Thanks everyone for their input. I do not have a lathe, but I do have a drill press. Not the same but it may help. I like the nail idea, I also have some thoughts on using steel tubing.The narrow blade insert is also a possibility, especially since I work for a company that fabricates stainless steel equipment, cut with a laser (not quite primitive, but it is an older laser). I will post an update once I get something made.
