Had a visit from Mal of Australian Metalworking Hobbyist this morning.
We dismantled the Extended Cross Slide on my Hercus 260 Lathe to examine & get some dimensions.
Anyway while it was apart, checked it for flatness, it had 3 thou (.003") lengthwise convex on its base slide.
Spent the last 3 hours scraping it flat using the granite surface plate & blue.
Then scraped the cross slide saddle to match. This section was surprisingly flat & accurate, requiring little attention
The Extended Cross Slide had obviously moved over time, through stress relief.
All is now good !!!
Learnt a lot in the Scraping Course in Melb. (Thanks Phil) a couple of years back.

Bruce
