As long as you plan on scraping them someday. I would also buy a round stone and chamfer the oil groves. If you leave them sharp the oil won't flow out of them. They will sheer the oil and it will stay in the groove. Another tip, before you move the saddle move it the opposite direction to get an oil film under the ways. Once you get around to scraping new oil pockets in the ways it will feel like it's floating on a cloud. You will have a lot of stick slip now. It's like rubbing 2 gage blocks together when the ways are like that. Remember this condition will get worse and it will score next. Be careful and good luck.
