Stereo Microscope

Recommended Posts

I'm considering getting a stereo microscope, around the £400-£500 mark. Someones recommended this one to me

Ebay item  191085725004

which I've almost brought a couple of times this week, but can anyone give me an alternative recommendation.Also having never actually used one (which is probably the reason I've hesitated on buying it) do they make life easier, are they easy to get to grips with?

Hi Lee,

That looks like a nice piece of kit, albeit somewhat over specified.

I have been using a Wild Heergrugg M5 now for about 4 years courtesy of an amazing car boot sale find and I wouldn't be without it. For me the advantages are a much better view of proceedings (obviously) and a much more comfortable working position as it allows a more upright seating stance, not so hunched up. Proper stereo is important for judging distance.

My setup gives me 6, 12, 25, & 50 times mag as standard but it came with an attachment which allows control over depth of focus and increases mag by a factor of 1.25. I use 6 & 12 for most stuff, 25 for hair spring work, and 50 for inspecting jewels and pivots. More than that is of little or no use. One very important factor is working distance (how much room between the watch and the object lens when in focus) as you have to be able to get your tools in there. Mine varies from 12-15cm if I remember rightly which is fine. The one you're looking at states 10cm but that may well change with different magnification, and if that is the max then it's worth asking exactly how it changes as this may well restrict its usefulness. One other word of warning; cleanliness takes on a whole new meaning under 50x mag. Be prepared to get a bit obsessive about it (not a bad thing in a watchmaker).

It's quite a lot of money to shell out though so worth asking about the working distance. And if restricting the mag to 50 - 75x saves money then that's worth considering as you won't miss the higher mag in practice.

Have fun.

to be honest I haven't the faintest idea what I need. the one I linked was one another watch repairer has & he sent me the link. the specs are boggling I assume I need a zoom version for ease? & I like taking images of things I do to (currently use a USB microscope & a camera.)

Im looking for a stereo microscope myself. The only problem this microscope needs to be ordered from germany. I understand an adaptor is available to increase the working distance to 100mm from actual lens to subject. Rememeber also cheap zooms equals poor quality...better with fixed focal length. A microscope would definitely make life easier. There are others options which you can order from within the uk. Let me know your decision.

I got my Inspection style microscope from Brunel Microscopes ~ £180

 

http://www.brunelmicroscopes.co.uk/longarm.html it's excellent and having a longer focal length gives plenty of room for tools. I also bought a USB eyepiece camera to take watch movement photograph's

That looks a good option Odyseus. What like is the image viewing quality with the lens supplied...is their diopter adjustment.

I did look at that one Odyseus which is why I asked the question "I assume I need the zoom version" because I liked the price of the Brunel one, but thought the eBay one seemed to have more spec.

I just got the standard version but I also bought lower power eyepieces too (x10 is standard and I also bought some X5 eyepieces). The microscope comes with three objectives and I use the lowest power one.

It really is an excellent microscope for working on watches !!

Unfortunately it's my experience that it just isn't possible to have all that you need in this game. There will always be another gadget, widget, or tool that you just can't do without. Or is that just me?

These stereo arm microscopes are a lot easier to use and work with than loupes IMHO :)

Yes the BM1 doesn't have variable zoom. ( you have to change the objectives ) but mine is always set for minimum zoom and that's perfect for working on watch mechanisms. !!

If you look on my blog, you see some photo's taken with USB microscope eyepiece CAM !!

I hope you're getting commission for selling these? I too have been thinking about one for quite a while now.

This watch business fair gets a grip o' ye!

What is the distance between the centre of the vertical column and the centre axis of the objective lens when the extension arm is straight?

    • Looks like a fun project. I suspect there is little that would stop it passing modern electrical safety standards, so long as it is earthed, has the correct rated fuse, and a suitable mains cable attached. How does the speed controller work? Some of these old speed controllers use an interesting arrangement of compressible carbon disks as a variable resistor. I have an old Singer sewing machine that uses this arrangement, and a slightly newer Kenwood Chef mixer that uses a triac speed controller. Both are 1970s vintage, and both work well. I would inspect any capacitors associated with the motor assuming there are any, and perhaps replace those with modern suitably rated ones, but the rest I would suspect is fine. If the motor runs, then it will probably keep running. If this is a brushed motor, you might like to take the opportunity to clean the commutator with a bristle brush (not a steel wire one) and inspect the motor carbon brushes too. If the brushes are badly worn or damaged, they can kill the commutator pretty quickly.
    • When working with small metal parts, (not necessarily watch parts, but this applies with those too), I will superglue the part to something I can easily hold, for example plastic card stock, or some other metal, then file away, drill, etc.  then dissolve the superglue in acetone to remove the part.
    • A bit of a classic Timex. So much so that Timex recently released a Snoopy version of the new Miyota automatic based Marlins, and a bunch of other self homages in the Peanuts Charlie Brown, Snoopy & Friends range. This more petite version, I'm guessing from the mid seventies, is the one I remember from my childhood, blue dial and all. It is heading in my direction as a "non runner" (no surprises there), and I was the only bid at £1.93  
    • I have recently purchased a National, Electric Watch Cleaning Machine. Attached is a photo for reference and identification of the model type. As can be seen, it has a fairly typical design, reminiscent of many other types, particularly Elma Super Elite. In fact, I do wonder which came first - the National or the Elma. My musings on this point later. This is a very old machine, circa late 1940’s, 1950’s, but they seem to turn up sometimes on eBay, in various conditions ranging from the “beyond hope” and only really suitable as a donor for parts, and the “old but serviceable” and might-be-worth-a-punt-on machines. This one fell into the middle somewhere, as it was a bit tatty and the heating element did not work. On the plus side, it had all its original cleaning fluid jars and lids, and the motor and speed control gave smooth, controllable spinning and no play in the bearings. I went to visit the seller to inspect it and we did a deal on the spot. This is not always possible on eBay, but as the seller had listed it as for collection only (due to its weight), it was a possibility on this occasion. Once I had it home and gave it the once over, I decided that I would have to either do without heating for the drying stage, or find a replacement element. At the same time, it was very obvious that all of the original cabling was not safe to leave in place and it would all have to be removed and replaced. Any other electrical parts deemed unsafe would also be replaced as I inspected them. So - the idea of a restoration (of sorts) was born. Now - it is not my intention to restore it to the point where it could pass current electrical safety standards, but I will be making it as safe as possible, without losing any of the essential character of the original machine. This is not going to be for resale, so being safe to use is an acceptable compromise, in my opinion. I will however, perform testing on it once the electrical work is done, to make sure that the essential aspects of earth leakage, earth bonds and polarity etc. are passed. (PAT Testing included.) Whilst this is not likely to turn into another example of a superb restoration of an Elma Super Elite (as seen elsewhere on these forums), I hope at least to have at the end of it, a perfectly serviceable watch cleaning machine, and a restoration story - of sorts - of a vintage piece of English watch making and servicing machinery. So first off - the before pictures. This one is a good view of the machine and its cosmetic condition, as purchased. The base is a heavy, cast alloy jobbie, with its original crackle paint job beginning to flake away in places, where the years of cleaning chemicals have attacked it,  but generally sound. The jars still had residues of cleaning and rinse chemicals present. The first wash jar (front left), was particularly grotty and can’t have been cleaned for years. Fairly ironic not to clean the thing, that cleans the things! Maybe it was just left unused and unloved for many years. The mains cable was a cloth-bound type I have not seen in years and could well have been original as it still had the old UK wiring standard colours of red/black/green. Also adding to the vintage-ness, was a very old, Bakelite three pin plug. This must have been one of the first of its type as I have not seen one in brown Bakelite before! (And I am 62...) Anyway, that’s enough for now, as I’m not even sure anyone wants to read much about such an old machine. If anyone is interested though, please add comments and I’ll add to the story as I make progress. At the very least, I hope I have found a potential solution to finding/ making your own heating elements for these old machines, which could also include providing replacements for Elma Super Elite, RM80/90 HCS511 etc. Machines. More details later...
    • Wood is surely more sustainable and cheap than brass... I noticed that sometimes people like clickspring (makes videos on tooling and clockmaking) use some kind of superglue to hold metal together.  At 6:54, if you get bored...
