Looks like 16 TPI
Thanks to Jeff I was able to make this and successfully adjusted my (ahem) nuts.
I had a 1 foot piece of 1.5" galvanized pipe, and although welding would be quicker, there is some fume danger** there and it was raining outside. So with Jeff's measurements I popped open Fusion 360...wait I am a hobby guy, I don't have fancy stuff like that! I mean I popped open paint, excel and the snipping tool and got to work!
It occurred to me that I should measure it in metric too because the the numbers are dead on in a lot of cases. I used the lathe and the mill to make the end caps but it all could be done on the mill. I like to use my angle grinder handle on shop made tools when it makes sense, just drill and tap M8 thread and instant handle!
**Also PSA, Don't ever weld something after using chlorinated brake cleaner, it can create phosgene gas which will seriously maim or kill you!

Bookmarked. I need to adjust the backslash on mine. Need to see if it is similar procedure for my Wells-Index.
Had an issue where the machine pulled the part and ruined it. I know, pilot error, but it showed me than the table slides more that necessary…

That is why mentioned being user error... but I need to validate if the nut or screw (or both) have excessive wear... it just slides too much. I will document findings in my ownership thread.
