There's lots of content in the archives on headstock alignment but i could find anything that addresses my specific questions. If there is an existing post, i'll apologize in advance for missing it. And now to my question:
I'm rebuilding a Monarch 16 CY x 54. The headstock on this machine is mounted to and registers to the bed via the rear inverted v way and front flat way that the tailstock rides on. Pretty much every sliding bearing surface on this machine is worn and in retrospect, maybe i should have passed on it but i'm already pretty deep into the rebuild so i've decided to do a complete job and have the bed ground. I currently have the bed off the pedestals and ready for grinding. When i removed the headstock, i found handscrape marks on the flat ways where the headstock mounts to these flats (both front and rear).
1. These lathes have hardened ways. Am i correct in assuming that the section under the headstock are not hardened in order to facilitate headstock alignment via scraping?
2. If i have the tailstock ways (inverted v and flat) ground, can I expect the same flatness under the headstock as the rest of the machine?
3. If i have the tailstock ways (inverted v and flat) ground am i correct in assuming i will need to align the headstock via handscraping these ways as was done during original machine alignment?
A project of this scope, particularly for someone with my experience level, has and will continue to generate lots of questions. More to come.
Thanks
