 Hi  A short while ago there was a mention of re forming and adjusting balance springs. I mentioned I had made some tools from sewing needles with the eye ground down providing a fork with witch to adjust the springs. I used two sizes of needle, put in a pin vise and just stoned the end off. Done carefully they make usefull tools. Mine are just fitted into to old chopsticks and being square they don't roll about the bench.    A sewing machine needle fitted into a handle also gives a good stiff tool for manipulating small parts and inspecting train wheels etc.  These are not expensive to make in either time or materials but I wouldn't be without them.

Great tips . i am going to make a couple of those . I though about this for a while. I often need to fix the balance spring to get it running perfect. I have a 5 mm plastic rod that would work as a handle instead of te chopstick

There are manufactured fork end needles. I see if I can take a magnified picture of one to post.

Sewing machine needles, of course.

Brilliant idea.

 I had thought of using ordinary sewing needles, but sewing machine needles, since they have a flat face ground on them are perfect. I may even fabricate a couple of 3d printed handles so I can slot them right in.  My wife is a quilter, so now I have a use for the old needles when they get dull or break, rather than discarding them.

Something else for the to-do list when I get back.

      Epilame / Fixodrop

      By VWatchie · Posted

      Sounds great! And yes, I would use grease for the keyless as well although treating the parts with epilame would make the grease less likely to spread in the long run. Not critical but won’t hurt. My current strategy is to epilame treat all parts getting in contact with oil or grease.

      Epilame / Fixodrop

      By Knebo · Posted

      Hello everyone, for what it's worth, here is my approach: 1. Escape wheel submerged in Epilame, then dried quickly with a hairdryer. Then the final tip of the pivots are cleaned by poking into pithwood. The logic being that the Epilame is removed at the intended contact point (to avoid any residue that may mix with the oil), but remains in the areas where oil is not supposed to spread to (further down the pivot towards the wheel). The escape wheel teeth also benefit from having Epilame to keep the 9415 in place.  2. I use a syringe to treat only the pallet stones. I suspend the pallet fork with some Rodico so that the stones hang downwards. I notably use a rather thick needle where a drop WON'T form, but rather where the Epilame liquid stays in the needle tip, which I then dip into the pallet stones. It requires some practice to get the right amount of Epilame into the needle tip, but it works for me now. This way, no drop will "jump" onto the pallet fork and potentially go all the way to the pivots.  3. I let the movement run for a few minutes without lubricating the pallet stones... to scrape off the Epilame in the intended contact "channel". Then I remove the balance again and lubricate the exit pallet stone with 3-4 successive drops. See the "channel" that forms on the pallet stone in the picture -- not so easy to see, but it's visible.       I am conflicted about the use of Epliame in balance jewel settings. My impression is that the two jewels sufficiently suspend the oil (even 9010). Apparently Rolex recommends NOT to use Epliame there (heard from a former Rolex service center watchmaker), as it could cause additional wear. Apart from that, I follow specific instructions where I can find them. E.g. the infamous Rolex reverser wheels or sometimes (parts of) the seconds wheel. Exception: I'm currently servicing an Eta 2824 and will probably ignore the service sheet that recommends treating the whole keyless works with Epilame and then using HP1300... I'll skip the Epilame and use 9504 grease.

      I'm going to give this a try today/tomorrow on my UTC33/Seiko 66, thanks!

      Don't forget Mark is a hard working watch maker so he is also tied up with work. I'm sure he is keeping his eye on this forum making sure it is running along nicely.
