It may sound like I’m pushing typewriter porn, but this post is really just an appeal for help. You see, I took the cover off of this Studio 21 to clean a small bit of gunk off of the escapement that was causing the tabulator function to not be able to zippily move from one tab stop to the next, and now I can’t seem to get the cover back on. ):
It came off easily enough. Unlike my Lettera 32, I didn’t even need to remove the carriage knobs – just unscrew the 4 frame screws that held the cover on, move the carriage all the way over to the left, and the cover came off easy as pie. The little bit of interior cleaning I needed to perform finished, I tried to put it back on the same way it came off, and for the life of me, it seems impossible to reverse the process. Patient examination reveals that taking off the platen knobs won’t help, either. It appears that I need to completely remove the carriage in order for the cover to go back on again, then I need to put the carriage back on afterwards.
Unfortunately, an evening of trying this and that proved to me that carriage removal on the Olivetti 21 isn’t quite the easy and obvious process that it is on the Hermes 3000. No obvious levers, and the only two obvious screws, when removed, did not seem to loosen anything, so I put them back in. I’m at a loss, and I now appeal to the smart folks of the Typosphere for help. Does anyone know how to safely remove the carriage on an Olivetti-Underwood Studio 21?
(or alternately, is there a way I’m not grokking of how to put the cover back on without removing the carriage? (:
EDIT: Gah, nevermind, I’m retarded. Turns out I set the margins too far in when I was testing with the cover off, and that kept me from being able to pull the carriage as far over to the left as it needed to be. Duh, problem solved. :P
Additional Edit: In answer to Michael Höhne’s question below, to fix the lethargic tab operation I examined (with the cover off) the linkages that the tab key engages and discovered that when you press the tab key, a part with a small felt-like pad on it comes to rest on the round rod that contains the tab set pins, just under the carriage when viewed from the rear:
This pad is probably there to purposefully slow down the carriage, likely to keep you from bending or breaking the tab pins with too forceful an impact. On mine, this pad was a bit gummy, and the bottom of that tab pin rod was slightly grimy. I found that by pushing the lever that holds this pad completely removed the tab sluggishness, so I rubbed the top of the pad with a soft cloth to clean off the gumminess and then cleaned off the bottom of the rod where the pad touches with a cloth dabbed with a drop or 2 of 3-in-one oil. Once i’d gotten rid of the dirt, the tab function once again was responsive and quick. I think you’ll find that doing this also frees up the carriage enough that the “finger slipping off the return lever” problem will be alleviated.
I think the long key throw is probably an Olivetti thing, as both mine have long throws (this 21 and a ’64 Lettera 32). However, although I think the 32 has a bit ‘lighter’ action than the 21, neither seems excessively sluggish to me, so maybe a cleaning will help yours.
As far as the crossed X and E links, I hadn’t noticed that (but it probably is on mine too), and have no idea what design decision went into that. :D
