I have the same problem (typebars not quite reaching the paper) with one of my SG1s.  As far as I can tell, the mechanism which prevents typing when you reach the right margin is not set correctly, but I can't see how to release or adjust it. 
If the typebars are moving freely, then perhaps you too have the same problem that I do.  Shall be investigating further when time permits, since the feeling is exactly the same as when the typebars are interrupted at the end of a line.
ALSO, there is a mechanism on some machines that prevents full movement of the typebars when the machine is in transit, and is assocciated with the carriage lock.  It may be worth investigating these linkages too.

Old post, I know, but did you ever find out some hard data, beak? I recently purchased a 1935 Underwood Universal with some sticky keys. Pulled it apart, cleaned it, got all the keys working, reassembled it, and.....the keys are stuck after the end of every line. I'm guessing it's the right margin stop that's caught or something as you suggested. If I tip it backwards, usually it clears and I can resume typing, but that's not really the way to go. Anybody have tips either with margin stops or Universals in general?

I'm curious, too. I have an Underwood 5 and a Royal 10 from the '20s with some keys that are now so dark it's hard to see the print. Anybody with suggestions?

Hey folks,
More foibles with my Optima. Carriage seems to drag heavily on the rails despite cleaning and a light oiling. It's so heavy that it catches sometimes and I have to jimmy the carriage a bit before it'll slide across. I'm pretty sure it's the carriage height, I've heard it's a relatively common issue and all it takes is some adjusting to find the sweet spot. Unfortunately I have no idea where those screws are and I'd hate to fumble around in there uninformed.

If anybody has an Optima and would like to show me with pictures (lots and lots of pictures ), I'd be really grateful!

For any interested party, I took it to my "local" repairman, who discovered after much tinkering that the issue was with the spacing mechanism. He adjusted it and now it works great!

So I took off the shell and looked at the innards and tried to figure out what was going on a little more. I didn't find anything to be fixed, but I did notice

1) Definite resistance on the carriage rails, perhaps the bearings are stuck or dirty

2) There's a spring underneath that does expand when the carriage actually advances, and doesn't when stuck. But this seems like a symptom, not the problem.

3) Gravity helps! When I tipped it on its left side, the carriage advanced more often than when it's resting horizontally. So is the main spring weak?

4) The carriage often catches when all the way to the left and I push it over to start a new line. I have to jiggle it before it will slide on the rails, and then I notice problem 1 again.

Well, if it's scraping, it's not moving freely. 

Why? Maybe the rails had been cleaned but not lubricated, except for a very thin film of the higher molecular weight fraction of whatever solvent mixture they had been cleaned with, which was still volatile enough that it eventually evaporated. I've noticed that white spirits - at least the kind I use - have an strong odor that lingers for days, which means some part of it takes that long to substantially evaporate. 
 

I just meant free in the sense that it does in fact move. Would that be enough to prevent the carriage from advancing? If there's a lubricant you recommend, let me know!

If you grasp a platen knob and pull the carriage release lever, does the carriage slide left and right on its rails freely? As you pull from left to right, you'll feel the tension of the draw band; does it feel normal, like there's sufficient tension?

How far you can thus move the carriage is limited by the margin settings. It's possible to have them both set toward the center of the carriage, limiting the motion to a very narrow range. It is more commonly a problem with machines that have quick-set margins, like Hermes 2000s and Royals with their Magic Margin.

Does your machine have tabs? If so, try working the tab settings and see if that helps.

Hey all, I've a new (to me) '56 Optima Elite 3. It was working great until, out of the blue, the carriage stopped advancing. The weird thing, and why I'm starting a new topic post, is that it DOES advance, only maybe 1 out of 10 strikes. 

My question is, is anybody familiar with this type of malfunction? It's not a carriage lock problem unless something is jammed oddly, it's not a drawband problem because, as I say, every tenth or so stroke the carriage will advance a space and then freeze again. So if I hit the space bar 2000 times, I might get halfway across the rails So my guess is that something is jammed, but I'm no expert and I'm hoping one of you could chime in with some ideas.

Thanks in advance.

I'd like to get something going if anyone is interested. Maybe a once a month thing, international or domestic. PM me if you like!

Maybe not identical, but certainly reminiscent, to me.
