vtsteam:
I tried the tailstock on it.

NormanV:
Will it be the same tomorrow? I only ask from the frustration I have experienced from earlier scraping jobs.

vtsteam:
i don't know Norman, I can't predict the future! I certainly hope so. It was the same ths morning as it was last night......

Anyway, this evening I measured the thickness of the ways all around, inside and out along 5 stations and I wasn't able to measure a thickness variation -- my calipers are good to .001', so I can't tell any better than that. But i don't think I will need to do much if any scraping on the bottom of the ways. I'll know better when fitting the carriage. Maybe there will be a tight spot that needs a little work.

The closeness all over surprised me, because i knew i had taken more off in some areas than others. So I measured two cutoff pieces of the way stock -- They also measured the same all over. So it's pretty obvious that scraping really takes off a minute amount of material each pass. I probably did 20 passes and rubs and stonings over the last 2 days, thinking i did a lot. But not even a thousandth of an inch was removed.

Earlier today, I bought a 3/8" thick by 1-1/2" bar of hot rolled steel from Lester to make a narrow straightedge in case the underside needed scraping. A special straightedge would be the only way to check in there.

i also checked the widths of the ways gap and outside dimensions. The sides of the ways wll need some scraping as the tailstock is a tight fit at the ends. I knew the way stock was bowed very slightly when gluing up. It looks like about .004", worst case. That would be slow scraping on the top side, but should be faster on edge. I'll need to make the straightedge to start a reference edge on the ways.

I also watched that video and was wonering about the orange pre-rub?
Anyone any ideas?
