I think I found my problem with my dro, i have a lot of back and forth movement in my crossfeed nut , like I can physically pull back the top slide forward and back. I can make the nut , I just can’t figure out what size it is ? It’s 8 tpi , it’s the diameter that’s crossing me up.

I’ve watched every video from that fine man, like I said , making the nut isn’t the problem, I can even make another cross feed screw , I’m just wondering if this is some non standard size

15.63 is pretty close to 5/8" (.625")
I have a 5/8-8 tap , having trouble getting it to cut threads. I tried 1/2inch starting hole but the tap just spun. I think it needs to go slight under that

Is it a left hand tap? for a crossfeed screw, it needs to be left hand.
