Few more hours. Roughed out where the stuff is mounted for the rear z axis, fabbed ball screw transition plate. That was not easy in metric keeping track of where everything goes so it bolts up with a 3mm offset.

Another piece done this morning. 3 hours start to finish. There are bearings captivated inside there. I'm going with one bearing support on the roughing axis z ballscrew. Quicker and don't need precision there. An additional shot of where it goes.

white arrows are the pieces I got done today, plus have the z axis ball screw setup now too. Pink X is a screwup hole. ugh I forgot I had to offset the rails to clear a screw hole :-[ :-[

What do you do when you need a 15mm metric nut for a ball screw bearing...

you make one.

Find a nut in your junk box. Mill it out and tap it, then machine the end so it only contacts the bearing center not the shield.

Going back onto this tomorrow. The x axis ball screw I got came in today. Wish that guy had another. $800 ball screw for $59. Brand new.
 :)

Should have one fully moveable X and Z cross slide table tomorrow and be able to start getting small things like belts measured and ordered. Now can make guards and tooling fixtures when finished height is known.

WOW....              You are GOOD!   Did you do an apprenticeship as a machinist, now one by trade...Self taught?  Then on to "Plug Making and Design"?    I can open a beer bottle without an opener...Picked that up in the Army. I'm happy with that. :dance:

So yesterday was just one of those days where everything went to shit. It seemed like it. I made the bearing block twice. ugh. I frigged up on the first one. Had alot of problems logistically getting this screw installed...there's alot to do to make this happen. Everything has to be just right or it will bind at either end of travel. No binding front to back. Had to make another nut too, that's a drill stop in there :)

Finished this up this morning. This is the x axis for the roughing side.
