Mathematics with Typewriters

What you're suggesting is certainly doable, and was frequently done in it's day, but it isn't the sort of thing you want to subject yourself to while you're doing your Ph.D. (and probably not even if you're doing it as your stress-releiving hobby on the side.)

I several decades of heavy math and engineering experience and really love typewriters. I even have a couple with Greek letters and other basic math glyphs available, but I wouldn't ever bother with typing out any sort of mathematical paper using a typewriter these days.

Unless you're in a VERY specific area that doesn't require more than about 10 symbols, you're highly unlikely to be pleased with the result and it's going to require a huge amount of hand drawn symbols and be a pain to add in the graphs and illustrations. Even if you had a 60's+ Smith-Corona with a full set of math fonts using their Chageable Type functionality, you'd spend far more time trying to typeset your finished product than it would be worth.

You can still find some typewritten textbooks from the 30s and 40s in math and even some typed lecture notes collections into the 1980s and they are all a miserable experience to read. As an example, there's a downloadable copy of Claude Shannon's master's thesis at MIT from 1940, arguably one of the most influential and consequential masters theses ever written, that only uses basic Boolean Algebra and it's just dreadful to read this way: https://dspace.mit.edu/handle/1721.1/11173 (Incidentally, a reasonable high schooler should be able to read and appreciate this thesis today, which shows you just how far things have come since the 1940s.)

If you're heavily enough into math to be doing a Ph.D. you not only should be using TeX/LaTeX, but you'll be much, much, much happier with the output in the long run. It's also a professional skill any mathematician should have.

As a professional aside, while typewriten mathematical texts may seem like a fun and quirky thing to do, there probably isn't an awful lot of audience that would appreciate them. Worse, most professional mathematicians would automatically take a typescript verison as the product of a quack and dismiss it out of hand.

tl;dr in terms of The Godfather: Buy the typewriter, leave the thesis in LaTeX.

Almost every portable and ultra portable typewriter made from the 1930s onward came with a case that the typewriter locked into. On almost all of these the top of the typewriter case was easily removeable from the base with a spring loaded locking mechanism of some sort. This allowed the user to sit in almost any chair and use the typewriter on their lap. The thin case bottoms prevent dirt and oil from soiling one's clothes.

Beginning in the late 60s/early 70s some manufacturers began making plastic tops that clipped onto the typewriter bodies, but often these are more brittle and prone to breaking/shattering due to the type and age of the plastic. (I'm looking at you Remington Streamliners...)

Our cat used to love "hiding" in the wooden case tops of my 1940s and 1950s Smith-Coronas (Clippers, Sterlings, Silents, Silent Supers).

It's really only the larger and much heavier standard machines that didn't come with cases at all.

Buckram is a good choice of material for recovering pre-war black typewriter cases.

TypewriterCellar on Instagram may have some good ideas in this area.

Using an Akona regulator bag from a diving supply store in Hollywood as a replacement case/bag for an ultraportable typewriter.

Adler's have a quirky locking mechanism for helping to lock the machines into their cases and after decades of storage, the rubber can compress thereby locking the typewriter into the case permanently. Removing the e-clips internally will unlock them at which point the rubber compression locks can be replaced.

The article mentions other incidences of this. Another example at https://new.reddit.com/r/typewriters/comments/1fckg8f/removing_triumph_gabriele_1_from_case_base_plate/

On many of the older 40s/50s typewriters, the same key will work on almost everything. If you search online there are a few people who have posted a 3D printable key that you can download and may be able to print at your local library. I'm guessing based on the limited photo, yours is an early 40s Smith-Corona.

I've tried a few local locksmiths who don't seem to carry these keys anymore.

I've got a late 40s Smith-Corona latch that occasionally self-locks and for ages I used a bent paperclip in the rough shape of the old keys to easily pick the lock with just 10 seconds of jiggling around inside. Roughly a 2 mm straight section of paperclip with a 1mm "T" section that sticks out (even just on one side) about 4-5mm and then continues straight ought to work if you're in a jam.

The level of security these keys/locks provide is minimal at best.

If you go the online route to buy a key, they can be quite expensive, so if you're a collector, just wait for a machine that comes with one and you'll have another typewriter for "free" in the deal.

Tools of the typewriter trade by [[Retrotype]]

Excellent overview of many of the basic tools for typewriter repair. Didn't have the strongest grasp of all the tools' specific names, but good enough for describing their general use cases.

Example of a typewriter toolset including a case made for telephone company repair, but which works with typewriters.

• Shore A durometer gauge
• nylon fishing/picture hanging wire spec to 25kg (for drawband replacement)
• thick waxed string/yarn for repairing fishing nets (for drawbands)
• nitrile gloves (to prevent staining, issues with mineral spirits, and other caustic chemicals)
• XPower pressure blower for blowing out dust/dirt and mineral spirits. (smaller than an air compressor)
• nail grooming set with tweezers, picks, etc. (not technically necessary, but sometimes useful)
• dental tools (for use as spring hooks)
• Renaissance micro-crystalline wax (non-corrosive, made for British Museum, good on marble, wood, leather, etc. Good on bare metal for treating previously rusted metal. (It's recommended to use an abrasive polish for improving the shine of glossy paint however)
• Pouch and set of precision screwdrivers (he only uses the flatheads though the set includes other) Prefer hollow ground tips which are squared off rather than wedges.
• Chapman bit set of screwdrivers (with hollow ground tips) He prefers these for hard to remove screws. Issue that it's a bit thicker at the tip.
• Liquid wrench penetrating oil for helping to loosen screws (he likes this better than WD-40)
• brash wire brushes
• steel wire brushes (uses less frequently as they're more abrasive)
• pouch of precision wrenches (imperial and metric) his are bladed, Moody tools wrenches (mfg.) prefer the thinnest tips
• microfiber cloths
• jig for soldering typeslugs on typearms
• pouch with various typewriter specific pliers:
  • 3 prong pliers (total of 9 prongs) for making bends/forming typebars (especially making bends in the middle of bars rather than the end.;
  • peening bend pliers;
  • bending pliers for sideways bends esp. with thinner typebars;
  • vertical adjustment pliers (with rollers) not good for making adjustments of 3mm or more;
  • forming pliers with screws on the end to rotate heads for bending, peening and cutting;
  • peening pliers (bending by metal displacement)
• Magnetized screwdrivers
• forceps
• screw grabber (active capture)
• spring hooks (push/pull)
• nylon brushes for dusting
• needle nose pliers
• t-bender with slotted head for forming metal
• small bottles for mineral spirits and sewing machine oil. They have small metal tips for precision application.

Other than the traditional fabric-like dust covers, you might consider doing a thicker plastic/acrylic cover, particularly if you've got several machines and are using them for display purposes. I live in Los Angeles and there are half a dozen places that do this sort of custom work all the time for very reasonable rates. Searching for "plastic fabricator memoriabilia case" along with variations of plastics (acrylic, lucite, plexiglass) should get you what you want locally. (Here's a few examples I've used in Los Angeles before to give you an idea: https://solterplastics.com/, https://www.plasticfactoryinc.com/, https://www.customacrylicproducts.com/, https://plexidisplays.com/). Search for something similar in your area for easier communication and pick up/shipping.

If you search around for companies that make plastic displays, particularly for memorabilia (baseball bats, baseball cards, etc.), you can have them design and make a custom sized clear plastic box/enclosure that will keep the dust and dirt out, but still allow you to see the machine inside.
