But sometimes the arbor does not fit the mainspring for the correct size barrel and/or the other way round so it is useful to have a set - but even my set with 17 barrels both left and right hand cranks will not fit every mainspring/barrel combination, but the more sizes you have, the more chance you will have that you will have a correct combination.

    • That is the Indian copy of an MKS 46610 (famous Japanese brand), I got one as clearance from Germany and paid maybe less than that. If you use the search function you should find my posting.
    • My experience with the handheld cheap Chinese glass presses on eBay is truly poor, and I've come to learn that I'm not alone. Yesterday I was struggling with it for over 30 minutes to fit an armoured glass in a Vostok Amphibian before giving up. At that point, while still holding it in my hand looking at it with disdain, I thought: "What a piece of utter rubbish!". Anyway, what I'd really want would be a Robus press, but gosh, that would be over £500 with the die set (tax included, excluding shipping)! So, I found this tool "Professional spindle press for housings and glasses with twenty-four inserts" on eBay for £72. It sure sounds promising, but it would be great with a review, or if none can be had your opinion.
    • Sharpening is a science and an industry. Trivia facts follow An important figure in drill sharpening is Joseph Mazoff, a self-taught American. His article is still current on the matter and the basis for most sharpeners, I have attached it here.  A 1st brand drill bit sharpener can cost €600  https://www.wabeco-remscheid.de/catalog/product/view/id/6710/s/spiralbohrer-schleifmaschine/category/487/  It's Chinese copy, one half of that https://www.aliexpress.com/item/Drill-Bit-Electric-Big-Grinder-MR-13A-CNC-drilling-cutter-grinding-machines-with-ER11-collects/32867482062.html If you have something that cuts there is a professional way to sharpen it. Blunt axe? No problem https://www.sharpening.org.uk/product/tormek-sva-170-axe-grinding-jig/ I'm currently disputing an Amazon seller that sent a cheap knife sharpener instead of a 75mm grinding wheel  Drill_Point_Geometry_nt.pdf
    • I recall a fairly recent topic which where some was saying that Bergeon screwdriver had become worse and worse with time. We got the proof here. 
    • A relic of the Jewel Wars, this 35mm 1950s Mount Royal with an 80 jewels (kind of) Felsa 4002, 21 of which are broadly functional and 59 which, er, aren’t. I’ve no idea how many of these watches survive today or, indeed, were ever made but it “coulda been a contender” until the likes of Waltham, Orient, and Titoni climbed into the ring with their 100 (and more) jewelled efforts. Of the two recorded makers of a Mount Royal brand, Choisi seems to be the most likely candidate for today’s curiosity, it being a product of the original company founded in 1929 before its demise, date unknown. The company name was seemingly reactivated in 2013 by a Singapore-owned  enterprise which, from what I can see, is largely producing retro-style watches along with homages based on the old company’s vintage models.  Regards.
