So I found a long lost Jacobs Chuck

The Chuck wouldn't open or close without considerable effort, so I decided to try fixing it. I watched a utube video by Tubalcain and said to myself, "I can do that".
I messed up by not taking a before pic, but I was to excited just finding the dadblamed thing. So I
commenced to give it a 5 hour bath in White Vinegar. Never done that before, but it worked really well in removing the rust. Stripped the chuck down following the video instructions and it was gunked up and rusted in places. Following the bath and sodium bicarb rinse I flushed everything with WD40. Then the process of wiping the parts down and to my amazement all the rust was removed but staining remained. Some buffing and lots of the staining was removed as well.
FYI, if you ever do this little job, pay very close attention as to which jaw is #1, #2, and #3; you'll have real trouble if you don't. The slots where the jaws reside are clearly marked as to 1,2,3, but as I discovered, the Jaws aren't. I finally stumbled upon mill marks on the backside of the jaws; one was a long mill mark; two was a little shorter and #3 was the shortest mill mark. Only took me a little over an hour to discover the marks. I did do a photo array of the reassembly but I won't post that unless anyone is interested. Great way to spend an afternoon in the shop.
She spins open and closes nicely but I'm pretty sure it needs a kit. Going to use it first to see how it goes.

Good job, Gary. Restoring neglected tools bought cheap or salvaged from the depths of someone's forgotten treasure box is very rewarding.

One thing you find very quickly with old tools is "they don't make them like they used to anymore".

All the tooling for my 6 X 30 Atlas lathe is of the same vintage, 1948 same as me. So seldom, or never used, tooling has to be cleaned and serviced before I can use it. You did a fine job! It was fun right? Love making old things work again.

It indeed was fun; that is when I finally located the mill marks on the chuck jaws.:)

Oscar--- a drill chuck made by the iconic Jacobs company. Standard key type of
drill holder found on the front of hand drills and bottom of the quill on a drill press.
Some non-Jacobs are OK, but AFAIK, all genuine Jacobs are good stuff.

Resurrecting a quality tool is always a wise investment of time and effort. My problem is finding the time. I have at least one Jacobs and probably two Albrecht chucks that need a tear-down and cleaning.

I bought several recently, for myself and for my workplace. All were genuine Jacobs, which today I believe are made from genuine Chinesium like just about everything else (do we produce ANYTHING in this country anymore except Toyotas and household waste?) The quality seemed good on all of them, though. The ball bearing one I picked up for the shop's 3hp drill press is made like a Swiss watch.
