Turn that screw underneath, it should improve the situation.

(the larger one in the center, not the small one)


Been working it and oiling it, however, I still need to tap the underneath of the table to unstick the table after I tighten and loosen the table.

I think the one on the right is for picking the stake out of the box. That other one looks home made it doesn't match the others. About locking, have you unscrewed it all and cleaned it all out?


Yes I have cleaned it. I adjusted the big screw on the bottom after oiling the hole and I can loosed the table by tapping the edge with a screwdriver. Then I align the hole and and turn the knob at the back to rotate the internal cam, and it does lock. The problem is that when I loosen the knob and thus the cam, the table only loosens slightly and I need to knock it again with a screwdriver to free it up. Would love a cutaway of the stacking tool. Any suggestions. May be internal corrosion.

the table should come right off when the screw is removed, and the knob pulled out. Maybe you have corrosion or gunk under there...


I can't actually pull the screw out after removing the bottom 2 screws. It seems to jam. But what you are saying is that once I pull the rod out the back. The table should lift straight off, correct?

Jdrichard,

The table locking mechanism is a crankshaft type of cam similar to the mechanism used to lock in the head and tail stocks of watchmaker lathes. These mechanisms can become worn with use and may require some machining techniques to bring them back to working order. To isolate the problem place a small shim (tin foil) between the locking cam and the hole in the shaft that pulls the plate down. If it now locks then that is the problem. To fix you will have to build back the cam or the hole.

Update on seized staking set. Took out the locking screw and loosened the cam shaft and then knocked out the shaft with a small hammer (scratched the nickel plating on the side a bit, but it needed convincing). Then I removed the table by knocking it with a punch from the bottom. The complete lot fell out. Then I took 1200 grit sandpaper and sanded the hole where the locking cam fits . Did a bit of this as there always some corrosion. Lastly I cleaned the table in lighter fluid and then alcohol and then I re-oiled once dry. Reassembled it and it works like a charm. Loose until I turn the back dial and then tight. Then turn the dial again and the table is once again loose.

Thanks guys for the help and suggestions. I am operational and will be knocking on the balance and roller table once I get the right jewel for a 21 J Illinois PW I have been working on. I am in deep now and have a jeweling set coming in the mail next week. Seitz full set.https://vimeo.com/183234528

      Rolex Cal 1570 Balance wheel rubbing

      By Jon · Posted

      Here's a quick Gif I made to show truing the balance using callipers. This has such a slight wobble, but is within acceptable parameters. The important thing is the balance doesn't touch or rub anything when in operation. This is an Eterna Tank. Here's a pic of the balance freshly rivetted with a new staff in the movement

      I just poked an inflation calculator, and $5 in 2020 would be about $6 in 2024. Doesn't fit very neatly into any status codes, which stop at 5XX, but that's honestly somewhat arbitrary outside of a clever pun for those that dabble in such things. Back during the pandemic, I would spend a good chunk of idle time in the evenings scanning through hundreds of listings a night, and I would only land 1-2 a week max. I would often go months without finding something suitable. A very small percentage of the watches in the price range are worth pulling the trigger on for my purposes. The number floating through the thread here may be somewhat deceptive.

      Balance cock stud screw

      By Zedster · Posted

      Hi, guys I got there in the end after several attempts using a screwdriver and Rodico, I couldn't wait for the tool to arrive and was getting pretty confident handling the stud screw without it flying away. At first, I was using far too much Rodico, and then realized you only need the smallest amount inside the screw slot. Putting the cock back onto the movement also helped as it gave me more to hold onto while my shaky hand tried to align the screw wobbling away at the end of the screwdriver😁 Anyway, job done and I can move on. Thanks again for all the advice it's really appreciated for a beginner.

      the escape wheel can't move itself

      By nevenbekriev · Posted

      You need to know at least the basics. Then the questions that You ask will begin to make sense. From what is seen on the video, the gear train and escapement look fine, but the balance doesn't rotate free. I can suppose that the thin gold colored shim that must stay under the balance cock is not in place.
