Hello and welcome from Leeds, England. -
I'm fixing up another Landeron 48 - this will be my 4th one of these so I'm getting the hang of these a bit. I got it as a non-runner (pallet fork pivot broken, barrel tooth broken) and replaced those so that it runs ok. Reassembling the chronograph I've hit a snag. The watch stops when the chrono is engaged. I think the teeth are too deep. I think the eccentric to adjust that is on the hammer, circled in the picture. It won't move. Any suggestions? -
Success, and failure. Balance is back together. I need to adjust the position though as the roller jewel is way of. More than that though, rookie mistake. I set the hair spring between the pins, forgetting that to rotating pin is oval. So when I close it up the hair spring is in contact with the outer regulator pin. I assume that's bad. At rest, without the outer pin rotated closed, it sits like this. Edit... I've been reading and I now understand how the gap should be between the spring and the pins. I'll have another attempt at this. Oh, and the pivots look like this. It's not a banana, it's just because of multiple lenses and trying to get a high mag photo Slightly wonky jewel But, the free oscillation test, 180 degrees, USSR makes that 53 seconds -
Welcome the the forum. Are you talking about the part of the stem that fits to the crown? Photos would help. -

Thank you for the warm welcome. Cleaning stakes is probably 80% of what I do daily 😳. I had issues with severe flash rust with other things and I haven’t tried my ultrasonic cleaner with stakes yet. I probably will now just to see how it works out. I probably have 3-4 thousand stakes at the moment and was looking for a way to clean/polish large amounts at one time. I started out using Evap O Rust soaks, which worked but still required hand polishing and severe flash rust usually happened fast. I found a website that polishes jewelry in a vibratory type polisher so I picked up a large one to try out. (Eventually got a smaller one also). I started out with a ceramic type media, It did a great job, but I still had to hand polish each and every one and it left them like a muddy mess and clogged the ends easily. I then found out the big companies that specialize in polishing small pieces used a stainless steel media to clean and polish at the same time. Evidently using this method somehow burnished the stakes and prevented them from rusting easily. To get an even nicer finish they used a wet polish method and that has been the key to getting my best finish with large amounts of stakes. It just basically removes any rust and corrosion and leaves a very nice finish. I can’t measure any loss of material with a micrometer or a digital dial caliper. Some of these stakes are from the early 1900’s and are not as durable as the newer stakes, so it varies some. I have piles of damaged stakes that won’t make the cut but I’m saving in case I ever get a lathe 😂. I did notice that sometimes the holes were clogged up and still needed to clean them manually. I wonder if the Ultrasonic process would fix that ? Before I ship a set I still manually go through each and every stake but sometimes I slip up and miss one or two. My processes are getting better and I’m getting more organized as I go. Thanks for sharing your process. I have some Boley stuff also that I am hoping to finish up one day. Thank you very much for the welcome and I hope to visit your country one day ! As a side note, we have 2 of your countrymen that have been living with us the last couple of years off an on while they study and play football at the local university , they are teammates of our sons “Soccer” team and we have really enjoyed hosting them and learning about 🏴. Every time they go home for a visit they bring us lots of sweets, chocolates and gifts from their parents when they return . They are exceptional young men and great ambassadors.
