I just wanted to be sure about the order of drilling / welding the various bits on the spider (10 40 432).

- drill and tap six holes, M8 (10 40 432 D)
- use temporary bolts to hold nuts (10 40 432 W) and bearing supports (M1 20 220 T) in place on the spider
- weld the nuts and bearing supports
- remove temporary bolts and flatten the spider as necessary.

Does that all sound correct?

Yes,
And if you really want to get the set up even closer, you can do the following:
- drill slightly oversized holes and do not tap
- use temporary bolts to hold the bearings, spacer and REAL z-slide in the NUETRAL eccentric position
- weld nuts on back side
- remove and flatten as necessary.

This method will ensure any inconsistencies in the grinding of the vee profile on the z-slide are accounted for in your layout on the spider.

I have had a lot of practice at this....to date, I have manufactured 7 spiders with this method. (I like the practice) :)

Good luck.
