This awesome thread is droded's, not mine. You need to get the weapon into your inventory after you have used his guide to make it.
OldBoy explains how to do that,
1. Start Fable Explorer (get it
here).
2. Look for CREATURE in the scrollbar to your left.
3. Double-click CREATURE and scroll down until you find CREATURE_HERO (it's number 1470) and double-click it.
4. In the new window click on the [+] in the left panel and scroll down until you find
Weapon 1 and click on it.
5. Now put the object ID of the weapon you want to add to your inventory. (In the case of Sword of Aeons it's 5526.)
6. Click 'Apply Changes' in the CREATURE_HERO window.
7. Then, in the top bar in Fable Explorer, click 'Actions' and 'Save mods and run Fable'
8. Wait till Fable starts.
