You cant make weapons in borderlands, you find them, (i finished game)

Crawmerax cannot drop gearbox weapons
The only way to get mod weapons is to hack or become a mod so good luck.
Go http://blmodding.wikidot.com/how-to-mod-it and over on the left side there is a section that says "Modding Borderlands" and many sub-sections with different tutorials. Basically you just get a save file of the internet and transfer it onto your xbox basically. or go to google and search willowtree for borderlands
Willow Tree is editing software for the Borderlands video game. It allows users to 'cheat' at Borderlands by changing what weapons they carry, the statistics of their character, and alter or mod the different levels and quests in the game.
i have found a couple of people who do and you can make your own in willowtree
You keep all your weapons and skill levels when you start the second play through.
