Dug up some info from McMaster Carr for pinning a 3mm eye;
Drill bit size conversations:
#31 = .1200" prt #2901A205 (.005" difference)
or
3mm = .1184" prt # 30565A249 (.069" difference)
Rod:
1/8" = .1250" prt # 8953K101 for 1' brass +/- .003"
all the parts are <$6
drill bits are black oxide - split point keeps the bit centered w/o pilot hole
135* = smaller chips
