Just a note, instead of trying to hammer the coat hanger flat and drilling a hole
If you have access to a bench grinder, grind one end flat on both sides then carefully bend it over onto itself making a loop
Then spin the other end against the wheel and make a nice needle point.
Saves alot of hammering
If you're going to do pictures of the whole thing, I can submit pics of my eel needle, it actually came out quite nicely... prolly use it for rigging whole bluefish for shark also...
Cheers
