How to scrape lathe ways

I have a 10K South Bend lathe that needs to have its ways ground,
scraped, or both. I can feel a lip of 1/32 or so on the V way of the
lathe. My local machinery dealer told me it would cost to much to
have it sent out and ground.

I have never used a scraper before or saw anyone using one. I have a
feeling that scraping is a learned skill and do not know if i should
attempt it.

One person told me i should start with a belt sander and finish with
a scraper.

Does anyone have any advice on what i could do with these ways. Or
have any links describing the process to bring the ways up to spec.
