r/machining

Not sure if this is allowed but I figured this community would know....I have a home shop setup with a 1998 fadal 3016....my issue is that I have had to frequently empty the water separator that is mounted on the "in" side of the air dryer. I understand this is before the dryer is pulling the water out, but i installed my compressor up in a stairway so i need a ladder to reach it, do I have it hooked up correctly? What is a better way??? Why is there a separator when that is the dryers job?

Thanks for the help!

Greetings,

I am disassembling a VDF 18RO lathe and on a few shafts bores in the headstock there are these seemly pointless holes. They are tangential to the bore thru which the shaft goes and they are a blind and countersunk M4 thread.

Any idea for their purpose? Are they used to help disassembly?
