So i got a bit of rust on the x ballscrew where bridgeport had an open are under the table. I have some bronze wool and some citric acid coming in. I figure ill try to get the rust off, and may even polish afterwards, not sure here. Its a $1000 mill so not sure how much it makes sense to spend on it. The screws seem like they are in very good shape otherwise.
The ways on the table look like there is very little wear and cleaned up nice:
One area I have been debating with myself is weather or not to replace all the way oil meetering valves. This mill is 25 years old, but clearly low hours. I have looked, and there are a ton of these things. I'm sure Id spend 500+ to replace them all. thoughts?
