Build a smithy workbench with one level of Blacksmith skill, then make your own swords and pipe guns out of readily available scrap.
You will be able to build all standard pipe guns, and with Science skill you'll be able to build laser muskets.
"Blacksmith" adds five new swords to the game, and adds recipes to build the revolutionary sword and Chinese officer's sword.  All can be modded.  The mods for the new swords -- epee, smallsword, saber, court sword, and rapier -- do not change the weapon but represent the player's training and experience with a particular sword.  You'll need stimpaks and buffout.  
You will be able to craft simple metal armor.  There's also a blacksmith's hammer.
