      I'm not sure of the internal diameter of yours, not having used Imperial spools before, but some of the cheap plastic "Universal Spools" have removeable plastic cores that may allow you to pop them out and be compatible with your machine. The one's I've got have a 3/4" or 19mm diameter hole and are meant to be used with Remington machines instead of their metal spool hubs. (Example: https://www.amazon.com/Universal-Typewriter-Typewriters-Replacement-Compatible/dp/B0D9P2P2Q7/?th=1)

    1. Congratulations. You've joined an exclusive club that includes writers like: Edward Abbey John Ashbery, Saul Below, Johnny Carson, Joan Didion, Bernard Kalb, Elia Kazan, Helen Keller, Grace Metalious, Arthur Miller, Carl Reiner, Fred Rogers, Rod Sterling, George Sheehan, and Wallace Stegner.

      I've got over 60 typewriters in my collection and the KMG is my favorite, especially when it's clean and properly adjusted. I've got one each in Royal Elite and Royal Pica typefaces they're so nice.

      KMG controls diagram: https://site.xavier.edu/polt/typewriters/RoyalKMGdiagram.jpg<br /> Richard Polt's site doesn't have a manual (yet) for the KMG, so pull the manual for the Royal KMM instead. It was the model made just before the KMG and should be functionally identical. The Royal HH which followed it was also broadly similar. https://site.xavier.edu/polt/typewriters/tw-manuals.html

      The spools for the standard Royal typewriters (Ten, H, KH, KHM, KMM, KMG, RP, HH, FP, Empress, 440, 660, etc.) have a custom metal mechanism for their auto-reverse. The spools are known as the T1 (which is the same as General Ribbon part # T1-77B , T1-77BR, and Nu-Kote B64.) If winding on universal 1/2 inch wide ribbon onto them, remove any eyeletes which aren't needed and may interfere with the auto reverse. https://www.youtube.com/watch?v=TMDfGkKqbgE

      Incidentally when browsing YouTube for repair videos, the mechanics of all the Royal standards (listed above) are all incredibly similar if not exactly the same, so search beyond KMG to find solutions.

Don't get liquids or water on these as it will seep inside and discolor or damage the paper legends. They're replaceable, but it requires a special tool and/or lots of patience. Incidentally, these were the last US manufactured typewriters with glass keys.

      Rightly or wrongly I'm sure a vanishing number of people at that time would have held your view.

      You've got to remember the historical context of this ad. During World War II all but one typewriter manufacturer in the US ceased production of typewriters and the one remaining was really producing machines for the military. This ad from 1943 actually says in tiny print at the bottom: "Royal is making bullets, and parts for airplane engines, propellers, machine guns, rifles." Civilian groups did drives to collect typewriters to send them to the war effort. Many of the extant and upcoming generation of typewriter repairmen went off to the war effort. All this against the backdrop of people being used to taking their machines (especially office ones in use 8 hours a day) in for service every year or so for cleaning and adjustment. Most office typewriters of the time were in use for an average of 3 years before requiring complete overhauls or replacement. In addition to all of the other things being rationed, typewriters and typewriter service were also being heavily rationed, particularly because the manpower and steel was being diverted heavily to the war effort.

      At the time, most typewriters were in the $125-200 range which is the equivalent to about $1,500 now. They were trying to help people preserve their machines and functionality. This was at a time when almost any sizeable town in the US had at least one repair shop busy with work. A city the size of Chicago probably had several dozens of repair shops working full time and that likely dropped to just a few during the war. (There's only one now, and it's only been open for a few years; it also has a wait list of several months for service because it's so busy.)

      The issue of typewriter preservation was so great during the war that the U.S. Navy produced a series of videos about their proper use and maintenance of them *and other expensive office machines of the time). See videos at https://boffosocko.com/2025/06/06/typewriter-use-and-maintenance-for-beginning-to-intermediate-typists/ The government also got involved in creating maintenance manuals like Basic Typewriter Care and Maintenance, Equipment Maintenance Series No. 1 (US FWIP, 1945) and repair manuals like War Department Technical Manual TM 37-305: Typewriter Maintenance (1944) which is essentially the same as the [1945 Ames manual[(https://site.xavier.edu/polt/typewriters/AmesVol1-Standards.pdf).

      Comparing this with today when the general value of typewriters is almost nil and we're lucky to have a few dozen professional typewriter repair shops still operating, but the rate of retirements and deaths has long been outstripping the replacement rate and you'll understand why self-service is necessary. Even given this, the number of typewriter fora on the internet, Facebook, Reddit, etc. the amount of tinkering knowledge is almost cripplingly bad but seems to chug along. You'll notice that there are an awful lot of people just trying to identify their machines much less carry out the most basic repairs. The number of "broken machines" I've acquired in my collection that only needed the ribbon color selector set to something besides "stencil" is a sad indicator of the state of typewriter knowledge now, much less what it may have been in their heyday, tinkering or not.

      Even by 1983 as typewriters were already beginning to feel the pressure from the computer business, books like Bryan Kravitz and Nancy Gorrell's Hints for a Happy Typewriter were attempting to educate people on proper maintenance and light repair before needing to rely on repair shops that were already starting to feel the pinch.

      Incidentally, IBM wasn't what put most typewriter companies out of business. It was vicious competition caused by offshoring and the cheapening of parts and materials while computers in general did the rest. And as for all those typewriter repair shops: most began selling/servicing word processors, office machines like fax machines, photo copiers, dictaphones, and even computers.

    1. Choosing a Typewriter for Writers<br /> by [[Joe Van Cleave]]

      Manual typewriters for writers with a focus on machines made without needing to tinker/repair them.

      Joe primarily focuses on typewriters he actually has in his personal collection more than other potential great machines. Having been collecting for his particular purpose for a long time, he's got a pretty tight set of good recommendations.

      He's also got some good advice here about how to go about finding a machine and using professional typewriter shops to do so.

      Electric typebar typewriters with more tolerance for poor technique.

    1. Advanced Typing - Shortcuts (1943)

      Advanced Typing: Shortcuts. 16 mm. Vol. MN-1512c. United States Navy Training Film, 1943. https://www.youtube.com/watch?v=JUJfCfqgsX0.

      Correct typing posture: fingers curved<br /> arms sloping up<br /> light fast strokes<br /> steady rhythm

      fast continuous motion of return lever<br /> using backing sheet (aka temping sheet ??)

      Shortcuts:<br /> mise en place for office supplies (she doesn't use this phrasing though) - greater efficiency - cuts down on searching

      tabulators can be helpful. There are two types:<br /> - automatic - handset

      Use tabs for paragraphs, dating letters, columns of numbers, and letter closings.

      To clear all tab stops, put carriage to left, hold tab clear key and move the carriage across. (Usually applies to Royal, Remington, Underwood, and Electromatic).

      On LC Smith and Woodstock machines sometimes have a tab clear lever on the back.

      Decimal tabulator keys help to align a variety of numbers around a decimal point. 09:43

      Always have a few tabs set to prevent a flying carriage which can be hard on the machine.

      When using carbon sheets which are slightly longer than the paper size, cut off a small triangle at the top left hand side. This makes it easier for one to separate the carbons from the copies by holding the top left with one hand and pulling the carbons out from the bottom of the stack.

      To align multiple sheets of paper for carbon copies, use a folded sheet at the top to taco the pages into the machine. Remove the folded sheet once the carbon pack is rolled forward.

      Paper bail rollers should be set to split the pages into thirds (for two rollers).

      Remington noiseless machines have a pressure indicator on the front of the machine (usually above the keyboard) which can be used when using thick carbon packs that may cause the ribbon guide to stick or bind.

      Only erase when the carriage is fully left or right to prevent eraser crumbs from falling into the machine. 15:26

      Use a soft eraser on carbon copies. Use and insert slips of paper behind the carbons and allowing them to stick out the sides, erasing from back sheet to front so as not to allow the eraser to mark your carbon copies. For the front sheet, use a shield and ink eraser and erase with a horizontal motion. After erasing, easily pull out the inserted sheets.

      When typing a correction, tap the key lightly two or three times rather than hard once.

      When in a rush and it's necessary to add a word (on double spacing), underline the last letter of the prior word and type a slash (/). Then move the typing line up and type the insertion above the prior line. This creates an "arrow" of sorts for the inserted word.

      Details for inserting extra letters in misspelled words using half-spacing machines. (Underwoods and Electromatics don't have this function.)

      Light pencil marks at the bottom of the sheet can help to indicate the coming bottom of the sheet.

      Putting up the card holders (fingers) on Underwoods and Royals. They help to hold the card and improve print quality and reduce noise.

      Card holders can cause markings on carbon packs if they're not lowered.

      Trick for quickly writing postcards in succession: Disengage the ratchet using the platen spring release (or variable platen switch) Type the address on the front of the card. When done give the platen a quick practiced spin. The postcard with "jump" up and stop at the paper table and be in position for rolling in the opposite direction to write the message on the back of the card! When done a faster spin of the platen will shoot the card over the back of the typewriter where it can land in a box to collect all the postcards which were written in such a manner. <br /> timestamp 23:22

      Time saving methods for addressing envelopes:

      • Front seat principle. Insert the envelope in the usual way and type out the address. When done, turn the envelope down through the machine with the right hand. With the left hand, place the next envelope between the top of the first envelope and the front of the platen. Feed the first envelope back through the machine (in reverse) and the second will be rolled in to place for typing. Continue in this fashion until finished. All the finished envelopes will stack up in the back at the paper table.

      • Chain feeding. The first envelope is inserted and rolled partway into the machine. A second envelope is inserted between the platen and the second envelope (behind the platen). Turn the first envelope to the writing line and type the address. Take out the first envelope and insert the next the same way as before.

      • Uses paper bail. Do the first envelope in the usual way. Spin it out of the machine up and behind the paper bail into a box behind the typewriter.

      For quickly doing labels or small cards:<br /> Create a small zig-zag fold into a piece of paper to create a pocket slot which can be scotch taped on either side. This template paper can then be inserted so that the pocket is visible above the writing line, but the paper below it is still in the platen. The label or card can be placed into the pocket and the platen reversed to feed the label or card in backwards to the desired typing line. Using a v-groove or hole in the typing line can create a pencil line to serve as a guide for inserting many labels at the same place so that the typing lines up between labels.

      Some offices had special platens for holding cards like this.

      Pockets like this can also be used to hold the page to add additional lines at the bottom of pages. Deeper pockets may need to be used for doing this with carbon packs whose carbons are longer than the pages.

      Alternately one can do something similar by creating a inverted u-shaped set of slits into an index card. to hold such labels.

      When in the midst of a page and needing to do another piece urgently, roll back the letter until about 2 inches from the top, and then place in the new page and one between each of the carbons. Then roll forward to do the short message as necessary. Turn back to the insertion position to remove the copies and then continue with the first letter where you left off.

      For drawing horizontal lines on typewriter paper, push the carriage to the extreme left and place the pencil or pen at the edge of the card guide and the scale. Then move the carriage to the right to effect the line. For vertical lines, put the carriage at the desired space and place the pencil at the card guide and scale and move the platen up/down as necessary.

    1. Your IPA is temporarily liquifying the oil and grime, but as it evaporates near room temperature pretty quickly (as do other degreasers like mineral spirits, paint thinner, lacquer thinner, naphtha, etc.), it disappears and leaves the oil and grime behind.

      While you're flushing it out, be sure to move the typebars back and forth to help flush the grime out of the segment as you add more IPA (or other degreaser). If you have it available, it's also helpful to loosen things up with a degreaser and follow it up immediately with compressed air to blow out all the grime.

      It may take several rounds of flushing and air to completely free up your typebars. Things aren't really clean until they're dry and move freely.

    1. reply to u/UsefulLength9143 at https://old.reddit.com/r/typewriters/comments/1ruew5h/royal_p_this_isnt_pics_font_is_it/

      Looking closely at the slugs with letters, several clearly have a "P" foundry mark which was commonly used in this time period to identify Royal's "Royal Pica" face (see: https://typecast.munk.org/2011/04/24/1964-nomda-blue-book-royal-font-styles/) which was the generic name they gave in their catalogs to this particular pica (pitch) typeface. Similarly a foundry mark of "E" was often used to represent their 12 pitch "Royal Elite" typeface. Surely it's the case that the designer had some other name for this typeface, but I've never seen Royal documents which specify anything other than Royal Pica or Royal Elite.

      While it certainly helps to see the rulers on the carriage to doublecheck, one can guess the exact typeface in this instance solely by the foundry marks, though this is not always the case for a wide number of manufacturers.

      Generally people are right in asking to see the ruler as the difference in width of slug on a 10CPI and 12CPI machine is on the order of 1/64 of an inch which is incredibly hard to discern visually on photos like these without something to use for scale.

    1. reply to u/Ripraz at tk

      I analogize typewriters to cars: there really isn't a "beginner friendly" option, they're all just cars or typewriters. This being said, how well built and engineered they are and some of the smaller optional features or "trim lines" can differ a fair amount. With typewriters, one of the biggest trim differences is the tabulator (does it have one and how do the controls work? If you're a screen writer, you really want one, but if you're doing other general writing, you can get away without one typically.)

      With Olivetti, you're probably going to find peak typewriter manufacturing and materials from the 1930s into the early 1970s. The best stuff is likely in the 50s and 60s where their design chops are also the strongest. Their stuff in the mid-70s and after becomes more plastic and isn't as solid (eg. Lettera 35).

      Some suggestions: <br /> Standards: Graphica, Linea 88<br /> Portables: Studio 42, 44, 45; Lettera 22, Lettera 32

      Be sure to take a peek at the individual typewriter galleries and individual machines in the database to see the shifts in design over time, if that interests you.

    1. Reply to u/croceldon at https://reddit.com/r/typewriters/comments/1rsq69i/dust_cover_recommendations/

      I use a lot of index cards, so I often just cover the opening in the hood with one and clamp it down with the paper bale. The rest I can just dust off with a painter's "chip brush" I got at the hardware store for $1.50.

      I also use a handful of microfiber cloths I got at the dollar store for $1 each and throw them over the carriages of other machines. They also double for mopping up flop sweat during marathon 8 hour writing/typing sprees if you need them for that.

      The only way I'd come close to dropping $80 bones on a typewriter cover is if they were as finely crafted as some of the ones I've seen our collector friend Tom Hanks using: https://boffosocko.com/2025/06/16/tom-hanks-ingenious-custom-typewriter-covers-mats/

    1. it is not mold; it is plasticizers coming out of the plastic. I remove it with various means: alcohol, polishing with a very fine polish, Goo Gone™, naptha, and such.

      The white gunky substances seen on the plastic keys of old, unmaintained typewriters generally isn't mold, but plasticizers coming out of the plastic. These can usually be cleaned off using simple household cleaning products or if necessary heavier cleaners (Goo Gone, alcohol, naptha, etc. - test these on hidden parts first to ensure they don't react with or destroy the plastic or remove the paint of the key letters) followed up by light waxes or polishes and buffing.

    1. reply to u/KingCollectA at https://reddit.com/r/typewriters/comments/1rpr1ha/got_quite_lucky_finding_a_free_olympia_sg1_had_to/

      Typically the SG1 has at least 3 serial numbers. Two matching ones on the main body (one hiding deep inside), and the third on the bottom portion of the carriage, which may or may not match the other two. (The carriages were meant to be easily swappable for machines with the same CPI/escapement sizes.) Removing the carriage will usually reveal the body serial number (typically a 7-XXXXXXXXX) format which you can compare with the grid of serial number ranges to see where yours fits in at https://typewriterdatabase.com/olympia.61.typewriter-serial-number-database.

      I just got mine and have finished most of its servicing, though one or two small adjustments remain for it to be where I want it to be. Beyond this, it's been spectacular. See also: https://boffosocko.com/tag/Olympia-sg1/

      How are you defining "use it for entertainment"? <br /> - Having a zettelkasten for tracking knowledge/information in the entertainment business? (Yes, this is possible, I use it for this regularly.)<br /> - Using it for tracking the television, movies, and other past times and hobbies? (Yes, definitely a thing. I have tranches of cards for all these things.)<br /> - Using it as a daily diversion to entertain yourself in general? (Yes, loads of us find the system interesting and entertaining on a regular basis. I suspect that if we didn't we would give it up entirely.)<br /> - Perhaps you had some other definition of entertainment, I didn't cover?

      Hi All, In a fit overconfidence a couple of years ago, I bought a brother Deluxe 220 typewriter which worked fine other than being sticky. I duly tore it down, cleaned it up, oiled it, put it back together and... watched as nothing happened because somehow all of the springs had fallen out and were now sitting on my workbench. I then put it on a shelf and forgot about it, until starting a clearout last week. I would be deeply indebted to you if anyone who has this typewriter (or one of its sister models, as I understand it most of the JP-1 models are the same) take either some photos or a good video of exactly where all of the springs inside it connect to?

      To help remove a stripped screw head, hit it with Kroil or a similar penetrant first. Then with a screwdriver, punch or similar tool, give it purchase on the right hand side somewhere and give it a nice whack with a hammer. This should turn the screw enough to move things along.

      Rules of Good Repair Practices:<br /> The Success of the repair depends upon the Rapairman's ability in following the rules of good repair practices. These rules can be summed up as follows:

      1. Read the Service Bulletin thoroughly.
      2. Know what you are looking for. Never guess. Always investigate the source of trouble. Ask, if you do not know.
      3. Determine troubles by the process of elimination.
      4. Every part, no matter how small, has a job to perform. Do not overlook the smallest detail.
      5. Use the proper tool. Keep tools in efficient working order.
      6. Carefully handle smooth, plated or bakelite parts to prevent damaging or scratching.
      7. Make the repair like you would want it, if you were the customer.

Then repeated with an upper case "H". The marks were just a tad over 7.5 mm apart checking with a rule. No precision of course but close.

      The number printed on the ring in the basket of Olympia typewriters, just above and to the left of the word "De Luxe" is the distance from the baseline of the bottom slug character to the baseline of the top slug character.

      In many instances it will be 7.6. I'm curious what other typefaces show and if this thesis holds?

    1. Nakajima All (中島オール) went bankrupt back in 2019. (Not to be confused with the Nakajima Aircraft Company.) https://www.nikkei.com/article/DGXMZO41025530X00C19A2X12000/ https://newswitch.jp/p/17807 Archive of the now-defunct website:(https://web.archive.org/web/20180816074211/http://www.nakajima-all.co.jp/) Someone might've bought the equipment from the Nakajima All factory in Indonesia and is still pumping out new ones (since the electronic typewriters Swintec sells are rebadged Nakajima All ones), but I'm not completely sure.

    1. On an SG1 and an SG3 here, the right margin stop locks the printing keys as expected at x characters after the bell but not the spacebar nor tab, which both ring the bell and then blow right past the margin stop. Additionally, when the End-Of-Line lock stops the printing keys, I can continue spacing past the margin and then after about three spaces on the SG1 and about eight on the SG3 the printing keys are again active.

    1. Although the 'Mazac' tab. brake shoe problem is common, I cannot say that I have seen this before on an SG1 margin.  Interestingly, there is a similar 'exploding Mazac' problem on the ribbon reverse arm of the Olympia Model 8 post-war.  The factory probably had no idea at the time that this 'easy to die cast' metal would do this in years to come.

      re: cracking house on tab sets for SG1<br />

    2. the disintegrating tab. brake shoes !  I have seen this on SM portables too - they have the same tab. brake.  As a temporary measure, you could try filing the worst of the expansion off and re-fitting.  You can also sometimes get away with having just three brake shoes instead of four.

    1. [rant] As a side note, I'm wondering if this is an example of how the internet, social media, and self-publishing has contorted our designation of authoritative sources.For example, the only person I consider to be an authority on typewriters in this forum is Tom (thetypewriterman). He is the only one here (to my knowledge) who has actually been trained as a typewriter technician and has worked in the trade - long before the current crop of self-made authorities 'discovered' typewriters. Tom was actually repairing machines while some of us were still using them for school or work prior to the introduction of the personal computer.The majority of our forum members might be very experienced, some are self-learned shade tree mechanics, but to my archaic way of thinking this doesn't make someone an authority on the subject.I apologize for this obvious and distracting tangent. This is a sensitive subject for me because my own trade has been overrun by internet created, so-called experts who lack any formal training or professional experience. I throw up in mouth a little when I read, or hear the word influencer; the digital generation allows itself to be lead by those who talk the loudest, run the fanciest websites, or have the greater number of social media followers. No one seems to care if those influencers have any credentials that would validate their public opinions.These observations are not meant to slight dragon typer. I don't know who the OP's authority is, nor do I need to; however, I did cringe at the "typewriter god" description and have to wonder if this god is someone who actually worked in the typewriter industry, or is just an enthusiast like most of us here who became an influencer by way of self-promotion.

    1. Olympia SG1 1953-72 cleaning (technical restoration)

      Partial/very modest teardown and cleaning of an Olympia SG1. Only beginner level. No flush of machine or real blow out.

      Interestingly he uses a steel brush to get rid of the brown adhesive where the felt used to be, but doesn't replace it.

      Also demonstration of cleaning corrosion off of screw heads with steel brush on a vice.

      Carriage work starts at 06:17. He opens it up and then gives up after a modest wipe down. He does show some

      Uses a toothpick to oil the joints, but only shows a modest portion of the process.

    1. I'm at eleven typewriters now, with ten in working order and one that is a toy. I gave two machines away for free, and I sold one to a workmate for the same amount of money that I spent on it. My intentions to acquire and keep them changed through the three years of me being into typewriters. It started with finding a broken SG1 in the trash at the side of the street that I was able to repair. Then I was looking for a use for it, because it had found a place in my heart. I found two other machines in working order, also in the trash at the side of the street, of which I am keeping one and I have one away because it wasn't my liking. I received one as a gift from my brother-in-law that was owned by his grandfather, which is a very nice machine that makes it easier to keep for sentimental reasons. Then there is another machine that once belonged to my long-gone grandfather, which I keep for sentimental reasons and its nice techno pica typeface. This list keeps going on. So, there's a mixed bouquet of reasons I make up to keep machines and why I just can't give that specific piece away. I know I'm a hoarder, but the size of the machines keeps me in certain limits. Is it consumerist? Well, yesn't. I must admit, I would love to own a chocolate script Olympia SM3, and yes, I do like to show off my four different typefaces. I am looking to find a sixties SM9 to find out what the fuss is about in comparison to my late seventies SM9. But on the other hand, nothing beats the satisfactory achievement of finishing another three pages letter for one of my daughters. I hope they will read my lines one day and hear their daddy's voice through the paper that I touched before them and the imprints that my muscles caused. It is a piece of me, turned into ink on paper, that remains. And it is some obsolete tech that I curated/used/liked/hoarded, that will probably go into steel recycling after I'm gone.

      THE MAGIC OF BELLE ISLE (Magnolia Pictures, 2012) features an Underwood standard at about the 31 minute mark.

      Morgan Freeman says: "Look at that machine. I like that you have to write a bit slower on a manual. Like the way it sounds. I like the way that the letters bite into the paper. I like that you can feel there's a genuine human being, doing the work."<br /> (doublecheck the exact quote)

    1. The Man Who Stole Infinity<br /> by [[Joseph Howlett]] in Quanta Magazine on 2026-02-25<br /> accessed on 2026-02-26T09:01:10

      Dedekind proved that the set of algebraic numbers is the same size as the set of whole numbers.

      Cantor plagiarized his proof and later went on to prove that the set of real numbers is larger than the set of whole numbers.

    1. Even with keyring pliers and the skill to use them, the blackout paper method is a lengthy one.

      Keyring pliers are used to remove the metal rings off of both circular and tombstone glass typewriter keys so that the legends can be replaced or even covered over with black paper circles for teaching or learning typing. They take some practice and skill to use, but speed up the replacement of legends significantly.

    1. Mineral spirits are perfectly safe for key buttons. It's critical to make sure the solvent you're using really IS true mineral spirits, though.Other solvents, such as those billed as "laquer thinner" are NOT safe for plastics. That includes acetone, xylene, and any solvents containing them. I have heard that Selectric III keys are resistat to laquer thinner, but I still wouldn't use it even on a III. Laquer thinner may be applied VERY carefully after the full mineral-spirits bath using a syringe or small squeeze bottle for specific metal pivot points such as interposer pawls that tend to get extra-stuck from dried-out lubricants.

    1. That's just a post-war one. Rheinmetall typewriter factory was situated in Sömmerda, Thuringia (so far from Rhein), this way it become a soviet-owned company after 1945 and before it was returned to newly created GDR. A lot of these machines were produced to be supplied to USSR as kind of reparations payments. The layout also proves this. Here's an experimental "ЭУКЕН" layout, one of transitional variants on the way to modern "ЙЦУКЕН" (since 1953). While all the pre-war typewriters were built with 1918 layout "Й1УКЕН"
