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...
