Poker is "music wire" from the hobby shop, it is similar to spring steel, very strong and flexible. I used a diamond cut off wheel to put in the serrations, actually they are spiral grooves cut at an oblique angle to the shaft, and in opposite directions to provide some cutting action. I don't have a jig to rotate the shaft in, so had to do it by hand and as a result, they aren't perfectly even, but what the hell....
Shoot!
I haven't done any Quality or Acceptance testing on this thing!
Quick!
Somebody send me some plugged Cubans!
