Lubricating a chuck

Recommended Posts

So in the process of restoring my lathe I got the chuck completely apart. Should I just fill it with the oil I'm supposed to use to lube it or should I put some grease in before I seal it all up?

Exactly what do you mean by chuck? I'm asking because it isn't possible to "fill" a lathe chuck with oil.

How about posting a pic of what you're asking about, I don't want to give you bad or possibly damaging advise.

The part that holds the metal.it comes apart, it's from an atlas 618 so it's old. They might not make them like this anymore.

A self centering 3 jaw chuck is a nice thing. Just a FEW DROPS of oil! No grease, ever. Not only will it catch: dust, dirt, grit, shavings, etc. but it will sling out when you turn the revs up. Say you want to put a polish on a shaft and put it in high gear. It's like standing behind a dirt bike doing a burn out in a cow pie. :wacko:

3 in 1 works a treat. A little is GOOD, a lot is B A D.

Greetings Pr3ssure,

           Be sure to assemble the jaws in the correct slot .. Note the numbers. 

Forge on and make beautiful things

Good catch Jim, I forgot about jaw order! :o

Man it's been a lonnnnng time since I looked inside a 3 jaw self centering chuck. 

Brings back memories of the first time I had a panic attack after taking one of Dad's apart and couldn't get anything to work when I put it back together. Dad wasn't pleased but just sat there and made me figure out how to do it right. Was I embarrassed when I FINALLY noticed they were numbered. Easy as 1, 2, 3. :rolleyes:

Yeah, I didn't think about that the first time I took them out. I got them all the way in and they looked a little wonky. I felt stupid to think they didn't have a specific order. How so you like my home made chuck key? Used a bolt and some rebar.

HEY! How do you think that makes ME feel? My Father just sat there rolling his eyes while I fumbled with his 3 jaw chuck I took apart. The really embarrassing part is how long it took to learn NOT to take things of his apart, it's not like I could ACTUALLY fix anything. Well, not really once I got something . . . apart it was invariably FIXED for good.

So, you got it off, apart, cleaned lubed and back together. Good job.:)

I've always had a fascination with taking things apart and putting them back together. I'm not sure why. 

Back when Boeing Surplus was alive, you could buy those giant old 50 lb mechanical adding machines for $ 1 each.  I'd pick up a couple at each visit as a kid and spend hours (days) disassembling them to see what the story was. Thousand piece 3-D reverse puzzles. Never re-assembled as I was more interested in small parts for other things but I do really miss those bygone days.  I guess I need to make more room in my life for stuff like that which doesn't require "results"....just fiddling for fiddling sake.
