if i'm in a hurry i make mine from a 1 - 1.5" wide 3/16" thick piece of flat bar.... you can use a tubing notcher with a 2+ inch hole saw bit at a steep angle to get the U shape on the end.... after a minute or so of grinding it can look real nice but keep in mind it will never be CNC clean.....
you coudl do the same with a mill or drill press. you could probably do it witha hand drill if you had a long pilot bit and patience.
if i can remember to plan ahead i always call dan @ ruff stuff.....
