Omega 620

I purchased this movement some weeks ago and it wants to run. I haven't yet done anything with it because I keep fouling things up with washing the balance and destroying the hairsprings. I'm also still shooting screws all over the place but the new tweezers I got seem to be better (or maybe it's just me)? Anyway, I also got a macro filter to get me somewhat closer than my 100M28 macro lens. This is a focus merge stack of 12 exposures. I see some distortion around the text on the bridge and wonder if instead of 12 shots if I had made smaller focus adjustments and merged 48 instead. Will need to experiment. Also (as noted elsewhere) I pulled the trigger on a trinocular AmScope 7x - 45x boom stand microscope. The scope ought to allow me to drop one of my cameras into the third tube.

Well done! I like this shot!

Thanks, it was really just a quick excuse to try the Raynox 250 (that arrived today) on the 100M28. What I really need is a ring light. While the 100M28 allows me significantly more room between the fully extended lens and the subject, I have only been using a rectangular array of 160 LED's mounted on a small tripod - certainly not optimum.

The other thing that I always forget is to clean my subject. There have been shots that I've meticulously "spotted" in post but this is just too dusty. I should have cleaned it.

The most important thing is practise. One has to learn controlling the force applied by the fingers. Better to drop a screw than to shoot it away. I grip the screws on the threads only to be safe.

What is wrong with lifting a screw with rodico. Not illegal is it? 

I used to do it all the time when i started, i just prefer bent tweezers now for practice.  Occasionally some rodico would get stuck in the screw slot but thats no great shake is it, unless the watch repair police get wind of it.

You just need to address and dress the inside of your tweezers G. And dont grip the screw so hard, it opens up the very tip of your tweezer and pings the screw away.

You wont lose it so easy that way. I do prefer the screw head tbh, it helps me position the screw better. I can orientate the screw to vertical that way by nudging the side of the movement or the movement holder with the screw thread and then drop the screw straight in the hole. I find bent tweezers really nice to use for this. But we are all different its whatever works for each of us. Different methods to achieve the same result, i cant change the way i do things if i wanted to. Been using tools since i was 3 and everyday almost for the last 40 years.

Good tweezers really make a difference. Cheap ones have too much tension so you have to use too much pressure and loose sensitivity.

This is very true anilv. I adjusted a couple of cheap ones when I started repairing. Spent a good hour taking the thickness out of the back ends of them. Made a big difference to the feel, but then acquired a couple of full sets of Dumont and a few others from a job lot sale. These are far superior to the cheapos that I was using.

I can't blame the tools. The ones I have are Dumont, Bergeon and Horotec.

I'm going to say: "It has to be me"

It probably is you G, but you just need to practice mate. Don't let it bother you, you will get better honestly. What specifically are you having trouble with ? Pin down the exact issue then work on that. I've strength trained for 15 years and did body building and martial arts on and off during that time.  Researched and studied endlessly how muscle fibres, tendons and ligaments all work in synergy. Understand how our motor skills adapt and learn to cope and compensate for different situations. That process is less adaptive as we get older we have to accept that that is a part of aging. But I've trained with men and women in their mid seventies and it blows my mind what they were capable of, age is just a number, accept that number is never going to go backwards but  not that it is going to hold you back. Believe that you can do much more than you think you can. Just practice G everyday with a good pair of tweezers, choose the set you are most comfortable with now and stick to that set, don't chop and change because that will disrupt your fine motor skills learning. Our motor learning takes on a similar path to our muscle memory ( we never forget to ride a bike, bit rusty to start with but we quickly improve ). It takes around 300 repetitions to get a form down, if those repetitions are of a crap form because they were rushed or we weren't concentrating on making them good to start with then we've got stuck with a bad habit. It then takes another approx 5000 repetitions to correct that form and make it work the way we want it to. Basically to save a shit load of time get it right first time. This applies massively to bodybuilding as an extreme of our physical abilities but it also applies right down to our finest motor skills. I think what you might be experiencing G is the bad habit of gripping your tweezers too hard in an attempt not to drop anything, unfortunately this has the effect of pinging tiny parts away. Do what I suggested a little while ago, slightly roughen the inside surface of your tweezers to give them a little surface friction, ask me what or how to use or do it if you are unsure. Then just practice everyday for half an hour picking up different sized screws, twist and turn your tweezers while holding the screw adjusting your grip to stop you dropping the screw. Keep your touch very light, never overgripping as this will pull you back into that bad habit that you are trying to get out of, it's far better to drop the screw in front of you than it is to ping it off into oblivion . It will take a little time G so don't get frustrated if it isn't working overnight but it will come and you will become really good at holding screws and springs etc without dropping them or shooting them off. 😊😊

    • Its 4 o'clock in the morning here in the Uk, i cant sleep, i dont sleep, not much ever really. My brain never shuts off to rest, I'm just a constant thinker, i have to be very tired to be able to sleep,  i guess eventually it will be my undoing and my health will suffer because of it I'm sure. But while I'm here i want to get as much out of life as i can, and give as much as i can, to help,maybe to make a difference to someone's life if that is within my capability,recent events have made that need even more clear to me. I'm not sure where I'm going with this or why i bring it up , or if its relevant to want i want to talk about its just in my head right now. What i do want to talk about is something thats been on my mind for ages. I like to be prepared,  I'm not fond of surprises because surprises take control away and i am a bit of a control freak at times. This forum, Our Forum if i can call it that, is here because of two reasons. The guy that created it and keeps it funded and the people that joined it.  Without either, it would not exist, and lets face it one day it won't ( I'm a realist and i talk about things others dont or who are afraid to in other words folk that dont particularly prepare for the inevitable). How many of us visit here regularly ?  How many among us almost depend on the forum as a way of socialising because they are stuck at home and how many of us has it become part of a daily routine to check in and see if they can offer advice or get help with something they are working on or just to have a chat and engage in some banter. The members here are in the thousands and thousands have disappeared over the years many had just a fleeting visit. But there are a good few of us that know each other quite well and visit regularly. I dont know about you but i wouldnt want to lose that communication with you all, in all honesty it has become an important part of that side of my life and helps to feed my passion for all things watches. Some of you may think differently and thats ok, some of may stop and think # what would i do " Without Our Forum " # 
    • Naptha appears to be a general name and its content can be varied depending upon what it's specific use is. Lighter fluid as an example can be light or heavier also with other ingredients to help it burn. Try sesrching for benzine ( as opposed to benzene which is linked to causing health issues ) . There are other fluids such as ethanol that you could try and also methylated sprirts, mostly ethanol with a small percentage of methanol added. Experiment with any new chemical to see how quickly schellac dissolves in its presence. I have tried a few things but hexane is not one of them, i understand it does evaporate very quickly.  Be sure sure to check out any safety data on chemicals you try. Toxicity of fumes and flash point information, ultrasonic machines can heat up fluids even without a heater function. And of course always ask here for personal opinions when trying a new substance. 
    • I have that set and really like it. I prefer that crystal holder over the one that came with my Bergeon claw tool and any time I use the claw I use this one instead of the Bergeon one, just an additional bonus with this tool.
    • Is the Roamer not a split stem? I'm confused on your how your case is put together. If it is a front loader where is it you are putting the case screws? I love me some Roamer, do you have any photos?
    • Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!
