Changing font either means swapping typebars from another machine of same brand/model or removing the slugs and soldering the slugs of desired font on there…this is expert level work. Typewriters have different pitches meaning larger/smaller letters and tighter spacing. Look for elite pitch for smaller text. A typical portable will go up to about 80 on the scale for pica (10 cpi-characters per inch) or about 100 for elite (12cpi). Some brands had even smaller pitch (up to 17cpi), particularly European brands seem to favor smaller type. Note that longer carriages will not adhere to the numbers given above.

@@someonespadre my point was that it makes sense that typewritters would type the normal size which is way smaller as seen on every book and newspaper. the size of my olympia and my olivetti are like 400% oversized compared to the size of my spanish dictionary. why is that? why we never seen such a product in the late 80's the golden era of typewritters? my father was one of the best soldering stainless steel. but is there any person that would 3D print my handwritting font? otherwise it will be another invention that won't be built for decades,

It's not inevitable but it's more common than not in my experience.

Read up on the rebel typewriter project. He does a great write up on wd-40 and the demonization of it. But to answer your question, wd-40 has paraffin wax as an ingredient and this wax can dry up and get sticky over time. You can reactivate old WD goo with new WD applied so there are use cases here. As far as the ingredient list on knocker loose, you'd have to research that. I use it. You don't have to.

@@HotRodTypewriter OK, I will look it up. The way it sounded in the vid is that you sprayed Knocker Loose on that escapement area during the diagnostic period and then, LATER on, during the cleanup phase you intended to use WD40 on the keys. I wasn't sure if you meant just the key tops or the whole keys, almost like a finishing spray. I saw a vid showing the disassembly of an Olivetti Lettera 22 and he used toothpaste on the keys to get them all shined up (interesting!) so I wanted to clarify that. You use Knocker Loose, Van Cleave uses Blaster, I've also seen some use Free All. Hard to know which one to use. I was using Simple Green, but now I'm pretty sure that's only just one part of a flush, the way you used the Orange Spray on the Voss machine rebuild.

I used WD-40 on my last 2 projects so will find out if I regret that later. I flushed it out with other products and air. I used WD-40 on the stuck sliding step gears on my Monroe calculator 2 years ago, this was before I got into typewriters since the 1970s; no issues so far. The step gears slide on a shaft and when they get stuck it jams the keyboard. They are not supposed to be oiled so probably someone oiled them decades ago. The WD-40 freed them and the machine works. So I’m skeptical of all the anti WD-40 opinions. I always blow whatever I put in there out. There’s no use softening old oil then leaving it in there to harden again.

My personal theory is WD-40 is the go to of rank amateurs who know nothing, their machine is stuck so they fill it with WD-40 and that frees it for awhile until it freezes again even worse. So technique is the problem but WD-40 gets blamed.

Sure.

I'm sure you could put new cork in there the pads are just glued in. I personally haven't tried it.

Good to know. Like I said in the video, I don't work on the newer styles as I mainly work in mid century models. Perhaps Olympia realized the flaw and pulled it for the 8. Thanks for the info!

Actually, mine is green and where your right hand side tab is, is where a return space button is
