You can find them at Lowes or TSC you should also be able to get cable at TSC
I put the end in the vise open end facing up, heat it with a propane torch, melt the solder in it till it full then slip the cable into the molten solder. I continue heating it till the solder has soaked into the cable. Cool it off, clean it up slip the heat shrink tube over it and heat that with a heat gun.
