Cody can't make his own weapons with his magic no. In fact it only just occurred to me he could use it offensively XD His Absolute Shield spell could be used to slap people in the face XD (...That's about it)
His magic is used by scattering his magic power into the air which he can then use to make barriers or negate magic/momentum. That's about the limit, armor was an advanced spell he wouldn't be capable of casting any time soon. Not really due to the magic power required (he's naturally high in that regard), however the mental strain on him would be enormous.
Or he can make barriers for people to run into. The Shield Spell is the only one which moves but (since he just condenses a chunk of his magic into one spot to move around). 

Anyway it doesn't bother me if someone uses barrier magic at all.

My question is why did you think he was capable of making his own weapons? I never considered it once. Armor was a fair enough thing to question, was thinking of bringing that in much later however.
