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.
