Just wanted to thank everyone, threads turned out good. Didnt break anything the first time around.
To anyone who is looking here in the future, i used this guide to calculate feeds and speeds, it was dead nuts. 4140 pre hard, 5/8x24 threads. Ran 5730 rpm with 11 ipm
Only thing i want to note is on the thread depth i set it to -.005 initially so my thread would be tighter but i probably should go -.007 or 8 because the cap was a little loose. I really need a go/no go gauge.
Instructions are clear on the harvey tool guide but here are Feeds and speeds calculations i did in case someone needs to visualize how its done on paper.
