Ashlyn Katarzyna:
This is interesting, I like seeing rebuilds of machines from restorations to more accuracy.

Hey Guys, thank you for the kind words! :beer:

I hope it gets more acurate, when I am done with it...but even when not, it has a cool new paintjob :)

Here we go with the cross slide...first scraping the top surface even:

Progress...

Better...

Thats good enough, I think, the whole area has a pretty good contact pattern:

Again, machining pockets in the lower bearing surfaces, that will be filled with moglice:

The casting progress, the Tape stops the moglice from flowing all over the surface plate.

Released and cleaned:

I wanted the side of the cross slide also rectangular to the top (and automaticaly to the bottom) surface, so I had to scrape it...

First I had to check how much it was of, so I setup the dial indicator in the stand and placed my precision square against the foot of the stand (and against the feeler of the dial indicator), and zeroed it.

Now I could measure how much the surface was off. The indicator shows -0,184mm, that means, its tilted to the right.

Countercheck with a square:

Scraping...getting only a few points so far:

But I got pretty square by now.

Again, counterchecking, thats Ok :)

One little thing to the end...
The play of the main spindle is adjusted with two nuts, but they where pretty rough on one side. That made adjusting them a bit complicated... :doh:

Easy job for the surface grinder at work:

I have a few more pictures left, they will follow :D

good night
Stefan

David Jupp:
On what basis did you decide how big to make the pockets for Moglice ?
