I am a hobbyist, new to machining, and I would like to make a fly cutter. Seems to be a typical choice for the budding hobbyist, and I don't have one.
I have some scrap pieces on the shelf. Two of which I could use to make it from a single piece (3/4" integrated arbor). One is 4140HT and the other is 12L. My lathe is a South Bend 13". I mostly use carbide insert tooling, but occasionally some HSS tools (I am not the greatest at grinding them yet, but I manage to get lucky every now and again.
Which piece should I use, the 4140HT or the 12L?
