Spent two evenings rescraping the base of the headstock on my Denford lathe, and the mating surface on the bed.
Got it absolutely spot on, aligned perfectly, contacting all over, was lifting the head to move to another bench and I only went and dropped the bugger
from chest height onto the concrete floor. Put two big dints in the floor.
Blued it up again afterwards and it's well out, the whole thing has skewed a bit in some way. The spindle was installed so hopefully it held the bearings in place and I can "just" scrape it back again!
Luckily if it is knackered i actually have a complete spare head, which is a godsend otherwise the lathe might be scrap!
