade.

 

I know how to create objects through the chemistry workbench but, for some reason, I am having trouble creating this type of mod. Any tutorial or assistance would be appreciated. Thank you.
