When i made mine i got the brass fitting from a plumbing store. I took a Hex (allen ) wrench that fit tightly inside and cut off ( L ) at the bend so that it would fit up inside the brass fitting. I cleaned up the 2 different metals with sand paper so that i could braze or solder the Hex to the inside. The biggest problem was making sure that it was absolutely straight so you don't have a wobble when turning at higher speeds.
