i recently made a full set of daedric armor but when i go to the grindstone i only see the option to make my battle axe legendary. what do i do to upgrade my armor , i have smithing at 92. any help would be appreciated

You need 100 smithing. Since there are no dragon weapons, daedric are legendary by default.

and just when i thought i was done making daggers

You don't improve armor at the grindstone lol. You use work bench.

sweet. do i still need 100 smithing or just more ebony?

Why don't you just check for yourself?

Also, enchanted items and potions for better smithing will help improve items even further. You can't got past the Legendary title but stats can be quite a significant bit higher than a 'standard' Legendary item.
