Hi Javi
The correct term in this case is soldering. In general, soldering is when two or more pieces of metal are joined together using a joining metal that has a much lower melting point than those being joined. Soft solder which is usually a lead & tin alloy melts at temperatures between 200ºC and 400ºC depending on the alloy ratio.
Welding usually refers to heating the metals to be joined to their melting point and melting or fusing them together. Welding is a permanent join and can only be undone by cutting the metals apart. Soldering can easily be undone simply be melting the solder and separating the parts.
The only way that I'm aware of to correctly solder type slugs onto the type bars is with a soldering jig. This jig holds the slug in the typing position, the type bar is then lowered into the slug and the two are soldered together. Hope this helps,
Sky
Thanks, much appreciated!
As for the soldering process, in addition to the jig (first professional tool needed) you must have the proper "melting" metal, which comes in veeeeery thin foils and as far as I know is hard to obtain unless you take a gamble and use something different, like arts and crafts material. The catch is that the typeslug has to whitstand quite a beating, and if it´s not strong enough the typeslug will come off quite easily.

I think the idea of actually sitting and doing only one thing for a length of time is not something that people do much of anymore.
Amen to that!
In fact, I was bitten by the writing bug (or staining paper bug in my case) when I sat in front of a Lettera 32 and it just happened. Take a seat, disconnect from distractions and do something, not everthing.

Soldering (or welding, what´s the difference and which one is the correct term here?) a typeslug is tricky. As far as my experience goes, I´ve always asked Pascual and Alberto to do it for me because it´s so easy to @#*! up, and you definitely need professional tools to do it.
A former worker at the Olivetti plant in Barcelona (Angel in this case) explained me how they alligned the typebars, and a specific tool is needed. If you try to tinker with a typebar you can turn it into a postmodern steel sculpture which while it may have some artistic quality, it won´t type properly .

El aceite de los 1000 usos (the thousand uses oil), as it is marketed here. Or at least that's the brand I use, and it works wonders. That, and the weird mixture sold at the hardware store of my village which is unbeatable against nicotine stains are the true stars of my tools.

And of course, you can then go with these lessons and hit the next stubborn typewiter in the face (or wherever) with them. Its soooooo satisfying!!!
It's a coarse way of putting it, but that's the point: there's something to learn in every typewriter and there's always a reward. Enjoy the ride!

i'm really getting frustrated I can almost see the appeal of just dunking these machines in a bucket of WD-40. I've used paint thinner and mineral spirits and denatured alcohol and I can't get this Kolibri to type...
Be patient! Trust me, I've felt exactly the same as you a million times, and I bet it's just like every typewriter enthusiast in the world. I have a small army of typewriters, and maybe only a third of them performed well as they came. Another third needed time and care (and a lot of patience), and the other third... That's the "annihilated during shiping" part, the "hopeless rust bucket" section and those I can't repair on my own. The Silenta is a great example of that.
And then there's the Antares S20 I almost destroyed by dismantling it and then not being able to put it back together Correctly. But the best example is my Atlantida Style. It was sluggish, sticky keys, groaning carriage... Everything refused to move properly. What did I do? Soaking it in 3 en 1, which is the Spanish commercial name of WD-40. Result? Everything stickier than before. I had to clean EVERYTHING, and that meant taking out the rust, grime and the WD-40 which had aglutinated it all and deposited it in every moving part, spending way more time than if I had cleaned it before choking it.
Your position is absolutely understandable and I really share it, but remember that a well looked after typewriter will be there for you forever. Give it some time and the machine will return it tenfold. Take it as a challenge, every stubborn typewriter teaches a lesson about its mechanics.

You have opposite ends of the size spectrum there! Very interested to hear your impressions of the Hermes.
Totally agree!!! This looks a lot like my Hermes 9 (which is not operative right now) so any feedback is welcome.
Well, what you say about the paper support seems to be part of the cause of a common Kolibri issue: missing paper arm. If it isn't too willing to move maybe it can break off if pushed too hard.

The Kolibri! First impressions on it?

It´s also interesting how Babies improved with time. The first generation is just so-so action-wise, but those machines are definitely worth seeing, trying and keeping. Maybe you´re not going to win a speed contest with them and they´re somewhat unreliable, but they´re charming. And... Are there 1st generation Rockets?
And then, successive generations improved just everything.

The Lexicon 80 is Olivetti´s best seller in Spain ever. The venerable Hispano Olivetti Lexicon 80 (not Lexikon) was everywhere, and it stuck. It´s tough but yeah, Uwe is right to a certain point.
It has nothing to do against a SG1, but c´mon, it´s not that bad! There´s a certain run on early Lexicons which have really annoying keytops because they look nice but are too small and you can easily stick your finger between keys. In fact, there´s as much empty space as keytops, turning the keyboard into a trap fro fingers. And it has an unique feature: that weird recoil which makes typing feel like jumping on a trampoline. You press a key and the machine "lifts" it back, your finger included.
All in all, it´s extremely easy to find here in Spain and competent enough, but it´s no SG1, true. But I wouldn´t say it´s bad, either.
And nope, no paper injector. Never seen one with it, at least, and I´ve seen quite a few because as I said they´re everywhere and if you´re not careful you can trip on one, fall off and lose a couple of teeth.
Sorry, I think I´ve deviated a lot from the OP!
