Very nice work Dick! Beautiful really.

I have a question though, is there any wisdom in trying to make these out of 4340 HT? I have a round bar of this material but to be honest it is a challenge to machine. I’ve made a few small parts out of it and let’s put it this way, it is unforgiving when it comes to feed and speed mistakes. The other option is to buy some 4140 or similar material, the bar however only cost a few bucks.
