If you have a lathe, this looks like a very nice beginner's project. Start with a rod of the right diameter; a simple way to get such a rod is to buy a long bolt, because those are mostly not threaded. Failing that, get a length of "drill rod" from a metal supply outlet. Then all you need is to grind a tool bit (high speed steel) to form a narrow screwdriver-like tip to cut those grooves. Hold the rod in the lathe, cut the grooves in the right spots, cut the thing to length, done. paul
