What's the extra spigot poking up/down from the nut mount for?

Something to hold on to when I turned the other end
After much angle grinding and filing the bed slid comfortably past the nut housing so I put in one bolt to fix it to the carriage. First pic. Not very brave but it's easier to move one misplaced hole than 4. It isn't defying gravity, there's a roller stand supporting it, makes it real easy to put on and take off.

Then the driven end, Pic 2, it sticks out a lot so I can use more of the bed, got this very wrong when I first CNC'd it so this is a slight overkill. This end is in 3 pieces, which is okay because the screw will hold it in tension with the same quarter ton I put on the Y. I plan to Loctite it in place when I drag it all together with the Bellevilles.

Then the handle end...

I haven't cut the bearing seat in the handle end yet, wanted to get my calipers on it first, Pic 3, and find out exactly how far the shaft sticks out.

Next I put that measurement in the drawing and decide how much I trim off and where. I have leeway.

The last pic was supposed to show that my single bolt went in the right place and the shaft is concentric. Would have looked a lot better if I'd put the camera a couple of inches to the left

The Y axis feels amazingly precise from a backlash point of view. The dial test gauge will reveal all.

More soon...
