First let me say that I have quite a bit of lathe bed wear because the folks that owned the lathe before me, TVA, did not do enough maintenance on the lathe and the oil pump in the apron was not working. The wear on the carriage V-way is about .014" and on the rear flat it is about .007". I can not afford to have someone regrind the bed for me, so I have to live with what I can do myself.

This means that the V-ways are less than 90deg where the wear is greatest, and because of the wear difference between the v-way and the rear flat, the wear rotates the entire carriage down in the front where the wear is greatest. Additionally, the wear means that the bed is concave (sway backed) over part of its length (at point of maximum wear) and convex over the remainder of its length. All of these factors mean that oil will not stay under the saddle and no matter what I do the saddle will wear abnormally.
No amount of scraping of the saddle will fix the wear on the bed so I decided that I would forego scraping on all the work I did on the lathe. Even without scraping, the work I am doing on the lathe is making it better than what it was when I got it.
I am well satisfied with the Moglice. It made a nice surface and appears to be quite hard.
In the next posts, I will outline my observations, what worked for me, and my suggestions.
