[How do I?] "map" The Errors On A Older Lathe?

[jjtgrinder]

I am going to continue this thread under the "Sheldon, Logan, Rockwell" forum. It has become a ROCKWELL/DELTA specific now. Look for "RD14x40 Bed Twist".

if the ways on the bed of a Rockwell are worn, you can scrape in the carriage but the bed will need to be planed not scraped. Many of the Rockwell lathes have hardened ways and scraping is not practical for them. I have the 11 Rockwell, you can see pics of how I measured my ways by doing a search and you can see my king way tool, I also have been accumulating different indicators in the .0005 to the .0001 range. Someday I may actually have my lathe back together.

. Love " smooth and shiny", but
those grooves probably more nearly represent (at their peaks) the original dimensions than a new, shiny surface keyed to the bottom of the grooves. If you
scrape usefully, Everything Must be scraped to the bottom of the grooves,
upper surfaces, too. Beauty satisfies the Soul, but unless you understand the
above, the working surfaces will be Worse, not better.........BLJHB.
